Pilot Study of St George’s Vascular Institute Protocol for Comprehensive Assessment of Type B Aortic Dissection Morphology: A Reproducible Protocol for Clinical and Research Applications

Accurate 3-dimensional analysis of TBAD morphology can be reliably performed within a reasonable timeframe. Measurements based on consistent anatomical landmarks demonstrated the highest reproducibility. It is suggested that this protocol is adopted for clinical studies and trials on acute TBAD.Clinical ImpactThe morphological characteristics of the aorta play a pivotal role in guiding treatment strategies and prognosticating outcomes in patients with acute type B aortic dissection (TBAD). Despite its critical importance, there remains a lack of consensus regarding the optimal approach to the morphological assessment of TBAD. This study presents a standardized and internally validated protocol for the evaluation of aortic morphology. The proposed methodology is intended to facilitate both clinical decision-making and research endeavors in the context of acute TBAD.
