Systemic Effects of Hemodialysis Access

Area of Science:

• Nephrology
• Cardiovascular Medicine
• Vascular Surgery

Background:

• Patients with advanced chronic kidney disease, especially end-stage renal disease, face high cardiovascular event risks.
• Vascular access complications significantly contribute to morbidity and mortality in this population.
• Arteriovenous access is preferred over catheters for hemodialysis due to lower infection rates, fewer interventions, and improved survival.

Purpose of the Study:

• To review the short- and long-term effects of dialysis access on cardiovascular, neurohormonal, and pulmonary systems.
• To examine the impact of dialysis access on survival in patients undergoing hemodialysis.
• To highlight the importance of individualizing vascular access and kidney replacement therapy choices based on patient comorbidities.

Main Methods:

• Literature review of studies examining the physiological impacts of dialysis access.
• Analysis of cardiovascular, neurohormonal, and pulmonary system responses to arteriovenous access.
• Evaluation of survival data comparing different dialysis access modalities.

Main Results:

• Arteriovenous access creation initiates complex cardiovascular and neurohormonal changes, with both beneficial and detrimental effects.
• The choice of vascular access influences patient outcomes, including survival and complication rates.
• Comorbidities significantly modify the impact of dialysis access, necessitating personalized management strategies.

Conclusions:

• Dialysis access profoundly affects multiple organ systems and overall survival in chronic kidney disease patients.
• Individualized selection of vascular access and dialysis modality is essential, considering patient-specific factors and comorbidities.
• Further research is needed to optimize the management of dialysis access to mitigate negative impacts and enhance patient outcomes.
