Summary

Arteriovenous fistulas (AVFs) are the preferred type of vascular access for dialysis, but many of them fail to mature. The optimal timing of intervention to salvage immature AVFs is unknown.The study proposes a randomized clinical trial comparing the clinical and economic impact of early vs late angioplasty in non-maturing AVFs.

The study proposes a RCT to test the hypothesis that, as compared to early angioplasty of non-maturing AVFs, late angioplasty results in a lower proportion of AVFs being used at 6 months, but a greater long-term AVF patency , lower requirement of subsequent interventions to maintain AVF patency for dialysis, and lower overall cost of access maintenance.

Conditions

  • Immature Arteriovenous Fistula

Interventions

PROCEDURE

early Angioplasty

Angioplasty is a minimally invasive, endovascular procedure to widen narrowed or obstructed arteries or veins. A deflated balloon attached to a catheter (a balloon catheter) is passed over a guide-wire into the narrowed vessel and then inflated to a fixed size. The balloon forces expansion of the blood vessel and the surrounding muscular wall, allowing an improved blood flow. This is part of standard of care for immature arteriovenous fistulas. Early means pt will get the procedure at 6 weeks from time of initiation of AVFs

PROCEDURE

late Angioplasty

Angioplasty is a minimally invasive, endovascular procedure to widen narrowed or obstructed arteries or veins. A deflated balloon attached to a catheter (a balloon catheter) is passed over a guide-wire into the narrowed vessel and then inflated to a fixed size. The balloon forces expansion of the blood vessel and the surrounding muscular wall, allowing an improved blood flow. This is part of standard of care for immature arteriovenous fistulas. Late means the angioplasty is done at 3 months from time of AVF creation if still immature at that time.
