Propensity Adjusted Analysis of Open and Endovascular Thoracic Aortic Repair for Chronic Type B Dissection: A Twenty-Year Evaluation

This analysis compared results of open repair for chronic Type B dissection (OAR) and endovascular repair (TEVAR) using propensity matching techniques.  Freedom from rupture/reintervention at 10 years was 78%.  Specific outcomes were similar for both types of intervention, but overall treatment efficacy was better for OAR.
