Intracranial internal carotid artery stenosis.
The advent of EC/IC Bypass surgery has focused attention on selected patients who might benefit from this innovative procedure. There is a poverty of natural history data pertaining to all such lesions. Two centres (Memphis, Tennessee and London, Ontario) pooled their resources to carry out a retrospective review of 58 patients with angiographically-proven intracranial internal carotid artery s...
متن کاملBilateral Internal Carotid Artery Stenosis
A72-year-old manpresented with paroxysmal and transient involuntary movements, or "limb shaking". The attacks occurred alternately from one side of the body to the other and ceased spontaneously. Surface EMG study showed synchronous grouping discharges in multiple limb muscles, being compatible with hemiballism-hemichorea. Cerebral angiography demonstrated marked stenosis of the bilateral inter...
متن کاملPoststenotic flow and intracranial hemodynamics in patients with carotid stenosis: transoral carotid ultrasonography study.
BACKGROUND AND PURPOSE In severe carotid stenosis, blood supply via the poststenotic internal carotid artery (ICA) and collateral pathways determine cerebral perfusion. We investigated whether poststenotic flow on transoral carotid ultrasonography (TOCU) is predictive of cerebral hemodynamics. METHODS Eighty-eight patients with unilateral carotid stenosis underwent TOCU to analyze blood flow ...
متن کاملManagement of asymptomatic internal carotid artery stenosis.
Optimal management of patients with asymptomatic carotid artery stenosis remains unclear. Although 2 high-quality randomized clinical trials demonstrated reductions in ispsilateral stroke rates in patients without symptoms after carotid endarterectomy, medical therapy of asymptomatic carotid artery stenosis has reduced rates of stroke to approximately 1% per year, raising questions about the ge...
متن کاملCarotid angioplasty and stenting in a patient with high grade stenosis of Internal Carotid Artery associated with both vertebral arteries and contralateral carotid occlusion
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...
