Headache associated with cervical lesions is called cervicogenic headache and involves the occiput but not the orofacial region. However, patients occasionally present with orofacial pain accompanied by neck symptoms. This study investigates whether orofacial pain can originate from the neck and whether cervical plexus block can help in diagnosis. We enrolled eight patients suffering from chron...

Four cervicobrachial plexuses from two colugos (Dermoptera), which are gliding mammals with semi-elongated necks, were dissected with imaging analysis and compared with those in its relatives, 12 sides of six treeshrews (Scandentia) and 32 sides of 16 strepsirrhines (Primates), for considering of its evolutionary constraint and functional adaptation. (1) The relative cervical length in the ...

Irritation of neural structures, specifically the brachial plexus outside of the cervical spine is capable of producing pain in the upper extremity. These pain patterns may be similar to pain originating from the cervical spine, presenting a diagnostic challenge. Brachial plexus block is performed at multiple levels, including interscalene, supraclavicular, infraclavicular, and axillary. Inters...

We report the case of a 97 year old woman suffering from a voluminous diverticle of the cervical esophagus with important comorbidities and a very poor quality of life. A diverticulectomy under general anesthesia implied a high level of risk. Regional anesthesia was chosen, i.e. an intermediate cervical plexus block, with mild sedation allowing to maintain contact with the patient. The procedur...

Ultrasound-guided blocks of the cervical plexus are established anesthetic procedures for carotid endarterectomies. However, the innervation of the cervical region is complex and subject to relevant anatomical variability. Involved are portions of the cervical and brachial plexus and cranial nerves (IX,X-functional and sensory innervation of the arterial vessel wall; VII-platysma, XIsternocleid...

BACKGROUND General anesthesia is commonly used for surgery in the neck region. Superficial cervical plexus block is adequate to produce anesthesia in the anterior and anterolateral aspects of the neck. Our aim was to observe the effectiveness of bilateral cervical plexus block for surgery in this region of the neck. METHODS A total of 136 neck surgery cases were enrolled in this prospective u...

Pre and post-fixed variations at roots of the brachial plexus have been well documented, however little is known about the variations that exist in the branches which arise from the brachial plexus. In this paper, we describe about one such rare variation related to the dorsal scapular and the long thoracic nerve, which are the branches arising from the roots of the brachial plexus. The variati...

Thin-section computed tomography (CT) after bolus high-volume, intravenous contrast enhancement of the cervical epidural and intervertebral foraminal venous plexus was undertaken in eight patients. Visualization of exiting cervical nerve root by opacification of the surrounding intervertebral plexus was evaluated in 38 foramina. Visualization was judged as excellent in 77% and good in 21%. Thus...

Presence of a cervical rib in children is extremely rare, particularly when symptoms of compression of the lower trunk of the brachial plexus occur. We present two cases with such a condition, where two young girls, 11 and 16 years of age were treated by resection of the cervical rib after a supraclavicular exploration of the lower trunk of the brachial plexus. The procedure led to successful r...

Brachial plexuses of 110 healthy volunteers were examined using high resolution color Doppler ultrasound. Ultrasonic characteristics and anatomic variation in the intervertebral foramen, interscalene, supraclavicular and infraclavicular, as well as the axillary brachial plexus were investigated. Results confirmed that the normal brachial plexus on cross section exhibited round or elliptic hypoe...
