Background and Objectives Groundbreaking trials have shown the tremendous efficacy of mechanical thrombectomy for large vessel occlusions. Currently, mechanical thrombectomy is limited to patients with NIHSS scores ≥6. We investigated the feasibility and safety of MT in patients presenting with NIHSS scores <6.
Objectives The pathogenesis of intracranial aneurysms is multifactorial and includes genetic, environmental, and anatomic influences. We aimed to identify image-based morphological parameters that were associated with middle cerebral artery (MCA) bifurcation aneurysms.
Objectives Elevated platelet distribution width (PDW) is a recognized marker of platelet activity. Herein, we investigated the association between admission PDW values and clinical outcome at 3 months in acute ischemic stroke (AIS) patients undergoing mechanical thrombectomy (MT).
Highlights • Foamy macrophages and thrombosis are significant predictors of symptomatic carotid artery stenosis. • Symptomatic plaques were significantly more frequently classified as AHA type VI than AHA type IV-V compared to asymptomatic ones. • A complex plaque structure (AHA type VI) is, rather than the single histological features, predictive of plaque instability.
Objectives Recent endovascular trials have established the use of CT perfusion (CTP) in endovascular treatment selection for patients with large vessel occlusions (LVO). However, the relationship between CTP and collateral circulation is unclear in delayed time windows. We explored the relationship between CT Angiogram (CTA) collaterals and CTP parameters in delayed time windows (6-24 hours).
Background Nonagenarians have been underrepresented in stroke trials that established endovascular treatment as the standard for acute ischemic stroke (AIS). Evidence remains inconclusive regarding the efficacy of thrombectomy in this population.
Objective Flow diversion is becoming an increasingly established practice for the treatment of acutely ruptured intracranial aneurysms. In this study the authors present a literature review and meta-analysis, adding a retrospective review of institutional registry on emergency treatment of aRIA with flow diverter stent.
Objectives To investigate if Red cell distribution width (RDW) can predict long-term prognosis in patients with acute ischemic stroke (AIS) receiving endovascular therapy (EVT).
Background and objectives Randomized trials for mechanical thrombectomy (MT) excluded patients with ischemic strokes due to isolated posterior cerebral artery occlusion (IPCAO), and there is no evidence for best acute treatment strategy in these patients. We aimed to assess the effectiveness and safety of MT in acute IPCAO.
Objectives Mechanical thrombectomy (MT) has become leading treatment option for acute ischemic stroke (AIS) due to large vessels occlusion (LVO). Platelet counts may affect outcome in patients with AIS or transient ischemic attack. The aim of our study was to determine the influence of thrombocytopenia on the safety and efficacy of MT in patients with AIS due to anterior circulation LVO.
Objectives To prospectively evaluate the clinical usefulness of Silent magnetic resonance angiography (Silent MRA) in the follow-up of endovascular-treated intracranial aneurysms by comparing it with time-of-flight magnetic resonance angiography (TOF MRA) and digital subtraction angiography (DSA).
Objectives The recommendations of international guidelines for the management of asymptomatic carotid stenosis (ACS) often vary considerably and extend from a conservative approach with risk factor modification and best medical treatment (BMT) alone, to a more aggressive approach with a carotid intervention plus BMT. The aim of the current multispecialty position statement is to reconcile the conflicting views on the topic.
Purpose: The angiographic visualization of the stent during mechanical thrombectomy (MT) may provide information regarding the characteristics of the underlying occluding clot, device-clot interaction, and recanalization. The purpose of this study was to evaluate the open stent sign in relation to the retrieved clot and recanalization.
Background Recently studies have shown that select acute ischemic stroke (AIS) patients with large ischemic core could be deemed as reasonable candidates to receive mechanical thrombectomy (MT) with low risk of developing parenchymal hemorrhage (PH) or symptomatic intracerebral hemorrhage (sICH); however, the selection criterion remains lacking. Our study aims to investigate the relationship between a novel imaging biomarker of largest core mass volume (LCMV) and development of PH in stroke patients with large ischemic core who have undergone MT.
Objectives Radial access is an increasingly popular approach for performing cerebral angiography. There are two sites for radial artery puncture: proximal transradial access (pTRA) in the wrist and distal transradial access (dTRA) in the snuffbox. These approaches have not been directly compared.
