Glossary Entry: Transhepatic Biliary Drainage Catheter

Overview

Definition: A catheter used to drain bile from the liver when the bile ducts are blocked or narrowed, typically inserted through the skin and into the liver to allow for the drainage of bile into an external collection bag.

Detailed Description

Types and Variations

Variations: Different sizes and designs of transhepatic biliary drainage catheters may be used depending on the specific patient’s anatomy and the nature of the biliary blockage.

Indications

Common Uses: This catheter is commonly used in patients with obstructive jaundice, bile duct tumors, or other conditions that cause blockages in the bile ducts.

Insertion and Placement

Procedure: The catheter is inserted under imaging guidance, typically using the Seldinger technique to access the biliary system and allow for the placement of the catheter into the liver.

Clinical Considerations

Potential Complications

Risks: Potential complications of transhepatic biliary drainage catheter placement include infection, bleeding, bile leakage, and catheter dislodgement.

Care and Maintenance

Maintenance Requirements: Proper care and maintenance of the catheter include regular flushing, monitoring for signs of infection, and ensuring proper drainage function.
