Non-invasive ultrasound techniques to assess flow-mediated vasodilation (FMD) are frequently used to assess arterial endothelial vasodilator function. However, the range of normal values varies considerably, possibly due to differences in methodological factors. We sought to determine the effect of occlusion cuff position on the time course and magnitude of brachial artery blood flow and flow-m...

During a routine dissection a superficial artery was observed coursing subcutaneously at the anterior border of the axillary base towards the thoracic wall and bilaterally at the lower border of the pectoralis major muscle. On the right side it originated from the 3rd part of the axillary artery but on the opposite side the origin was from the first centimetre of a left radial artery originatin...

Previous work from our laboratory demonstrated that isometric handgrip (IHG) training improved local, endothelium-dependent vasodilation in medicated hypertensives [McGowan CL (PhD Thesis), 2006; McGowan et al. Physiologist 47: 285, 2004]. We investigated whether changes in the capacity of smooth muscle to dilate (regardless of endothelial factors) influenced this training-induced change, and w...

Background The median artery (transitory artery) represents the forearm’s embryonic arterial axis. At 8th week of gestation retreats into a little canal that supplies nerve. Later, ulnar and radial arteries take its place. Adults may still have it in either palmar or an antebrachial pattern. persistent are long, angular extends to hand’s surface. only partially recedes type.
 Objective To ...

OBJECTIVE: The purpose of this study was to evaluate the association between the presence of clinical symptoms of peripheral artery disease and severe renal artery stenosis in patients referred for renal angiography. METHOD: We included 82 patients with clinical suspicion of renovascular hypertension and performed an imaging investigation (renal Doppler ultrasound and/or renal scintigraphy) f...

Axillary artery pulsations serve as a landmark for clinical procedures like brachial plexus block and subclavian vein puncture. Axillary artery is also increasingly being utilized as a graft for coronary artery bypass. The present article reports a rare case of axillary artery variation. In this case, gross deviation from the normal anatomy was observed in an adult embalmed cadaver. Axillary ve...

The axillary neurovascular structures are one of the potential anatomical fields to show variations in many ways. The axillary artery gets divided in three parts by the fore lying pectoralis minor and provides the superior thoracic artery from first part, thoraco-acromial artery, lateral thoracic artery from second part and the third part gives anterior circumflex humeral, posterior circumflex ...

AIM Nitroglycerin-mediated vasodilatation (NMD) provides insight into the NTG-induced bioactivity of smooth muscle. It is plausible that in dysfunctional smooth muscle cells, the response to nitroglycerin may become blunted. The relationship between impaired brachial artery NMD and subsequent cardiovascular events is not well established. METHODS We examined brachial artery flow-mediated dila...
