| Scientific title | Surgery as a trigger for neorevascularisation in recurrent saphenofemoral incompetence: a randomised trial of three different techniques |
| Study objectives | Surgery itself, and maybe the type of surgery, may trigger neorevascularistion in the groin when treating sapheno-femoral incompetence.The hypothesis is that one of the following three techniques is better - inducing less neorevascularisation - than the other two. If this would be the case this one technique should be preferred to the other two, worldwide. The three techniques are: 1. Dissection under ligation 2. Dissection with electrocoagulation 3. Ultrasonic dissection |
| Ethics approval(s) | Ethics Commission of the Regionalspital Thun approved on the 1st March 2002 (ref: 2:4;1.3) |
| Health condition(s) or problem(s) studied | Recurrent varicose veins |
| Intervention | The study was approved by the local Human Ethics Committee. All patients included in the study have informed pre-operative consent. 36 consecutive unselected patients underwent redo saphenous high ligation procedures during a period of thirteen months (1st April 2002 - 30th June 2003). The study population comprised 34 female patients and 2 males. The age ranged from 24 to 73 years (mean 53 years). Thirty-two patients had undergone at least one previous procedure in the groin. The patients were randomised to receive either dissection with ultrasound (Ultracision Harmonic Scalpel, Ethicon Endo-Surgery, Johnson and Johnson Company, Spreitenbach, Switzerland) or electrocoagulation (Elektrotom Berchtold GmbH&Co, Tuttlingen, Germany) or sharp dissection with ligation of scar and lymphatic tissue using absorbable suture material (Vicryl, Ethicon Endo-Surgery, Johnson and Johnson Company, Spreitenbach, Switzerland). The groin was reopened via a transverse incision. The femoral artery was visualised as a landmark, after which the femoral vein was dissected and recurrent veins ligated and divided. Fascia and subcutaneous tissue was closed in two layers and included a vacuum wound drain. The skin was closed with sutures. Operating time is around one hour per procedure. The drain was removed one day post-operatively. After three months a clinical and colour duplex ultrasonography investigation (Acuson Aspen, Acuson Corporation, Mountain View CA, USA) were carried out to detect lymphatic complications. After seven years a clinical and colour duplex ultrasonography investigation were carried out to detect and describe type and extent of neorevascularisation for the patients of all three treatment arms. |
