We describe a patient with a fistula between small bowel and a polyester patch of the common iliac artery. After emergency treatment with an endograft, the patch was replaced by a venous patch. Within 3-week a symptomatic pseudoaneurysm developed. It was decided to embolize the pseudoaneurysm using autologous subcutaneous fat, followed by a femoro-femoral crossover bypass using an allograft. Using this technique, the pseudoaneurysm was successfully excluded. This case shows that subcutaneous fat tissue can be used as an autologous embolic material, also in larger vessel pathology and in cases of ongoing infection, where regular embolization material cannot be used.
