Abstract

Two male patients who presented with altered mental states and hemiparesis were treated by retrieval thrombectomy. The occlusion sites were M1 in both patients. During each thrombectomy, a self-expanding and fully retrievable Solitaire stent was partially deployed to cover the whole intra-arterial clot and then was retrieved slowly while occluding the internal cerebral artery with a balloon-guiding catheter. Complete recanalization (defined as thrombolysis of cerebral infarction grade 2b or 3) was achieved in both patients. The procedural time from groin puncture to recanalization was 17 min and 30 min, respectively. Immediate post-operative National Institutes of Health Stroke scores improved to 17 from 22 in one patient and to 19 from 24 in the other patient. There were no procedure-related complications including distal embolisms or post-operative intracranial hemorrhages. We suggest that this technique may be a simple, rapid, and safe thrombolytic method for acute ischemic stroke patients with large artery occlusions.
