Coil Migration Following Transcatheter Arterial Embolization

Abstract

A 69-year-old man presented with hypovolemic shock caused by massive gastrointestinal bleeding. Angiography revealed active bleeding in a branch of the gastroduodenal artery (Picture 1a). The patient underwent emergent transcatheter arterial embolization (TAE), and angiography confirmed complete occlusion due to bleeding (Picture 1b). The patient's condition rapidly stabilized; however, esophagogastroduodenoscopy performed seven days after TAE showed the presence of duodenal ulcers and a metal material impacted in the duodenal surface (Picture 2). Coil migration was highly suspected. We prescribed conservative management, and the patient was discharged after an uneventful hospital stay. No more bleeding episodes or additional sequelae were observed over the following months.The standard treatment for upper gastrointestinal bleeding

Endovascular Coil Migration Into the Intestinal Lumen: Two Cases of Successful Nonoperative Management

“…Shen et al noted no complications approximately 2 months after presentation of coil erosion without surgical or endoscopic intervention. 10 Cases have also reported the coil passing per rectum without complication, which is the likely result of our second case. 5 The number of migrated coils that pass without being detected is unknown as asymptomatic patients are not likely to present and there is no standard follow-up as coils are placed in a wide range of clinical settings.…”
