Type of internal carotid artery-posterior communicating artery circulation Based on the literature, variations in the posterior circulation of the circle of Willis were classified into two types 17.

Elk hunter Henry Rauschenbach’s near-death story is a gut-wrenching, inspiring account of wilderness survival.

Anatomy of the posterior circulation and important variants The posterior circulation is made up of the vertebral arteries, basilar artery, posterior cerebral arteries and their branches (figure 1).

A double overlapping reverse Y-stent approach to creating flow diversion using traditional open-cell stent technology was evaluated as a treatment option symptomatic fusiform basilar aneurysms. A ...

Background Endovascular therapy (EVT) dramatically improves clinical outcomes for patients with anterior circulation emergent large vessel occlusion (ELVO) strokes. With recent publication of two ...

Cross‐sectional imaging revealed occlusion of the basilar artery with a persistent primitive proatlantal artery. She then underwent successful mechanical thrombectomy. Complete reperfusion was ...

The effects and risks of endovascular thrombectomy 6 to 24 hours after stroke onset due to basilar-artery occlusion have not been extensively studied.

Patient recovered with a 3-month mRS of 1. Occlusion length was dichotomized to either “long,” consisting of two or more basilar artery segments (proximal, middle, and distal), or “short,” consisting ...

While in most individuals both vertebral arteries connect to form the basilar artery, originating the PICA on their V4 segments, in this case such segment is hypoplastic; the anastomosis (black arrow) ...

Methods: We examined a cohort of refractory patients with long-segmental occlusion in the VA and low flow in the basilar artery (BA). The hybrid technique was performed to achieve the recanalization ...
