Abstract:Objective To summarize the experiences of single stage repair of interrupted aortic arch （IAA） associated with cardiac anomalies. Methods From Jan. 2000 to Dec. 2005, 48 patients admited in hospital and 35 patients were operated, the mean age at operation was 1.1 years. The associated anomalies included 23 cases of ventricular septal defect, 2 cases of transposition of great arteries, 3 cases of aortopulmonary window with aortic origin of right pulmonary artery, 2 cases of truncus arteriosus, 2 cases of double outlet right ventricle, 2 cases of stenotic fifth arch and 1 case of aberrant origin of right subclavian artery with mild hypoplastic decending aorta. Among them, 34 patients underwent single stage repair and 1 kid underwent palliative correction. Results There were 4 surgical deaths. The sequelae included one diaphragm paralysis and one 3rd degree of atrioventricular block. Only 5 kids recurred mild stenosis of aortic arch anastomosis and 2 death occurred during 3 months to 4 years of follow-up. Conclusion Though early surgical mortality for primary single stage repair is now relatively low, if appropriate interventions has been accomplished during perioperative period, but outcomes of IAA remain of concern, especially in patients with associated lesions.
Objective To evaluate the outcome of surgical repair of interrupted aortic arch (IAA) combined with anomalies. Methods We retrospectively analyzed the clinical data of 48 patients with IAA combined with anomalies undergoing one-stage biventricular repair in Shanghai Children's Medical Center from November 2006 to April 2016. There were 25 males and 23 females with a median age of 29 d (range, 8 to 91 d) and a mean weight of 3.80±0.67 kg. All patients underwent end-to-end anastomosis with patch augmentation, and relief of left ventricular outflow tract obstruction (LVOTO) was performed in 11 patients. Results In IAA children with anomalies, 39 (81.3%) suffered noncomplex lesions and 9 (18.8%) complex lesions. Mean follow-up was 72.1±19.7 months for 38 patients. There were 6 in-hospital deaths and 3 patients died during follow-up. The early survival rate was 87.5%, 5-year rate 83.3% and 10-year rate 81.3%. Reintervention was required in 10 patients, including 8 with subsequent LVOTO and 2 with anastomotic stenosis. Conclusion End-to-end anastomosis with patch augmentation is effective for IAA.
