BACKGROUND AND PURPOSE While sensitive to internal carotid artery (ICA) occlusion, carotid ultrasound can produce false-positive results. CT angiography (CTA) has a high specificity for ICA occlusion and is safer and cheaper than catheter angiography, although less accurate. We determined the cost-effectiveness of CTA versus catheter angiography for confirming an ICA occlusion first suggested b...

BACKGROUND AND PURPOSE A major disadvantage of carotid artery stenting (CAS) compared to carotid endarterectomy is the increased risk of cerebral embolism. Thus, establishing a simple method to discriminate fragile plaques on preoperative routine examination is important. The present study examined whether high-intensity signal (HIS) in the plaque on time-of-flight (TOF) MRA, performed for scre...

background: carotid artery stenting is now used as an alternative to surgical endarterectomy. this study was done to assess the feasibility, safety, and immediate and late clinical outcomes in patients undergoing carotid stenting . methods: between july 2008 and december 2009, a total of 40 patients (20 male, mean age: 65 ± 11 years, 19 symptomatic, and 90% high risk for endarterectomy) underwe...

purpose: to compare ipsilateral and contralateral carotid wall thickness in patients with acute unilateral non-arteritic anterior ischemic optic neuropathy (naion). methods: this prospective case series included 17 (10 male and 7 female) patients with unilateral naion of less than 8 weeks' duration who underwent b-mode ultrasonography to measure intima-media thickness (imt) in the common c...

Non-contrast pelvic computed tomography (CT) can detect severe iliac artery calcifications that present technical contraindications to kidney transplantation (TCT). We screened 454 asymptomatic patients with a history of any the following: hemodialysis >10 years, diabetes mellitus >20 coronary disease (CAD) percutaneous or surgical interventions, carotid disease, below-/above-knee amputations, ...

Background: Carotid artery stenosis (CAS) is one of the major causes stroke in coronary bypass grafting (CABG). Aims: The aim this study was to determine which age groups require screening for CAS using carotid duplex ultrasound asymptomatic patients undergoing CABG. Methods: We included 644 neurologically consecutive (mean [SD] age, 63.9 [8.8] years; men, 453 [70.3%]) who underwent elective is...

BACKGROUND Early subclinical atherosclerosis has been mainly researched in carotid arteries. The potential value of femoral arteries for improving the predictive capacity of traditional risk factors is an understudied area. OBJECTIVES This study sought to evaluate the association of subclinical carotid and femoral plaques with risk factors and coronary artery calcium score (CACS) in middle-ag...

D iabetic retinopathy is one of the major complications of diabetes, and it is the most common cause of blindness. Following the recommendation of the management guidelines for type 2 diabetes , we have established a routine screening for diabetic complications in our clinics (1). Although nonmydriatic fundus photography was widely used for screening of diabetic retinopathy, less attention has ...
