The South Texas population is well-acquainted with hypertension, Diabetes Mellitus Type 2 (DM2), and hyperlipidemia, all well-known risk factors for stroke1. Both anterior and posterior circulation strokes can lead to detrimental life changes, and although posterior circulation, or vertebrobasilar, strokes make up about 20% of all ischemic strokes2, their elusive characteristics often overlap with anterior circulation symptoms. In this study, we study factors that may influence the outcome of patients with posterior circulation stroke (PCS) following successful recanalization using mechanical thrombectomy. In this paper, the clinical outcome is evaluated by the primary endpoint, Modified Rankin Scale (mRS) at discharge. The outcomes (mild, moderate, severe) refer to the degree of severity of clinical impact. The current evidence that is available points towards a general poorer prognosis for recanalization of PCS than anterior circulation strokes (ACS)3. This paper seeks to investigate both patient related factors and treatment related factors that may influence the outcomes of cases PCS following mechanical thrombectomy and offers future direction that can improve our understanding of PCS.
