ObjectiveTo analyse the early and mid-term outcomes of endovascular repair of Stanford type B aortic dissection (B-AD) and to compare the outcomes between acute type B aortic dissection (AAD) and chronic type B aortic dissection (CAD).MethodsThe cohort included 121 consecutive patients undergoing endovascular repair for AAD (group A, n = 72) and CAD (group B, n = 49) between January 2001 and December 2006. Follow-up with clinical examinations and computed tomography (CT) was performed post-intervention at 1, 6 and 12 months, and then yearly thereafter.ResultsIn groups A and B, respectively, the procedure success rates were 88.9% and 77.6%; the rates of postoperative endoleak were 11.1% and 22.4%; the 30-day mortality rates were 1.4% and 8.2%; and the 30-day stroke rates were 4.2% and 2.0%. No postoperative spinal cord ischaemia (SCI) was observed. The mean follow-up periods for groups A and B were 14.4 ± 11.0 months and 22.1 ± 20.8 months, respectively. Late mortality was 1.5% in group A and 4.8% in group B. In group A, the rates of complete false lumen (FL) thrombosis at 1 month, 1 year and 2 years postoperatively were 32.3%, 51.4% and 53.8%, respectively, and in group B, 26.2%, 44.8%, and 50.0%, respectively.ConclusionEndovascular repair is feasible for both AAD and CAD, with favourable short- and mid-term outcomes.
