Objective To assess the results of emergency endovascular stent-grafting for patients with acute Stanford type B aortic dissection(type B AAD)within 24 hours of onset.Methods Between June 2007 and October 2008,30 patients with acute type B aortic dissection underwent emergency endOVascular stent-grafting within 24 hours of presentation.Under general anesthesia,stent-graft was deploved at the proper position of first tear entry through femoral artery under X-ray monitering.Follow-up by CT was performed 1 w,1 m ,3 m,6 m,1 y postoperatively to observe the efficacy and complications such as endoleak,migration and fracture of stent-graft. Result The technical success rate was 100%;13.4%(4 cases) endoleak rate was identified immediately after deployment.Follow up was made between 1 month to 19 months,averaging at(12±8)months,3.3%type-1 endoleak Was observed after 6 months;One patient died within 30 days possibly of dissection rupture;One patient died of acute liver failure during the follow-up. Conclusion Endovascular repair with stent-graft within 24 hours of presentation was effectivefor the treatment of acute type B aortic dissection.
