PURPOSE To review patients who have presented with acute strokes from a middle cerebral artery occlusion in whom in addition to the middle cerebral artery thromboembolus, an internal carotid artery occlusion has been present, and in whom angioplasty of these totally occluded internal carotid arteries has bee n successful. METHODS We reviewed retrospectively our experience in treating a cute s...

Nine cases of carotid body tumor chemiodectomas in seven Patients are presented and diagnostic and therapeutic problems discussed Similar to other reports, many cases undergo operative exploration without correct preoper.ativ.e diagnosis or ability of the surgeon to handle such lesions. The most important factor for correct diagndsis is including carotid body in differential diagnosis of latera...

Naturally occurring collatera l pathways con necting the external carotid artery branches and the intracran ial cerebral circulation are well recognized and have been demonstrated anatomically, angiographically, and physiologically by vari­ ous flow detection devices. Under normal c ircumstances, all internal carotid artery blood flow is direc ted intracranially, and flow through the co ll ater...

Hemodynamic changes were examined with an ultrasonic Doppler flowmeter and with a sound-spectrograph in 5 patients with internal carotid giant aneurysms or with recurrent laryngeal cancer undergoing gradual carotid occlusion. The ultrasonic Doppler technique was useful for preoperative assessment of intracranial cross-filling and as a practical guide for the graded reduction of blood flow in th...

Post-traumatic sphenoid sinus pseudoaneurysm arising from the cavernous segment of internal carotidartery (ICA) is rare, and even rarer occurrence an associated carotid-cavernous fistula (CCF). Here we presentthe case a young male patient presenting with intractable epistaxis due to post-traumatic sinuspseudoaneurysm carotid artery simultaneous fistula.

Extracranial internal carotid artery occlusive disease usually produces stroke in the middle cerebral artery territory or the border zone between the middle and anterior cerebral arteries. It is unusual for occipital infarction in the posterior cerebral artery territory to be caused by internal carotid artery disease despite the fact that the posterior cerebral artery may arise directly from th...

We present a rare case of agenesis of the left internal carotid artery in a 43-year old woman, associated with an aneurysm of the anterior communicating artery and presenting with subarachnoid hemorrhage. The left internal carotid artery was not visualized on the left carotid angiogram. The left middle cerebral artery was perfused from the basilar artery via the dilated posterior communicating ...

We report a case of a ruptured aneurysm of the anomalous cerebellar artery originating from internal carotid artery presenting with a carotid cavernous fistula (CCF). An initial angiogram showed the typical appearance of a CCF with a direct fistulous tract with focal aneurysmal dilation from the ascending cavernous segment of the right internal carotid artery. A postembolization angiogram of th...

Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...
