The sternocleidomastoid (SCM) artery supplying blood to the SCM muscle has different origins according to its anatomical segment. The authors performed cadaveric neck dissection to review the surgical anatomy of neurovascular structures surrounding the carotid artery in the neck. During the dissection, an unusual finding was cited in which the SCM artery supplying the middle part of the SCM mus...
absracta rare variant of ansa cervicalis was discovered during dissection of the neck in amale cadaver. the superior root of the ansa cervicalis was formed by the c1 ventralramus. it accompanied with the vagus nerve in place of the hypoglossal nerve and descendedinto the carotid sheath with it. moreover the c1 ventral ramus formed fromthe sheath and joined the inferior root from c2 and c3 ventr...
Transarterial embolization in the external carotid artery (ECA) territory has a major role in the endovascular management of epistaxis, skull base tumors, and dural arteriovenous fistulas. Knowledge of the potential anastomotic routes, identification of the cranial nerve supply from the ECA, and the proper choice of embolic material are crucial to help the interventionalist avoid neurologic com...
POURFOUR DU PETIT iS of interest in the history of neuroanatomy for his observations and controlled experiments which led to the correction of the earlier view that the 'intercostal nerve' is of cranial origin. The so-called intercostal nerve was the name which had been given by Thomas Willis to the sympathetic chain. This, of course, is one of the two divisions of the autonomic system which in...
Objective To report a rare case of unruptured internal carotid-posterior communicating artery (IC-PC) aneurysm splitting the oculomotor nerve treated by clipping and to review the previously published cases. Case Presentation A 42-year-old man suddenly presented with left oculomotor paresis. Three-dimensional digital subtraction angiography (3D DSA) demonstrated a left IC-PC aneurysm with a bul...
The effect of intracarotid injections of ouabain (25.0 ng) or acetylstrophanthidin (1.56 tig) on feline carotid sinus baroreceptors was evaluated using an isolated perfused carotid sinus preparation. The effects of the drugs on baroreceptor activity were determined by monitoring carotid sinus nerve activity and systemic arterial blood pressure. Administration of either drug to the isolated caro...
Three patients with nasal visual field defects are described. In each case it is believed that compression of the lateral fibres of the optic nerve by the anterior cerebral or internal carotid artery was the cause. Binasal hemianopia can thus be produced by a single lesion and is as much a true hemianopia as the common bitemporal one. The value of careful neuroradiological investigation to disp...
We describe a case of acute oculomotor nerve palsy caused by a ruptured middle cerebral artery (MCA) aneurysm. A 59-year-old female presenting with headache and nausea was admitted to our hospital. Her consciousness was alert, and had no other neurological deficit without left oculomotor nerve palsy. A computed tomography (CT) showed SAH extending from left sylvian cistern to basal cistern. CT ...
