Background Infection of leg wounds is a common complication following great saphenous vein harvesting (GSV) for coronary bypass grafting (CABG). This complication can result in increased risk of patient morbidity and mortality by causing septicemia, and gangrene, subjecting the patients to amputation. This study aimed to assess the efficacy of negative pressure wound therapy (NPWT) compared to conventional wound care in infected leg wounds following GSV harvesting for myocardial revascularization. Results The NPWT group had a significantly lower rate of deep vein thrombosis (p = 0.013), osteomyelitis (p < 0.001), bed sores (p < 0.001), shorter duration of tissue edema (p < 0.001), and lesser discharge (p < 0.001). Also, the length of hospital stay was significantly shorter in the NPWT group (p < 0.001). Multivariable analysis revealed that traditional wound care (without NPWT, p < 0.001) and wound stage IV (p = 0.001) significantly and independently prolonged the length of hospital stay. Conclusions The use of NPWT in advanced complicated infected leg wounds could improve patients’ outcomes and satisfaction by decreasing the rate of complications and the length of hospital stay.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
