合并心内畸形动脉导管未闭的外科治疗

目的 探讨合并心内畸形的动脉导管未闭（ＰＤＡ）的外科治疗，并就其常见并发症进行分析。方法 ６３例患者，分别采用正中劈胸骨经心包内分离双重结扎ＰＤＡ，或体外循环辅助下切开肺动脉直视下缝闭ＰＤＡ，同期行心内畸形矫治。结果 早期死亡３例（４．７６％）。发生呼吸衰竭７例，肾功能衰竭１例，严重室性心律紊乱１例。６０例痊愈出院，随访２个月至８年，恢复良好。结论 心内畸形合并ＰＤＡ应早行同期矫治，浅低温心脏跳动

Surgical treatment of patent ductus arteriosus associated with intracardiac malformation

Objective To evaluate the surgical techniques for patent ductus arteriosus (PDA) associated with intracardiac malformation. Methods Surgical management, including double ligation for closure of the ductus via median sternotomy, direct suture of pulmonary artery with cardiopulmonary bypass and the intracardiac malformation was repaired at the same time. Results Early death in 3 cases (4.76%) postoperatively, 7 were complicated with pulmonary failure, 1 with renal failure, and 1 with contractable ventricular arrhythmias. Sixty patients with a good recovery in a period of 2 months to 8 years follow up. Conclusion Simultaneous operations on patients with intracardiac malfor mation and PDA are safe and effective. PDA can be safely sutured in pulmonary artery on beating heart with mild hypothermic cardiopulmonary bypass.
