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. (This is a translation of Jpn J Vasc Surg 2016; 25: 233-239.).
