Abstract:
BACKGROUND: Pulmonary artery banding (PAB) is an initial palliative procedure for a diverse group of patients with congenital cardiac anomalies and unrestricted pulmonary blood flow. We proved the usefulness of PAB through retrospective investigation of the surgical indication and risk analysis retrospectively. MATERIAL AND METHOD: One hundred and fifty four consecutive patients (99 males and 55 females) who underwent PAB between January 1986 and December 2003 were included. We analysed the risk factors for early mortality and actuarial survival rate. Mean age was 2.5+/-12.8 (0.2~92.7) months and mean weight was 4.5+/-2.7 (0.9~18.0) kg. Preoperative diagnosis included functional single ventricle (88, 57.1%), double outlet right ventricle (22, 14.2%), transposition of the great arteries (26, 16.8%), and atrioventricular septal defect (11, 7.1%). Coarctation of the aorta or interrupted aortic arch (32, 20.7%), subaortic stenosis (13, 8.4%) and total anomalous pulmonary venous connection (13, 8.4%) were associated. RESULT: The overall early mortality was 22.1% (34 of 154). The recent series from 1996 include patients with lower age (3.8+/-15.9 vs. 1.5+/-12.7, p=0.01) and lower body weight (4.8+/-3.1 vs. 4.0+/-2.7, p=0.02). The early mortality was lower in the recent group (17.5%; 16/75) than the earlier group (28.5%; 18/45). Aortic arch anomaly (p=0.004), subaortic stenosis (p=0.004), operation for subaortic stenosis (p=0.007), and cardiopulmonary bypass (p=0.007) were proven to be risk factors for early death in univariate analysis, while time of surgery (<1996) (p=0.026) was the only significant risk factor in multivariate analysis. The mean time interval from PAB to the second-stage operation was 12.8+/-10.9 months. Among 96 patients who survived PAB, 40 patients completed Fontan operation, 21 patients underwent bidirectional cavopulmonary shunt, and 35 patients underwent biventricular repair including 25 arterial switch operations. Median follow-up was 40.1+/-48.9 months. Overall survival rates at 1 year, 5 years and 10 years were 81.2% 65.0%, and 63.5% respectively. CONCLUSION: Although it improved in recent series, early mortality was still high despite the advances in perioperative management. As for conventional indications, early primary repair may be more beneficial. However, PA banding still has a role in the initial palliative step in selective groups.
