Rapid prediction of hemorrhagic transformation after endovascular thrombectomy: a multimodal model in patients with post-thrombectomy cerebral hyperdensities
Clinical Report: Swift Assessment of Hemorrhagic Transformation Risk Following EVT
Overview
This study presents a novel multimodal deep learning framework for predicting hemorrhagic transformation (HT) in patients post-endovascular thrombectomy (EVT). The model demonstrated superior predictive performance compared to human neuroradiologists.
Background
Hemorrhagic transformation is a significant complication following EVT for acute ischemic stroke, often leading to poorer functional outcomes. Early identification of patients at high risk for HT is crucial for effective neuromonitoring and management. Current imaging techniques can be time-consuming and may not provide timely risk assessments, necessitating the development of rapid predictive tools.
