Abstract:
Objective To summarize our clinical experience and results of Stanford type B dissection,and analyzed the risk factors of reoperation.Methods From February 2009 to December 2011,81 patients (54 male and 27 female) of Stanford type B aortic dissection underwent surgical procedure in Beijing Anzhen Hospital The mean age was 19 -77 years,averaged (41.6±11.7)years.Associated with hypeftension in 48 cases,Marfan syndrome in 15 case,aortic root aneurysm in 7cases,dilation of aortic sinus and ascending aorta each in one,coarctation of the aorta in 1 case.Reoperation was done in 22cases and 4 of 22 needed the third operation.The risk factors of reoperation were analyzed with Logistic regression analysis.Results Sun (s) procedure was operated on 16 cases,concomitant procedures included Bentall in 7 cases,David in 1,replacement of the ascending aorta in 2 cases,CABG in 1 case.The thoracoabdominal aortic replacement in 31 cases,the descending thoracic aortic replacement in 9 cases,the stented elephant trunk procedure in 24 cases.Concomitant procedures included the bypass from the left subclavian artery to the left common carotid artery in 5 cases,aortic valve replacement and ascending aortic plasty in 3 cases,left subclavian artery reconstruction in 2 cases,double valve replacement in 1 cases,and the bypass from ascending aorta to descending aorta each in one,repair of internal leakage in 1 case.2 patients underwent thoracoabdominal aorta replacement died after surgery due to multiple organ failure caused by postoperative bleeding.The hospital mortality was 2.5％(2/81 cases).Complications occurred in 6 patients (6/81 cases,7.4.％ ),including diastinal bleeding requiring reoperation in 3 cases,respiratory insufficiency and hoarseness each in one,postoperative esophageal fistula needed reoperation and jejunal fistulization in I case.No paraplegia or stroke occurred postoperatively.Logistic regression analysis shows Marfan syndrome is the risk factor of reoperation.Conclusion The surgery on Stanford B aortic dissection can achieve satisfactory clinical results and Marfan syndrome is the risk factor of reoperation.The mid- and long-term results need the further follow-up.
