Patency of permanent vascular access creation in paediatric patients with end stage renal disease

Area of Science:

• Pediatric Nephrology
• Vascular Surgery
• Renal Replacement Therapy

Background:

• Renal transplant is the primary treatment for pediatric end-stage renal disease (ESRD).
• A significant percentage of pediatric ESRD patients require long-term hemodialysis due to donor scarcity.
• Permanent vascular access (PVA) is essential for effective long-term hemodialysis in children.

Purpose of the Study:

• To identify factors influencing the long-term patency of arteriovenous fistulas (AVFs) in pediatric patients.
• To evaluate the outcomes of AVF creation in children with prior indwelling catheters.
• To highlight considerations for the selection and timing of permanent vascular access in pediatric ESRD.

Main Methods:

• Observation of 5 children and 1 adolescent undergoing arteriovenous fistula creation.
• Discussion of influencing factors including body weight, vessel diameter, preoperative preparation, microsurgical technique, and postoperative care.
• Review of existing literature on pediatric vascular access.

Main Results:

• The study observed outcomes of AVF creation in a small cohort of pediatric patients.
• Key factors potentially impacting long-term AVF patency were identified and discussed.
• The importance of careful patient selection and surgical technique was implied.

Conclusions:

• Permanent vascular access, particularly AVFs, plays a critical role in managing pediatric end-stage renal disease.
• Optimizing factors such as patient characteristics and surgical approach is vital for successful long-term AVF function.
• Further research is needed to establish best practices for pediatric AVF creation and maintenance.
