title: [Late reoperations after repaired Stanford type A aortic dissection].
abstract: Objective:To summarize the experience of reoperations on patients who had late complications related to previous aortic surgery for Stanford type A dissection.Methods:From August 2008 to October 2016, 14 patients (10 male and 4 female patients) who underwent previous cardiac surgery for Stanford type A aortic dissection accepted reoperations on the late complications at Department of Thoracic and Cardiovascular Surgery, Nanjing Hospital Affiliated to Nanjing Medical University. The range of age was from 41 to 76 years, the mean age was (57±12) years. In these patients, first time operations were ascending aorta replacement procedure in 3 patients, ascending aorta combined with partial aortic arch replacement in 4 patients, aortic root replacement (Bentall) associated with Marfan syndrome in 3 patients, aortic valve combined with ascending aorta replacement (Wheat) in 1 patient, ascending aorta combined with Sun's procedure in 1 patient, Wheat combined with Sun's procedure in 1 patient, Bentall combined with Sun's procedure in 1 patient. The interval between two operations averaged 0.3 to 10.0 years with a mean of (4.8±3.1) years. The reasons for reoperations included part anastomotic split, aortic valve insufficiency, false aneurysm formation, enlargement of remant aortal and false cavity. The selection of reoperation included anastomotic repair, aortic valve replacement, total arch replacement and Sun's procedure.Results:Of the 14 patients, the cardiopulmonary bypass times were 107 to 409 minutes with a mean of (204±51) minutes, cross clamp times were 60 to 212 minutes with a mean of (108±35) minutes, selective cerebral perfusion times were 16 to 38 minutes with a mean of (21±11) minutes. All patients survived from the operation, one patient died from severe pulmonary infection 50 days after operation. Three patients had postoperative complications, including acute renal failure of 2 patients and pulmonary infection of 1 patient, and these patients were recovered after treatment. Thirteen patients were finally recovered from hospital. The patients were followed up for 16 to 45 months, and no aortic rupture, paraplegia and death were observed in the follow-up.Conclusions:Patients for residual aortic dissection after initial operations on Stanford type A aortic dissection should be attached great importance and always need emergency surgery, but the technique is demanding and risk is great for surgeons and patients, which need enough specification and accurate on aortic operation. More importantly, the Sun's procedure also should be performed on the treatment of residual aortic dissection or distal arch expansion, and obtains the short- and long-term results in the future.
