One-sheath inverse method in VAIVT for hemodialysis pts
Vascular access intervention therapy (VAIVT) is an essential interventional therapy in the field of hemodialysis therapy that allows for the long-term vascular access functionality to be maintained. The venous approach is often performed in VAIVT for arteriovenous fistula. When lesions are present on the upstream and downstream sides from the approach site, it is likely that two sheaths will be inserted from two facing punctures.

Published in the International Journal of Surgery Case Reports, the authors have used a one-sheath inverse method using a guidewire in such cases. The authors describe the steps of the technique and report the successful treatment of a 77-year-old woman who developed arteriovenous fistula failure.

The merit of the technique is that it allows VAIVT to be performed using one sheath with one approach site in cases in which lesions are present on the upstream and downstream sides from the approach site. The other benefits include pain reduction, a shortened operation time, and reduced costs. Because vascular access location is usually superficial, the technique can be utilized with relative ease.
