OBJECTIVE: We aimed to evaluate the safety and efficacy of embolization using a 1.7-Fr catheter and soft bare coil to treat acute small intestinal bleeding. MATERIAL AND METHODS: Subjects were five consecutive patients who experienced onset of melena with small intestinal bleeding and underwent transcatheter arterial embolization with 1.7-Fr catheters and 0.010-inch detachable bare coils (five procedures in total). Technical success, clinical success, relative post-procedural complications, arterial bleeding source and cause, and relationship between coagulopathy and embolization efficacy were examined by capsule endoscopy. RESULTS: We achieved 100% technical and clinical success for the five transcatheter arterial embolizations. All catheterizations of the vasa recta of the bleeding artery (jejunal artery, n = 2; ileal artery, n = 3) were possible with a 1.7-Fr catheter. We achieved high embolization efficacy in two patients with coagulopathy. No rebleeding, intestinal ischemia, or necrosis was observed on follow-up capsule endoscopy. We confirmed that peptic ulcers/ulcer scars were the cause of bleeding for all patients. CONCLUSION: Embolization with 0.010-inch coils using a 1.7-Fr catheter and catheterization of the vasa recta of bleeding vessels was effective and safe for treating small intestinal bleeding.
