Fistula Diameter Correlates with Echocardiographic Characteristics in Stable Hemodialysis Patients

Abstract

Aims and background Left ventricular hypertrophy (LVH) is a common finding in hemodialysis patients. The aim of the present study was to investigate if the diameter of the distal radiocephalic fistula could influence left ventricular variables in stable hemodialysis patients. Methods Nineteen patients were investigated. Measurements of the diameter of the arteriovenous (AV) fistula were performed in 4 different locations. The patients were investigated using M-mode recordings and measurements in the 2D image. Doppler ultrasound was also performed. Transonic measurements were performed after ultrasound investigation. Results Fistula mean and maximal diameter correlated with left ventricular characteristics. Fistula flow correlated neither with the left ventricular characteristics nor with fistula diameters. Conclusions The maximal diameter of the distal AV fistula seems to be a sensitive marker of LVH in stable hemodialysis patients.
