Abstract Background and Purpose— Multiple randomized clinical trials have demonstrated the superiority of endovascular therapy (ET) for large vessel occlusion acute ischemic stroke (AIS). Few centers can provide ET, and significant debate exists about the most efficient and effective ways to provide ET. We sought to assess real-world utilization of ET, the extent to which patients are transferred from one hospital to another for therapy and the implications of transfer status on outcomes.
Abstract Background and Purpose— After large-vessel intracranial occlusion, the fate of the ischemic penumbra, and ultimately final infarct volume, largely depends on tissue perfusion. In this study, we evaluated whether blood pressure reduction and sustained relative hypotension during endovascular thrombectomy are associated with infarct progression and functional outcome.
Abstract Background and Purpose— Endovascular therapy has been shown to be highly efficacious based on 90-day modified Rankin Scale score. We examined actual daily healthcare utilization from stroke onset to 1 year afterward from the ESCAPE trial (Endovascular Treatment for Small Core and Anterior Circulation Proximal Occlusion With Emphasis on Minimizing CT to Recanalization Time) and registry data.
Abstract Background and Purpose— Unruptured intracranial aneurysms (UIAs) have various scenarios of growth and rupture. Magnetic resonance vessel wall imaging can detect aneurysmal wall thickening with inflammation and neovascularization. This study was performed to explore the vessel wall imaging findings of UIAs with consecutive follow-up
Abstract Background and Purpose— Novel double layer micromesh stents have recently been introduced for treatment of patients with significant carotid stenosis. Strict evaluation of safety and patency of such novel devices is required both in elective and in emergency interventions. We report a single center experience with double layer mesh stents for carotid artery revascularization.
Abstract Background and Purpose— The purpose of this study was to evaluate trends in length of stay, discharge status, and costs among patients with acute ischemic stroke who underwent endovascular therapy (ET) between 2011 and 2017.
Background and Purpose— We analyzed the relationship between HbA1c (glycated hemoglobin) levels and clinical outcomes in patients with large vessel occlusion treated with mechanical thrombectomy (MT).
Background and Purpose— Carotid artery stenting in tandem large vessel occlusion strokes is usually avoided because of the intracranial hemorrhagic risks induced by antiplatelet therapy during thrombectomy interventions. This study aimed to evaluate the incidence of hemorrhagic transformation following thrombectomy in large vessel occlusion strokes patients with atherosclerotic cervical carotid occlusion, associated factors, and clinical relevance.
Background and Purpose— Our goal was to evaluate whether the presence of a low signal intensity known as susceptibility vessel sign (SVS) on T2*-gradient echo imaging sequence was predictive of arterial recanalization and the early clinical improvement after mechanical thrombectomy.
Background and Purpose— The safety and efficacy of mechanical thrombectomy in patients with acute ischemic stroke has been demonstrated. However, the impact of stent retriever size on clinical and angiographic outcomes is not well established.
Background and Purpose— Although intracranial thrombectomy represents the standard treatment approach for anterior circulation tandem occlusions, whether the extracranial lesion requires acute stenting remains unclear. Our aim was to investigate differences in clinical and procedural outcomes related to stenting extracranial lesions in a registry of patients undergoing thrombectomy for acute stroke.
Background and Purpose— It is unclear whether endovascular treatment (EVT) is beneficial for patients with acute ischemic stroke with occlusion of the M2 segment of the middle cerebral artery. We aimed to compare functional outcomes, technical aspects, and complications of EVT between patients with acute ischemic stroke because of M2 and M1 occlusions in clinical practice. Furthermore, outcome and complications after EVT in dominant and nondominant caliber M2 division occlusions were studied.
Background and Purpose— We investigated whether procedural stroke or death risk of carotid artery stenting (CAS) compared with carotid endarterectomy (CEA) is different in patients with and without history of coronary heart disease (CHD) and whether the treatment-specific impact of age differs.
Background and Purpose— Factors influencing recanalization success in basilar artery occlusions are largely unknown. Preliminary evidence has suggested that flow arrest in the vertebral artery contralateral to the catheter bearing vertebral artery may facilitate recanalization. The aim of this analysis was to assess the impact of anatomic variations and flow conditions on recanalization success in basilar artery occlusion treated with mechanical thrombectomy.
Background and Purpose— Randomized trials comparing the use of multimodal magnetic resonance imaging (MRI) to multimodal computed tomography (CT)/ CT angiography (CTA) for selecting candidates for endovascular therapy (EVT) have not been reported. This study aimed to elucidate whether MRI-based selection for EVT is safe and effective within and after a 6-hour time window compared with conventional CTA-based selection.
