title: Management of the immature autogenous arteriovenous fistula.
abstract: A high-quality autogenous arteriovenous fistula provides the optimal access for hemodialysis. Following initial surgical construction of a fistula, the maturation process is driven by hemodynamic, cellular, and humoral factors that must result in increased blood flow, vessel dilation, and thickening of the vessel wall before the fistula can be successfully used for dialysis needle access. Different demands are placed on each fistula depending on the individual patient's hemodialysis requirements, which must be clearly understood to properly assess and treat the immature fistula. When spontaneous maturation fails to achieve a functional fistula, additional surgical or minimally invasive interventional procedures may be necessary to enhance the maturation process. Various techniques have been reported to achieve successful fistula maturation. The purpose of this article is to review the concepts of fistula maturation and the interventions that may be performed in cases where there is failure to mature spontaneously.
