First report of an ilio-popliteal bypass through the greater sciatic foramen. Case report

A 47 year-old man, who had a history of pelvic radiotherapy for the treatment of testicular tumour 30 years ago, was referred with minor tissue loss of the right lower extremity, grade III, category 5 of the Rutherford classification. His groin region presented with severe radiation damage. Arteriography demonstrated the occlusion of external iliac and femoral arteries. Revascula-risation was performed in the lateral decubitus position, with a ringed polytetrafluoroethylene (PTFE) graft bypass between normal common iliac and popliteal arteries through the greater sciatic foramen. Quick healing was observed. Patient is well 6 months postoperatively. Immediate and 6 month postoperative imaging demonstrated the good patency of the graft. A duplex ultrasound performed 6 month postoperatively showed no significant compression while the patient was in the sitting position.
