Permanent Deployment of the Solitaire FR™ Device in the Basilar Artery in an Acute Stroke Scenario.

Abstract

Background: Scarce reports exist of permanent deployment of Solitaire FR™ devices for arterial steno-occlusive disease as it is primarily indicated for temporary deployment for thrombectomy in large-vessel, anterior-circulation ischemic strokes. Even more scarce are reports describing permanent deployment of the Solitaire device for posterior circulation strokes.

Summary: We present 2 cases where the Solitaire device was electrolytically detached to re-establish flow in an occluded or stenotic basilar artery in acutely symptomatic patients. In both cases, a 4 × 15 mm Solitaire device was positioned across the stenotic or occluded portion of the basilar artery and electrolytically detached to maintain vessel patency. Both cases had good clinical outcomes with a National Institutes of Health Stroke Scale (NIHSS) score of 1 (from 24) on 90-day follow-up and an NIHSS score of 2 (from 7) on 30-day follow-up.

Key messages: Permanent deployment of the Solitaire device may potentially be a safe and effective means of maintaining vessel patency in an occluded or stenotic basilar artery.
