Abstract

Groin wound infections in patients undergoing vascular procedures often cause a lengthy process of wound healing. Several clinical studies and case reports show a reduction of surgical site infections (SSIs) in various wound types after using closed incision negative pressure therapy (ciNPT). The aim of this prospective, randomised, single-institution study was to investigate the effectiveness of ciNPT (PREVENA™ Therapy) compared to conventional therapy on groin incisions after vascular surgery. From 1 February to 30 October 2015, 100 patients with 129 groin incisions were analysed. Patients were randomised and treated with either ciNPT (n = 58 groins) or the control dressing (n = 71 groins). ciNPT was applied intraoperatively and removed on days 5-7 postoperatively. The control group received a conventional adhesive plaster. Wound evaluation based on the Szilagyi classification took place postoperatively on days 5-7 and 30. Compared to the control group, the ciNPT group showed a significant reduction in wound complications (P < 0·0005) after both wound evaluation periods and in revision surgeries (P = 0·022) until 30 days postoperatively. Subgroup analysis revealed that ciNPT had a significant effect on almost all examined risk factors for wound healing. ciNPT significantly reduced the incidence of incision complications and revision procedures after vascular surgery.
