ObjectiveTo compare early clinical outcomes between systemic-pulmonary shunts (SPS) and right ventricular to pulmonary artery connection (RV-PA connection) for patients with pulmonary atresia and ventricular septal defect (PA/VSD), and investigate early management strategies for these 2 different palliative procedures. MethodsWe retrospectively analyzed clinical data of 89 PA/VSD patients who underwent SPS or RV-PA connection in Fu Wai Hospital from January 2009 to December 2011. According to different surgical procedures, all the 89 patients were divided into 2 groups. In SPS group, there were 59 patients including 35 males and 24 females with their median age of 25 months (4 months to 8 years). In RV-PA connection group, there were 30 patients including 19 males and 11 females with their median age of 24 months (28 days to 7 years and 2 months). Early clinical outcomes including mechanical ventilation time, length of ICU stay, morbidity, reexploration, improvement of oxygen saturation (SO2) and mortality were compared between the 2 groups. ResultsAmong 59 patients in SPS group, 3 patients (5.1%) died postoperatively. There was no in-hospital death among 30 patients in RV-PA connection group. The improvement of percentage of SO2 of RV-PA connection group was significantly higher than that of SPS group (31.7% vs. 22.2%, P < 0.05). There was no statistical difference in length of ICU stay (3.6±2.5 days vs. 4.2±5.1 days, P > 0.05), mechanical ventilation time (34.8±33.5 hours vs. 44.3±39.6 hours, P > 0.05), postoperative morbidity (37.3% vs. 30.0%, P > 0.05) or reexploration rate (15.3% vs. 6.7%, P > 0.05) between SPS group and RV-PA connection group. Incidence of serious postoperative complications of SPS group was signi-ficantly higher than that of RV-PA connection group (25.4% vs. 6.7%, P < 0.05). ConclusionEarly clinical outcomes of RV-PA connection is better than SPS for PA/VSD patients including greater SO2 improvement and lower mortality. Mid-term and long-term clinical results as well as larger study samples are needed for better evaluation.
