BACKGROUND AND PURPOSE We propose to study possible differences in the associations between risk factors for cardiovascular disease (myocardial infarction and stroke) and carotid intima-media thickness (IMT) measurements made at 3 different levels of the carotid bifurcation. METHODS We conducted a cross-sectional study of a cohort of whites and blacks of both genders with a mean age of 45 yea...

the carotid sinus is a modification in the vascular wall near the bifurcation each common carotid artery and acts as baroreceptor. in this study 16 adult and apparently healthy buffaloes ie. 8 male and 8 female used for the as well as macroscopic orientation microscopic study of the carotid sinus. our study revealed that in the buffalo, carotid sinus is a dilatation in common carotid artery at ...

Severe thrombosis and its ischemic consequences such as myocardial infarction, pulmonary embolism and stroke are major worldwide health issues. The ferric chloride injury is now a well-established technique to rapidly and accurately induce the formation of thrombi in exposed veins or artery of small and large diameter. This model has played a key role in the study of the pathophysiology of thro...

Artery Arising from the Internal Carotid Artery I read with interest the article by Chan et al. They stated that there was a rare congenital anastomosis between the vertebral artery (VA) and internal carotid artery (ICA) with an absence of communication between the common carotid and cervical ICA. I, however, diagnose that there was an acquired occlusion of the ICA at its origin with a developm...

background: carotid artery stenting is now used as an alternative to surgical endarterectomy. this study was done to assess the feasibility, safety, and immediate and late clinical outcomes in patients undergoing carotid stenting . methods: between july 2008 and december 2009, a total of 40 patients (20 male, mean age: 65 ± 11 years, 19 symptomatic, and 90% high risk for endarterectomy) underwe...

Although carotid occlusive disease is not uncommon in adults (Fisher, 1954; Samuel, 1956), it is rare in children. Since atherosclerosis is accepted by most authors as the major aetiological agent, this is not surprising. A search of the literature reveals 16 cases of carotid occlusion in persons 10 years of age or less (Duffy, Portnoy, Mauro and Wehrle, 1957; Cabieses and Saldias, 1956; Behrma...

OBJECTIVE We tested the hypothesis that hyperhomocysteinemia and hypercholesterolemia promote arterial thrombosis in mice. METHODS AND RESULTS Male apolipoprotein E (Apoe)-deficient mice were fed one of four diets: control, hyperhomocysteinemic (HH), high fat (HF), or high fat/hyperhomocysteinemic (HF/HH). Total cholesterol was elevated 2-fold with the HF or HF/HH diets compared with the cont...

The carotid is a small mass of chemoreceptor's and sustentacular cells that detects changes in the composition of the arterial blood. The aim of the present study was to identify the size, color, location, blood and nerve supply of the carotid body in Makouei sheep. Fourteen heads of sheep from both sexes were collected from Urmia public slaughter-house. The exact situation and nerve supply of ...

OBJECTIVES Mild hyperhomocysteinaemia, fasting as well as after a methionine load, occurs in families and is associated with premature atherosclerosis. We hypothesised that endothelial dysfunction plays a role in the relation between hyperhomocysteinaemia and clinical vascular disease. METHODS In this study flow-mediated, endothelium-dependent vasodilatation of the brachial artery and, as a m...
