BACKGROUND Pediatric intracranial aneurysms are rare and not well characterized in comparison with those in adults. OBJECTIVE To analyze our institution's longitudinal experience of endovascular treatment for pediatric aneurysms to better understand this rare condition. METHODS A retrospective record review was performed of patients aged <20 years(More)
BACKGROUND AND PURPOSE The GDC system is a valuable therapeutic alternative to surgical treatment of intracranial aneurysms. We present our clinical experience with the GDC technique used to treat unruptured cerebral aneurysms. METHODS This is a retrospective review of 217 patients with 247 unruptured intracranial aneurysms who underwent embolization with(More)
BACKGROUND AND PURPOSE Mechanical thrombectomy is a promising means of recanalizing acute cerebrovascular occlusions in certain situations. We sought to determine if increasing age adversely affects prognosis. MATERIALS AND METHODS We reviewed all Merci thrombectomy cases and compared patients younger than 80 years of age with older individuals. We(More)
BACKGROUND The influence of cerebral microbleeds (CMBs) on post-thrombolytic hemorrhagic transformation (HT) in patients with acute ischemic stroke remains controversial. OBJECTIVE To investigate the association of CMBs with HT and clinical outcomes among patients with large-vessel occlusion strokes treated with mechanical thrombectomy. METHODS We(More)
PURPOSE To characterize the relationship between aneurysm size and epidemiologic risk factors with growth and rupture by using computed tomographic (CT) angiography. MATERIALS AND METHODS In this HIPAA-compliant, institutional review board approved study, patients with known asymptomatic unruptured intracerebral aneurysms were followed up longitudinally(More)
OBJECT A new embolic agent, bioabsorbable polymeric material (BPM), was incorporated into Guglielmi detachable coils (GDCs) to improve long-term anatomical results in the endovascular treatment of intracranial aneurysms. The authors investigated whether BPM-mounted GDCs (BPM/GDCs) accelerated the histopathological transformation of unorganized blood clot(More)
BACKGROUND AND PURPOSE The purpose of this study was to determine whether leukoaraiosis (LA) predicts hemorrhagic transformation and poor outcome in patients with acute ischemic stroke treated by mechanical thrombectomy. METHODS We retrospectively analyzed patients with anterior circulation stroke treated with Merci devices and identified LA in the deep(More)
OBJECTIVE Giant intracranial aneurysms present unique therapeutic intricacies. The purpose of this study was to evaluate the anatomic and hemodynamic characteristics of these lesions and the current endovascular and combined surgical and endovascular techniques available for their treatment. METHODS A review of the literature and the personal experiences(More)
BACKGROUND AND PURPOSE Use of the Merci retriever is increasing as a means to reopen large intracranial arterial occlusions. We sought to determine whether there is an optimum number of retrieval attempts that yields the highest recanalization rates and after which the probability of success decreases. MATERIALS AND METHODS All consecutive patients(More)
OBJECTIVE Because of their anatomic configuration, middle cerebral artery (MCA) aneurysms are most often treated with surgical clipping. However, endovascular coil embolization of these aneurysms is an increasingly used alternative. We retrospectively reviewed the anatomic and clinical outcomes of patients with MCA aneurysms who underwent endovascular(More)
