Retained foreign body in radial artery: Endovascular retrieval and salvage of a hemodialysis arteriovenous fistula

A foreign body was inadvertently retained in the patient's radial artery during a previous endovascular procedure, leading to early recurrent thrombosis of his hemodialysis arteriovenous fistula. Through the strategic use of ultrasound, a through-and-through wire, as well as sequential balloon inflation to "push" the foreign body, it was successfully retrieved endovascularly, leading to effective salvage of the patient's hemodialysis access.
