BRTO procedure

BRTO (Balloon-Occluded Retrograde Transvenous Obliteration) is a procedure used to treat bleeding abdominal vessels, specifically those associated with a condition called gastric varices.

During a BRTO procedure, the patient is typically positioned lying down. A catheter is inserted into a vein, usually in the groin area, and guided through the venous system to the site of the bleeding abdominal vessels.

Once the catheter is positioned near the bleeding vessels, a balloon is inflated to temporarily occlude the blood flow in the vein supplying the varices. This occlusion redirects the blood flow towards alternative venous pathways.

After the balloon is inflated, a sclerosing agent, such as ethanol or sodium tetradecyl sulfate, is injected into the varices through the catheter. The sclerosing agent causes the varices to shrink and close off, stopping the bleeding.

Following the injection, the balloon is deflated, and the catheter is removed. The procedure is usually performed under X-ray guidance to ensure proper catheter placement and to monitor the progress of the sclerosing agent injection.

BRTO is an effective method for controlling bleeding from gastric varices, which are dilated veins in the stomach caused by portal hypertension. Portal hypertension is often associated with liver cirrhosis or other liver diseases that cause increased pressure in the portal vein system.

By occluding the blood flow in the vein supplying the varices and injecting a sclerosing agent, BRTO helps to prevent recurrent bleeding episodes and manage the underlying condition.

In summary, the BRTO procedure is used to treat bleeding abdominal vessels, specifically gastric varices associated with portal hypertension. It involves temporarily blocking the blood flow in the vein supplying the varices, followed by the injection of a sclerosing agent to close off the varices and stop the bleeding.
