False Lumen Thrombosis and Pressure Predicts Outcome in Patients with Acute Type B Aortic Dissection

Abstract

Introduction: Owing to the uncertainty around how best to manage patients with type B aortic dissection (TBAD), improved risk stratification is a key priority. Partial false lumen thrombus morphology has been demonstrated to predict complications; however, partial thrombosis is poorly defined and has not been evaluated in detail. We hypothesised that partial false lumen thrombosis is a marker of false lumen pressure and that false lumen pressure is related to clinical events.
