Persistence of the hypoglossal artery is an unusual congenital abnormality of the carotid arterial system, and the simultaneous occurrence of atheromatous disease in the internal carotid artery and persistent hypoglossal artery is even more uncommon. Carotid surgery in this situation is challenging, and the surgeon must be aware of potential inherent pitfalls. A 74-year-old woman with asymptoma...

Introduction: Internal carotid artery-posterior communicating artery aneurysms (ICPCANs) are occasionally located under the anterior petroclinoid fold (tentorium). The tentorium must be resected to achieve safe and secure clipping of ICPCAN. surgeon performing procedure careful not damage oculomotor nerve, which is usually behind aneurysm, ensure that patient's function preserved. In this artic...

Internal carotid arterial dissection is a relatively rare condition that can cause neck pain and/or ischemic symptoms. Cranial nerve palsy caused by internal extremely rare. A 39-year-old male massaged his with fingers. He experienced transient pain. After one week, he demonstrated hypoglossal palsy. The radiological studies revealed extracranial dissection. Cervical self-massage may and For th...

the carotid is a small mass of chemoreceptor's and sustentacular cells that detects changes in the composition of the arterial blood. the aim of the present study was to identify the size, color, location, blood and nerve supply of the carotid body in makouei sheep. fourteen heads of sheep from both sexes were collected from urmia public slaughter-house. the exact situation and nerve supply of ...

Using immunohistochemistry, we studied the origins and pathways of parasympathetic and sensory nerve fibers to the pial arteries in four squirrel monkeys. Following its application to the surface of the middle cerebral artery, the retrograde axonal tracer True Blue accumulated in parasympathetic neurons of the sphenopalatine ganglion and the internal carotid ganglion. The latter is strategicall...

background: the presence of significant carotid stenosis in coronary artery bypass grafting (cabg) patients increases the risk of either transient ischemic attack or stroke. however, there is a dearth of data on the risk for patients with unilateral total occlusion of the carotid artery. we herein report our results of cardiac surgery in patients with unilateral total occlusion of the carotid a...

A 70-year-old woman presented with headaches and recurrent stroke symptoms. During five years, the patient has been treated for cerebral infarction associated with severe atherosclerotic stenosis of the internal carotid artery. Three-year follow-up magnetic resonance angiography showed a tiny de novo aneurysm arising from the distal part of atherosclerotic internal carotid artery. And 5-year fo...

The traditional presentation of spontaneous internal carotid artery dissection includes ipsilateral hemicranial headache, oculosympathetic paresis, and contralateral focal cerebral ischemic deficits. However, we describe two cases with multiple cranial nerve involvement ipsilateral to the dissection as the principal feature. The first patient, a 36-year-old man, had involvement of the 9th, 10th...

A 51-year-old man experienced the onset of positionally dependent neurologic changes . When he turned his head to the left and extended his neck for longer than 3 sec he became dizzy and experienced a sensation of "numbness" over his right body, including his face. This was accompanied by loss of motor control of the right body. He had some blurring of vision during these episodes but no loss o...
