Balloon-occluded Retrograde Transvenous Obliteration (BRTO)
What is BRTO?
Balloon-occluded Retrograde Transvenous Obliteration (BRTO) is a minimally invasive procedure used to treat gastric varices (enlarged veins in the stomach) that can bleed. This procedure is designed to close off the abnormal veins that are causing the bleeding and prevent further complications.
BRTO involves the use of a balloon catheter that is inserted into the veins through a small incision, often in the groin or neck. Once the balloon is inflated, it blocks the abnormal veins, and a special substance is injected to obliterate them, stopping the bleeding.
Why is BRTO Needed?
BRTO is typically used in patients who have gastric varices, which may result from portal hypertension (high blood pressure in the veins that carry blood from the intestines to the liver). The pressure buildup can cause veins in the stomach to enlarge, and they may eventually rupture, leading to life-threatening bleeding.
The BRTO procedure helps to prevent or control bleeding in these veins, especially when other treatments have not been effective.
What Happens During the BRTO Procedure?
Here's what you can expect during the BRTO procedure:
1. Preparation:
- Before the procedure, your doctor will explain the steps and answer any questions. You may be asked to fast for several hours prior to the procedure. Blood tests and imaging studies (such as ultrasound or CT scans) may be done to evaluate your condition.
- You will receive local anesthesia to numb the area where the catheter will be inserted, and you may also receive sedation to help you relax during the procedure.
2. Catheter Insertion:
- A small incision is made in the groin or neck, where a catheter is inserted into a vein.
- The catheter is carefully guided to the area where the abnormal veins (gastric varices) are located, with the help of fluoroscopy (real-time X-ray imaging).
3. Balloon Occlusion:
- Once the catheter is in place, a small balloon is inflated inside the vein to temporarily block blood flow to the varices. This step allows the doctor to inject a special substance that will seal off the abnormal veins.
4. Obliteration of Veins:
- After the balloon is inflated, a sclerosing agent (a substance that causes the blood vessels to close) is injected into the veins, obliterating them and preventing further bleeding.
5. Completion:
- The balloon is deflated, and the catheter is removed. The small incision site will be bandaged.
- The procedure usually takes about 1-2 hours, depending on the complexity.

After the Procedure
Recovery:
- After the procedure, you will be monitored for a short time to make sure there are no immediate complications.
- Most patients will stay in the hospital for 24-48 hours for observation.
Activity:
- Rest is recommended for the first few days after the procedure. Your doctor will provide guidelines on when you can resume normal activities.
Follow-up Care:
- Your doctor will schedule follow-up visits to monitor the success of the procedure and to make sure that the gastric varices do not return.
- Imaging studies will be used to evaluate the treated area and ensure the veins remain closed.
Possible Risks and Complications
While BRTO is generally safe, as with any procedure, there are risks involved. These may include:
- Infection at the incision site.
- Bleeding at the site of the catheter insertion or internally.
- Damage to nearby structures (such as the liver or other blood vessels).
- Blood clots (rare, but possible).
- Contrast dye reaction (allergic reactions to the dye used for imaging).
- Failure to obliterate all the varices, which may require additional procedures.
What to Expect After BRTO
Symptom Improvement:
- The goal of BRTO is to stop or reduce the risk of bleeding from gastric varices. After the procedure, you should notice an improvement in symptoms such as stomach pain or bleeding. If you experienced any previous bleeding episodes, the risk of future bleeding should be significantly reduced.
Diet and Lifestyle:
- After the procedure, your doctor may provide guidelines on your diet or medications to help manage your condition and prevent further complications.
- Avoid activities that may strain the area of the catheter insertion until you are fully healed.
Monitor for Complications:
- It's important to watch for any signs of complications such as pain, swelling, or fever. Contact your healthcare provider immediately if you experience any of these symptoms.
When to Contact Your Doctor
Call your doctor or seek immediate medical attention if you notice any of the following:
- Severe pain or swelling in the groin or neck area.
- Fever or signs of infection at the catheter insertion site.
- Abdominal pain, vomiting, or black stools (signs of bleeding).
- Blood in urine
- Difficulty breathing or chest pain.
Conclusion
BRTO is an effective, minimally invasive treatment for gastric varices and the complications of portal hypertension. By closing off the enlarged veins, this procedure can prevent life-threatening bleeding and improve your overall health.
It is important to follow all post-procedure instructions, attend follow-up appointments, and contact your doctor if you experience any concerning symptoms.
If you have any questions about the procedure or would like more information, please contact your healthcare provider. They will guide you through the process and ensure you understand all aspects of your treatment.
