Hemodialysis vascular access: everything you always wanted to know about it (but were afraid to ask)

Area of Science:

• Nephrology
• Vascular Surgery
• Public Health

Background:

• Effective dialysis treatment relies heavily on appropriate vascular access.
• Options include arteriovenous fistulas, grafts, and central venous catheters, each with distinct advantages and disadvantages.
• Vascular access complications and costs vary significantly among the different types.

Purpose of the Study:

• To review the prevalence of various vascular access types for dialysis.
• To analyze the benefits and complications associated with each access method.
• To discuss recent findings and trends in dialysis vascular access.

Main Methods:

• Literature review of recent studies on dialysis vascular access.
• Comparative analysis of arteriovenous fistulas, grafts, and central venous catheters.
• Examination of epidemiological data on vascular access utilization.

Main Results:

• Arteriovenous fistulas are generally considered the optimal choice due to a favorable balance of benefits and complications.
• There is a concerning increase in the use of central venous catheters for initiating dialysis, even in developed nations.
• Prevalence of arteriovenous fistulas remains lower in the United States compared to Europe.

Conclusions:

• Despite the superiority of arteriovenous fistulas, their uptake is suboptimal.
• The rising trend of central venous catheter use highlights challenges in vascular access planning and execution.
• Nephrologists increasingly require interventional skills to maintain vascular access patency.
