“…Because dialysis is necessary to sustain life, temporary dialysis access has to be created in cases in which the fistula cannot be saved. Thus, monitoring the health of the fistula is vitally important, and varied methods for surveillance of fistula function have been developed (7–10). While arteriography can provide detailed data of blood flow and the presence of stenosis and thrombosis, the technique is invasive and costly.…”

Ultrasonographic Assessment of Polytetrafluoroethylene Upper Extremity Arteriovenous Hemodialysis Access: A Retrospective Analysis of 31 Cases

Polytetrafluoroethylene (PTFE) vascular grafts are used for hemodialysis vascular access. Because their longevity is less than that of autologous fistulae, close surveillance is necessary to reduce the incidence of complications. The purpose of this study was to evaluate the usefulness of Doppler sonography for the surveillance of PTFE graft hemodialysis access. Thirty-one patients with renal failure who had dialysis access created with a PTFE graft were included in this study. The patient records along with ultrasonography were retrospectively reviewed. Two-dimensional ultrasonography clearly revealed the U-shape of the subcutaneous PTFE graft, and autologous artery and superficial vein connecting with the graft. There was no ultrasound echo inside the graft, but the wall was a continuous line-like hyperechoic structure. Blood flow in the graft and hemodynamic parameters could be determined with color Doppler ultrasonography. Ultrasound examination diagnosed graft thromboses in six patients, pseudoaneurysm in two, seroma in one, and subcutaneous edema in three patients. Ultrasonography is useful for the monitoring and diagnosis of complications of PTFE dialysis access grafts.

Dialysis Access: An Increasingly Important Clinical Issue

2009

View full text Add to dashboard Cite

Dialysis access, including vascular access for hemodialysis and peritoneal access for peritoneal dialysis, is critical in the clinical care of patients with end-stage renal disease. It is associated with increases in morbidity, mortality, and health care costs. A number of problematic issues are involved, some of which are addressed in this paper with reference to the most recent publications, including: the inappropriately low prevalence of peritoneal dialysis in Western countries, which is relevant to access placement in the pre-dialysis stage; the excessively high use of central venous catheters in incident and prevalent dialysis patients; the diagnosis and treatment of steal syndrome; the advantages and limitations of antiplatelet therapy; and finally, the correct pre-operative evaluation and subsequent surveillance of the vascular access.
