Abstract:
ObjectiveAnalyze the results of distal aortic reoperation in Marfan syndrome patients after proximal aortic surgery.MethodsBetween January 2000 and January 2010, 28 Marfan patients underwent surgical repair of distal aortic disease after aortic root surgery at our institution.There were 20 males and 8 females.Age ranged from 23 to 52 years [ mean (38.5 ± 8.7) years ].First time operations were Bentall procedure in 24, David procedure in 4.There were 8 cases of Stanford A dissection and 20 cases of aortic root aneurysm.The second time operations included 1 partial aortic arch replacement, 2 total arch replacements, 7 total arch replacements combined with stent elephant trunk, 6 descending thoracic aorta replacements,10 thoracoabdominal aorta replacements and 2 total aorta replacements.The interval between the lst and 2nd operation was 1 to 12 years [mean (6.43 ±3.07) years].The surgical technique used for distal procedures was dependent on the pathology of the aorta.Median repeat sternotomy was used for surgical exposure in 10 patients, who required an arch/proximal descending aortic procedure.Cardiopulmonary bypass (CPB) was established through the right axillary perfusion and right femoral venous drainage in all of these patients.16 patients were operated on through a left-sided incision, namely, a posterolateral thoracotomy, or a thoracoabdominal incision, depending on the distal extent of aortic replacement.For such patients, the left femoral vessels were cannulated for CPB in 14 patients and the rest 2 patients were operated on without CPB.Two patients with total aorta replacement were operated on through a median sternotomy combined with thoracoabdominal incision.22 patients underwent deep hypothermic circulatory arrest because of the replacement of anrtic arch or the extensive aneurismal arch.Reconstruction of intercostal arteries (T8-L1) was performed in 16 patients for the protection of spinal cord.ResultsTwo patients (7.1％) died postoperatively.Neurological morbidity included 1 patient with stroke, 1 paraplegia and 2 temporary paraparesisThree patients required temporary tracheotomy for prolonged weaning form the respirator.All patients were followed up for 10-118 months [mean (40.8 ±29.5) months].Two patients died during follow-up.The survival rate was (94.5 ± 1.3)％,(90.6 ± 1.4) ％ at 1-and 5-year, respectively.ConclusionDistal aortic reoperation in Marfan patients can be performed with good short-and long-term results.Complete aortic arch replacement with elephant trunk technique, if safely performed,should be considered for Marfan patients presenting with type A dissection.
