Hem-o-lok结扎夹行动脉导管夹闭术84例临床分析

目的探讨直视下采用Hem—o-10k结扎夹行动脉导管夹闭术的临床价值。方法2001年5月-2007年5月，对84例管型动脉导管采用左腋下小切口直视下释放1—2枚Hem—o—lok结扎夹夹闭。结果手术时间30～60min，平均42min。84例术中无出血，术后杂音消失，无手术死亡。84例随访2～50个月，平均28个月，无残余分流及再通。结论Hem—o—lok结扎夹治疗管型动脉导管未闭是一种创伤小、安全可靠的方法。

Closure of Patent Arterial Duct Using Hem-o-lok Polymer Ligating Clip

Objective To report our experience on closure of patent arterial duct using Hem-o-lok polymer ligating clip under a direct vision. Methods From May 2001 to May 2007, 84 patients with cast patent arterial duct were treated with Hem-o-lok polymer ligating clips. Under a direct vision, the clips were placed to close the patent arterial duct through a small left subaxillary incision. Results The mean operation time was 42 minutes （ranged from 30 to 60）. No intraoperative bleeding occurred in this series. After the operation, heart murmur disappeared in all the patients and none of them died. They were followed up for 2 to 50 months （mean 28 months） , during which no residual shunting or recanalization occurred. Conclusion It is microinvasive and safe to close patent arterial duct by using Hem-o-lok polymer ligating clip.
