In the developed world, atherosclerosis is by far the most common cause of renovascular disease. This normally develops at the renal artery ostium on the luminal surface of the aorta/proximal renal artery. The atheroma obstructs renal blood flow and leads to chronic renal ischaemia. Atheroma may account for >90% of cases in white vascular high-risk populations. Renal artery atheroma is commonly...

BACKGROUND AND PURPOSE Calcified arterial plaque has been proposed as a subclinical marker of atherosclerosis. We compared it to a well-validated surrogate--carotid intimal medial thickness (IMT). METHODS Calcified arterial plaque was measured in 2 vascular beds (coronary and carotid) by computed tomography, and common carotid artery IMT was measured by B-mode ultrasonography, in 438 particip...

BACKGROUND AND PURPOSE Previous articles have demonstrated that carotid artery plaques may have enhancement after administration of contrast material. The purpose of this study was to evaluate the effect of enhancement in carotid artery classification. MATERIALS AND METHODS Three hundred eighty consecutive patients (235 men, 145 women; median age 64, age range 32-87 years) were analyzed using...

The morphology of atherosclerosis between the carotid and coronary artery systems was studied in 63 patients with ischemic heart disease to determine if there was a correlation with coronary heart disease. The sclerotic lesions of the carotid and coronary artery systems were imaged with ultrasonography and coronary arteriography, respectively, and divided into 4 types. Hemodynamic variables, se...

BACKGROUND Treatment of instent restenosis after carotid artery stenting because of circumferential or calcified lesions can be difficult and refractory to conventional balloon angioplasty. We describe the off-label use of a cardiac scoring balloon that was used for lesions refractory to angioplasty with other balloons. CASE DESCRIPTIONS Two patients with a history of carotid artery stenting ...

OBJECTIVES To assess the prevalence of images suggestive of calcified carotid artery atheromas (ISCCAA) in panoramic radiographs of patients under dental treatment. MATERIALS AND METHODS The sample consisted of 8.338 panoramic radiographs from female (n=5.049) and male (n=3.289) patients under dental treatment between 4 and 94 years of age. The panoramic radiographs were evaluated searching f...

BACKGROUND AND AIMS This study was designed to evaluate the prevalence of calcified carotid artery in 50 year-old and older postmenopausal dental outpatients for early diagnosis of individuals at risk of stroke. MATERIALS AND METHODS This is a descriptive study of 200 panoramic radiographs. These radiographs included post-menopausal women referring to the Department of Oral Medicine at Shahid...

Cervical internal carotid dissection is not rare. Doppler ultrasound screening of young patients presenting with stroke, identified 10 patients with reduced common and internal carotid blood flow without any evidence of atheroma. Eight, on angiography proved to have a dissection of the cervical internal carotid artery. All were managed conservatively. Seven received anticoagulant therapy, stopp...

Albuminuria and reduced estimated glomerular filtration rate (eGFR) associate with two apolipoprotein L1 gene (APOL1) variants in nondiabetic African Americans (AAs). Whether APOL1 associates with subclinical atherosclerosis and survival remains unclear. To determine this, 717 African American-Diabetes Heart Study participants underwent computed tomography to determine coronary artery-, carotid...
