Complications of vascular access for hemodialysis
Insights
Primary arteriovenous fistula (AVF) is the best choice for long-term hemodialysis access. AVFs offer superior patency and fewer complications compared to synthetic grafts, improving patient outcomes in end-stage renal disease.
Area of Science:
- Nephrology
- Vascular Surgery
- Medical Devices
Background:
- End-stage renal disease (ESRD) necessitates long-term hemodialysis.
- Vascular access is crucial for effective hemodialysis treatment.
- Comparing different vascular access modalities is essential for optimizing patient care.
Purpose of the Study:
- To evaluate the long-term efficacy and safety of primary arteriovenous fistula (AVF) compared to synthetic grafts for hemodialysis access.
- To determine the optimal vascular access procedure for patients with ESRD.
Main Methods:
- A retrospective study involving 533 vascular access sites.
- Data collected over 12,000 patient-months.
- Comparison of primary AVF, polytetrafluoroethylene (PTFE) grafts, and bovine carotid artery heterografts (BCAH).
Main Results:
- Primary AVF demonstrated the highest patency rates: 84% at three years versus 70% for PTFE and <50% for BCAH.
- Primary AVF group experienced significantly fewer complications (25/273) compared to BCAH (61/58) and PTFE (171/202).
- No deaths occurred due to access complications in the primary AVF group, unlike graft groups (7 deaths).
Conclusions:
- Primary AVF is the preferred procedure for chronic hemodialysis access due to superior patency and safety.
- AVF significantly reduces complications and mortality associated with vascular access in ESRD patients.
- The findings support the routine use of primary AVF for long-term hemodialysis access.
Abstract:
This study of 533 vascular access sites for long-term hemodialysis in patients with end-stage renal disease, accumulating more than 12,000 patient months, indicated that primary arteriovenous fistula (AVF) is the procedure of choice. The group receiving primary AVF had the greatest duration of patency: 84% at three years compared to 70% for the group receiving polytetrafluoroethylene (PTFE) grafts and less than 50% for those receiving bovine carotid artery heterografts (BCAH). Furthermore, the primary AVF group had fewer complications (25 complications in 273 fistulas) than either the BCAH group (61 in 58 grafts) or the PTFE group (171 in 202 grafts). No complication resulted in death in the primary AVF group, but seven deaths resulted from complications of the access in the graft groups, further solidifying the position of the primary AVF as the procedure of choice for chronic hemodialysis access.
