大隐静脉曲张激光闭合术应用温度反馈式机械臂的初步研究

Preliminary study on temperature feedback manipulator in endovenous laser ablation for great saphenous varicose vein

目的 :初步探讨温度反馈式机械臂在大隐静脉腔内激光闭合术(endovenous laser ablation,EVLA)中的应用。方法:2012年7月至12月收治的80例大隐静脉曲张病人分成两组:机械臂组(26例)和常规组(54例),分别实施机械臂控制的EVLA和常规EVLA,对两组的并发症发生率、主干再通率、复发率进行比较。结果:机械臂组在皮肤灼伤、患肢麻木并发症方面低于常规组(0比14.8%和15.4%比25.9%,P<0.01);术后2年大隐静脉主干再通率,机械臂组也低于常规组(3.8%比13.0%,P<0.01)。结论:机械臂控制大隐静脉EVLA具有一定的可行性。

Objective To study preliminarily on endovenous laser ablation （EVLA） for great saphenous varicose veins using mechanical arm with temperature feedback. Methods Eighty cases with great saphenous varicose vein from July to Dec 2012 were included in this study and divided into two groups with 26 cases in mechanical arm group and 54 cases in control group. The cases in mechanical arm group underwent EVLA with mechanical arm while those in control group EVLA only. The morbidity, recanalization and recurrence of varicose vein were compared between two groups. Results The skin burn and paralysis were found lower in mechanical arm group than in control group （0 vs 14.8% and 15.4% vs 25.9%, P〈0.01）. The recanalization two years later was lower in mechanical arm group than in control group （3.8% vs 13.0%, P〈 0.01）. Conclusions Mechanical arm might be useful in the procedure of EVLA for great saphenous varicose veins.
