Abstract

Background: The most common form of vascular access for hemodialysis is a native arteriovenous fistula, which connects site of the artery to the end of the vein. The maturation process of the fistula plays a crucial role in the establishment of a functional vascular access. Radial artery stenosis is among others a potential cause of maturation failure. In these cases, improving the fistula's blood flow may be difficult, as traditional surgical reanastomosis and endovascular intervention frequently fail. Radial artery deviation and reimplantation (RADAR) is a novel, effective technique for creating primary fistulas with a high patency rate. The main disadvantage of this procedure is the ligation of the radial artery and the subsequent known consequences. Methods: In order to accelerate maturation, we used RADAR as a secondary fistula in three patients with radial artery stenosis and maturation failure. In all patients after surgery we observed significant increase in fistula blood flow. Two patients used fistula for hemodialysis after surgery. We describe the image diagnosis, procedure, and benefits of this method based on a single case. Conclusion: The RADAR technique may be successfully used as a secondary access in patients with maturation failure, due to RA stenosis to accelerate fistula maturation.
