Role of interventional radiology in intractable bleeding rectal varices.

In the setting of portal hypertension, intractable bleeding from anorectal varices is a rare occurrence. In this review, clinical presentation and management of this dilemma are presented in a case-based fashion. Bleeding may occur in the absence of prior history of cirrhosis or gastroesophageal varices and measurement of hepatic venous pressure gradient and liver biopsy could help to establish the diagnosis.
