BACKGROUND: Coronary artery bypass surgery with cardiopulmonary bypass carries a
significant risk of perioperative brain injury. At least 1% to 5% will suffer a stroke, and at 3 …

A longitudinal study of cognitive function after coronary artery bypass surgery examined 107
participants using 11 tests, preoperatively and at 6 days, 8 weeks, and 5 years after surgery …

Objective. To investigate changes in cognitive function following carotid endarterectomy
(CEA). Design. Prospective study with controls. Methods. CEA patients (n= 159) were …

Background—Microembolic signals (MES) as detected by transcranial Doppler ultrasound
define an individual stroke risk in patients with carotid artery disease. To study the …

Objectives–To determine whether particular carotid plaque features on ultrasound are more
likely to produce microembolic signals (MES). Patients and methods–We have reviewed 71 …

Cardiac right‐to‐left shunts (RLSs) can be detected by echo‐cardiography and transcranial
Doppler ultrasound (TCD). In patients without adequate transtemporal bone windows …

OBJECTIVE: Left ventricular assist devices have become an established method to bridge
patients with end-stage cardiac failure to heart transplantation. Besides infection and …

Objective: High intensity transient signals (HITS) observed during extracorporeal circulation
and following mechanical valve replacement are suspected of causing cognitive dysfunction …

ABSTRACT Background and Purpose. There is no information about the optimal position of
a patient for the performance of a transcranial Doppler (TCD) examination to detect patent …

ABSTRACT Background and Purpose. Usually, microembolic signal (MES) monitoring is
performed for MESs arising from downstream sources. The aim of this study is to describe …
