Laparoscopic resection of idiopathic jejunal arteriovenous malformation after metallic coil embolization

Abstract

Background: Arteriovenous malformations (AVM) developed in the small intestine are rare, and it is sometimes difficult to identify and treat bleeding from small intestinal AVMs endoscopically because of their localization. We present a case of a jejunal AVM successfully treated with the combination of metallic coil embolization and laparoscopic surgery. Case presentation: A 50-year-old woman with a history of repetitive gastrointestinal bleeding was admitted to the hospital. Selective angiography revealed a jejunal AVM that was treated with metallic coil embolization. However, the lesion rebled 3 months later, and it was embolized again with metallic coils. Considering the risk of rebleeding, we performed laparoscopic resection of the jejunal AVM. Under laparoscopy alone, it was impossible to detect the lesion of the AVM. We used X-ray fluoroscopy intraoperatively to detect the metallic coils at the AVM. Partial resection of the jejunum with the AVM was performed followed by functional end-to-end anastomosis. The patient was discharged from the hospital without any complications after the surgery. Conclusions: The combination of metallic coil embolization by angiography and laparoscopic surgery with X-ray fluoroscopy can be effective for patients with repetitive bleeding from jejunal AVM.
