Description
A 73-year-old man with liver cirrhosis due to hepatitis C virus infection was admitted to our hospital because of massive bleeding from external varices. Colonoscopic examination revealed that giant anorectal varices had developed between the anus and rectal ampulla, and had ruptured at the perianal site. On three-dimensional computed tomography imaging, the feeding and drainage vessels of the varices were identified as the inferior mesenteric vein and right inferior hemorrhoidal vein, respectively. Endoscopic therapies were not employed for the bleeding varices, because the blood flow volume of the feeding vessel was extremely large. Balloon-occluded retrograde transvenous obliteration (B-RTO) was therefore carried out through the drainage vessels. The variceal blood flow disappeared after B-RTO therapy, and the varices decreased in size with thrombus formation verified by colonoscopy. Bleeding from the external varices also ceased. B-RTO therapy may be an effective approach for giant anorectal varices presenting as a complication in liver cirrhosis patients in whom the main drainage vessels can be determined.
