不接触技术对冠状动脉旁路移植术后静脉桥通畅率影响的进展

Progress of Effect of No-touch Technique on Patency Rate of Vein Grafts after Coronary Artery Bypass Grafting

冠状动脉旁路移植术(coronary artery bypass grafting,CABG)是目前治疗冠心病的有效方法,但冠状动脉旁路移植术后有比较高的静脉桥闭塞率,严重影响CABG术后的近、远期临床治疗效果。静脉获取技术被认为是影响远期通畅率的一个重要因素。与开放性大隐静脉获取技术相比,不接触技术获取大隐静脉时保留了血管外膜以及血管周围组织,同时避免高压扩张静脉。使用不接触技术获取的静脉进行冠状动脉旁路移植术后,静脉桥取得了较好的近、远期通畅率,但效果还需要进一步的临床证实。

Coronary artery bypass grafting （CABG） is an effective method for the treatment of coronary heart disease at present. However, there is still a high rate of vein graft occlusion after CABG, which has a serious impact on the short and long-term clinical results. Venous access technique has been considered as an important factor on affecting the long-term patency rate. Compared with harvesting technology of the open saphenous vein harvesting, no-touch technology retained the surrounding tissue and vascular adventitia of great saphenous vein, and it avoided the high pressure of expansion vein. After CABG was performed by using the no-touch technique, the vein grafts obtained a better short and long-term patency rate, but the effect still needs further clinical verification.
