Randomized Controlled Trial Multicenter Study Comparative Study
Endovenous laser ablation with and without high ligation compared with high ligation and stripping in the treatment of great saphenous varicose veins: initial results of a multicentre randomized controlled trial.
To compare reflux recurrences at the saphenofemoral junction after endovenous laser ablation (EVLA) with or without high ligation with high ligation and stripping (HL/ST) of the great saphenous vein (GSV) in patients with varicosity of the GSV. Design Multicentre, randomized, three-arm, parallel trial. Material and Methods Patients with varicosity of the GSV were randomized to one of three groups: HL/ST, laser ablation (980 nm) or a combination of laser ablation with high ligation (EVLA/HL). Patients were examined clinically and by ultrasound pre- and postoperatively and after two months. The primary endpoint of this ongoing study is the inguinal venous reflux (IVR) in the proximal section of the GSV after two years. We present data after two months. Secondary endpoints include postoperative ecchymosis, pain or discomfort, saphenous syndrome. Groups were compared by chi-squared test. ⋯ After two months IVR was more often seen in both EVLA groups compared with the HL/ST group. There were significantly more postoperative ecchymosis in the HL/ST. Postoperative pain occurred significantly more often in the EVLA/HL group. Peri- and postoperative data showed significant differences between the three groups. For definitive results concerning the primary endpoint of IVR the later follow-up has to be waited for.

Randomized Controlled Trial Multicenter Study Comparative Study
Tumescent anaesthesia in combination with femoral nerve block for surgery of varicose veins: prilocaine 0.1% versus 0.2%.
Results of a prospective, randomized, double-blinded study about tumescent anaesthesia (TA) in combination with femoral nerve block (FNB) for surgery of varicose veins are reported. The aim is to compare two different concentrations of prilocaine in TA. ⋯ TA with prilocaine 0.1% in combination with FNB is sufficient to provide high patient satisfaction during varicosis surgery.

Randomized Controlled Trial
Long saphenous tunnel infiltration with levobupivicaine reduces rescue analgesia requirements following varicose vein surgery: randomized, double-blind, placebo-controlled trial [ISRCTN58431114].
To determine whether local anaesthetic infiltration of the long saphenous tunnel in patients undergoing unilateral, primary long saphenous stripping and multiple avulsions reduces early postoperative pain and requirement for opiate analgesia. ⋯ In varicose vein surgery, local anaesthetic infiltration to the groin wound and along the full length of the stripper track is associated with reduced postoperative pain and requirements for opiate analgesia.
