Glossary Entry: Arteriovenous Fistula Needle


Definition: The arteriovenous fistula needle is a specialized medical device used for accessing an arteriovenous fistula, a surgically created connection between an artery and a vein. This needle is specifically designed for the purpose of hemodialysis and is essential for the successful creation of vascular access for this procedure.

Detailed Description

Types and Variations

Variations: Arteriovenous fistula needles come in various sizes and designs, with straight or curved configurations to accommodate different patient anatomies and vascular access sites. Some needles may have safety features to prevent accidental needlesticks.


Common Uses: The arteriovenous fistula needle is commonly used in hemodialysis procedures, allowing for the withdrawal of blood from the patient’s body, its filtration through a dialysis machine, and the return of filtered blood back into the patient’s bloodstream.

Insertion and Placement

Procedure: The insertion and placement of the arteriovenous fistula needle require careful attention to avoid injury to the vascular access. Healthcare professionals need to follow specific guidelines and techniques recommended for safe and effective placement, such as the use of the rope-ladder technique and proper taping and securing of the needle.

Clinical Considerations

Potential Complications

Risks: Potential risks associated with the use of the arteriovenous fistula needle include infection, bleeding, hematoma formation, infiltration, and dislodgement. Healthcare providers must monitor for these complications during and after the insertion of the needle.

Care and Maintenance

Maintenance Requirements: Proper care and maintenance of the arteriovenous fistula needle involve regular inspection for damage or wear, ensuring cleanliness and sterility, and prompt replacement when necessary to prevent adverse events during hemodialysis.

Additional Information

Related Devices

Associated Terms: Related devices or accessories used in conjunction with the arteriovenous fistula needle may include antiseptic solutions, sterile drapes, tourniquets, and adhesive dressings for vascular access site care.

Innovations and Advancements

Recent Developments: Recent advancements in arteriovenous fistula needle technology have focused on enhancing needle safety features, improving needle visualization during insertion, and reducing the risk of complications through innovative needle design and materials.

Regulatory and Safety Notes

Regulations: Regulatory considerations for the use of arteriovenous fistula needles involve adherence to standards for medical device safety, infection control, and quality management to ensure patient safety and optimal hemodialysis outcomes.
