The cervical course of the internal carotid artery is almost straight in contrast to the intracranial portions which are highly tortuous. The incidence of variations in the cervical course of the internal carotid artery of the population is approximately 10-40 percent. In this case report, a 76-year-old female patient with a pulsatile mass at the posterior oropharyngeal wall and anterior neck w...

BACKGROUND AND PURPOSE Although it is known that smoking is associated with an increase in arterial wall thickness, most studies have been performed in heterogeneous groups of older age, already suffering from atherosclerotic diseases or having additional cardiovascular risk factors. The purpose of this study is to assess the effect on arterial wall thickness of the carotid and femoral artery i...

Transient three-dimensional laminar incompressible dilute suspension flow in rigid in-plane carotid artery bifurcations has been solved with a user-enhanced finite-volume program. Instantaneous velocity vector and wall shear stress vector fields illustrate strong "disturbed flow" patterns. Implications of elevated surface contours of hemodynamic wall parameters, indicating such disturbed flows,...

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...

objectives in this study, we aimed to investigate the changes in brain lipidomics following prolonged and intermittent ischemic preconditioning. materials and methods two groups underwent bilateral common carotid artery occlusion either intermittently (for 3 continuous periods within a timeframe of 20 minutes, releasing 3 consecutive times, yielding a total of 9 minutes (intermittent bilateral ...

Background: The carotid artery is an important blood vessel in the human body. Its ruptures caused by accidents can be lethal cases without timely treatment. Currently, successful rescue cases have rarely been reported, hence we present the following case. Case presentation: A patient who was a 46-year-old male admitted due to left neck trauma that lasted almost a day. The CT angiography (CTA) ...

background: common carotid arterial stiffness can be assessed during carotid arterial ultrasonography, but its association with brachial stiffness, a well-defined cardiovascular risk factor, has not been clarified. the aim of this study was to examine the relationship between common carotid artery and brachial artery stiffness. methods: the static pressure-strain elastic modulus of the common c...

vertebrobasilar insufficiency is the cause of cerebrovascular accidents in 20% of cases. there are few reports regarding spectral doppler indices (sdis) of vertebral arteries (vas) normal blood flow. the objective of this study was to provide basic reference data about sdis of vas normal blood flow separately and in comparison with internal carotid arteries (icas) and common carotid arteries (c...

Diabetes is associated with a reduction of arterial distensibility. Limited information exists regarding whether or how early this appears in the course of the disease. We studied 54 normoglycemic, normotensive, healthy offspring of 2 parents with type 2 diabetes mellitus and 55 age- and sex-matched healthy control subjects. Carotid diastolic diameter and systodiastolic change were measured by ...

OBJECTIVES The present study was designed to assess whether a diuretic- or an angiotensin-converting enzyme inhibitor-based treatment can reduce arterial wall hypertrophy of a distal muscular medium-sized artery--the radial artery--and the stiffness of a proximal large elastic artery--the common carotid artery. BACKGROUND Large-artery wall thickness and stiffness are increased during sustaine...
