Aims The objective of this systematic review is to determine with the highest accuracy the average radial artery (RA) diameter overall and in certain subgroups. The aim of this study is to provide ...

Background and purpose Collateral blood flow to the affected cerebral territory in acute ischemic stroke may modify the effect of intravenous alteplase treatment (IVT) prior to endovascular treatment ...

Background The first-pass effect (FPE) is linked to better safety and efficacy prognosis in patients with small- to- moderate sized ischemic infarctions. We evaluated the incidence, prognosis, and ...

Neurovascular catheter technology has rapidly evolved over the past decade. While performance characteristics are well known to the practitioner, the design features of these new-generation catheters ...

Large vessel occlusion causing acute ischemic stroke is ideally treated with endovascular clot retrieval, which is increasingly being performed via direct aspiration thrombectomy. Successful ...

Background Higher positioning of a large bore guide catheter during endovascular thrombectomy (EVT) is hypothesized to potentially improve thrombectomy success. Objective To evaluate the safety and ...

Treatment of wide-necked complex intracranial aneurysms continues to challenge neurointerventionalists. Intrasaccular flow diverters have expanded the armamentarium considerably and are now used ...

AVM angioarchitecture Risk stratification of AVM rupture has been mainly based on the presence of certain radiologic parameters and AVM angioarchitecture features. The location of the AVM has been ...

Objective Fractional flow (FF) reserve has been developed as a gold standard for coronary intervention. Intracranial FF is also a valuable hemodynamic index to assess the severity of narrowing in ...

Background Hyperintense acute reperfusion marker (HARM) refers to delayed enhancement in the subarachnoid or subpial space on post-contrast fluid attenuated inversion recovery (FLAIR) images. HARM is ...

In recent years, venous sinus stenting (VSS) has emerged as an effective surgical treatment for idiopathic intracranial hypertension (IIH) with concomitant venous sinus stenosis. Meta-analyses of ...
