  3. Vascular abnormalities in patients receiving a dialysis access.
    Michael Allon; Fiscal Year: 2010
    ..Unfortunately, about 50% of fistulas don't mature, and therefore cannot be used for dialysis. The goal of this study is to identify abnormalities of the arteries and veins that predict whether a fistula will mature. ..
