Sutureless skin closure in varicose vein surgery: preliminary results

To describe the preliminary results of a special method of wound closure in varicose vein surgery using the tissue adhesive butyl-2-cyanoacrylate.

Eighteen consecutive young women (mean age 23 years) underwent partial stripping of the greater saphenous vein for varicose veins of the lower limbs by an external phleboextractor. Their wounds were closed without sutures by means of the adhesive butyl-2-cyanoacrylate. The cutaneous edges were drawn together by linear traction between forceps and the adhesive was applied and allowed to set. Less than 0.5 ml of adhesive was required to complete the entire procedure. Wounds were evaluated at 7 days for infection, dehiscence, and tissue reactions. At 6 months all wounds were rated for cosmesis using a validated visual analog scale, that is, a 100 mm line with "worst scar" at the right end of the line and "best scar" at the left end. All patients were interviewed about their acceptance of tissue adhesive skin closure.

The mean time required to close the epidermis with the adhesive was 117 seconds. All patients were followed up for 6 months. At 7 days no adverse outcomes had occurred. Results of wound evaluation at 6 months by the visual analog scale showed scores of 22.2 +/- 13.8 mm (optimal). The percentage of optimal scores was 94.4%, and only one patient (5.6%) had a suboptimal score. Inquiry into the patient's opinions suggested that this procedure was very acceptable.

Preliminary results with sutureless skin closure in varicose vein surgery have been very encouraging. This fast and cosmetic method of wound repair can replace the need for skin sutures in varicose vein surgery.
