BACKGROUND AND PURPOSE The inter-relation between the size of patent foramen ovale (PFO) by transesophageal echocardiography (TEE) and the amount of microembolic signals (MES) on transcranial doppler (TCD) is still not determined. METHODS The study group comprised of 104 patients with first-ever ischaemic stroke or transient ischemic attack (TIA). Three(More)
BACKGROUND Carotid disease complicated by thrombosis or embolism is a frequent cause of acute ischemic stroke. The aim of the study was to determine factors associated with carotid disease in patients suffering from acute ischemic stroke in northern Israel. METHODS Participants were 1378 acute ischemic stroke patients, including 671 patients with and 707(More)
BACKGROUND There is limited information about distribution of etiologies of ischemic stroke in different age groups. MATERIALS AND METHODS In this study, we applied the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) classification in 87 patients aged < or = 45, and in 347 patients aged 46-60 years with first-ever ischemic stroke in order to follow(More)
BACKGROUND Ethnic differences among first primary intracerebral hemorrhage (PICH) patients in an Israeli biethnic population have not yet been studied. PATIENTS AND METHODS We included in the study 546 patients (counting warfarin-related hemorrhages) hospitalized during the period from December 1999 through June 2008. RESULTS The mean age was 71.1 +/-(More)
Cognitive decline has recently been found to be associated with microemboli in cerebral vessels in patients with artificial heart valves. The authors sought to determine the nature of such microemboli, that is, whether they are gaseous or solid, by comparing their characteristics to those of artificially generated air emboli in patients with patent foramen(More)
BACKGROUND AND PURPOSE Middle cerebral artery stenosis is not frequent but a well-established cause of first and recurrent ischemic stroke. Our aim was to investigate middle cerebral artery stenosis in the biethnic (Jewish and Arab) population of patients with acute ischemic stroke and transient ischemic attack in northern Israel. MATERIALS AND METHODS(More)
The significance of low-intensity microembolic signals (MES), as well as their relationship with high-intensity MES, has not yet been studied. We monitored MES by TCD in 256 arteries of 229 patients with carotid stenosis. All microemboli were detected automatically without a preliminary set threshold. For those 110 patients who evidenced any emboli, the(More)
PURPOSE The purpose of the study is to investigate the embolic potential as well as ultrasonic characteristics of plaques in patients presenting with severe unilateral restenosis at least 1 year after carotid endarterectomy (CEA), compared with patients with severe unilateral primary carotid stenosis. METHODS We used transcranial Doppler (TCD) to monitor(More)
