Gram-negative groin sepsis treated with covered stents and systemic antibiotics

Abstract

Prosthetic graft infections are hazardous conditions. Those due to Gram-negative bacteria are particularly serious. When Gram-negative microorganisms are present, entire graft excision is recommended, with revascularization if needed, preferably with autogenous tissues or with prosthetic grafts via non-infected planes if autogenous options are not available. We herein report the case of a diabetic man with critical limb ischemia, who after lower-extremity revascularization with a prosthetic graft, developed an early graft infection due to Gram-negative and fungal organisms, and who was successfully treated with a covered stent placed across grossly infected tissues. A discussion on the pertinent literature is also offered.
