Abstract 051: Utilization of CT Perfusion to Optimize Selection Of Elderly Patients For Thrombectomy: A Retrospective analysis

Abstract

Introduction CT perfusion (CTP) has been utilized to appropriately select patients with large vessel occlusion (LVO) for endovascular thrombectomy (EVT). Elderly patients and patients with fast‐growing ischemic cores have been shown to have worse outcomes after EVT. There is limited data on elderly patients aged ≥90 years old and ischemic core growth related to outcomes. We aimed to examine age, ischemic core growth, and outcomes in patients with LVO treated with EVT [1]. Methods This is a retrospective study using prospectively collected data from a large academic medical center. Patients with LVO and treated with EVT between December 2017 and December 2022 were included in this study. Patients without CTP completed prior to EVT, patients with missing baseline or 90‐day modified Rankin Scale scores (mRS), and patients in which CTP was completed but failed were excluded from this study. Early infarct growth rate (relative cerebral blood flow 0.38. Conclusion Excellent reperfusion rates were not affected by age or ischemic core growth rate. Despite this, elderly patients with fast ischemic core growth were more likely to experience worse 90 day functional outcomes compared to younger patients and patients with slower core growth prior to EVT.
