Plexus cervicalis

The second major ventral branch of the cervical plexus forms the inferior root of the ansa cervicalis (or ansa hypoglossi). The superior root is formed by C1 fibers (described above) and is termed the descedens hypoglossi. The fibers comprising the inferior root are variable. Loukas et al. reported that fibers came from C3 alone in 40% of cases, C2 and C3 in 38%, C2 alone in 12%, and C2, C3, and C4 in 10% (Loukas et al., 2007). In 75% of cases, the ansa cervicalis runs posterolaterally to the internal jugular vein; in other cases, it runs anteromedially. The length of the ansa cervicalis is said to have a long root when the union of the superior and inferior roots is inferior to the omohyoid. Seventy percent of patients have a long ansa cervicalis (Loukas et al., 2007). The branches of the ansa cervicalis innervate the infrahyoid muscles. These muscles are the omohyoid (both the superior and inferior bellies), the sternohyoid, and the sternothyroid.

  2. The deep cervical plexus branches also supply the muscles with nerves. Fibers from the C1 posterior primary ramus supply the deep neck muscles, and some of these fibers join up with the hypoglossal nerve to supply the thyrohyoid and geniohyoid muscles with nerves. The C1 and C2 primary ramus fibers form the superior root of the ansa cervicalis, a loop of nerves that makes up part of the cervical plexus, while C2 and C3 fibers form the inferior root of this group of nerves. The ansa cervicalis supplies the strap muscles, while C2, 3 and 4 fibers, along with the spinal accessory nerve, supplies various scapular muscles.

If you believe that this Physiopedia article is the primary source for the information you are refering to, you can use the button below to access a related citation statement.The sensory nerves are gathered closely together at the nerve point. For this reason, it is a popular choice for anesthetic nerve blocks. There have been numerous reports of both BP and cervical plexus injuries associated with these procedures (Christ, Rindfleisch, & Friederich, 2009). Because of this risk, several techniques exist to avoid the nervous structures while providing anesthesia, including ultrasound guidance (Herring, Stone, Frenkel, Chipman, & Nagdev, 2012) and infiltrating in the subcutaneous tissue only, along the posterior border of the SCM, which appears to be equally effective as a directed nerve block (Ramachandran, Picton, Shanks, Dorje, & Pandit, 2011).The cervical plexus is considered to be constituted from the ventral roots of spinal nerves C1 to C4, strictly speaking (Figure 4.26), while the brachial plexus takes up C5–C8. Since there is overlap between cervical and brachial plexuses, branches of C3 and C4 can participate in the brachial plexus, while brachial plexus nerves can join in their trajectory the nerves originating from cervical plexus (Lanz and Wachsmuth, 2004).Der Plexus cervicalis ist ein Nervengeflecht, das aus den anterioren Ästen (Rami) der Spinalnerven der Segmente C1 bis C4, mit Anteilen von C5, gebildet wird.

Looking for definition of plexus cervicalis? plexus cervicalis explanation. plexus cervicalis - a nerve plexus lying beneath the sternocleidomastoid muscle The superficial (cutaneous) branches emerge near the middle of the dorsal border of the sternocleidomastoid muscle (the region known as the punctum nervosum). These divide into ascending and descending branches. The ascending branches are the lesser occipital (C2-C3), great auricular (C2-C3) and transverse cervical (C2-C3) nerves. The descending branches are the supraclavicular (C3-C4) nerves. The deep (muscular and communicating) branches are divided into lateral and medial branches. The lateral branches are to the sternocleidomastoid (C2-C4), trapezius (C3-C4), levator scapulae (C3-C4), and scalenus medius muscles (C3-C4), and communicating branches are to the accessory nerve (C2-C4). The medial branches are to prevertebral muscles (C1-C4), to infrahyoid muscles (C1-C3) (by way of ansa cervicalis) and to the diaphragm by way of the phrenic nerve (C3-C5). Communicating branches to the vagus nerve (C1-C2), hypoglossal nerve (C1-C2), and to the superior cervical sympathetic ganglion (by gray rami communicantes, C1-C4) also arise from the medial branches. Although classical textbooks imply that all the motor input to the trapezius muscle is from the spinal accessory nerve, fibers from the cervical plexus (C3-C4 nerves) have been shown to carry an additional motor supply to trapezius, independent of the accessory nerve (Stacey et al., 1995; Kierner et al., 2001).

  2. The phrenic nerve can also be approached during a formal comprehensive neck dissection (radical neck dissection or modified radical neck dissection). The appropriate incision would have been made and the dissection has progressed from the anterior border of the trapezius muscle in a forward direction, removing all nodal contents from the floor of the posterior triangle of the neck. The transverse cervical vessels would have been ligated as part of the procedure and, also, the posterior belly of the omohyoid muscle would have been divided. Further forward, the brachial plexus will be seen to be running in an inferolateral direction. The dissection continues medial to this and under the internal jugular vein until the scalenus anterior muscle is reached, where the phrenic nerve will be located. This can be recognized because it is running in an inferomedial direction (Figure 14.8).
  3. In humans, the cervical plexus is a plexus of the ventral rami of the first four cervical nerves (C1-C4). Each nerve, except for C1, divides into an ascending and a descending branch, which unite with branches of contiguous nerves to form loops. These loops and their branches form the cervical plexus. Each ventral ramus receives one or more gray rami communicantes from the superior cervical ganglion of the sympathetic trunk. The cervical plexus lies ventral to the scalenus medius and levator scapulae muscles, deep to the sternocleidomastoid muscle and the internal jugular vein. From this plexus arise cutaneous and muscular branches to the head, neck, and shoulder, and communicating branches to the vagus, hypoglossal and sympathetic nerves.

There are two important ventral branches of the cervical plexus. The first is the phrenic nerve. The phrenic nerve receives its fibers chiefly from C4, but also receives contributions from C3 and C5. The phrenic nerve runs inferiorly with the internal jugular vein, but has a different course on the left than the right. On the left, it crosses the anterior scalene anterior to the first part of the subclavian artery. On the right, this crossing occurs anterior to the second part of the subclavian artery. The C5 fibers of the phrenic nerve may form an accessory phrenic nerve in the neck and go on to join the phrenic nerve proper in the root of the neck or thorax.

The cervical plexus lies deep to the sternocleidomastoid muscle. Its branches convey motor fibers to many cervical muscles and to the diaphragm. Its sensory fibers convey exteroceptive information from parts of the scalp, neck, and chest as well as proprioceptive information from muscles, tendons, and joints. Sympathetic sudomotor and vasomotor fibers travel with this plexus to blood vessels and glands. The superficial branches perforate the cervical fascia to supply cutaneous structures; the deep branches supply mainly muscles and joints.

Size kısaca bunun hakkında bilgi verelim The cervical plexus, composed of the anterior rami of C1 to C4 cervical roots, innervates most neck muscles and provides sensory innervation to anterior and lateral neck. Cervical plexopathy commonly occurs as a result of direct invasion from contiguous neck soft tissue tumors or indirectly from regional lymph node metastases from head and neck squamous cell carcinomas, lymphoma, or lung and breast adenocarcinomas.100,101 Involvement of the cervical plexus is less common than the brachial or lumbosacral plexus.101

Akciğer tuberkulozu vb. durumlarda phrenicektomi yapılarak akciğerin fazla çalışması önlenir.The ansa cervicalis, formerly called ansa hypoglossi, is formed by the union of the ventral rami of the first three cervical nerves through two main roots, the superior and inferior (Olry and Haines, 2002). The superior root (descendens hypoglossi) contains fibers from C1. It first travels within the sheath of the hypoglossal nerve and than in the carotid sheath to join the inferior root to form the ansa cervicalis. The inferior root, named the descending cervical nerve, contains fibers from C2-C3 spinal nerves. It descends on the dorsolateral side of the internal jugular vein. The ansa cervicalis is located deep to the sternocleidomastoid muscle and overlies or may sometimes lie within the carotid sheath, usually where the superior belly of the omohyoid muscle crosses over the internal jugular vein (Tubbs et al., 2005). Sometimes the ansa is located superior (short ansa) or inferior (long ansa) to the omohyoid muscle (Caliot and Dumont, 1983). The branches of ansa cervicalis innervate the infrahyoid muscles. The ansa cervicalis is usually in a ′concentrated′ form, characterized by thick nerve trunks constituting a solitary arch from which one or two branches for the infrahyoid muscles emerge. Rarely, it has a ′diffuse′ form characterized by finer nerve trunks in the form of a plexus (Poviraev and Chernikov, 1967).Patients with metastases of the cervical plexus typically complain of pain within the submandibular and subglottic area, posterior or lateral neck, or around the shoulder. Coughing, neck movement, or assuming a recumbent position exacerbates the pain. Sensory loss commonly develops along the C2, C3, and C4 dermatomal distribution. This is in contrast to sensory loss from surgical neck dissection, which occurs in the distribution of the superficial branches of the greater auricular nerve or transverse cervical branches. Involvement of the distal spinal accessory nerve produces partial trapezius and sternocleidomastoid weakness. Paralysis of the hemidiaphragm, causing dyspnea when supine or upon exertion, results from phrenic nerve involvement.100,101

  2. The phrenic nerve usually arises from C3-C5 nerves approximately at the mid-level of the thyroid cartilage. It gives off sensory fibers to mediastinal pleura and pierces the diaphragm to supply it on the caudal surface. Sometimes, an accessory phrenic nerve is present as a contribution to the phrenic nerve from the ventral ramus of C5, derived as a branch from the nerve to the subclavius muscle. The accessory phrenic nerve may sometimes arise from C4 or C6 segments or from the ansa cervicalis. It travels lateral to the phrenic nerve and joins the phrenic nerve at the root of the neck or in thorax.

The cervical plexus anatomy consists of the upper four cervical nerves. The lower three divide into branches, which either ascend or descend to form the plexus. The plexus consists of several branches, including a superficial cervical plexus, which supplies the cervical fascia, the head and neck skin and parts of the ear and face. A deep set of plexus nerves reaches the neck muscles and the upper back. The phrenic nerve arises from the fourth cervical nerve and enters the diaphragm through the thorax, breaking into more branches, which pierce the muscle and spread out under the surface, supplying it with nerves.Copyright © 2020 Elsevier B.V. or its licensors or contributors.

The muscular targets of the ansa cervicalis are the infrahyoid muscles. The motion of the hyoid bone is involved in swallowing and mastication, but this motion is largely dependent on the muscles of oropharynx and pharyngeal constrictors and will continue to function appropriately even with infrahyoid muscle denervation (Ishida et al., 2002). This makes it an excellent donor for reinnervation procedures for injuries to the RLN. Another factor that makes the ansa cervicalis ideal for this purpose is that it is normally activated during phonation and swallowing (Loukas et al., 2007; van Lith-Bijl & Stolk, 1997). plexus cervicalis — [TA] cervical plexus: a nerve plexus formed by the anterior branches of the upper four cervical nerves; arranged as an irregular series of loops, it gives off superficial branches (lesser..

What is the Cervical Plexus? (with pictures

The cervical plexus is formed from the anterior primary rami of C1–C4, deep to the sternocleidomastoid muscle and in front of the scalenus medius and levator scapulae muscles. Sensory branches include the greater and lesser occipital nerves, great auricular nerve, cutaneous cervical nerves, and supraclavicular nerves. The motor branches include the ansa hypoglossi, branches to scalenus medius and levator scapulae muscles, the phrenic nerve, and branches to the spinal accessory nerve. Lesions of the cervical plexus are uncommon, usually resulting from trauma, mass lesions, or as sequelae to surgery such as carotid endartectomy. Involvement of motor branches results in disruption of muscular function, such as shoulder elevation and head rotation and flexion with spinal accessory nerve damage. Involvement of sensory branches results in loss of cutaneous sensation or in pain and paresthesias in regions of the head or neck supplied by these branches.

Brachial Plexus Injury Caused by Cervical Rib Anomaly

Deep and superficial cervical plexus blocks can be used in a variety of surgical procedures, including superficial surgery on the neck and shoulders and thyroid surgery This nerve comes from the cervical plexus (roots C3, C4, and C5). It runs from lateral to medial in a downward direction on the surface of the scalenus anterior muscle. To reach the nerve individually a short transverse incision will be made in the supraclavicular area just lateral to the lateral border of the sternocleidomastoid muscle. The investing fascia is incised along the upper border of the clavicle to gain access to the deep compartment of the neck. The dissection continues medially between the transverse cervical vessels above and the subclavian vein below until the internal jugular vein is located. The dissection continues deep to the internal jugular vein in a medial direction. Once the prevertebral fascia is reached, the fatty and lymphatic contents of the neck can be retracted in an upward direction to expose this fascia. Deep to this area would be the brachial plexus. To reach the phrenic nerve, the dissection now continues in a medial direction to the lateral border of the scalenus anterior muscle. The phrenic nerve is encountered running on the surface of the muscle from lateral to medial (Figure 14.17).The great auricular nerve is from the cervical plexus as a superficial branch, originating from the second and third cervical vertebral levels (C2–C3). The great auricular nerve exits the cervical plexus at the posterior aspect of the sternocleidomastoid muscle at a point called Erb’s point. Erb’s point is where some of the cervical nerves converge and can also be where the great auricular and accessory nerves are encountered. It is defined as “a circumscribed point, about 2–3 cm above the clavicle, somewhat outside of the posterior border of the sternomastoid and immediately in front of the sixth cervical vertebra” (Landers and Maino, 2012). It can also be thought of as being found along the posterior border of the sternocleidomastoid at about 6.5 cm inferior to the external auditory canal as a 3 cm circle there (Gloster, 2008).Intrinsic tumors of the brachial plexus can be divided into neural sheath and non-neural sheath subtypes. Benign neural sheath tumors are the most frequent type and consist of neurofibromas or schwannomas. Malignant neural sheath tumors are either malignant schwannomas or neurogenic sarcomas. Schwannomas more commonly involve the upper plexus (Ganju et al., 2001). Neurofibromatosis type 1 can be associated with multiple nerve tumors, and more diffuse spread is observed (MacCollin et al., 2005).

Plexus cervicalis Electrodiagnosis with electromyography (EMG) and nerve conduction velocity (NCV) is helpful to delineate the topographic aspects of the lesion. EMG in radiation-induced plexopathy often presents with myokymic discharges.The great auricular nerve is also prone to injury. As mentioned above, it is frequently the culprit in pain and sensory disturbance after rhytidectomy. This injury is thought to be the result of inadequate release of the subauricular membrane (Rohrich, Taylor, Ahmad, Lu, & Pessa, 2011). Other causes of great auricular nerve injury have been reported in the literature, including hanging and other neck surgeries (Arias, Arias-Rivas, Pérez, & Alende-Sixto, 2005). When injury develops, treatment is based on the specific anatomic diagnosis of the nerve. Often it is a neuropractic injury that will recover spontaneously. In other cases it may require surgical decompression (Barbour, Iorio, & Halpern, 2014), or amputation/neurolysis of a painful neuroma (de Chalain & Nahai, 1995). When the nerve is severed, direct repair should be attempted if possible (de Chalain & Nahai, 1995). Due to its nature as a pure sensory nerve, the great auricular nerve may serve as a donor for nerve grafting/repair (Messner et al., 1995).The management of neoplastic brachial plexus lesions is most frequently RT. RT with 3000–5000 cGy produces significant pain relief (Kori et al., 1981). Motor and sensory deficits respond less well. The tumor can spread to involve the entire brachial plexus, resulting in complete paralysis. Autonomic changes may occur. Lymphedema and venous obstruction or thrombosis are late complications. Pain relief must be obtained by pharmacological treatment, usually opioids by either oral or spinal administration. Treatment of neuropathic pain is an essential supportive measure. Surgery is reserved for selected cases with neurological deficit (Lusk et al., 1987). In tumor recurrence, a repeat course of RT is also based on an individual decision. Chemotherapy and hormonal therapy can produce additional pain relief. Pain treatment is the most important feature for patients, either pharmacological or by local nerve blocks or other invasive techniques. In the older literature, even limb amputation for pain management has been described (Kori et al., 1981; Ischia et al., 1985).

What does plexus cervicalis mean? definition, meaning and audio

Looking for online definition of plexus cervicalis in the Medical Dictionary? plexus cervicalis explanation free. Meaning of plexus cervicalis medical term. What does plexus cervicalis mean Injury to the various nerves of the cervical plexus presents with various clinical symptoms related to the specific function of the nerves. Injury to the posterior branch nerves usually causes a syndrome of pain or sensory loss in the specific distribution of the affected nerve. The lesser occipital nerve has also been implicated in the development of occipital neuralgia and headache syndromes. Ducic et al. described this phenomenon in a series of patients following craniotomy, as well as their successful treatment with excision of the offending nerve (Ducic, Felder, & Endara, 2012). Precipitating factors for lesser occipital nerve injury other than craniotomy have been described as well. Sensory disturbance of the ear is common after rhytidectomy and this is largely thought to be secondary to great auricular nerve injury, but the lesser occipital nerve may play an important role as well (Pantaloni & Sullivan, 1999; Rees & Aston, 1978). Other rarer causes of lesser occipital nerve injury have been described, including as a complication of posterior neck dissection (Hu et al., 2013) and shoulder surgery (Tahir & Corbett, 2013).

Seemingly Lanz and Wachsmuth belong to lumpers indicating only few variations (four) from their general pattern, while Bannehka should be considered a splitter, trying to catch all variations. A middle position is taken by Caliot and Dumont (1986), which seemingly has good clinical reference (see Chhetri and Berke, 1997). plexus cervicalis. Also found in: Dictionary, Medical, Encyclopedia, Wikipedia. Synonyms for plexus cervicalis. a nerve plexus lying beneath the sternocleidomastoid muscle The reviews on the ansa cervicalis (Caliot and Dumont, 1986; see also Chhetri and Berke, 1997) show seven morphological forms of the ansa cervicalis (Figure 4.27), in which A is the double classic form found in 40%, B the simple classic form in 27%, C the double form with two separate roots in 11%, D is called the triple form in 9%, E the double short form in 8%, F the quadruple form in 1%, and G the single short form in 1% of 80 dissections (Caliot and Dumont, 1986). Absence of the ansa was reported in two out of the 80 dissections and case reports on these cases can be found (Abu-Hijleh, 2005). An even more refined classification is described by Banneheka (2008b) in seven main groups with 21 subgroups based on the inferior root.The cervical plexus lies on the ventral surface of the medial scalene and levator scapulae muscles. It is formed by ventral rami of the cervical nerves C1 through C4. Each ramus at the C2, C3, and C4 levels divides into two branches, superior and inferior. These in turn unite in the following way: superior branch of C2 with C1, inferior branch of C2 with superior branch of C3, inferior branch of C3 with superior branch of C4, and inferior branch of C4 joins C5, to become part of the brachial plexus. Terminal cutaneous, muscular, and communicating branches supply skin and muscles in the occipital area, upper neck, supraclavicular, upper pectoral region, and diaphragm.The article Ansa Hypoglossi or Ansa Cervicalis? That’s the question … by Olry and Haines (2002), ends: “As far back as in 1835, Christophore Ernest Bach claimed that the ansa cervicalis contained only fibers arising from the cervical plexus. It took one hundred and twenty years to acknowledge that he was right …” The Ansa indeed contains cervical fibers. Renewed interest in the Ansa came from ansa hypoglossi-to-recurrent laryngeal nerve anastomosis in cases of cricothyroid reinnervation and in total laryngeal transplantation (see Paniello, 2004): the ansa cervicalis can be a source for nerve transfer.

The cervical plexus is invaded primarily by ENT tumors (Mendes et al., 2004). Often these tumors also invade the lower CNs, either directly or by invasion of the base of the skull. The large extracranial vessels may also be involved. Dull and aching pain with a neuropathic component is often the presenting syndrome in cervical plexopathy. In cervical plexopathies, pain is located around the shoulder and in the distribution of the cutaneous branches (Vecht et al., 1992). Caudal CN lesions can occur, and the phrenic nerve may also be damaged.Ansa cervicalis (ansa hypoglossi): C2,3’den çıkan liflerin oluşturduğu radix inferior (n. descendens cervicalis) ile, önce n. hypoglossus’a katılan ve sonra ondan ayrılan C1’e ait liflerin oluşturduğu radix superior’un (n. descendens hypoglossi) birleşmesi ile oluşan bir sinir ansıdır.

Neurological signs such as motor, sensory, and autonomic involvement may be delayed, and the neurological examination may be normal at the onset of symptoms. Numbness or paresthesias are often perceived in the fourth and fifth fingers. Sensory loss in the medial upper arm may be confused with lesions of the intercostobrachial nerve, which can be damaged in radical mastectomy. Weakness begins in the small hand muscles, followed by weakness of the finger flexors. Damage to the sympathetic trunk causes Horner syndrome, which can also signal centripetal spread.Diafragma’yı uyaran esas motor sinirdir. Pleksus’un en uzun siniridir. Liflerinin çoğu C4’den çıkar.

Figure 14.17. Phrenic nerve on surface of scalenus anterior. A = scalenus anterior, M = scalenus medius, P = phrenic nerve, B = brachial plexus.The cervical plexus is a group of nerves that make up the back of the head, the neck and the shoulders. There are four primary rami in both the posterior and anterior parts of the head; a ramus is a nerve branch. The anterior primary rami form the cervical plexus and are smaller than the posterior primary rami. The cervical nerve plexus makes up the skin on the anterior of the head and the lateral part of the neck, reaching to just underneath the clavicle. The plexus also supplies the neck muscles, which include the scalenes and strap muscles, and the diaphragm.Der Plexus cervicalis entsendet motorische Äste zur ventralen Halsmuskulatur, zur infrahyalen Muskulatur (untere Zungenbeinmuskeln), sowie zum Zwerchfell. Seine sensiblen Äste ziehen zum Ohr, zum Hals, zur Haut über dem Schlüsselbein und zur Schulter. In patients with malignant brachial plexopathy (Kori et al., 1981), pain starts in the shoulder and may spread to the medial and posterior aspect of the upper arm and medial forearm. Axillary pain may be an indicator of upper thoracic root involvement (Rubin and Shuster, 2006). Depending on the topographical site of involvement, radicular pain syndromes also occur.

Cervical and Brachial Plexus

plexus cervicalis的英文翻译是什么意思,词典释义与在线翻译: 英英释义. Noun plexus cervicalis的相关资料 Brachial plexopathy may also be due to subclavian artery occlusion (after radiation), thrombosis of the axillary or subclavian vein, genetic susceptibility for the development of nerve sheath tumors (neurofibromatosis), and neuralgic amyotrophy (Pezzimenti et al., 1973; LaChance et al., 1991). Specific pain syndromes, such as postmastectomy syndrome, which is typically a lesion of the intercostobrachial nerve, or neuroma formation, post-thoracotomy syndrome, or ‘phantom limb or stump’ pain of the mamma may occur.After leaving the vertebral column cervical ventral rami innervate the levator scapulae and rhomboid muscles by the dorsoscapular nerve. The literature indicates that the levator C2 to C5 and the rhomboid C3 to C6 can be involved with a variance from one to several cervical ventral rami (for references see Malessy et al., 1993). Traumatic brachial plexus lesions together with anatomical dissections established that the levator scapulae is innervated by segmental branches of C3 and C4, while the rhomboid muscle is also innervated by two segmental branches from C4 and C5 (Malessy et al., 1993). The results of Frank et al. (1997) show C3, C4 via cervical plexus and C5 via the dorsoscapular nerve to be involved in levator scapulae innervation. Recent anatomical dissections indicate that the origin of the dorsoscapular nerve from one segmental ramus is present in 18% of the cases, from a common trunck with the long thoracic in 30%, from C4 in 28% and from C4 to C5 in 23% of the cases, while one segmental ramus is taken as being usual for this nerve (Ballesteros and Ramirez, 2007). The origin from only one cervical ventral ramus (C5) is only kept by Harris (1904) and Hirasawa (1931); all other publications (12 references) favor a multiple origin.

The great auricular nerve then ascends obliquely across the sternocleidomastoid muscle to supply the skin over the parotid gland and over the mastoid process, together with both surfaces of the auricle.The cervical plexus is located deeply in the upper part of the neck, under cover of the internal jugular vein and the sternocleidomastoid muscle. It is formed by the ventral rami of the first four cervical nerves. The superficial cutaneous branches of the plexus are the lesser occipital, great auricular, transverse cervical nerves, and the supraclavicular nerves. All of these branches emerge near the middle of the posterior border of the sternocleidomastoid muscle.

The cervical, brachial, lumbar, and sacral plexuses constitute the primary plexuses of the peripheral nervous system (PNS), with the lumbar and sacral plexuses typically discussed together as the lumbosacral (LS) plexus. Neoplastic processes may involve any of these plexuses and, typically, have significant adverse effects on patient quality of life. When misattributed to other orthopedic or neuromuscular conditions, therapeutic delays further adversely affect outcome. In general, patients with metastatic involvement have advanced neoplastic spread and die from vital organ complications. To improve survival and quality of life, clinicians must possess an understanding of plexus anatomy, the clinical features associated with plexopathies and the diagnostic and therapeutic options available.

Cervical and brachial plexus

Figure 3. Schematic representation of the cervical and brachial plexus network. Cervical plexus (C1–C4): ventral rami C2, C3, and C4 divide, giving off a superior and inferior branch at each level. Superior branch of C2 and C1 ramus unite to form the ansa cervicalis. Adjacent inferior and superior branches of C2, C3, and C4 merge and give off lesser occipital, greater auricular, transverse cervical, supraclavicular, and phrenic nerves (unmarked). Brachial plexus (C5–T1): superior, middle, and inferior trunks are formed by ventral rami of C5/C6, C7, and C8/T1, respectively. Each trunk divides into anterior and posterior divisions. Anterior divisions of the superior and middle trunks form the lateral cord; anterior division of the inferior trunk becomes the medial cord and posterior divisions of all three trunks unite to form the posterior cord. Major nerves of the arm: median, ulnar, and radial receive contributions predominantly from lateral, medial, and posterior cords, respectively.The brachial plexus has a complex structure: upper plexopathy, lower plexopathy, and panplexopathy are differentiated. Because of the vicinity to lymph nodes and the apex of the lung, lower brachial plexus lesions are frequently the presentation of neoplastic involvement, whereas upper brachial plexus lesions are usually caused by RT. Neoplastic brachial plexus involvement has been described extensively in lung and breast cancer, and needs to be distinguished from other causes, such as radiation plexopathy. Infiltration of supraclavicular lymph nodes, resulting in damage of fibers from C5 and C6 nerves, is rare.Early complications are rare (Churn et al., 2000), whereas late complications are more frequent and have to be distinguished from neoplastic recurrence. The median interval between RT and the onset of RT-induced plexopathy ranges from 1 to 4 years. Delayed RT brachial plexopathy has an insidiously progressive course. Sensory symptoms, weakness, and atrophy are more prominent than pain. Lymphedema occurs more frequently in radiation plexopathy and imposes a severe reduction on the quality of life of patients. The incidence of complications increases with the total radiation dose and dose per fraction (Johansson et al., 2002). Brachial plexus lesion during mantle field radiation have also been described (Wadd and Lucraft, 1998). The general impression is that, with modern radiation techniques, the frequency of radiation plexopathy is decreasing.
