Abstract

Purpose: The aim of this study was to evaluate flow volume and anastomosis diameter of native arteriovenous fistulas(AVF). Materials and Methods: 16 patients with native AVF were evaluated using Doppler Ultrasound. Eleven of 16 patients had upper arm AVF (bachiocephalic or brachiobasillic) and 5 of 16 patinets had forearm AVF (radiocephalic). Twelve of 16 patients had not symptoms. There was edema of upper extremity in 4 patients.Brachial artery flow volume and AVF anastomosis diameter were calculated using Doppler ultrasound. Fistulography was performed on 3 of the 4 patients who had upper extremity edema. Results: The brachial artery flow volume was calculated to be less than 2000ml/min in 14 of the 16 patients. The mean AVF anastomosis diameter was 3.6 mm in these patients. Whose flow volume of brachial artery were 4400ml/min and 6000ml/min. The diameters of AVF anastomosis were 6.9 mm and 10 mm in the 2 patients. Whose fistulography showed subclavian veinthrombosis in 2 patients and subclavian vein stenosis in 1 patient. Conclusion: Inthis study, diameter ofAVF anastomosis withhighflow volume was greater than diameter ofAVF anastomosis with normal flow volume. Increased diameter of AVF anastomosis may be responsible for an increased flow volume of AVF.
