A total of 139 open vascular surgical procedures including a groin incision were studied; bilateral procedures had one of each type of dressing. Negative pressure wound therapy reduced the risk of surgical site infection: 11.9 versus 29.5 per cent in unilateral procedures, and 5.3 versus 26.3 per cent in bilateral procedures, overall P=0.02.
