Imaging Selection and Outcomes of Thrombectomy for Acute Stroke

CT and CTP fared similarly in identifying good thrombectomy candidates; unfavorable CTP findings might indicate increased risk for adverse events.

Endovascular thrombectomy (EVT) improves stroke outcomes for select patients when performed within 24 hours after ischemic stroke onset. Imaging practices to determine EVT eligibility vary among hospitals: Some use brain CT and the Alberta Stroke Program Early CT Score (ASPECTS) to judge extent of infarction. Others use CT perfusion (CTP) to identify a “favorable profile” of small infarct core and medium/large hypoperfused area. To expand on the limited data on outcomes when these imaging methods are discordant versus concordant, researchers conducted a multicenter, observational trial to assess EVT outcomes in patients with acute stroke. A core imaging lab reviewed acute radiology results to determine if the CT was favorable (ASPECTS score…
