BACKGROUND The purpose was to examine the temporal response of the brachial artery diameter following 5 minutes of forearm occlusion in young men. A secondary objective was to compare the main features of the temporal pattern between young and old. METHODS Sixteen young (28 +/- 8 yrs) and fifteen older (85 +/- 8 yrs) men underwent high-resolution ultrasonography of the brachial artery before ...

INTRODUCTION Brachial artery occlusion is a documented complication after catheterization procedures performed via the brachial artery. These are mainly managed conservatively or with surgical thrombo-embolectomy. We present a case with acute brachial artery occlusion successfully managed with balloon angioplasty and thrombolytic therapy. CASE PRESENTATION A 68-year-old African-American femal...

OBJECTIVE Vascular impairment, a main feature of the pathogenesis of systemic sclerosis (SSc), involves both the macro- and the microvasculature. We compared and correlated simultaneously measured skin microvascular and brachial artery macrovascular post-occlusive hyperemia in 3 groups: patients with SSc, patients with primary Raynaud's phenomenon (RP), and healthy volunteers. METHODS Thirty-...

Variations in course of the arteries are well documented. Knowledge of the variation of the arterial system is important during vascular and reconstructive surgeries, in the evaluation of angiographic images. During routine anatomical dissection of upper limb ,of adult male cadaver of 55 years in Department of anatomy, SNMC, Agra, we came across a variant origin of the ulnar artery, instead of ...

BACKGROUND Decreased large artery function, as reflected by increased brachial artery pulse pressure and increased carotid artery diameter and stiffness, may contribute to the increased mortality risk that is observed in subjects with impaired glucose tolerance. We therefore investigated the association between brachial artery pulse pressure and carotid artery diameter and stiffness, which are ...

OBJECTIVE The aim of this study is to introduce a microvascular training model based on use of materials that can be easily obtained from the daily surroundings. METHODS Simple microinstruments and a medical school laboratory microscope were used for anastomosis training. Chicken blood vessels were used as a material for this study. A long segment of blood vessel from the proximal brachial ar...

INTRODUCTION Ultrasound measurements of brachial artery reactivity in response to stagnant ischemia provide estimates of microvascular function and conduit artery endothelial function. We hypothesized that brachial artery reactivity would independently predict severe sepsis and severe sepsis mortality. METHODS This was a combined case-control and prospective cohort study. We measured brachial...

BACKGROUND Impaired arterial dilatation response to nitroglycerin has been observed in adults with risk factors for atherosclerosis and in patients with established atherosclerotic disease. This defect parallels changes in vascular endothelial function and may be attributed to increased oxidative stress. Because atherosclerosis begins in childhood, we examined the correlates of nitrate-mediated...
