Percutaneous transluminal angioplasty (PTA) is being extensively applied to treat arteriosclerotic lesions. However, this application has not been widely accepted for the treatment of carotid artery stenosis. Successful attempts to relieve cerebral ischemia from extracranial carotid arterial stenosis by PTA are reported. Twenty-seven patients with arteriosclerotic stenosis, fibromuscular diseas...

background and aims. the purpose of this study was to identify patients at the risk of cerebrovascular attack (cva) by detecting calcified carotid artery atheroma (ccaa) in panoramic radiography and evaluating their risk factors. materials and methods. a total of 960 panoramic radiographs of patients above 40 years old ‎were evaluated. doppler sonography (ds) was performed for patients who show...

BACKGROUND Previous studies demonstrated a modest association between C-Reactive Protein (CRP), stenosis of carotid artery, and carotid Intima-Media Thickness (IMT) in general population. During present study, we aimed to evaluate the relationship between High Sensitivity C-Reactive Protein (hsCRP) and Common Carotid Intima-Media Thickness (CCIMT) in patients who candidate for Coronary Artery B...

We prospectively studied the results of carotid angiography in 45 patients with transient or nondisabling neurologic deficits caused by lacunar infarction in the internal capsule or corona radiata and demonstrated by computed tomography. An ipsilateral stenosis at the bifurcation of the internal carotid artery was found in 14 patients (31%, 95% confidence limits 18-47%), seven of whom also had ...

BACKGROUND Carotid artery stenting has recently been recommended as an alternative to carotid endarterectomy by some clinicians. OBJECTIVE To evaluate success rate, as well as in-hospital and 30-day adverse events in our first experience in Iran for carotid artery stenting with protection devices. METHODS From December 2003 through July 2004, we performed 12 consecutive (9 males and 3 femal...

BACKGROUND The object of this study was to investigate the potential role of FGF23 on plaque stability in type 2 diabetic patients with internal carotid artery stenosis. METHODS In this retrospective observational study, we analyzed FGF23 serum level in 361 type 2 diabetic patients with internal carotid artery stenosis undergoing carotid endarterectomy and in 598 diabetic controls without car...

We prospectively studied the results of carotid angiography in 45 patients with transient or nondisabling neurologic deficits caused by lacunar infarction in the internal capsule or corona radiata and demonstrated by computed tomography. An ipsilateral stenosis at the bifurcation of the internal carotid artery was found in 14 patients (31%, 95% confidence limits 18-47%), seven of whom also had ...

BACKGROUND Renovascular disease is the most frequently encountered secondary cause of hypertension and is one of the few potentially reversible causes of chronic renal failure. These patients are at increased risk of having cerebrovascular events following operative management for atheromatous renal-artery stenosis. We studied the prevalence of carotid-artery disease in patients with atheromato...

CONTEXT Therapeutic trials generally have not distinguished outcomes of stroke according to cause. OBJECTIVE To determine whether stroke and subsequent disability was of large-artery, lacunar, or cardioembolic origin in patients with different degrees of symptomatic and asymptomatic carotid stenosis. DESIGN Observational study of prospective data collected from the North American Symptomati...

Carotid artery stent placement, performed for correction of an asymptomatic severe stenosis, leads to the resolution of persistent and troublesome pulsatile tinnitus. Tinnitus has been reported as a consequence of severe carotid stenoses on previous occasions. This case highlights how an aberrant occipital artery originating above a carotid artery stenosis can result in flow reversal and be a m...
