ABSTRACT

Objective To observe the feasibility and efficacy of small-incision high-ligation of great saphenous vein combined with endovascular microwave coagulation plus local injection of lauromacrogol for varicose veins of lower limbs . Methods From October 2012 to October 2013, there were 60 patients (70 legs) treated by high-ligation of the great saphenous vein , during which endovascular microwave coagulation was performed by using radiator and an additional injection of sclerotherapy at local tortuous vessels was carried out ( observation group ) .The control group ( between August 2011 and September 2012 ) underwent the traditional saphenous vein ligation plus superficial vein stripping surgery .The operation time , blood loss during operation , number of incisions , length of groin incision , and postoperative complications were compared between the two groups . Results As compared with the control group , the observation group had singnificantly shorter operative time , fewer blood loss , fewer surgical incisions , and shorter groin incision, respectively [(50.8 ±2.6) min vs.(103.5 ±16.0) min, t=-25.183, P=0.000;(43.2 ±4.6) ml vs.(107.5 ± 35.2) ml, t=-14.030, P=0.000;2.2 ±0.7 vs.6.3 ±2.5, t=-12.233, P=0.000;(2.3 ±0.3) cm vs.(4.8 ±0.3) cm, t=-17.697, P=0.000].There was no significant difference in complications rates between the two groups : local skin numbness occurred in 40 cases in the observation group and in 38 cases in the control group (χ2 =0.147, P =0.702 ) and subcutaneous congestion was noted in 4 cases in the observation group and in 9 cases in the control group (χ2 =2.157, P=0.142). Conclusion Small-incision high-ligation of the great saphenous vein combined with endovascular microwave coagulation plus local injection of lauromacrogol for varicose veins of lower limbs has advantages of minimal invasion , good cosmetic outcomes , quick recovery , high efficacy, fewer complications , and easy performance .
