Objective:
To study the techniques and therapeutic effects of endovascular stent-graft exclusion in aortic dissection and dissecting aneurysm.
Methods:
The clinical data of 20 cases with aortic dissection and(or) dissecting aneurysm were analysed. Stanford A dissection was found in 2 cases, in which one had a tear entry on ascending aorta. Stanford B dissection was found in 18 cases. Five patients had two or more tear entries in different sites. Endovascular polyester-covered stent-graft exclusion was performed in all cases, of which, one case was also given fenestration and graft replacement and one subjected to Y graft bypass from ascending aorta to the left common carotid artery and left subclavian artery before endovascular stent-graft exclusion.
Results:
No one died in operation. One patient died of heart infarction on the third day after operation. During the followup of 1 - 20 months, 19 patients were alive well (95%). The aortic dissections and(or) dissecting aneurysms of all the patients disappeared without endoleaks and organ or limb ischemia.
Conclusion:
Endovascular stent-graft exclusion with high successful rate, low mortality and high survival rate, is simple, safe and effective in treating aortic dissection and dissecting aneurysm.
