Abstract:
BACKGROUND: Pulmonary artery banding(PAB) accompanies some risks in the aspect of band complications and mortality in the second-stage operation. To assess these risks of the second-stage operation after PAB, we reviewed the surgical results of the second-stage operation in the pediatric patients who had undergone PAB in infancy. MATERIAL AND METHOD: From May 1988 to June 1997, a total of 29 patients with preliminary PAB underwent open heart surgery. Ages ranged from 2 to 45 months(mean 20.6+/-9.0 months). Preoperative congestive heart failure conditions were improved after PAB(elective operation group) in 27 patients, but early second-stage procedures were required in the remaining 2 patients due to sustaining congestive heart failure(early operation group). Preoperative surgical indications included 2 double outlet right ventricles(DORV group) and 27 ventricular septal defects as the main cardiac anomaly(VSD group). RESULT: The mean time interval from PAB to the second-stage operation was 15.5+/-8.7 months(range 5 days to 45 months). One patient in the DORV group underwent intraventricular tunnel repair and modified Glenn procedure in the other. In the VSD group, the VSD was closed with a Dacron patch in all patients. Concomitant procedures included a right ventricular infundibulectomy in 4 patients and a valvectomy of the dysplastic pulmonary valve in 1 patient. At the second-stage operations, pulmonary angioplasty was required due to the stenotic banding sites in 18 patients. One patient underwent complete ligation of the main pulmonary artery with the modified Glenn procedure. The mortality at the second-stage operation was 17.2%(5 patients). Causes of death were 4 low cardiac output, and 1 autoimmune hemolytic anemia. Diagnosis with DORV and the early operative group were the risk factors for operative death in this series. There was 1 late death. CONCLUSION: This study revealed the second-stage operation for pulmonary artery debanding and closure of VSD in children was complicated by the correction of the acquired lesions with a significantly high incidence of morbidity and early postoperative deaths. Primary repair is recommended for isolated VSD, if possible.
