This study evaluated anatomical variants in the carotid siphon and of the circle of Willis in patients with aneurysms. We performed a retrospective analysis of cerebral angiographies. The Control ...

I could see the artery and could tell that it was cut entirely in two. In a moment of panic, I started running. My mind told me I needed to get back to camp as fast as possible. My adrenaline was in ...

Figure 1 Posterior circulation vessels. The drawing shows the four segments (V1–V4) of the vertebral arteries from their origins at the subclavian arteries. They give off the posterior inferior ...

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 ...

Basilar artery occlusion (BAO) accounts for approximately 1% of all ischemic strokes and about 10% of strokes due to an intracranial large vessel occlusion. 4 Although this condition may be relatively ...

The term proatlantal intersegmental artery was first used by Padget after a detailed discussion of the discrepancies of the nomenclature in the embryonic arteries. 2, 3 These anatomic embryological ...

Patients were eligible for inclusion in the trial if they were 18 to 80 years of age; had an occlusion of the basilar artery or intracranial segments of both vertebral arteries that could be ...

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 ...

Figure 2. Illustrative drawings depict the standard posterior circulation anatomical disposition (A), in right posterior oblique view, and the patient’s variant (B), in posterior view. While in most ...

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 ...
