The Marriage of Sartorius and Tensor Fasciae Latae in Treating Vascular Prosthetic Graft Infections

Background: Vascular prosthetic graft infection in the groin is associated with high morbidity and mortality. This article presents a case series on the use of 2 flaps in the treatment of this condition. Methods: Five patients, mean age 65 years (range, 49–74 years), with significant comorbidity were treated for an exposed and infected vascular prosthetic graft in the groin with a combination of sartorius muscle (SM) flap and tensor fascia lata (TFL) myocutaneous flap after debridement and start of microbiologic culture–guided antibiotic treatment. The SM flap was used to cover the exposed graft. To obtain stable wound coverage, the SM and remaining groin defect were closed with a pedicle TFL flap. Results: All flaps survived, with only 1 TFL flap suffering a small tip necrosis. All patients obtained stable wound coverage. Donor-site morbidity was minimal. During the follow-up, mean 46 months (range, 15–79 months), 1 patient had a recurrence after 15 months due to a kink in the elongated prosthetic graft that protruded through the skin alongside the SM and TFL flaps. Conclusions: The combination of SM and TFL flaps could be a new treatment option for patients who have an exposed and infected vascular prosthetic graft in the groin. This flap combination could also be used as a prophylactic procedure for those patients with a high risk to develop such a serious complication.
