Abstract
Objective: To report on the surgical treatment of varicose veins by angioscopic valvuloplasty to preserve the long saphenous vein (LSV) and the efficacy of this method compared with conventional stripping and high ligation. Methods: A total of 306 limbs in 187 patients with reflux at the sapheno-femoral junction to below knee level were operated on using intraoperative angioscopy to diagnose valve insufficiency. Angioscopic external valvuloplasty was attempted for the subterminal valves in the LSV by three techniques: total plication of the dilated annulus by running polypropylene sutures (technique 1), plication by autogenous femorofascial sleeve or Dacron-reinforced silicone (technique 2), and plication of the commissure with shortening of the cusps from outside the vein wall (technique 3). Partial stripping or segmental ligation was performed for varicose veins below knee level and the incompetent perforating veins were treated simultaneously by suprafascial ligation. Results: The subterminal valves were classified as follows: valves with elongated and atrophic cusps – type I, 136 (44%); valves with expanded and depressed commissures with cusp changes – type II, 108 (35%); valves that had cusps with other deformities – type III, 38 (13%); and absence of valves between the saphenofemoral junction and mid-thigh level, 24 limbs (8%). Valvuloplasty of the LSV was successfully performed in 62 limbs (20%). There were two cases with occlusion of the LSV (3%) and four with recurrence of varicose veins (6%) at 2–89 (mean 55, SD 21) months follow-up. Conclusions: Angioscopic external valvuloplasty is effective in the treatment of varicose veins to preserve the LSV. Further data are needed for complete evaluation of this procedure.
