background: the incidence of stroke is 2.1-5.2% in bypass surgery patients with a mortality of 0-38%. this study was designed to evaluate the incidence of significant carotid artery stenosis and its related risk factors in candidates for coronary artery bypass graft (cabg) surgery. methods: 1045 consecutive candidates for cabg underwent carotid artery doppler examination in a prospective study....

the management of carotid artery stenosis reduces the risk of stroke and its related deaths.   management options include risk factor modification and medical therapy, carotid endarterectomy (cea), and carotid artery stenting (cas). although several randomized controlled trials (rcts), mostly conducted in late-1980s and mid-1990s, have proved cea to be effective in the prevention of ipsilateral...

Carotid artery is the most important artery that carries the major part of the blood supply to the head and neck. The branching of the common carotid artery usually occurs at the upper edge of the thyroid cartilage. The placement of carotid sinus has also increased its importance in this area. Considering the clinical importance of knowledge about carotid artery variations, this case is reporte...

background: the incidence of stroke after coronary artery bypass grafting (cabg) is between 0.9% and 6.7%, which significantly increases in-hospital and out-hospital costs. this study was designed to evaluate the prevalence of significant carotid stenosis and its risk factors in cabg. methods: in total, 2044 consecutive patients undergoing elective cabg were investigated through a pre-operative...

variation of the branches of the external carotid artery (eca) is well known, but it is extremely rare for the occipital artery (oa) to arise from the internal carotid artery (ica). a 87-year-old man was found to have this anatomical variation on the right side by threedimensional computed tomography angiography for vascular mapping of the carotid arteries before superselective intra-arterial c...

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 ...

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 ...
