# A Case of Coil-Assisted Retrograde Transvenous Obliteration to Treat Colonic Varices

## TL;DR

This paper presents a case where a rare and life-threatening colonic variceal bleeding was successfully treated using a specific interventional technique.

## Contribution

The paper contributes a new case demonstrating the effectiveness of CARTO in treating colonic variceal bleeding, a rare condition with limited treatment evidence.

## Key findings

- CARTO was successfully used to treat colonic variceal bleeding in a patient.
- The case adds to the limited evidence supporting CARTO's efficacy for non-esophageal variceal bleeding.
- This approach may offer a viable treatment option for a rare and high-risk condition.

## Abstract

Colonic variceal bleeding is a rare cause of lower gastrointestinal (GI) bleeding, which carries a high mortality rate. Due to limited data, the optimal management of colonic variceal bleeding is not known. Coil-assisted retrograde transvenous obliteration (CARTO) has been shown to be very effective in managing non-esophageal variceal bleeding, but only a few cases demonstrate its effectiveness in treating colonic variceal bleeding. Here we present a case of colonic variceal bleeding treated with CARTO in order to expand on the limited body of evidence showing its efficacy in effectively treating this rare cause of life-threatening GI bleeding.
