E.2 Predictors of successful endovascular thrombectomy for M2 occlusion in acute ischemic stroke

Background: There remains lack of data in regards to factors influencing successful endovascular reperfusion isolated occlusion the M2 segment middle cerebral artery (MCA). In this study, we set out investigate variables that affect occlusion. Methods: was defined as clot anywhere within MCA. A prediction model modified Thrombolysis Cerebral Ischemia (mTICI) score 2b, 2c and 3 unsuccessful mTICI 0, 1 2a developed from demographics (age, sex) , clinical (NIHSS at time presentation hospital), imaging characteristics (ASPECTS, ICA occlusion, presence Intracranial arterial disease (ICAD), computed tomography perfusion (CTP)-based ischemic core mismatch volume estimation), treatment (alteplase/tenecteplase use periprocedural complications) 64 patients who underwent thrombectomy (EVT) Kingston Health Science Centre between December 24, 2018 October 18, 2022. Results: The only statistical significant predictor CTP-based (smaller volume) (p<0.05). Conclusions: is most important for
