Venous stenosis and thrombosis as a result of venous neointimal hyperplasia are the major causes of hemodialysis vascular access dysfunction. This review describes the lesion of venous neointimal hyperplasia in human samples and in a pig model and suggests possible future directions for the development of effective local therapies for this condition.

Potential fistula-related problems which may impact on patient survival include high fistula flow with hyperkinetic circulation and cardiac failure, low fistula flow with the risks of underdialysis and fistula thrombosis, vascular access infection with local or systemic manifestations, and possibly induction and maintenance of a microinflammatory state. All of these problems are briefly reviewed in this article.

The effects of diameters of canine femoral arteriovenous fistulas upon regional and central hemodynamics were determined to correlate fistula size with fistula flow, as well as changes in cardiac output, reversal of distal arterial flow, and distal venous hypertension. The study shows that there is a direct correlation between fistula size and cardiac output, a direct correlation between fistula size and venous hypertension and an inverse relation between fistula size and distal femoral artery flow and pressure.
Joseph S, Adler S. Vascular access problems in dialysis patients: pathogenesis and strategies for management. Heart Dis 2001;3:242-247.
This article describes the means of accessing the circulation for hemodialysis, the pathogenesis of access failure through progressive stenosis followed by thrombosis, methods of detecting access dysfunction before thrombosis, and therapeutic options. Although angiographic or surgical intervention remain the mainstays of management, medical treatments to decrease stenosis and delay thrombosis are currently under investigation.

Physiologic and hemodynamic issues related to the construction of a vascular access for hemodialysis are reviewed in this section. These issues provide the basis for the understanding, prevention and treatment of vascular access complications.
