The aim of this study is to understand that Wound complications after major lower extremity amputations (LEAs) are a cause of significant morbidity in vascular surgery patients. Recent publications have demonstrated the efficacy of the closed incision negative pressure dressing at preventing surgical site infections (SSIs); however, there are few data on its use in major LEAs. This study sought to assess if closed incision negative pressure wound therapy (NPWT) would decrease the risk of complications as compared with a standard dressing in patients with peripheral vascular disease undergoing major LEA.

Fifty-four consecutive patient limbs with a history of peripheral arterial disease underwent below-knee or above-knee amputations. This was a retrospective review of a prospectively maintained database from January 2018 to December 2019, and it included 23 amputations in the NPWT group and 31 amputations in the standard dressing group. NPWT using the PREVENA system was applied intraoperatively at the discretion of the operating surgeon and removed 5 to 7 days postoperatively. The standard group received a nonadherent dressing with an overlying compression dressing. Amputation incisions were assessed and wound complications were recorded. Student’s t-test and two-sample proportion z-test were used for statistical analysis. A P value of less than .05 was considered statistically significant.
