动脉导管未闭的外科治疗和并发症分析

目的：探讨不同类型动脉导管未闭（PDA）的外科手术式选择，并就其常见并发症进行分析。方法：408例患者，分别采用后外侧切口双重结扎，全身浅低温双重结扎，以及正中劈胸骨体外循环辅助下经心包内分离双重结扎PDA，或切开肺动脉直视下缝闭PDA。结果：早期死亡4例（0．98％），再通5例，发生乳糜胸2例，其余均痊愈出院，结论 ：对不同类型动脉导管未闭采用不同的手术方法，能减少并发症的发生，取得良好的手术效果。

Surgical treatment of patent ductus arterious and analysis of its complication

Objective To evaluate the surgical techniques of patent ductus arterious(PDA) and analyse its complication.Methods Four hundred and eight patients were undergone the surgical treatment.The surgical techniques included double ligation for closure PDA through the left posterolateral thoracotomy and suture PDA via median sternotomy on bypass.Results There were 4 patients early death(0.98%),5 patients residual shunt,and 2 patients chylothorax. The others were cured.Conclusion Satisfied surgical results rely mainly on proper operation techniques according the different PDA. Double ligation for closure PDA is safty and effection through the left posterolateral thoracotomy in most patients with single PDA. But in patients with the intracardiac malformation of pulmonary hypertension,the procedure should be conducted via median sternotomy on bypass.
