The purpose of this study was to establish valid indexes of conduit and resistance vessel structure in humans by using edge detection and wall tracking of high-resolution B-mode arterial ultrasound images, combined with synchronized Doppler waveform envelope analysis, to calculate conduit artery blood flow and diameter continuously across the cardiac cycle. Nine subjects aged 36.7 (9.2) yr unde...

OBJECTIVES The goal of this study was to prospectively examine the long-term predictive value of brachial-artery endothelial dysfunction for future cardiovascular events. BACKGROUND Brachial-artery endothelial function is impaired in individuals with atherosclerosis and coronary risk factors. The prospective relation between endothelial function determined by brachial-artery ultrasound and lo...

The measurement of brachial artery vasodilation in response to a hyperaemic stimulus has been used extensively to assess changes in endothelial function. However, whether or not similar changes occur in response to an active hyperaemic stimulus is unknown. The purpose of the present study was to compare brachial artery vasodilation in response to an active compared with a reactive hyperaemic st...

AIMS To examine the acute effect of red wine and de-alcoholized red wine on endothelial function. METHODS AND RESULTS High frequency ultrasound was used to measure blood flow and percentage brachial artery dilatation after reactive hyperaemia induced by forearm cuff occlusion in 12 healthy subjects, less than 40 years of age, without known cardiovascular risk factors. The subjects drank 250 m...

The brachial artery is the commonest artery injured in the extremities. Although the patients present late, nevertheless reconstructions is advocated in other to salvage the limb and maintain function of the hand. We retrospectively examined 25 consecutive patients with vascular injuries treated at The Cardiovascular and Thoracic Surgery Unit of a tertiary health centre over a period of 4 years...

OBJECTIVE Our aim was to study the significance of persistently absent radial pulse, with monophasic doppler flow after close reduction percutaneous pinning of displaced supracondylar fracture of humerus, and the need of early exploration of brachial artery in such cases. METHODS Between July 1992 and 1999, 86 children with Grade III supracondylar fracture of humerus were treated at King Khal...

BACKGROUND The relation between dietary fish intake and brachial artery measures, including brachial artery flow-mediated dilation (FMD), has not been well established across sex and racial-ethnic groups. OBJECTIVE We hypothesized that consumption of nonfried fish and plasma phospholipid measures of long-chain omega-3 (n-3) fatty acids would be positively associated with larger FMD in men and...

The brachial artery is rarely injured in closed posterior dislocation of the elbow, unlike the high rate of vascular injury seen after dislocation of the knee. Despite the anatomical proximity of the brachial artery to the elbow joint, most cases of brachial artery injury after dislocation of the elbow are related to an associated fracture, an open injury or high-energy trauma. A high index of ...
