Background: Lichen planus is a chronic inflammatory disease associated with an increased risk of subclinical atherosclerosis and cardiovascular diseases. This study aimed to evaluate patients with lichen planus using carotid Doppler ultrasound parameters.Methods: Forty patients with lichen planus and 40 controls were included in this study. Common carotid...

introduction: arterial stiffness is an important predictor of cardiovascular risk. several indices have been  introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. since the  substitution  of  the  blood  pressure  changes  in  the  central  arteries  such  as  carotid  with  the  blood  pressure  changes in the brachial results in error in the blood...

Doppler sonography of 29 extracranial carotid arteries was performed twice within three days or less. Angiography revealed stenoses with from 10 to 95% diameter reduction in 25 internal carotid arteries whereas four vessels were found to be normal. The systolic peak frequency of the internal carotid artery read from the Doppler spectrum (n = 29) could be reproduced very well. This was shown by ...

BACKGROUND AND PURPOSE The degree of internal carotid stenosis has emerged as the most important predictor of ischemic stroke in extracranial carotid artery disease. The purpose of this study was to assess the validity of the noninvasive techniques for quantifying internal carotid stenosis with respect to the accepted standard of intra-arterial angiography. METHODS We measured the maximum per...

The reliability of quantitative evaluation by doppler ultrasound with regard to the ophthalmic collateral blood flow in patients with carotid artery occlusion was estimated. The ultrasonic doppler flow signals of the ophthalmic collateral flow of 54 carotid occlusions were classified into four types and three degrees--high, moderate, and low reversed flow patterns--and were compared with the an...

introduction: prevalence of stroke following coronary artery bypass graft surgery (cabg) is % 2.1-5.2 and associated with high mortality. the purpose of this study was to investigate the prevalence of carotid artery disease in patients undergoing cabg surgery.  methods: this cross-sectional study was performed in the years 2010-2011 on 192 patients who underwent open heart surgery (cabg) in ima...

The carotid color Doppler ultrasound is usually the first imaging modality employed for the assessment of patients with cerebrovascular symptoms. The recognition of the distal stenoocclusive flow pattern is key for the detection of spontaneous dissection of the internal carotid and vertebral arteries in young patients who present cerebral ischaemic signs. We present six cases of patients whose ...

BACKGROUND AND PURPOSE Distal to a hemodynamically significant stenosis, the Doppler effect becomes dampened. Thus, measuring the flow profile in the ophthalmic artery and the central retinal artery with color Doppler imaging may provide hemodynamic information about the carotid circulation. METHODS To validate the flow profile measurement with color Doppler imaging in the ophthalmic and cent...

The Detection of Carotid Artery Obstruction: A Correlation With A rteriography • Intravenous radioisotope arteriography, carotid compression ocular plethysmography, and supraorbital Doppler studies were more accurate than ophthalmodynamometry in the detection of the presence or absence of carotid artery obstruction in 35 patients. Abnormal results were present in patients with carotid obstructi...
