Poor Cortical Venous Opacification on Baseline Computed Tomography Angiography Predicts Parenchymal Hemorrhage After Thrombectomy.

ABSTRACT:

Background

Although the association between cortical venous opacification (VO) and clinical outcomes has been shown in previous studies, little is known about the relationship between parenchymal hemorrhage (PH) and VO in patients with acute stroke. We aimed to determine whether cortical VO assessed on computed tomography angiography correlates with the risk of PH following endovascular treatment.

Methods

This is a post hoc analysis of the ESCAPE NA-1 (Efficacy and Safety of Nerinetide in Subjects Undergoing Endovascular Thrombectomy for Stroke) trial. Control-arm patients with adequate venous assessment on computed tomography angiography were included. Any PH and symptomatic intracranial hemorrhage were compared between patients with poor VO (cortical vein opacification sco
