In 2010, a grant proposal to evaluate the best approach for managing patients with high-grade primary carotid atherosclerotic stenosis was first submitted for funding to the National Institute of Neurological Disorders and Stroke (NINDS) of the National Institutes of Health (NIH). In this conception, CREST-2 was to be a single randomized trial with two treatment arms: best revascularization (either carotid endarterectomy [CEA] or carotid artery stenting [CAS]) and intensive medical management versus intensive medical management alone.
Background and Purpose—Multimodal recanalization therapy in patients with acute basilar artery occlusion provides high recanalization rates. A substantial subset of treated patients survives with only minor or moderate functional handicap. However, long-term functional outcome and quality of life in these patients have rarely been systematically analyzed.
BACKGROUND: Stent-assisted coiling with 2 stents in a Y configuration is a technique for coiling complex wide-neck bifurcation aneurysms.
BACKGROUND AND PURPOSE: The mismatch between lesions identified in perfusion- and diffusion-weighted MR imaging is typically used to identify tissue at risk of infarction in acute stroke. The purpose of this study was to analyze the variability of mismatch volumes resulting from different time-to-peak or time-to-maximum estimation techniques used for hypoperfused tissue definition.
BACKGROUND AND PURPOSE: The initial angiographic occlusion rate is the strongest predictor of later rebleeding in previously ruptured coil-embolized cerebral aneurysms. Angiographic estimations of aneurysmal occlusion rates are, however, subjective in nature and confounded by methodologic problems. COR has been developed, and its superiority has been experimentally established to overcome subjective bias. The purpose of this study was to assess the clinical value of COR as a more objective predictor of aneurysm rebleeding when compared with SOR as described in the Raymond Classification.
We are the first to report a case that showed spontaneous resolution of epidural hematoma which was related to a steroid-induced osteoporotic compression fracture. The patient had a painful fracture with an intravertebral cleft at L1 accompanying an epidural hematoma posteriorly. Immediate pain relief was achieved after percutaneous vertebroplasty. Complete resolution of hematoma was noted three months after procedure. We theorized that intravertebral stability after treatment might have played a role in this patient.
Background and Purpose—Strokes secondary to acute internal carotid artery (ICA) occlusion are associated with extremely poor prognosis. The best treatment approach to acute stroke in this setting is unknown. We sought to determine clinical outcomes in patients with acute ischemic stroke attributable to ICA occlusion treated with intravenous (IV) systemic thrombolysis or intra-arterial endovascular therapy.
BACKGROUND: Recent studies from selected centers have shown that early surgical treatment of aneurysms in subarachnoid hemorrhage (SAH) patients can improve outcomes. These results have not been validated in clinical practice at large.
Background and Purpose—Flow diversion has emerged as an important tool for the management of intracranial aneurysms. The purpose of this study was to compare flow diversion and traditional embolization strategies in terms of safety, efficacy, and clinical outcomes in patients with unruptured, large saccular aneurysms (≥10 mm).
BACKGROUND: Stereotactic radiosurgery (SRS) of benign intracranial meningiomas is an accepted management option for well-selected patients.
BACKGROUND AND PURPOSE: In asymptomatic or remote symptomatic LAICOD, the risk of ischemic events is low in general, but there may be a subgroup of higher risk patients who require aggressive medical management. The purpose of this study was to determine whether chronic hemodynamic compromise is a predictor of ischemic events in asymptomatic or remote symptomatic LAICOD.
BACKGROUND AND PURPOSE: Abciximab and tirofiban are commonly used for the treatment of thromboembolisms that form during coiling of intracranial aneurysms; however, it is not known which of these inhibitors is safer and more effective. We report the safety and the recanalization rates for intra-arterial abciximab and intra-arterial tirofiban infusion for the treatment of thromboembolisms that form during coiling.
Background and Purpose Data from randomized trials assert that asymptomatic patients undergoing carotid endarterectomy (CEA) must live 3 to 5 years to realize the benefit of surgery. We examined how commonly CEA is performed among asymptomatic patients with limited life expectancy.
BACKGROUND AND PURPOSE: There are limited studies on the morphologic characteristics of MCA atherosclerotic stenosis. Our aim was to quantitatively assess the remodeling pattern and plaque distribution of atherosclerotic MCAs with 3T high-resolution MR imaging.
BACKGROUND AND PURPOSE: Given the challenges posed by surgical clipping, endovascular techniques have been increasingly used to treat SHA aneurysms. The purpose of this study was to assess the safety and efficacy of endovascular techniques in the treatment of SHA aneurysms.
