The impact of pre-existing radial artery pathology by histological assessment on the maturation, function and patency of the radiocephalic fistula for hemodialysis.

Background: We prospectively analyzed the effect of preexisting structural changes of the radial artery (RA) wall by histological examination on the wrist radiocephalic fistula (RCF) outcomes.

Methods: During RCF creation, one segment of the RA wall was collected and its histomorphometric analysis was performed. The RCF function was evaluated by measuring blood flow rate.

Five years of vascular access stenosis surveillance by blood flow rate measurements during hemodialysis using the Delta-H method.

Purpose: To report experience over five years of vascular access (VA) stenosis surveillance.

Methods: We prospectively monitored the blood flow rate (QA) of 145 VA in 131 ESRD (age 62.6 ±13.
