OBJECTIVES Recently, echo-tracking-derived measures of arterial stiffness have been introduced in clinical practice for the assessment of one-point pulse wave velocity. The purpose of this study was to find a relation between carotid-femoral pulse wave velocity and one-point carotid pulse wave velocity, and to find a value of one-point carotid pulse wave velocity that predicts carotid-femoral p...

BACKGROUND Epidemiologic studies of the association between alcohol consumption and carotid artery structure have reported conflicting results. We investigated the association between alcohol consumption and carotid atherosclerosis by evaluating the effects of alcohol intake on carotid artery enlargement. METHODS The study population consisted of 4302 community-dwelling Koreans (1577 men and ...

Electric carotid baroreflex activation has been used to treat patients with resistant hypertension. It is hypothesized that, in conscious rats, combined activation of carotid baro- and chemoreceptors afferences attenuates the reflex hypotension. Rats were divided into 4 groups: (1) control group, with unilateral denervation of the right carotid chemoreceptors; (2) chemoreceptor denervation grou...

BACKGROUND Directed ultrasonic screening for carotid stenosis is cost-effective in populations with > 5% prevalence of the diagnosis. Occasionally, calcifications in the area of the carotid arteries are incidentally detected on odontological panoramic radiographs. We aimed to determine if directed screening for carotid stenosis with ultrasound is indicated in individuals with such calcification...

background: carotid ultrasound appears to be useful in the assessment of cardiovascular risk. in this study, we have assessed the carotid intima-media thickness (cimt) in a group of individuals without a history of cardiovascular events. methods: a sample of 431subjects (189 [43.9%] males and 242 [56.1%] females) was obtained from an urban population using a stratifi ed-cluster method in mashha...

Background and Purpose—Change in cognition is being increasingly recognized as an important outcome measure; however, the role of carotid revascularization on this issue remains to be determined. It is still under debate whether carotid artery stenting and carotid endarterectomy have the same influence on neuropsychological functions. Summary of Review—This article systematically reviews recent...

HYPOTHESIS Extrathoracic cervical grafts are safe and provide long-lasting stroke prevention in patients with disease not amenable to standard carotid bifurcation endarterectomy. DESIGN Review of a prospectively maintained vascular surgical registry. SETTING Combined university and Department of Veterans Affairs vascular surgical service. PARTICIPANTS Patients requiring surgery for caroti...

Administration of nitric oxide (NO) or NO donors to isolated carotid sinus and carotid bodies inhibits the activity of baroreceptor and chemoreceptor afferent nerves. Furthermore, NO synthase (NOS) is present in endothelial cells and in sensory nerves innervating the carotid sinus region. The major goal of this study was to determine whether overexpression of NOS in carotid sinus modulates baro...

Carotid-cavernous fistulas may be classified into: (1) internal carotid, (2) external carotid, or (3) a combination of both. They may result from traumatic or spontaneous rupture of the carotid artery into the cavernous sinus. Intravascular embolization has become the treatment of choice for the management of carotid cavernous fistulas. The authors report the delayed effects after the treatment...

Carotid artery stenting (CAS) is one of the treatments for carotid stenosis; however, it associated with risk postoperative embolism due to in-stent plaque protrusion. CASPER Rx (Terumo, Co.) stent expected prevent protrusion because double-layered structure. Double-layer segment required be deployed over during placement; real-time understanding position difficult. Percutaneous ultrasound exam...
