We Refuse to Give up on Nonmaturing Fistulas

Area of Science:

• Nephrology
• Vascular Surgery
• Dialysis Access

Background:

• Nonmaturing arteriovenous fistulas (AVFs) present significant challenges in hemodialysis.
• AVF nonmaturation increases reliance on central venous catheters (CVCs), associated with higher morbidity and mortality.
• Effective access planning is essential to mitigate AVF nonmaturation.

Purpose of the Study:

• To outline strategies for managing nonmaturing arteriovenous fistulas.
• To emphasize the importance of timely AVF evaluation and salvage.
• To guide clinical decision-making regarding the persistence with nonmaturing AVFs versus CVC use.

Main Methods:

• Review of current practices and literature regarding AVF maturation and salvage.
• Clinical assessment of AVFs at 4-6 weeks post-creation.
• Consideration of procedural history and long-term success probabilities.

Main Results:

• Early identification of nonmaturing AVFs is critical.
• Salvage interventions should be considered but have limitations.
• Prolonged salvage efforts may increase risks and decrease long-term success.

Conclusions:

• A strategic approach to AVF access planning is necessary.
• Timely evaluation and judicious salvage attempts are recommended.
• Discontinuation of nonmaturing AVF salvage may be optimal for patient outcomes in certain scenarios.
