A 58 year old man was involved in a high impact road traffic incident and was admitted for observation. Asymptomatic for the first 24 hours, he collapsed with symptoms and signs consistent with a cerebrovascular accident. Computed tomography angiogram (CTA) and Magnetic resonance angiogram (MRA) demonstrated bilateral internal carotid artery dissections and a left middle cerebral artery infarct...

OBJECTIVE To determine the predictors of the extent of carotid atherosclerosis in patients treated with radiotherapy (RT) for nasopharyngeal carcinoma (NPC). METHODS The present study investigated 129 post-RT NPC patients. Carotid atherosclerotic parameters, such as carotid intima-media thickness, carotid arterial stiffness and carotid plaque burden (plaque score, the presence of plaque and ≥...

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 ...

To the Editor: Re: “Does detection of carotid plaque affect physician behavior or motivate patients?”, published online in the American Heart Journal in October 2007 and printed in December 2007 by Rachael A. Wyman, MD, Giorgio Gimelli, MD, FACC, Patrick E. McBride, MD, MPH, FACC, Claudia E. Korcarz, DVM, RDCS, and James H. Stein, MD, FACC In their observational study to evaluate the impact of ...

Atherosclerotic carotid stenosis (ACS) is a major cause of ischemic stroke. Screening for asymptomatic ACS is important to identify the patients who require longitudinal surveillance, medication, or endovascular surgery. The aim of this study was to assess the prevalence and risk factors for ACS and carotid plaque (CP) in Korea using a population-based screening study.We recruited participants ...

There are two points of view on the interplay between carotid artery disease and diabetes mellitus: Diabetes mellitus has been recognized as one of the main determinants for the presence and progression of asymptomatic and symptomatic carotid artery disease; and carotid intima-media thickness has been defined as a useful tool for risk stratification of this population. Hyperglycaemia, duration ...

the branches of external carotid artery were dissected and studied in six one humped camels.these specimens were preparated from slaughterhouse and fixed in10% formaline. the common carotid artery in one humped camel is divided into three branches , including , occipital artery , internal carotid artery and external carotid artery which in this respect it was similar to that of equine. external...

permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Previous studies have reported stroke magnetic resonance imaging (MRI) assessments that included a carotid magnetization-prepared rapid acquisition with gradient-echo (MPRAGE) sequence. The findings of these studies showed that a carotid MPRAGE-positive signal was...
