Identification of risk factors for mortality in subclavian-pulmonary anastomosis using polytetrafluorethylene (PTFE).
Immediate surgical results (30 days) were analyzed in 180 cyanotic patients consecutively operated on from september 1979 to march 1989.
The hospital mortality was 12.7% (23 patients) and age at surgery, low weight (less than 3 kg) and preoperative diagnosis were considered risk factors for mortality. Pulmonary artery diameter at echocardiography, date of surgery and diameter of the conduits were associated with increased risk, but this association lacked statistical significance. Sex and previous palliative surgery have not increased hospital mortality.
We believe that identification of risk factors to PTFE conduit implant plays an important role in the preoperative management of those patients in order to obtain better results in this life saving procedure.
确定使用聚四氟乙烯（PTFE）进行锁骨下动脉-肺动脉吻合术时的死亡危险因素。
分析了1979年9月至1989年3月期间连续接受手术的180例发绀型患者的即刻手术结果（30天）。
医院死亡率为12.7%（23例患者），手术时年龄、低体重（小于3千克）和术前诊断被认为是死亡的危险因素。超声心动图检查时的肺动脉直径、手术日期和管道直径与风险增加相关，但这种关联缺乏统计学意义。性别和既往姑息性手术并未增加医院死亡率。
我们认为，确定PTFE管道植入的危险因素在这些患者的术前管理中起着重要作用，以便在这种挽救生命的手术中取得更好的效果。
