Management of refractory rectal variceal bleed using computed tomography.

Abstract

The management of refractory rectal variceal bleed using a minimally invasive percutaneous approach is described. Rectal varices are portosystemic collaterals that arise as a complication of portal hypertension. Bleeding is less common from rectal varices than from esophageal varices, but it is potentially life-threatening. Hence, it is of interest to describe a novel minimally invasive percutaneous technique to control refractory bleeding from rectal varices in a complex scenario where other proven treatments have failed. In the present study, a 28-year-old male presented to the Emergency department with one episode of hematemesis, hematochezia and severe abdominal pain. Sigmoidoscopy revealed actively bleeding rectal varices. CT abdominal angiogram revealed variceal formation in the rectum. we successfully performed CT guided percutaneous N- butyl cyanoacrylate (NBCA) glue injection of rectal varices with immediate and complete cessation of rectal bleed after failed endoscopic sclerotherapy.
