A total of 12 cases underwent repair of complete atrioventricular (AV) septal defect utilising the two-patch technique. There were 4 males and 8 females. The mean age at repair was 9.6 months (range, 3 to 49 months). The average weight was 5.4 kg (range, 3.5 to 13 kg). Five had associated patent ductus arteriosus. A Gore-Tex patch and glutaraldehyde preserved pericardium was utilised for the ventricular and atrial portions of the defects respectively in all patients. Four of these were done under hypothermic circulatory arrest. There were no intra-operative deaths. Early mortality comprised of 2 patients (2/12, 16.6%). One due to a pulmonary hypertensive crisis and the other to septicemia. The mean duration of ventilatory support was 62 hours (range, 24 to 192 hours). The mean duration of inotropic support was 57 hours (range, 24 to 192 hours). Primary repair of AV septal defects using the two-path of technique can be accomplished with a low early mortality in carefully selected patients.
共有12例患者采用双补片技术修复完全性房室间隔缺损。其中男性4例，女性8例。修复时的平均年龄为9.6个月（范围3至49个月）。平均体重为5.4千克（范围3.5至13千克）。5例合并动脉导管未闭。所有患者均分别使用戈尔特斯补片和戊二醛保存的心包修复缺损的心室和心房部分。其中4例在低温循环停搏下完成手术。无术中死亡。早期死亡率为2例患者（2/12，16.6%）。1例死于肺动脉高压危象，另1例死于败血症。通气支持的平均持续时间为62小时（范围24至192小时）。强心药物支持的平均持续时间为57小时（范围24至192小时）。对于精心挑选的患者，采用双补片技术进行房室间隔缺损的一期修复可实现较低的早期死亡率。
