Abstract

Purpose While mechanical thrombectomy was known to be an effective revascularization tool for acute ischemic stroke, the five major clinical trials demonstrated that mechanical thrombectomy for large vessel Page 149 occlusions has impacted and improved clinical outcomes. However outcomes for isolated M2 occlusions have yet to be delineated. Our purpose is to add to available evidence that mechanical thrombectomy for M2 branch occlusions has clinical benefit. Materials and Methods Retrospective analysis of data set for patients at our single institution who underwent mechanical thrombectomy between January 2010 and August 2018. All patients to meet our inclusion criteria, which include: isolated M2 branch occlusion, comprehensive imaging evaluation (non-enhanced CT, CTAngiography and CT-Perfusion), and underwent mechanical thrombectomy. Results Included patients will meet our inclusion criteria. Collected data to include patient demographics, right or left-sidedness, co-morbidities, National Institute of Health (NIH) stroke scale scores, radiologic findings (ischemic penumbra), symptom onset to canalization time, procedure time, thrombectomy device used, Thrombolysis in Cerebral Infarction Scale (TICI) scores, follow-up of modified Rankin Scale (mRS) scores and complications. Conclusions Lack of randomized control trials (RCTs) for isolated M2 branch occlusions adds relevance to the importance of retrospective analysis of outcomes in mechanical thrombectomy for M2 branch occlusions. This data set can be compared with similar studies to depict the positive radiologic and clinical outcomes of mechanical thrombectomy for isolated M2 branch occlusions.
