What is a transjugular intrahepatic portosystemic shunt (TIPS)?
A transjugular intrahepatic portosystemic shunt (TIPS) is an artificial connection that is created by a radiologist between two veins (hepatic vein and portal vein) in the liver. These veins are connected by a small tube known as a stent.
Why is the TIPS procedure done?
A transjugular intrahepatic portosystemic shunt (TIPS) procedure is used to treat the complications of portal hypertension that fail to respond to medicines. These complications are as follows:
- Variceal bleeding (bleeding from any of the veins that normally drain the digestive organs into the liver)
- Severe ascites (accumulation of fluid in the abdomen)
- Hepatic hydrothorax (fluid accumulation in the chest due to liver disease)
The TIPS procedure is also performed in patients
How does a transjugular intrahepatic portosystemic shunt (TIPS) work?
Blood from all the veins of the digestive system drains into the superior and inferior mesenteric veins; these two vessels are then joined by a splenic vein to form the portal vein. Thus, the portal vein carries blood from the digestive organs to the liver. Then, there are hepatic veins that carry blood away from the liver back to the heart.
Conditions such as liver cirrhosis increase the pressure in the portal veins, which puts back pressure in the veins of the digestive tract. This results in enlarged veins (engorged veins) that may lead to bleeding.
By creating a transjugular intrahepatic portosystemic shunt (TIPS), the blood flow from the enlarged veins of the digestive organs is redirected to the hepatic veins. This reduces the increased blood pressure in the portal veins and thus prevents subsequent complications.
How Is a Transjugular Intrahepatic Portosystemic Shunt (TIPS) Procedure Performed?
Before the procedure
- The doctor orders either ultrasonography (USG) report or computed tomography (CT) scan of the abdomen to check the status of the veins in the liver.
- The doctor instructs the patient to discontinue certain medicines for a few days before the procedure.
- The patient is asked not to eat or drink anything—except a few necessary medicines—for 8-12 hours before the procedure.
During the procedure
- The patient may be given a sedative medicine to make him relax during the procedure.
- The doctor inserts a flexible tube into the patient’s neck by making a small incision of ≤1 cm. On the end of this tube is a tiny balloon attached to a metal stent.
- Using a medical dye and an X-ray machine (fluoroscopy) that help in visualizing the internal structures, the doctor directs the tube into the portal vein.
- The balloon is inflated to fix the stent at an appropriate place in the vein. The patient may feel a little pain at this time.
- The doctor uses the stent to connect the portal vein to one of the three hepatic veins.
- The portal vein pressure is measured to check if it has been reduced with this procedure.
- The tube and balloon are then removed from the patient’s neck.
- After the procedure, the wound is cleaned and covered with a sterile bandage.
- The procedure is completed in about 60-90 minutes.
After the procedure
- The patient is monitored for a few hours. During this period, the patient’s head is kept elevated. Usually, they get discharged on the next day of the procedure.
- If there is significant bleeding, the patient is shifted to the intensive care unit (ICU) and discharged after a few days.
What are the complications of the TIPS procedure?
Possible risks associated with the transjugular intrahepatic portosystemic shunt (TIPS) procedure are as follows:
What is the recovery time for the TIPS procedure?
- The transjugular intrahepatic portosystemic shunt (TIPS) procedure is much safer than surgery, and its recovery period is fast. Most people recover well.
- The TIPS procedure improves the condition in about 80 to 90% of the patients with portal hypertension.
- Many people can resume their routine activities within 7-10 days.
- After a few weeks, the doctor will ask the patient for an ultrasonography (USG) report to check if the stent is working correctly.

Cirrhosis (Liver)Cirrhosis of the liver refers to a disease in which normal liver cells are replaced by scar tissue caused by alcohol and viral hepatitis B and C. This disease leads to abnormalities in the liver's ability to handle toxins and blood flow, causing internal bleeding, kidney failure, mental confusion, coma, body fluid accumulation, and frequent infections.
Symptoms include yellowing of the skin (jaundice), itching, and fatigue.
The prognosis is good for some people with cirrhosis of the liver, and the survival can be up to 12 years; however the life expectancy is about 6 months to 2 years for people with severe cirrhosis with major complications.
Drug-Induced Liver DiseaseDrug-induced liver diseases are diseases of the liver that are caused by:
- physician-prescribed medications,
- OTC medications,
- illicit (recreational) drugs, and
- environmental toxins.
Fatty Liver (NASH)Nonalcoholic fatty liver disease or NASH occurs due to the accumulation of abnormal amounts of fat within the liver. Fatty liver most likely caused by obesity and diabetes. Symptoms of fatty liver disease are primarily the complications of cirrhosis of the liver; and may include mental changes, liver cancer, the accumulation of fluid in the body (ascites, edema), and gastrointestinal bleeding. Treatment for fatty liver includes avoiding certain foods and alcohol. Exercise, weight loss, bariatric surgery, and liver transplantation are treatments for fatty liver disease.

How Is a Transjugular Liver Biopsy Done?A transjugular liver biopsy is an intravenous technique to obtain liver tissue sample for a biopsy. The doctor inserts the biopsy needle, covered in a thin, flexible sheath, through the jugular vein in the neck down into the liver’s primary vein (hepatic vein) to access the liver.
Liver (Anatomy and Function)The liver is the largest gland and organ in the body. There are a variety of liver diseases caused by liver inflammation, scarring of the liver, infection of the liver, gallstones, cancer, toxins, genetic diseases, and blood flow problems. Symptoms of liver disease generally do not occur until the liver disease is advanced. Some symptoms of liver disease include jaundice, nausea and vomiting, easy bruising, bleeding excessively, fatigue, weakness, weight loss, shortness of breath, leg swelling, impotence, and confusion. Treatment of diseases of the liver depends on the cause.
Liver BiopsyLiver biopsy is a procedure used to remove a small piece of liver tissue for examination for signs of disease or damage to the liver. Preparation for liver biopsy includes discontinuing certain medications. The techniques used to perform liver biopsy include percutaneous liver biopsy, transvenous liver biopsy, and laparoscopic liver biopsy. Recovery from liver biopsy are generally one to two days. Certain risks are associated with liver biopsy.
Liver DiseaseLiver disease can be cause by a variety of things including infection (hepatitis), diseases, for example, gallstones, high cholesterol or triglycerides, blood flow obstruction to the liver, and toxins (medications and chemicals).
