Abstract

Introduction: Various methods for vascular access (VA) management have been studied. We investigated the usefulness a new, simple, and quantitative VA management method using the Pocket LDF® laser blood flowmeter (hereinafter “LDF”) that non-invasively measures peripheral circulation flow. Methods: Peripheral circulation flow was measured in 82 patients (43 men) on maintenance hemodialysis with an arteriovenous fistula (AVF). The shunt symmetry index (SSI) was calculated as peripheral circulation flow in the AVF limb divided by that in the non-AVF limb. SSI was used for microcirculation evaluation and also compared by AVF site. Patients undergoing vascular access interventional therapy (VAIVT) underwent ultrasound evaluation (Doppler ultrasonography) of the AVF and SSI measurement before and after VAIVT. SSI was compared between those who did and did not require VAIVT, and the cutoff value for SSI was determined by receiver operating characteristic curve (ROC) analysis. Results: As many as 86% of the patients who were measured peripheral circulation flow had SSI 1.06. Our results suggest the usefulness of the described VA management method using the LDF.
