INTRODUCTION: Currently, there is no reliable method to differentiate acute from chronic carotid occlusion. We propose a novel CTA-based method to differentiate acute from chronic carotid occlusions that could potentially aid clinical management of patients. METHODS: We examined 72 patients with 89 spontaneously occluded extracranial internal carotids with CT angiography ...

Carotid artery stenosis is a major risk factor leading to cerebral infarct, transient ischemic attack (TIA), and ischemic stroke in the United States. While carotid endarterectomy (CEA) surgery has been established as an effective treatment option for severe carotid artery stenosis, many risks remain inherent in performing this procedure. Surgeons ...

The presence of aortic valve sclerosis has been suggested as a marker of increased cardiovascular risk, including increased mortality. However, it remains unclear whether aortic valve sclerosis is independently associated with risk or merely a marker of coexistent cardiovascular risk factors. Aortic valve sclerosis is usually diagnosed on transthoracic echocardiography, ...

Interferon (INF)-associated retinopathy occurs in 15-64% of INF-treated patients, transforming this complication into a significant risk for visual impairment. This retinopathy has been described as an ocular complication with a variable clinical course, usually benign and asymptomatic. The most common findings are hemorrhages and cotton wool spots. Atypical ocular side ...
