Late Window Imaging Selection for Endovascular Therapy of Large Vessel Occlusion Stroke: An International Survey

Abstract

Current guidelines for imaging late window EVT candidates are inconsistent with imaging decisions by physicians. Most respondents consider an imaging delay of greater than 20 minutes unacceptable. Access to advanced imaging was greater in comprehensive stroke centers and high-income countries. In the case of limited access most respondents would consider EVT based on CT only.
