Abstract

OBJECTIVE:

To determine the choice of palliative procedures, timing and techniques of second-stage operations.

METHODS:

Between April 2004 to July 2008, 50 consecutive patients with pulmonary atresia with ventricular septal defect (PA/VSD) underwent two-stage operation. Palliative procedures included modified Blalock-Taussig shunt (n = 5), central shunt (n = 2), pericardial patch enlargement (n = 10), pericardial tube (n = 4) and Gore-Tex conduit (n = 29). The interval period was 7 - 49 months (20.0 +/- 10.0 months). In the second stage, a surgical shunt was interrupted in 7 cases. Ventricular septal defect was closed in all patients, but fenestrated ventricular septal defect patch was used in 6 cases. Right ventricular outlet tract (RVOT) was widened with pericardial patch in 42 cases and conduit exchange in 8 cases. Aortopulmonary collateral arteries (MAPCASs) unifocalization (n = 1), ligation or transcatheter occlusion with embolization coils (n = 4) and maintaining open or untreated (n = 4).

RESULTS:

Death occurred in 2 and the mortality rate was 4%. Postoperative complications included residual shunt (n = 3), residual obstruction (n = 3), complete AV block (n = 1), athetosis (n = 1) and acute renal failure (n = 3). Neither death nor complication was reported during a follow-up period of 3 months to 4 years.

CONCLUSION:

A palliative procedure should be individualized to the patient's morphology of central pulmonary artery and clinical status of a patient. Right ventricular outlet tract reconstruction, pulmonary arterioplasty, fenestration of VSD patch in baby with suprasystemic right ventricular pressure and appropriate interventions with MAPCASs are key to decrease the mortality and morbidity of staged operations for PA/VSD.
