Early and Mid-Term Outcomes Following TEVAR for Chronic Type B Aortic Dissection

: We examined the outcomes of aortic remodeling for chronic type B aortic dissection (cTBD) after thoracic endovascular aneurysm repair (TEVAR). Objective & Methods: Thirty-eight patients underwent TEVAR for cTBD at our institution. We classified cTBD patients into the early cTBD group (16 cases, 2 weeks-4 months from onset) and late cTBD group (22 cases, >4 months from onset). Results: There were no cases of paraplegia, stroke, and hospital death in both groups. There was no worsening of complicated cases. We achieved false lumen thrombosis in cases with a double-barreled thoracic aorta. The early cTBD group had more complete shrinkage cases (60%) than the late cTBD group (11%). Conclusion: We obtained favorable mid-term outcomes after TEVAR for cTBD patients. Early cTBD patients obtained good aortic remodeling with TEVAR.
