Summary
Creating effective vascular access for chronic hemodialysis remains a challenge. Direct arteriovenous (AV) fistulas are the preferred method due to superior patency and fewer complications, with alternatives used sequentially.
Area of Science:
- Nephrology
- Vascular Surgery
- Dialysis Access
Background:
- Vascular access is a critical and persistent challenge in chronic hemodialysis for both healthcare providers and patients.
- Ensuring adequate and long-lasting access is essential for effective treatment delivery.
Purpose of the Study:
- To review and recommend optimal strategies for establishing and managing vascular access for chronic hemodialysis.
- To compare the efficacy of different types of vascular access, prioritizing autologous options.
Main Methods:
- Review of established vascular access techniques, including direct arteriovenous (AV) fistulas and AV grafts.
- Evaluation of surgical approaches, from distal to proximal sites, including Brescia-Cimino and brachiocephalic fistulas.
- Assessment of alternative options like snuff-box fistulas and transposed basilic vein fistulas.
Main Results:
- Direct AV fistulas demonstrate the highest patency rates and lowest complication rates, making them the preferred choice.
- A stepwise approach, starting with distal autologous options and progressing proximally, is recommended.
- Graft fistulas, particularly those made of ePTFE, are a viable alternative but are associated with higher costs and should be reserved for cases where autologous options are exhausted.
Conclusions:
- Direct AV fistulas are the gold standard for chronic hemodialysis vascular access.
- A strategic, stepwise implementation of various autologous access methods is crucial for long-term patient management.
- Graft fistulas serve as a secondary option, with ePTFE grafts offering comparable patency to autologous fistulas at a greater expense.
