Systematic review of groin incision surgical site infection preventative measures in vascular surgery.

Objective: Groin surgical site infections (SSIs) after open revascularization can lead to devastating consequences in patients. As a result, prevention has been crucial in minimizing the rate of SSIs. This review aims to evaluate the current body of literature regarding prevention ,techniques including prophylactic flaps, incision technique, topical antibiotic use, closed-incision negative pressure wound therapy, and adhesive drapes.

Methods: This review was conducted and reported in accordance with the PRISMA statement. A systematic review was conducted using the Google Scholar, PubMed, and Cochrane Review databases regarding the five prevention topics. The authors identified 1371 potential studies with 33 studies selected and analyzed after systematic review regarding the five preventative topics.

Results: The primary outcome of interest was how the rate of SSI was affected with each preventative technique. As a result, the recommendations are as follows. We suggest prophylactic flaps be considered in high-risk surgical patients undergoing open arterial exposure of the groin (Grade 2C). We suggest consideration of transverse incisions for open arterial exposure of the groin as a means of SSI prevention (Grade 2C). Given the lack of data regarding topical antibiotics no recommendation can be made regarding its use, we suggest closed-incision negative pressure wound therapy be used in groin surgical incisions at high risk for SSI (Grade 2B). Given the paucity of data regarding adhesive drapes, such as Ioban, no recommendation can be made regarding its use.

Conclusions: This review highlights the effects of various preventative techniques and their potential benefit in the prevention of SSI in the groin. However, there is a glaring deficit in the available data, emphasizing the need for additional robust studies to better delineate their effectiveness and implementation into surgical practice. The use of endovascular techniques continues to increase, thus limiting the number of open arterial procedures and the potential for further studies to be conducted. To provide the high-quality studies needed to better evaluate these prevention techniques, large multi-institutional collaboration will likely be necessary to provide the appropriate number of patients to evaluate true effectiveness.
