After femoral artery reconstructions, Groin wound complications are very fatal and difficult to treat. Long-term antibiotic medication, surgical debridement, and muscle flap covering are all effective methods. Our research analysed the effectiveness of a modified gracilis muscle flap (GMF) for covering up problems in the groyne area following synthetic graft artery bypass surgery. Methods: This was a prospective study. It included all individuals who had groyne infections after having synthetic grafts placed in their lower limb arteries that participants who underwent a GMF were considered in Damietta Faculty of medicine IRB – Al-Azhar University from May 2020 to May 2022 Results: according to Microbiology among the studied cases there were 48 (48%) Never cultured, 11 (11%) with enterococcus faecalis, 26 (26%) with pseudomonas and 15 (15%) with staphylococcus aureus, according to Successful treatment there were 15 (15%) failed and 85 (85%) succeeded, according to in-hospital death there were 5 (5%) died, according to complications there were 7 (7%) with anastomosis disruption, 2 (2%) with hematoma, 1 (1%) with necrosis of flap, 2 (2%) with persistent infection, 3 (3%) with sepsis and 5 (5%) with seroma. Conclusion: When difficulties arise in the groyne area following synthetic graft-based artery bypass surgery, GMS is a viable alternative for covering the exposed tissue. Gracilis muscle flap covering may be an effective alternative to total graft removal and extra-anatomic bypass in carefully chosen patients with vascular reconstructions and groyne infection. The procedure is straightforward, and the morbidity associated with gracilis muscle harvest is usually rather low.
