Hospital Clínic Hepatic Hemodynamics: TIPS technique

Introduction

This tutorial provides a step-by-step guide on the TIPS (Transjugular Intrahepatic Portosystemic Shunt) technique used in hepatic hemodynamics, as introduced by Dr. Joan Carles García-Pagán from the Hospital Clínic de Barcelona. The TIPS procedure is crucial for managing portal hypertension and related complications. This guide outlines the key steps and considerations for performing this technique effectively based on extensive clinical experience.

Step 1: Understanding the Indications for TIPS

Before proceeding with the TIPS procedure, it's essential to identify the appropriate indications, which include:

• Portal hypertension due to cirrhosis
• Refractory ascites
• Bleeding esophageal varices
• Hepatic encephalopathy

Practical Advice:

• Conduct a thorough patient assessment to determine if TIPS is suitable.
• Discuss the risks and benefits with the patient and their family.

Step 2: Preparing for the Procedure

Preparation is crucial for a successful TIPS procedure. Follow these steps:

1. Pre-procedural Imaging:

   • Perform imaging studies such as ultrasound or CT scans to evaluate the hepatic and portal veins.

2. Laboratory Tests:

   • Ensure liver function tests, coagulation profile, and renal function are reviewed.

3. Consent:

   • Obtain informed consent from the patient, explaining the procedure, risks, and expected outcomes.

Practical Advice:

• Ensure that all necessary equipment and instruments are available before beginning the procedure.

Step 3: Performing the TIPS Procedure

The TIPS procedure involves several key steps:

1. Accessing the Jugular Vein:

   • Use a catheter to access the internal jugular vein, typically under ultrasound guidance.

2. Catheter Placement:

   • Advance a catheter into the hepatic vein, ensuring proper positioning.

3. Creating the Shunt:

   • Utilize a needle to create a tract between the hepatic vein and the portal vein.
   • Insert a stent to maintain patency.

4. Post-Procedure Imaging:

   • Perform imaging to confirm the placement of the shunt and assess for complications.

Common Pitfalls to Avoid:

• Ensure careful monitoring of the patient's vital signs throughout the procedure.
• Be cautious of potential complications such as bleeding or infection.

Step 4: Post-Procedure Care and Follow-Up

After the TIPS procedure, follow these guidelines for patient care:

1. Monitoring:

   • Monitor the patient in a recovery area for at least 24 hours post-procedure.

2. Assessing Complications:

   • Watch for signs of hepatic encephalopathy, bleeding, or shunt dysfunction.

3. Long-Term Management:

   • Schedule follow-up appointments to monitor liver function and shunt patency.

Practical Advice:

• Educate patients on lifestyle modifications that may improve outcomes, such as dietary changes and avoiding alcohol.

Conclusion

The TIPS technique is a vital intervention for managing complications related to portal hypertension. By following these structured steps—from understanding indications and preparing for the procedure to performing TIPS and ensuring post-procedure care—you can improve patient outcomes significantly. Always stay updated on best practices and emerging techniques in this field for continuous improvement in care delivery.
