Infected Groin (Graft/Patch): Managed with Sartorious Muscle Flap.

Purpose: The purpose of this study was to review the natural history, clinical outcome and safety in patients undergoing sartorius muscle flap (SMF) for groin infection, including lymphocele.

Materials And Methods: We retrospectively reviewed the records of patients who underwent SMF in a single center between 2000 and 2009.

Results: Thirty patients (17 male, 13 female) underwent SMF for groin infection, which included infections of 22 artificial femoral bypass grafts (including 2 cryoveins) and 5 common femoral patch grafts, and 3 lymphocele infections (2 cardiac catheterizations and 1 penile cancer lymph node dissection). Wound isolates were most commonly Gram-positive organisms (n=22) with Gram-negative isolates and mixed infections accounting for 4 and 3 cases, respectively. In 9 patients there was no growth of organisms. Adjunctive wound vacuum-asssisted wound closure therapy was performed in 18 patients. Follow-up duration ranged from 8 days to 56 months (mean 14.1 months) after SMF. Reoperation was performed in 3 patients due to wound bleeding (n=1) and reinfection (n=1). One patient underwent graft excision with external bypass operation. There was 1 mortality case due to sepsis during the study period.

Conclusion: We found that muscle flap surgery provides successful single-intervention therapy for groin infections including lymphocele. Graft ligation or aggressive excision with bypass surgery should be reserved for patients requiring rapid control of sepsis for lifesaving.
