BACKGROUND AND PURPOSE The purpose of this study was to determine whether significant atherosclerotic disease in the carotid arteries predicts significant atherosclerotic disease in the coronary arteries, vertebral arteries, or aorta in patients with symptoms of acute ischemic stroke. METHODS Atherosclerotic disease was imaged using CT angiography in a prospective study of 120 consecutive pat...

BACKGROUND Little information exists regarding development of vasomotor control mechanisms during coronary collateral artery maturation. Therefore, we studied endothelium-dependent relaxation of canine collateral arteries isolated 2, 4, and 9 months after placement of an ameroid occluder around the proximal left circumflex coronary artery. RESULTS Collateral arteries isolated after 2 months e...

The diagnostic modalities for giant cell arteritis (GCA) have evolved significantly in recent years. Among the different tools developed, Doppler ultrasound of temporal arteries, with a sensitivity and specificity reaching 69% 82%, respectively, is now recognized as superior and, therefore, first-line tool GCA. Moreover, increasing development new technologies, accuracy GCA seems to be constant...

Polyarteritis nodosa (PAN) is a necrotizing vasculitis that targets medium-sized muscular arteries and can involve small-sized arteries. The pathogenesis of classic PAN remains unclear, except for secondary or indistinguishable from due to genetic abnormalities such as deficiency adenosine deaminase 2. histopathological characters change over time the onset. type remission induction therapy be ...

In helically cut stripes of monkey coronary arteries of different sizes, contracted with prostaglandin F2 alpha or K+, responses to norepinephrine, epinephrine, isoproterenol, and transmural electrical stimulation were compared. In response to norepinephrine, only contractions were induced in large arteries, contractions at low concentrations and relaxations at high concentrations in medium-siz...

PURPOSE Both aging and the consumption of a high salt diet are associated with clear changes in the vascular system that can lead to the development of cardiovascular disease; however the mechanisms are not clearly understood. Therefore, we examined whether aging and the consumption of excess salt alters the function of potassium ATP-dependent channel signaling in mesenteric arteries. METHODS...

A clinical case of successful treatment a patient with atherosclerotic peripheral artery disease and clinically significant lesion the coronary carotid arteries. Patients underwent multi-stage surgical treatment. The first stage performed endovascular left internal artery, second — myocardial revascularization, third iliac arteries, fourth rotational atherectomy stenting right superficial femor...

Objective: Laminitis is one of the main causes of lameness in dairy cattle. In this situation the corium blood circulation is disrupted and the production of healthy horny hoof wall is reduced. The purpose of this study was to evaluate the arteriographic pattern of the digital arterial branches in the laminitic digits and to compare them with the normal digits. Design: Original study. Animals...
