To evaluate the security and effectiveness of endovascular repair (EVAR) of complicated Stanford B acute aortic dissection (AAD).
Retrospectively analysis clinical characteristics, perioperative characteristics and effectiveness of complicated Stanford B AAD patients treated with EVAR from April 2002 to February 2016.
1.Perioperative: 99 patients underwent EVAR treatment, 99.0% (98/99) operations were successful, 104 stents were implanted, the proximal average diameter was (38.9±3.3) mm, the mean length was (145.8±26.5) mm. 7 patients (7.1%) were combined coronary intervention. 7 patients died in hospital (7.1%), including 1 patient died from aortic dissection ruptured during surgery, 5 patients died from aortic dissection ruptured after surgery and 1 patients died from multiple organ failure. 2.Follow-up: The median follow-up time was 24 months. 9 patients (11.7%) died, including 4 cases cardiac death (5.2%). 1 cases recurrent dissection treated with EVAR (1.3%).
Perioperative and follow-up results showed that EVAR treatment is safe and effective for complicated Stanford B AAD.
