Other infection risk factors		Gangrenous cholecystitis  Bowel ischemia	Urostomy  Multiple recent femoral revisions	Multiple open thrombectomies of prior fem-pop bypass	Colostomy midline abscess ex-lap for SBO	Aortoenteric fistula  Thrombectomy of RLE 24 h after ax-fem
Signs and symptoms	Abdominal and back pain  No fevers, leukocytosis, or bacteremia	Abdominal pain, sepsis, leukocytosis, lactic acidosis, bowel ischemia	Fevers and chills, erythema and purulent drainage from right groin	Left groin erythema and purulent drainage  No fevers, leukocytosis, or bacteremia	Right groin erythema and pain  No fevers, leukocyteosis, or bacteremia	Right groin erythema and purulent drainage  No fevers, leukocytosis, or bacteremia
Diagnosis	CT scan: fluid collection at all anastomoses	Ex lap: thrombosed graft with purulence	CT scan: fluid surrounding R femoral artery/fem–fem anastomosis	Clinical exam	CT scan: fluid collection surrounding bypass graft	CT scan: fluid and air around right femoral anastomosis
