Popis: Purpose To evaluate the effectiveness of local delivery of heparin via hydrogel-coated balloons in the treatment of vascular stenoses associated with hemodialysis access. Materials and Methods This was a randomized, prospective trial comparing treatment with hydrogel-coated balloon catheters delivered with heparin coating ( n = 33) and without ( n = 26). All patients were undergoing hemodialysis, and all stenoses involved the venous anastomosis of a dialysis graft or a native vein. The heparin-treated balloons were soaked in concentrated heparin and delivered in a protected manner to help prevent washout of heparin. Results The mean primary patencies were 143 days with heparin treatment and 214 days without heparin ( P = .174). The mean assisted primary patencies were 165 days with heparin and 194 days without ( P = .315). The mean secondary patencies were 351 days with heparin and 384 without ( P = .81). Conclusion In this population with this technique, the treatment outcome of venous outflow stenosis in patients with dialysis grafts is not improved with local delivery of heparin.
