WCN24-1464 MEASUREMENT OF CEREBRAL BLOOD FLOW USING TRANSCRANIAL DOPPLER ULTRASOUND: COMPARISON OF TWO POPULATIONS OF PATIENTS IN CHRONIC HEMODIALYSIS

Patients on hemodialysis (HD) experience systemic and cerebral hemodynamic changes that are associated with cognitive impairment. It has not been studied whether having an arteriovenous fistula (AVF) may be a factor associated with the decrease in cerebral blood flow during HD. The objective of this study was to quantify and compare hemodynamic changes at the cerebral level during an HD session in patients with AVF vs. those with a high-flow catheter (HFC).
