Cervical spine injuries associated with three-point fixation lap-sash seat belts result from impact against the sash. While such injuries are infrequent and often without serious neurologic sequelae, they may produce serious deficits with grave injuries. Flexion-extension fractures of the lower cervical vertebrae, fractures of the transverse and spinous processes of the lower cervical and upper...

A 38-year-old man with Marfan syndrome presented with headache and neck pain. MR imaging revealed a large enhancing mass in the cervical anterior epidural space. Cervical laminectomy with biopsy of the lesion revealed a large engorged anterior epidural venous plexus (AEVP). Marfan syndrome may predispose the patient to enlargement of AEVP secondary to a vessel wall abnormality.

BACKGROUND Carotid endarterectomy may be performed under cervical plexus block with local anesthetic supplementation by the surgeon as necessary during surgery. It is unclear, however, whether deep or superficial cervical plexus block offers the best operating conditions or patient satisfaction. Therefore, the authors compared the two in patients undergoing carotid endarterectomy. METHODS For...

Background and Objectives: Patients undergoing thyroid surgery need postoperative pain management. Bilateral superficial cervical plexus block (BSCBs) has been shown to improve postoperative analgesia. The objective of this study was to assess its analgesic efficacy in the first 24 hours after thyroid surgery alone and when combined with bilateral deep cervical plexus block (BDCBs). Methods: We...

In the GALA trial (Dec 20, p 2132), all types of regional anaesthesia were grouped as one: “local anaesthesia”. Yet clinical and anatomical studies confi rm important diff erences between simple subcutaneous infi ltration, formal “superfi cial” cervical plexus block, and a deep block. The last two are clinically equally eff ective, anatomical investigations showing that the so-called deep cervi...

The standard anatomy textbooks of today agree that the brachial plexus in man is derived from the anterior rami of the fifth, sixth, seventh, and eighth cervical and first thoracic nerves (Fig. 1). The anterior rami of the fifth and sixth cervical nerves are described as uniting at the outer border of the scalenus medius to form the cephalic trunk, the anterior rami of the eighth cervical and f...

Dorsal root entry zone (DREZ) lesioning is a neurosurgical procedure that aims to relieve severe neuropathic pain in patients with brachial plexus avulsion by selectively destroying nociceptive neural structures the posterior cervical spinal cord. Since introduction of over 4 decades ago, DREZ technique has undergone numerous modifications, variety center- and surgeon-dependent technical differ...

A study of the submucous, periglandular and intravillous plexus of the frog has been carried out with light microscopy and conventional electron microscopy. The existence of a true Meissner plexus, with light microscopy, as well as the existence of sensitive-like structures, with light and electron microscopy have been demonstrated in the frog.

In patients with severe carotid artery stenosis who developed transient ischemic attack, carotid endarterectomy is one of the most effective treatments. In particular, in patients with contralateral carotid artery lesions, there is a risk of serious neurologic complications during the intra-operative period. Experienced staff can perform simultaneous bilateral carotid endarterectomy safely in c...
