Carotid arteriosclerosis is the main cause of stroke but it can also lead to ophthalmic symptoms. In this article, we aim present four patients. All them had hemodynamically significant asymptomatic unilateral carotid stenosis and underwent internal endarterectomy. Postoperatively, their visual function improved. Mean deviation in perimetry values amplitudes pattern evoked potentials increased....

Using Doppler ultrasonography, we evaluated the frequency and severity of carotid artery stenosis in 261 patients with carotid ischemic strokes, 813 patients with carotid transient ischemic attacks, 500 patients with asymptomatic neck bruits, and 500 controls. Most patients with strokes and transient ischemic attacks had no associated carotid artery disease (55% and 64%, respectively), and such...

Background and Purpose The use of three methods of measuring carotid stenosis, which produce different values on the same angiograms, has caused confusion and reduced the generalizability of the results of research. If the results of future studies are to be properly applied to clinical practice, and if noninvasive methods of imaging are to be properly validated against angiography, a single, s...

Duplex ultrasound criteria use a combination of velocity measurements to evaluate internal carotid artery (ICA) stenosis. These evaluations divide ICA stenosis into broad categories. The aim of this study was to design an artificial neural network (ANN) capable of predicting the exact degree of ICA stenosis based on duplex velocity measurements. Consecutive patients with significant carotid ath...

This study aimed to compare the clinical value of carotid ultrasound and digital subtraction angiography (DSA) for artery stenosis in patients with cerebral infarction. Sixty infarction underwent DSA. Carotid stenosis, degree (mild, moderate, severe, occlusion), plaques were recorded compared. rate was 96.67 % (58/60) 91.67 (55/60) on DSA ultrasound, respectively, difference not statistically s...

BACKGROUND AND PURPOSE The aim of this study was to determine the potential value of carotid artery calcification observed on plain radiographs in patients referred for carotid angiogram in the diagnosis of carotid artery stenosis. METHODS One hundred sixty consecutive patients with suspected carotid artery stenosis underwent both plain radiographs of the carotid arteries and digital subtract...

Despite a decline during the recent decades in stroke-related death, the incidence of stroke has remained unchanged or slightly increased, and extracranial carotid artery stenosis is implicated in 20%-30% of all strokes. Medical therapy and risk factor modification are first-line therapies for all patients with carotid occlusive disease. Evidence for the treatment of patients with symptomatic c...

OBJECTIVES The goal of this study was to determine whether carotid angioplasty and stenting (CAS) is equivalent to carotid endarterectomy (CEA) in patients with symptomatic carotid stenosis >70% by a randomized, controlled trial in a community hospital. BACKGROUND Carotid angioplasty and stenting has been suggested to be as effective as CEA for treatment of symptomatic carotid artery stenosis...

Background and Purpose: The aim of this study was to determine the potential value of carotid artery calcification observed on plain radiographs in patients referred for carotid angiogram in the diagnosis of carotid artery stenosis. Methods: One hundred sixty consecutive patients with suspected carotid artery stenosis underwent both plain radiographs of the carotid arteries and digital subtract...
