Background The distal-balloon protection system is being evaluated for its efficacy in
preventing embolic neurological events during carotid stenting (CAS). We sought to …

Objective: To investigate the frequency of middle cerebral artery (MCA) stenosis in a series
of nonselected patients and the coexistence of microembolic signals with stenosis. Methods …

Although some forms of neurophysiologic monitoring have been used for nearly half a
century in these procedures, 1 their routine application is uncommon. There are several …

Background—l-Arginine reduces platelet aggregation and adhesion in ex vivo studies, but
there is no evidence as yet that it has a therapeutic effect on clinical end points. Doppler …

Background and Purpose—Patent foramen ovale (PFO) is a frequent finding in young
patients with stroke. The aim of this study was to assess whether PFO is a family trait …

Background and Purpose—Transcranial Doppler (TCD) can detect high-intensity transient
signals (HITS) in the cerebral circulation. HITS may correspond to artifacts or solid or …

The role of transcranial Doppler ultrasonography (TCD) in individual risk assessment of
embolic complications and the development of prevention strategies during coronary …

Abstract Background and Purpose: There are few data on the occurrence of microembolic
signals (MES) in patients with lone atrial fibrillation (LAF). The aim of this work was to …

Objectives: Cerebral microembolisation still occurs during cardiopulmonary bypass and may
cause both stroke and postoperative cognitive impairment. We investigated the frequency of …

Objectives: We prospectively evaluated the effects of head position during cardiac deairing
on the Doppler ultrasonography–detected cerebral microemboli in children and the …
