BACKGROUND AND PURPOSE Vertebrobasilar territory ischemia (VBI) leads to disabling neurological symptoms and poses a risk for stroke by an embolic or flow-related mechanism. We present our clinical experience in the endovascular treatment of patients with symptomatic VBI from severe atherosclerosis or dissection of the vertebral and subclavian arteries that(More)
We describe a previously unreported complication of the use of Guglielmi detachable coils and Mechanical detachable spirals in endovascular treatment of intracranial aneurysms. We document four cases in which migration of part of a coil into the parent artery occurred after completion of the procedure. Possible mechanisms are discussed.
OBJECTIVE Cerebral hyperperfusion syndrome is a recognized complication of carotid endarterectomy, with a reported incidence of 0.3 to 1.2%. The incidence of cerebral hyperperfusion after endovascular revascularization procedures of the craniocervical arteries remains unknown. We evaluated the incidence of cerebral hyperperfusion syndrome in our(More)
OBJECTIVE The balloon-assist or neck-remodeling technique is an adjunctive method devised for the endovascular coil embolization of aneurysms characterized by a wide neck or unfavorable geometric features. Since its initial description, there have been few data to corroborate its utility, efficacy, and safety in aneurysm embolization. METHODS Twenty(More)
OBJECTIVE AND IMPORTANCE The goal of this report was to describe the successful percutaneous endovascular use of a Gianturco-Roubin-2 coronary stent in the treatment of an acute atherothrombotic occlusion of the basilar artery. To our knowledge, the percutaneous endovascular deployment of an intra-arterial stent for the treatment of an acute(More)
OBJECTIVE We describe a consecutive series of patients treated with endovascular stent-supported coil embolization for symptomatic or enlarging wide-neck and fusiform aneurysms and pseudoaneurysms of the carotid and vertebrobasilar arteries. METHODS Seven stent-supported coil embolization procedures were performed for seven aneurysms in seven consecutive(More)
BACKGROUND AND PURPOSE We sought to describe the clinical outcome and angiographic results obtained in the endovascular therapy of ruptured posterior circulation cerebral aneurysms using Guglielmi detachable coils (GDC) over a 7-year period. METHODS A retrospective analysis was performed of 112 patients evaluated at the University of California at San(More)
BACKGROUND AND PURPOSE Dissection of the carotid artery can, in certain cases, lead to significant stenosis, occlusion, or pseudoaneurysm formation, with subsequent hemodynamic and embolic infarcts, despite anticoagulant therapy. We sought to determine the therapeutic value of stent-supported angioplasty retrospectively in this subset of patients who are(More)
Domestic violence leading to strangulation by an abusive spouse can cause carotid artery dissection. This phenomenon is rare and has been described in only three previous instances. The authors present their management strategies in three additional cases. Three young women aged 24 to 43 years were victims of manual strangulation committed by their spouses(More)
OBJECTIVE AND IMPORTANCE Intimal dissection constitutes one of the complications associated with angioplasty of intracranial vessels. We present a case of iatrogenic dissection of the entire basilar artery, which was induced by angioplasty and stenting of symptomatic, focal, intracranial vertebral artery stenosis, and its successful treatment with tandem(More)
