One hundred patients with asymptomatic carotid bruit or transient ischemic attack (TIA) underwent continuous-wave Doppler (CWD) and real time ultrasound (RTU) testing of their cervical carotid arteries. After ultrasonic studies, 51 patients also underwent bilateral carotid angiography. There was 95% agreement between CWD and angiography for the diagnosis of a significant (greater than 50%) sten...

Background and Purpose A nested case-control analysis of data collected during the prospective Royal College of General Practitioners' Oral Contraception Study was performed to examine the relation between use of oral contraception and risk of stroke. Methods The 253 women who had a first-ever stroke (International Classification of Diseases, eighth revision, codes 4300 to 4389) or amaurosis fu...

Carotid artery stenosis (CAS) is one of the major complications of external irradiation (radiotherapy, RT) for laryngeal carcinoma. Considering amaurosis fugax is often one of the first signs of significant CAS our focus was to determine weather patients with post-irradiation CAS also develop ocular microangiopathy as a result of insufficient ophthalmic circulation. In our study Carotid Duplex ...

A 66-year-old man with cryptogenic ischemic stroke and multiple acute ischemic lesions in the right middle cerebral artery territory was enrolled in the CAPIAS trial (Carotid Plaque Imaging in Acute Stroke; NCT01284933). Baseline carotid MRI demonstrated a right-sided nonstenotic American Heart Association type-VI plaque with a large lipid/necrotic core and intraplaque hemorrhage (figure 1). El...

Carotid artery disease is an important cause of mortality and morbidity related to atherosclerosis. Recently, percutaneous intervention procedures have been widely used to treat atherosclerotic carotid artery disease. We report the case of a 57-year-old male patient with a history of acute amaurosis fugax. Carotid angiography was performed as blood pressure differed between his left and right a...

Materials and methods During a 7 year period from October 2000 to April 2007, 84 symptomatic carotid stenosis were treated at Department of general surgery of AUO “Federico II” of Naples 48 with CAS and 36 with CEA. We divided our patients in two group not randomly but according to valuation anesthesia. The age range in this group was 80 to 89 years (average age of 82.7 years). The indication f...

OBJECTIVE The outcomes of carotid angioplasty and stenting (CAS) are, in addition to patient baseline characteristics, highly dependent on the safety of the endovascular procedure. During the successive stages of CAS, transcranial Doppler (TCD) monitoring of the middle cerebral artery was used to assess the association of cerebral embolism and hemodynamic changes with transient (amaurosis fugax...

PURPOSE To determine the optimal peak systolic velocity (PSV) threshold at duplex ultrasonography (US) required to establish the need for carotid endarterectomy in symptomatic patients on the basis of the long-term cost-effectiveness outcomes of diagnostic testing and subsequent treatment. MATERIALS AND METHODS From January 1997 through January 2000, a prospective medical ethics committee-app...
