External dilator-assisted banding for high-flow hemodialysis arteriovenous fistula

Figures & data

Figure 1. Radial artery before external dilator-assisted banding (EDAB) over 10-Fr dilator. Preoperative brachial artery flow and radial artery diameter was 3191 mL/min and 6.7 mm, respectively.

Figure 2. Suture tied over 10-Fr dilator.

Figure 3. Radial artery after banding. Postoperative flow was 1297 mL/min.
