Abstract: ［Abstract］Objective〖HTSS〗To summarize the clinical experience of No-Touch technology to obtain vein grafts, and compare with the traditional long-incision method to obtain lower limb complications after vein grafts.
〖WTHZ〗Methods〖HTSS〗A total of 201 patients who underwent off-pump coronary artery bypass grafting(CABG) were selected. The control group consisted of 59 patients obtain vein grafts by traditional long incision, and the experimental group consisted of 142 patients obtain vein grafts by No-Touch technique. Comparison of postoperative lower limb complications between 2 groups.
〖WTHZ〗Results〖HTSS〗The incidence of pain or numbness, edema or exudation and subeschar healing in the test group was significantly higher than that in the control group(P＜0.05). There was no significant difference in the incidence of infection or dehiscence between two groups(P＞0.05).
〖WTHZ〗Conclusion〖HTSS〗The incidence of lower limb complications in obtaining vein grafts by No-Touch technique is significantly higher than that by traditional long incision. The related factors with high complications of lower limb after obtaining vein grafts with No-Touch technique should be further explored.
