Patient was admitted for outpatient interventional radiology (ir) for staged procedures.At the completion of the arteriogram, embolization prior to cryoablation, a small metallic foreign body was seen persisting in the region of intervention on review of imaging films.After cessation of the procedure, separate radiographs of the pelvis and right hip were obtained, as well as a focused ultrasound, demonstrating an apparent retained section of wire within the subcutaneous tissues, superficial to the right femoral artery and vein, and normal flow was established in the right common femoral artery and vein.Retrieval was felt to be more traumatic than the potential for complications, and therefore no retrieval attempt was made at the time.Subsequent attempt to remove the foreign body at a later date was unsuccessful.
