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...

OBJECTIVES This study investigated (a) the hypothesis that stroke patients with aortic atheroma would show comparable atherosclerotic changes in the carotid arteries, which are easily accessible for ultrasound evaluation and (b) the possibility of carotid duplex sonography as a replacement for transoesophageal echocardiography (TEE) for the exclusion or prediction of relevant aortic plaques. ...

Introduction. Currently, despite the introduction of modern diagnostic algorithms in 20-40 % patients with ischemic stroke, it is not possible to establish its cause. Potential causes acute cerebral ischemia cryptogenic stroke include paroxysmal atrial fibrillation, patent foramen ovale, cardiomyopathy, carotid network, aortic arch atheroma, and cancer-associated thrombophilia. Target : systema...

Background & Aims: Diabetes is a very important factor for stroke due to blocked blood vessels. It can involve systemic and cerebrovascular arteries at the same time via microangiopathy and macroangiopathy. This project aimed to compare the intima-media thickness of carotid artery in children with diabetes type and the control group. Methods: In this case-control study, 50 children with the age...

The article by Zhao et al 1 is the first definitive study to describe the use of high-resolution MRI to monitor the effects of intensive drug treatment on the dimensions and composition of atherosclerotic plaques in human carotid arteries. (An earlier brief rapid communication by Corti and coworkers2 described the effect of lipid-lowering therapy on carotid and aortic vessel dimensions but not ...

PURPOSE To determine whether spiral CT angiography allows accurate, quantitative evaluation of anatomic abnormalities, including detection of additional lesions, delineation of plaque morphology, and estimation of degree of internal carotid artery stenosis. METHODS Spiral CT angiography with a maximum intensity projection technique was compared with selective digital subtraction angiography (...

Objective: Six cases in which carotid artery stenting (CAS) was performed using a distal embolic protection device (EPD) for distal internal carotid artery (ICA) stenosis near the carotid canal are reported. Case Presentations: Of the 504 consecutive cases of ICA stenosis endovascularly treated at our hospital between April 1, 2008 and December 31, 2016, six cases with lesions in the distal pot...

BACKGROUND Chronic Chlamydia pneumoniae infection has been implicated in the pathogenesis of atherosclerosis but whether it plays a role at an early stage in the disease is uncertain. An early estimate of atherosclerosis can be obtained by ultrasonic imaging of the carotid artery to determine intima-media thickness (IMT) and the thickness of any atheroma plaques. METHODS AND RESULTS In 983 no...
