case_images: The mapping indicated a radial artery of 2.7 mm, radial veins of 2.2 mm, an ulnar artery of 1.6 mm, and ulnar veins of 1 and 0.8 mm, along with a patent perforator vein of 2.9 mm (Figure 1), deeming the patient a good candidate for a right-sided percutaneous AVF.
case_images: Intraprocedural WavelinQ setup.. (A) Aligning the arterial and venous catheters and positioning the radiofrequency electrodes. (B) Pre-creation image of the native vessels with injections through the artery and vein. (C-F) Post-creation image of the EndoAVF.

case_images: AVF was created using the WavelinQ  4 F EndoAVF system (BD, Franklin Lakes, NJ, US) with a radio-radial approach (Figure 2). An immediate post-procedure measurement of the brachial artery flow indicated 460 mL/min.
case_images: Ultrasound study one month after the procedure. . (A) Basilic vein diameter. (B) Cephalic vein diameter. (C) Brachial artery flow.

case_images: FIG3
case_images: One month after the procedure, clinical and ultrasound follow-up confirmed proper development of the AVF, with a brachial artery flow of 1,212 mL/min, a cephalic vein diameter of 8.3 cm, and a basilic vein diameter of 6 mm, enabling the first AVF puncture two months later, which confirmed good AVF function with a Qa of 350 mL/min (Figures 3, 4).
case_images: First puncture of the EndoAVF in the cephalic vein pathway, both arterial and venous punctures.
