Abstract:Objective To summarize the clinical characteristics and surgical treatment experience of complex aortic coarctation. Methods The clinical data of 15 patients with complex coarctation of aorta who were diagnosed by echocardiography and CT angiography from January 2010 to June 2017 were retrospectively analyzed.All patients underwent cardiac malformation correction under cardiopulmonary bypass,and then underwent selective cerebral perfusion or deep hypothermic circulatory arrest,resection of the constricted segment and posterior end-to-end anastomosis to correct aortic coarctation.There were 7 cases of direct arch-descending aorta anastomosis,5 cases of ascending aorta-descending aorta bypass,2 cases of ascending aorta-abdominal aorta bypass and 1 case of enlarged angioplasty with constricted aortic patch.The clinical manifestations,treatment methods and prognosis were analyzed. Results The operation proceeded smoothly,1 case died of heart failure in the early stage after operation,1 case of delayed chest closure due to bleeding in operation field,1 case of hemostasis after second thoracotomy and 1 case of dialysis.All 14 cases were followed up for 11 months to 8 years,with an average of 49 months.The difference of blood pressure between upper and lower limbs was less than 20 mm Hg.Two adult patients needed to take antihypertensive drugs for a long time after operation.Echocardiography and CT angiography showed that the artificial blood flow was smooth and no pseudoaneurysm was found at the anastomotic site. Conclusion Individualized treatment should be selected according to the clinical characteristics of patients with complex aorta coarctation,and one-stage operation is safe and effective.
