目的 :传统的动脉导管未闭手术切口采用左后外侧切口 ,对机体的损伤较大 ,作者设计并探讨左腋下小横切口行动脉导管结扎术的临床应用。方法 :采用左腋下小横切口行小儿动脉导管结扎术 12例 ,平均年龄 4 3岁 (2～ 6岁 )。结果 :全组手术野显露满意 ,无死亡及并发症病例。切口平均长度 4 2cm ,平均手术时间 45分钟 ,平均住院日 8 8天。讨论 :此方法具有切口小、切断呼吸肌少、出血少、手术时间短 ;手术疤痕隐蔽、微小 ,不影响外观 ;无胸腔闭式引流管 ,术后恢复快 ,可早期出院 ,住院时间短 ,住院费用少等优点。对设备要求不高 ,易于在基层医院开展 Objective: The traditional patent ductus arteriosus incision with the left posterolateral incision, the greater the damage to the body, the author designed and discussed the left axillary small transverse incision arterial catheter ligation clinical application. Methods: Left axillary small transverse incision pediatric artery catheterization in 12 cases, the average age of 43 years (2 to 6 years old). Results: The whole group showed satisfactory surgical field, no death and complications. Incision average length 4 2cm, the average operation time 45 minutes, the average length of stay 8 8 days. Discussion: This method has a small incision, less cut off the respiratory muscle, less bleeding, shorter operative time; surgical scar hidden, tiny, does not affect the appearance of closed thoracic drainage tube, fast recovery, early discharge, hospitalization time is short, Hospitalization costs less advantages. The equipment is not demanding, easy to carry out in primary hospitals
