Effect of upper arm brachial basilic and prosthetic forearm arteriovenous fistula on left ventricular hypertrophy . BACKGROUND Creation of an arteriovenous fistula ( AVF ) may increase left ventricular hypertrophy in the hemodialysis population . Aim of this study was to compare the effects of a brachial-basilic ( BB ) AVF and the prosthetic brachial-antecubital forearm loop access ( PTFE ) on cardiac performance . METHODS Patients were randomized to receive BB-AVF or prosthetic brachial-antecubital forearm loop access . Before and three months after AVF creation patients underwent an echocardiographic examination . Mann-Whitney U-test was used to compare relative increase between the measured cardiac parameters for the two groups . RESULTS Twenty-seven patients participated in the study . The relative increase in left ventricular parameters was not significantly different between the two groups . Only left ventricular end-diastolic diameter tended to be of significance . Mean blood flow through the brachial artery was 1680+/-156 and 1450+/-221 mL/min three months after surgery for the PTFE and the BB-AVF group , respectively . CONCLUSION After three months of follow-up , changes in cardiac structure were comparable between patients with BB and PTFE AVFs . Also access flow was comparable at this time . In general , the effects of creation of a fistula on LV structure were limited . Longer follow up time may be needed to explore the long term effects of different vascular accesses on cardiac function .
