ABSTRACT

Endothelial disfunction, its a condition that starts before seeing atheroma plaques in the coronary arteries. The need to obtain a non-invasive evaluation of the endothelial function measuring the flow mediated dilation (DMF) of the brachial artery, requires of a support for the forearm and fixating over the artery in the same axis than the brachial artery an ultrasound transducer. To realize DMF studies with reduced artifacts we developed and implemented support tables for the forearm and a fixation device for the ultrasound transducer, to obtain adequate measuring precision of DMF. 99 studies were done and analysed from May 2008 to July 2010. With the development of the third table we observe that the artifacts were eliminated almost completely with less than 5% in the variability. The development of ostensive improvements on the support tables and fixation of the transducer that ensures adequate relation between the axis of the transducer with the longitudinal axis of the brachial artery were necessary to obtain adequate DMF studies.
