Glossary Entry: Hepatic Artery Catheter

Overview

Definition: A catheter specifically designed for insertion into the hepatic artery to deliver medications or contrast agents directly to the liver.

Detailed Description

Types and Variations

Variations: Different sizes and materials may be used for hepatic artery catheters, depending on the specific medical procedure or patient’s anatomy.

Indications

Common Uses: Hepatic artery catheters are commonly used in interventional radiology procedures, such as chemoembolization or radioembolization for liver cancer treatment.

Insertion and Placement

Procedure: The hepatic artery catheter is typically inserted using fluoroscopy guidance and may require the Seldinger technique for precise placement in the hepatic artery branches.

Clinical Considerations

Potential Complications

Risks: Potential complications of hepatic artery catheterization include bleeding, infection, vessel injury, or embolization of the catheter tip.

Care and Maintenance

Maintenance Requirements: Proper care and maintenance of the hepatic artery catheter include regular flushing to prevent occlusion and monitoring for signs of infection at the insertion site.

Additional Information

Related Devices

Associated Terms: Other related devices used in conjunction with hepatic artery catheters may include angiographic catheters, guidewires, and contrast agents.

Innovations and Advancements

Recent Developments: Recent advancements in hepatic artery catheter technology include the development of catheters with improved flexibility and trackability for easier navigation in the hepatic vasculature.

Regulatory and Safety Notes

Regulations: Hepatic artery catheters are regulated medical devices that must meet specific safety and performance standards set by regulatory authorities.
