From anorectal varices is quite rare, but they can lead to a life-threatning hemorrhage because of their high flow rate and volume. Treatment of anorectal varices has not yet been established. We are able to control six cases of the varices by percutaneous transhepatic obliteration (PTO).

From 2004 to 2013, six patients (67-80 years old) who suffered anorectal varices induced by portal hypertension ware enrolled this study. All six women were treated with balloon-occluded antegrade transvenous sclerotherapy by 5% ethanolamine oleate iopamidole (EOI) via percutaneous transhepatic approach.

Four patients were successfully treated after one procedure, and one patient required twice treatment. In the case of rest one patient, the varices could be controlled by twice PTO and partial splenic embolization.

This study suggests that PTO by using EOI may be good treatment for anorectal varices.

Varices develop at any site of GI tract in patient with portal hypertension. Recently, the frequency of anorectal varices is reported as higher than before. bleeding from anorectal varices can lead to a life-threatning hemorrhage. No therapeutic strategy has yet been established. Our method using ethanolamine is effective treatment for anorectalvarices.
