introduction: doppler ultrasonography (dus) is the most preferable method for screening of carotid artery disease in patients undergoing cabg. the purpose of this study was to investigate the frequency of carotid artery disease and determine the relation between known risk factors of atherosclerosis and rate of carotid artery narrowing in order to identify high-risk groups among patients schedu...

this is retrospective double-blind research, which was carried out in imam khomeini hospital in order to study the accuracy of color doppler ultrasonography for detecting the site and grade of stenosis in cervical carotid artery. 40 patients with mean age of 62 years studied with color doppler before dsa angiography. the most common sites of stenosis were left internal carotid (39.5%) and right...

Head and neck trauma in pediatric population differs from adult cases due to the immature cranio-cervical stability resulting from the weak neck musculature and large head to neck proportion. These cases also have drawn attention due to concomitant severe damage to the regional vascular structures such as carotid artery [1,2]. In some cases, especially with skull base fractures and cervical ver...

Background and Purpose A model for cerebral ischemia that requires injection of emboli into the internal carotid artery of the rabbit is commonly used. However, in our experience we have found the anatomy of the cervical carotid to be highly variable. If not appreciated, this may result in unexpectedly high variability in the severity of ischemic injury. We undertook this experimental protocol ...

A 40-year-old woman presented with symptoms compatible with Raeder syndrome. MR demonstrated narrowing of the left cavernous carotid artery. The high cervical portion of the left internal carotid artery was not identified. Angiography confirmed the narrowing of the cavernous carotid artery and showed marked and irregular stenosis of the distal cervical internal carotid artery. Involvement of th...

BACKGROUND AND PURPOSE Cervical internal carotid artery dissections are diagnosed with an increasing frequency, but reliable epidemiologic data are not available. The aim of this study was to determine the incidence rate of spontaneous cervical internal carotid artery dissection in a defined population. METHODS Using the medical record linkage system used for epidemiologic studies in Rocheste...

Aberrant right subclavian artery, the most common anatomic variant of aortic arch, occurs in 0.5% population. Symptoms generally result from compression esophagus and/or trachea as aberrant vessel passes posteriorly mediastinum. Treatment includes revascularizing artery carotid using a cervical approach combined with occluding origin thoracic aorta. We describe hybrid treatment for symptomatic ...
