十二指腸静脈瘤破裂に対して緊急BRTOを施行し，救命しえた1例

Duodenal varices are rare, but often life-threatening when ruptured. Treatments of ruptured duodenal varices have not been established, but in most cases, endoscopic injection sclerotherapy (EIS) is the first-line treatment. Interventional radiology including balloon-occluded retrograde transvenous obliteration (BRTO) has been reported as a useful therapy for duodenal varices following endoscopic therapy or natural hemostasis. Because drainage veins for duodenal varices are usually narrow and meandering, conventional BRTO tends to be difficult as an emergency therapy. Here we present a case of ruptured duodenal varices successfully treated by BRTO using a micro-balloon catheter.
