Iatrogenic foreign bodies are a challenging complication to both the interventional radiologist and patient, resulting in impaired quality of life and substantial financial cost. The case report describes a successful percutaneous transhepatic removal of an intra-abdominal foreign body. A 72-year-old man underwent surgery for placement of a retrievable covered stent for refractory bile leakage after left hemihepatectomy. Three days after placement, stent folding and migration into a chronic biloma cavity occurred via the bile leakage site. By using a balloon catheter technique, the folded stent could be straightened and repositioned into the bile duct to minimize stent-strut injury during retrieval. The interventional approach could be a valid treatment option for intra-abdominal foreign bodies, as well as intravascular foreign bodies. A thorough understanding of devices and techniques can provide the interventional radiologist with valuable information regarding procedural planning and the management of iatrogenic foreign bodies.
