Introduction
A liver biopsy is a medical procedure where a small amount of liver tissue is removed for analysis. The tissue sample is typically examined under a microscope to diagnose liver diseases such as hepatitis, cirrhosis, or liver cancer. The jugular vein in the neck carries blood from the head and neck back to the heart. There are two jugular veins in the body, the internal and external jugular veins, which can be used for medical procedures such as a transjugular liver biopsy. Transjugular liver biopsy is a minimally invasive medical procedure that involves the insertion of a needle into the liver through the jugular vein. This procedure aims to obtain a small sample of liver tissue for further examination and analysis. The procedure is usually performed on patients with liver disease, providing doctors with valuable information about the liver's health and function. An interventional radiologist typically performs the transjugular liver biopsy procedure.
What Are the Indications of Transjugular Liver Biopsy Procedure?
Transjugular liver biopsy is typically performed on patients with or suspected liver disease. A doctor may recommend it in the following circumstances:
-
Diagnosis of Liver Disease: If a patient is showing symptoms of liver disease, such as jaundice, fatigue, or abdominal pain, a transjugular liver biopsy may be recommended to determine the cause of the symptoms. Liver disease can have various causes, such as hepatitis, cirrhosis, or fatty liver disease, and a biopsy can help identify the specific type of liver disease and guide treatment options.
-
Monitoring Liver Disease Progression: Patients diagnosed with liver disease may need periodic biopsies to monitor the disease's progression and assess the treatment's effectiveness. A transjugular liver biopsy may be preferred in some cases over a traditional biopsy, as it can be performed on patients with coagulation disorders or ascites, a condition in which fluid accumulates in the abdomen.
-
Evaluation of Liver Transplant Candidates: Patients being evaluated for a liver transplant may need a biopsy to assess the severity of their liver disease and determine if a transplant is necessary. A transjugular liver biopsy may be preferred in these cases as it can be performed on patients with advanced liver disease who may have a higher risk of complications with a traditional biopsy.
-
Diagnosis of Non-liver Diseases: In rare cases, a transjugular liver biopsy may be performed to diagnose non-liver diseases that can affect the liver, such as lymphoma or sarcoidosis.
What Are the Preoperative Preparation Before Transjugular Liver Biopsy Procedure?
Before undergoing a transjugular liver biopsy, there are several steps that a patient may need to take to prepare for the procedure. These may include:
-
The patient may need to stop taking certain medications or supplements that affect blood clotting, including Aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), and blood thinners. The patient should discuss any medications or supplements they take with their doctor before the procedure.
-
The patient may need to fast for several hours before the procedure, typically for at least 6 hours. This is to reduce the risk of complications during the procedure.
-
The doctor reviews the patient's medical history, including previous surgeries or procedures, allergies, and current medical conditions.
-
The patient must have blood tests before the procedure to assess liver function and clotting ability.
-
The patient may need to undergo imaging tests, including an ultrasound or CT (computed tomography) scan, to assess the location and condition of the liver and surrounding structures.
-
The patient will need to sign a consent form indicating that a person understands the risks and benefits associated with the procedure and has had their questions answered.
What Is the Procedure of Transjugular Liver Biopsy Procedure?
The transjugular liver biopsy procedure is typically performed in a hospital or outpatient setting and may take up to an hour to complete. The following steps outline the general procedure:
-
Preparation: The patient will be positioned on an X-ray table with their back table, and local anesthesia will be given to numb the area where the needle will be inserted. The doctor may also administer a mild sedative to help the patient relax.
-
Insertion of the Catheter: The doctor will make a small incision in the neck and insert a thin, flexible tube called a catheter into the jugular vein. X-ray guidance guides the catheter through the vein and into the liver.
-
Liver Imaging: Once the catheter is in place, the doctor injects a contrasting dye into the catheter to help visualize the liver and surrounding structures using X-ray imaging.
-
Biopsy: The doctor will use a special needle, called a biopsy needle, to obtain a small sample of liver tissue. The needle is inserted through the catheter and into the liver. Once the needle is in place, the doctor will quickly remove a small tissue sample. The needle may be used to obtain multiple samples from different areas of the liver.
-
Post-Procedure Care: After the biopsy, pressure will be given to the biopsy area to help stop bleeding. The patient will be monitored for some time to ensure no complications. Once the patient becomes stable, they are allowed to go home. The doctor may provide instructions on post-procedure care, such as avoiding strenuous activities and taking pain medication if necessary.
What Are the Complications of Transjugular Liver Biopsy Procedure?
After a transjugular liver biopsy, patients typically need to rest for several hours and be monitored for potential complications. Here are some of the common post-operative considerations:
-
Monitoring: The patient may be monitored for several hours after the procedure to ensure no complications, such as bleeding, infection, or changes in vital signs. The doctor may also order blood tests to monitor liver function and clotting ability.
-
Pain Management: The patient may experience discomfort or pain at the biopsy site or the neck where the catheter was inserted. Over-the-counter pain medications, such as acetaminophen, may be recommended for pain relief.
-
Activity Restrictions: The patient may need to avoid strenuous activity and heavy lifting for some time after the procedure, which reduces the risk of bleeding or injury at the biopsy site.
-
Follow-up Appointments: The doctor may schedule a follow-up appointment to review the biopsy results and discuss any further treatment options.

Conclusion
The transjugular liver biopsy procedure is a safer alternative to percutaneous liver biopsies, particularly for patients with coagulation disorders or ascites. It offers improved access, increased success rates, and the ability to evaluate portal hypertension. While risks exist, careful patient selection and monitoring help mitigate these concerns, making transjugular liver biopsy a valuable diagnostic and therapeutic tool in managing liver diseases.
