Abstract TP7: Isolated Basal Ganglia Strokes Undergoing Thrombectomy Have High Rates of Good Clinical Outcomes

Background and Purpose: Isolated basal ganglia strokes are thought to have worse clinical outcomes as compared to mixed and cortical infarcts. Methods: Review of a prospectively collected database of endovascular patients with anterior circulation Large vessel occlusion strokes from January 2014-June 2018. Only patients with an ASPECT score of 6 to 9 were included. Patients were dichotomized into 2 groups according to ASPECT region involvement: (i) isolated basal ganglia and (iBG) (ii) other stroke patterns. Baseline characteristics and Clinical outcomes were compared. Results: 465 patients qualified for the study of which 324 (70%) were iBG strokes. Baseline characteristics were comparable between the 2 groups except for higher rates of hypertension (73.8%vs63.8%,p=0.03) and larger CTP core infarct (3.6 cc[0-13] vs 3[0-10.85], p Conclusions: iBG strokes carry similar procedural and clinical outcomes as other stroke patterns with a trend towards lower mortality.
