ABSTRACT
Objective To sum up the clinical information and outcomes of one-stage surgical repairs for interrupted aortic arch (IAA) associated with cardiac defects through median stemotomy in infant.Methods From August 2005 to January 2012,23 IAA patients,aged 18 days to 3 years [mean age (8.61 ± 11.81) months],body weight 3.3-13.0 kg [mean (6.61 ± 3.26) kg] were reviewed underwent one-stage repair.There were 12 male and 11 female.The anatomic subtype ineluded type A 20 (87.0％),type B 3 (13.0％),and no type C in the records.All cases included ventricular septal defect and patent ductus artefious,some also with artirical-pulmonary window,aterical septal defect,bicuspid or unicuspid aortic valve,and subvalvular aortic stenosis.Diagnosis was determined in of the patients and suspected in by echocardiography.Also,64 layers helico-CT was employed to make a definite diagnosis for 18 patients and cardiac catheterization was used for 4 patients.All patients with cardiac anomalies underwent one-stage repair through median sternotomy.The aortic continuity was reestablished by anastomosis between the descending aortic segment and aortic arch.Results In all 23 cases,21 were successful.There was 2 (8.69％) postoperative death:one was due to surgical hemorrhage and severe low cardiac output during perioperative stage and the other was 2-month old due to crisis of pulmonary hypertension.CPB time was ranged from 53-215 min [(129.76 ± 38.98) min],and aortic crossclamp time was 34-125 min[(74.47 ± 24.30) min].The length of stay in ICU postoperatively was 96h averagely.The postoperative complications included severe low cardiac output syndrome in 3 patients,hypoxemia in 13,pneumonia in 7,and supraventricular tachycardia in 12.21 patients were followed up from 2 months to 6 years and were in good condition without recoactation.Conclusion The outcomes of early and medium term for one-stage repair of IAA and associated cardiac anomalies through median stemotomy is excellent.Technique of extended anastomosis between the descending aortic segment and aortic arch may reduce the incidence of recoarctation.It is simplified the procedure and improved life quality of patients.
ABSTRACT
Objective To review the clinical experiences of modified Nuss procedure and technique for complicated pectus excavatum. Methods From September 2006 to October 2009,45 children (27 boys and18 girls), aged 3 - 16 years [mean (6.4 ± 3.5 )years] with complicated pectus excavatum underwent modified Nuss procedure. VATS was used in 6 cases. 3 patients associated with lung cyst were treated by open surgery and 1 case with ASD was treated by Hybrid procedure.Results The surgery was successfully performed in all patients. The mean operative time was 54 minutes and the average hospital stay was 7 days. Postoperative evaluation was"excellent"in 30 cases , "good"in 13, and"moderate"in 2. Conclusion Modified Nuss procedure is a safe and effective method for correction of complicated pectus excavatum.
