Systematic Review of Reintervention After Thoracic Endovascular Repair for Chronic Type B Dissection

This review analyzed the incidence, mechanisms, and risk factors of aortic-related reintervention after endovascular repair of chronic dissections. The systematic review identified 28 studies describing 1,249 patients at median 27 months follow-up (range, 10.3 to 64.4). There were six reinterventions, 0.7 ruptures, and 1.2 surgical conversions per 100 patient-years of follow-up. Stent-related reinterventions were more frequent than nonstent related (80.2% vs 19.8%). Distal false lumen perfusion was the most common complication (40.5%). No individual risk factor-treatment timing, disease extent, covered aorta length, or remodelling-was associated with reintervention. Further investigation based on consistent reporting standards is required.
