Abstract:
Objective To analyze the clinical effect of partial aortic root remodeling for root reconstruction on Stanford type A aortic dissection. Methods From January 2010 to December 2015, 30 patients (25 males, 5 females) underwent partial aortic root remodeling for root reconstruction on Stanford type A aortic dissection with involvement of aortic root. The range of age was from 27 to 72 years, and the mean age was 51.2±8.0 years. The proximal aortic dissection received partial aortic root remodeling, and the operation procedures included partial aortic root remodeling+ascending aortic replacement in 9 patients, partial aortic root remodeling+ascending aortic replacement+hemi-arch replacement in 6 patients, partial aortic root remodeling+ascending aortic replacement+Sun's procedure in 15 patients. The patients were followed up for 10 to 60 months with a mean of 37.9±3.2 months. Preoperative and postoperative degrees of aortic regurgitation were compared. Results All patients survived from the operation, and one patient died from severe pulmonary infection 15 days after operation. The overall survival rate was 96.7% (29/30). One patient died during the follow-up. Two patients underwent aortic valve replacement in the 12th and 15th postoperative month respectively because of severe aortic regurgitation (AI). Up to the last follow-up, trivial or no aortic regurgitation was demonstrated in 24 patients, but mild aortic regurgitation occurred in 2 patients. Conclusion The surgical treatment for aortic root pathology due to Stanford type A aortic dissection is challenging, and partial aortic root remodeling operations could restore valve durability and function, and obtains the early- and mid-term results.
