Prolonged Venous Transit as a Superior Predictor of Functional Outcomes in Successfully Reperfused Large Vessel Occlusions: Comparative Analysis With Cerebral Blood Volume Index and Hypoperfusion Intensity Ratio

Prolonged Venous Transit as a Superior Predictor of Functional Outcomes in Successfully Reperfused Large Vessel Occlusions: Comparative Analysis With Cerebral Blood Volume Index and Hypoperfusion Intensity Ratio

Background Collateral status plays a crucial role in outcomes after acute ischemic stroke due to large vessel occlusion. Tissue‐level collaterals and venous outflow are key components following mechanical thrombectomy. This study evaluates the predictive performance of prolonged venous transit (PVT)...
