One-stage repair of aortic coarctation or interrupted aortic arch associated with cardiac anomalies through median sternotomy / 中华胸心血管外科杂志

ABSTRACT

Objective Study the management and outcomes of one-stage repair of aortic coarctation or interrupted aortic arch associated with cardiac anomalies through median sternotomy.Methods From July 2002 to June 2009,43 patients with aortic coarctation(34 cases)or interrupted aortic arch(9 cases)and associated with cardiac anomalies underwent one-stage repair.There were 27 males and 16 females.The age ranged from 5 months to 9 years and the body weight from 3.5 kg to 29.0 kg.The associated cardiac anomalies included ventricular septal defect in 42 patients,patent ductus arterious in 34,secundum atrial septal defect in 12,subaortic stenesis in 5,mitral valve regurgitation in 2 and double outlet of right vantricule in 1.All patients underwent one-stage repair through median sternotomy.The aortic continuity was reestablished by direct anastomosis between the descending aortic segment and aortic arch.Results There was one postoperative death.The causs was pulmonary hypertension and severe low cardiac output syndrome.The postoperative complications included severe low cardiac output syndrome in 3 patients,hypoxemia in 6,pneumonia in 11,atelectasis in 14,injury of recurrent laryngeal nerve in 19,and supra ventricular tachycardia in 23.34 patients were followed up from 3 months to 5 years and were in good condition without recoarctation.Conclusion The outcomes of early and medium term for one-stage repair of aortic coarctation or interrupted aortic arch and associated cardiac anomalies through median sternotomy is excellent.Technique of extended anastomosis between the descending aortic segment and aortic arch may reduce the incidence of recoarctation
