WebBefore HD treatments, patients will need an internal or external dialysis access placed by a vascular surgeon or a trained healthcare provider. This access allows blood to flow between the body and the dialyzer, pulling unfiltered blood from the body using negative pressure and returning the filtered blood back to the body using positive pressure. WebMay 31, 2024 · Hemodialysis access stenosis is a pervasive problem that occurs due to the physiology of the high-flow circuit. Stenosis occurs due to endothelial and smooth muscle injuries that result in neointimal hyperplasia. Percutaneous transluminal angioplasty is the standard treatment for dialysis access-induced stenosis.
