Abstract:
Objective To evaluate the efficacy of endovascular stent-graft placement for the treatment of Debakey Ⅲ type aortic dissection. Methods From June 2001 to July 2006, 31 patients with Debakey Ⅲ type aortic dissection were diagnosed by contrast-enhanced CT scan. Vascular access was obtained through the right or left femoral artery after arteriotomy and stent-graft was deployed into the true lumen to occlude the primary entry tear. Immediate aortography was performed after the procedure and the follow-up data of CT scan were evaluated. Results Stent-graft deployment was successfully performed in all the patients. Immediate aortography after the procedure showed no leakage in 27 patients and minor leakage in 4. After the operation, one patient showed paraplegia, and one developed left arm ischemia. No stent movement or organ ischemia was found at the early postoperative stage in the other patients. Six months after the operation, in all the 31 patients, contrast-enhanced CT scan showed the disappearance of the false lumen and thrombosis at the level of the stent; and the minor leakage of was improved in the 4 patients. Four years after the operation, one patient developed severe internal leakage at the approximal end of the stent, and was treated by thoracotomy. Conclusions Endovascular stent-graft placement is effective for the treatment of Debakey Ⅲ type aortic dissection. However, further studies are needed to evaluate its long-term outcomes.
