Hemodialysis arteriovenous fistulas (AVFs) are suboptimally used primarily due to problems with maturation, early thrombosis, and patient nonacceptance. An endovascular approach fistula creation without open surgery offers another hemodialysis vascular access option.Prospective, single-arm, multicenter study (Novel Endovascular Access Trial [NEAT]).Consecutive adult non-dialysis-dependent dialysis-dependent patients referred for at 9 centers in Canada, Australia, New Zealand.Using...
