title: Late-onset colonic occlusion after emergent selective embolization of sigmoid artery with N-butyl cyanoacrylate for life-threatening traumatic bleeding.
abstract: A 30-year-old man who had life-threatening traumatic bleeding from the sigmoid colon was successfully treated with emergent selective embolization of the sigmoid artery with N-butyl cyanoacrylate without ischemia. However, the patient developed colonic occlusion that became clinically apparent 6 months after the embolization and required surgical treatment. Interventional radiologists should be aware of the possibility of late-onset intestinal stricture. Because complications of mesenteric artery embolization may be delayed for months, an extended follow-up period is prudent to monitor the embolization site even in the absence of clinical symptoms.
