F or many years, the standard operation for varices of great saphenous veins (GSV) was the selective stripping, stab avulsion and sclerotherapy of the varicosities. 1) Rec ently, however, endovenous laser and radio-frequency ablation of GSV have become new standard techniques. In both techniques, the below-knee GSV is usually preserved in order to prevent nerve injury. As a result, reflux in the below-knee saphenous vein often persists after the operation.The aim of this study was to analyze the influence of persistent below-knee saphenous reflux and incompetent calf perforating veins on venous function after stripping.
MaterIals and MethodsFrom September 2007 to October 2008, 939 limbs (627 patients) were treated at Hiroshima Teishin Hospital. During this period, 131 limbs (131 patients) with varicosities of one side of the GSV were analyzed for this study.The patients were interviewed before surgery, one month after the operation, and one year after the operation. The venous filling index (VFI: normal range is lower than 2.0 ml/sec) was measured by air plethysmography, and persistent below-knee saphenous reflux was evaluated by duplex scanning. Persistent reflux was diagnosed when the reflux time was over 0.5 seconds using Persisting incompetent great saphenous vein (GSV) below the knee and residual incompetent perforating veins (IPV) are often found after selective stripping of GSV from the groin to upper calf. The aim of this study is to evaluate the venous function when the calf GSVs or calf perforating veins are incompetent after stripping surgery. One hundred-thirty-one limbs were treated by stripping from the groin to upper calf with stab avulsion or sclerotherapy of varices. One month and twelve months after surgery, the patients were examined clinically to establish the extent of persisting varices by duplex ultrasonography and air-plethysmography. Venous filling index (VFI) was a little higher in those who had residual calf GSV reflux 12 months later; it was also higher in the group with incompetent perforating veins than the group without. The chief complaints were found to have improved in all groups. The findings suggest that removal of the saphenous vein below the knee is not necessary, but it is important to take care of the incompetent perforating veins.
