Scribner shunt conversion to arteriovenous fistula.

Area of Science:

• Nephrology
• Vascular Surgery

Background:

• Scribner shunts are a temporary vascular access for hemodialysis.
• Arteriovenous fistulas offer a more durable long-term vascular access option.

Purpose of the Study:

• To evaluate the conversion of Scribner shunts to arteriovenous fistulas.
• To assess the long-term success and complications of this conversion.

Main Methods:

• Retrospective analysis of 26 patients undergoing shunt to fistula conversion.
• Evaluation of fistula patency, infection rates, and usability for dialysis.

Main Results:

• Successful long-term function was achieved in 20 out of 26 patients.
• Two patients experienced infection, leading to fistula loss.
• Fistulas were utilized for both home and center-based hemodialysis.
• The converted fistulas served as both primary and backup access sites.

Conclusions:

• Conversion of Scribner shunts to arteriovenous fistulas is a viable option for long-term hemodialysis access.
• While generally successful, infection remains a potential complication.
• The resulting arteriovenous fistulas provide versatile access for various dialysis modalities and roles.
