Intracranial venous stenting for idiopathic intracranial hypertension.

Introduction: There is increasing evidence in the literature to support venous sinus stenting in patients with idiopathic intracranial hypertension who fail first-line therapy. Venous sinus stenting is a safe and successful technique compared with cerebrospinal fluid diversion procedures. This study examines the clinical outcomes of patients post intracranial venous stenting for intracranial hypertension across three tertiary hospitals in Western Australia.

Ultra-Long Transfers for Endovascular Thrombectomy-Mission Impossible?: The Australia-New Zealand Experience.

Background: Endovascular thrombectomy (EVT) access in remote areas is limited. Preliminary data suggest that long distance transfers for EVT may be beneficial; however, the magnitude and best imaging strategy at the referring center remains uncertain. We hypothesized that patients transferred >300 miles would benefit from EVT, achieving rates of functional independence (modified Rankin Scale [mRS] score of 0-2) at 3 months similar to those patients treated at the comprehensive stroke center in the randomized EVT extended window trials and that the selection of patients with computed tomography perfusion (CTP) at the referring site would be associated with ordinal shift toward better outcomes on the mRS.

Upper extremity transvenous access for neuroendovascular procedures: an international multicenter case series.

Background: Radial artery access for transarterial procedures has gained recent traction in neurointerventional due to decreased patient morbidity, technical feasibility, and improved patient satisfaction. Upper extremity transvenous access (UETV) has recently emerged as an alternative strategy for the neurointerventionalist, but data are limited. Our objective was to quantify the use of UETV access in neurointerventions and to measure failure and complication rates.

Transradial versus transfemoral access for anterior circulation mechanical thrombectomy: analysis of 375 consecutive cases.

Objective: To compare transradial artery access (TRA) to the gold standard of transfemoral artery access (TFA) in mechanical thrombectomy (MT) for stroke caused by anterior circulation large vessel occlusion.

Methods: The clinical outcomes, procedural speed, angiographic efficacy and safety of both techniques were analysed in 375 consecutive cases over an 18-month period in a high volume statewide neurointerventional service.

Results: There was no significant difference in patient characteristics, stroke parameters, imaging techniques or intracranial techniques.

Transradial intracranial aneurysm treatment via an aberrant right subclavian artery.

We report two cases of successfully treated intracranial saccular aneurysms via transradial access with aberrant right subclavian artery anatomy. Two patients aged 74 and 82 years with anterior communicating artery aneurysms deemed suitable for endovascular treatment and anomalous aortic arch anatomy (aberrant right subclavian artery) underwent successful treatment with transradial access. Transradial access was obtained in both patients, in the first patient, without prior knowledge of the aortic arch anatomy.

First line transradial access for posterior circulation stroke intervention; initial 12-month experience at a high volume thrombectomy center.

Background: The Neurointerventional Surgery Standards and Guidelines Committee has advocated the use of transradial access in the setting of posterior circulation stroke intervention, however there is a paucity of published data on this approach. The purpose of this study is to present 12-months of prospectively collected data from a high volume thrombectomy center following the adoption of a first line transradial approach for posterior circulation stroke intervention.

Methods: A range of data on patient characteristics, procedural metrics, complications and outcomes was prospectively collected between August 2018 - August 2019 following the adoption of first line transradial access for posterior circulation stroke intervention at a high volume thrombectomy center.

Revisiting the surface anatomy of the sciatic nerve in the gluteal region in children using computed tomography.

No anatomy text specifically describes the course of the sciatic nerve (SN) in the gluteal region in children. Anatomical information is largely derived from cadaveric studies of adults, so accurate anatomical information about the location of the SN in children is required. The aim of this study is to assess the surface anatomy of the SN in children using computed tomography (CT).
