This is the first in a set of documents intended to standardize techniques, procedures, and practices in the field of endovascular surgical neuroradiology. Standards are meant to define core practices ...

Introduction The advent of metal flow-diverting stents has provided neurointerventionalists with an option for treating aneurysms without requiring manipulations within the aneurysm sac. The large ...

Objective Intracranial venous sinus stenosis (IVSS) is the most common finding associated with idiopathic intracranial hypertension. A pressure gradient >8–10 mm Hg across the stenosis is considered ...

Objective The efficacy of intra-arterial vasodilators (IADs) for the treatment of vasospasm following aneurysmal subarachnoid hemorrhage (aSAH) remains debatable. The objective of this meta-analysis ...

Background The purpose of this review is to summarize the data available for the role of angiography and embolization in the comprehensive multidisciplinary management of brain arteriovenous ...

Background and purpose In-stent restenosis (ISR) is one of the long-term adverse outcomes of endovascular angioplasty and stenting for symptomatic intracranial arterial stenosis. In this study, we try ...

Background Venous sinus stenting (VSS) has been shown to reduce intracranial venous pressures and improve symptoms in patients with idiopathic intracranial hypertension (IIH). However, long-term ...

Background Direct aspiration thrombectomy is a well-established method for mechanical thrombectomy in acute ischemic stroke. Yet, the influence of aspiration catheter internal diameter (ID) on ...

Background Studies over the past decade have demonstrated that clopidogrel hyper-response (P2Y12 Platelet Reaction Unit, PRU < 40) in cerebral aneurysm flow diverter (FD) cases is associated with ...

Intracerebral hemorrhage (ICH) is a devastating disease with high morbidity and mortality.1 In principle, the surgical removal of ICH should benefit the patient by removing the source of the primary ...

Background Flow diverters have revolutionized the treatment of intracranial aneurysms. However, the delayed complications associated with flow diverter use are unknown. Objective To evaluate the ...

Background A direct aspiration first pass technique (ADAPT) is an efficient, safe, cost-effective, and fast thrombectomy technique. Objective To evaluate anatomical and clot characteristics associated ...
