BACKGROUND AND PURPOSE The previous decade has witnessed increasing application of Guglielmi detachable coils (GDCs) for the treatment of intracranial aneurysms. However, the midterm angiographic and clinical outcomes are not well documented. We report here the angiographic and clinical outcomes of patients treated with GDCs over an 8-year period. METHODS(More)
BACKGROUND AND PURPOSE The published results of treating internal carotid artery aneurysms with the PED do not necessarily apply to its use in the posterior circulation because disabling brain stem infarcts can be caused by occlusion of a single perforator. In this multicenter study, we assessed the safety of PED placement in the posterior circulation. (More)
BACKGROUND Large or giant complex vertebrobasilar junction aneurysms have a dismal natural history and are often challenging to treat with standard endovascular or neurosurgical techniques. OBJECTIVE To report initial experience with endovascular treatment of these aneurysms using flow-diverting stents (FDS). METHODS Ten patients with FDS treatment of(More)
PURPOSE To describe the endovascular treatment and clinical outcome in patients with indirect carotid cavernous fistulas (CCFs) over a 15-year period. To our knowledge, this is the largest series in the medical literature. DESIGN Interventional case series. METHODS A retrospective evaluation of 135 consecutive patients who underwent examination and(More)
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)
BACKGROUND AND PURPOSE A number of flow-diverting devices have become available for endovascular occlusion of cerebral aneurysms. This article reports immediate and midterm results in treating unruptured aneurysms with the PED. MATERIALS AND METHODS A prospective registry was established at 3 Australian neurointerventional units. Aneurysms were treated on(More)
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)
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 BBA is a rare type of intracranial aneurysm that is difficult to treat both surgically and endovascularly and is often associated with a high degree of morbidity/mortality. The aim of this study was to present clinical and angiographic results, as well as antiplatelet/anticoagulation regimens, of endovascular BBA treatment by using(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.
