Background and Purpose Doppler ultrasound detection of emboli signals may assist in distinguishing erabolic from thrombotic stroke. Selected patient groups have a high incidence of such signals. We have examined consecutive stroke cases to identify the incidence of Doppler emboli in different etiologic subtypes of stroke. Methods Forty-five patients presenting with first-ever acute carotid terr...

Neuropsychological impairment is a very common complication of cardiopulmonary bypass (CPB). The principal cause of postoperative cognitive impairment is thought to be cerebral microemboli during CPB. We recently investigated the effects of perfusionist interventions and aortic cannulation techniques on cerebral emboli production during coronary bypass (CABG) surgery. Patients undergoing isolat...

BACKGROUND AND PURPOSE Hypertension is commonly considered the major cause of lacunar infarctions. However, in some cases, it has been suggested that lacunes could be caused by cerebral emboli from cardiac or carotid sources. Cholesterol cerebral emboli have been rarely reported as a cause of lacunes. CASE DESCRIPTION We describe a 79-year-old patient with a progressive multi-infarct dementia...

BACKGROUND AND PURPOSE Calcified cerebral emboli are a rarely reported but devastating cause of stroke and may be the first manifestation of vascular or cardiac disease. Our aim was to evaluate the diagnosis, prevalence, imaging appearance, presumed embolic source, treatment, and outcome of patients with calcified cerebral emboli. MATERIALS AND METHODS Our radiology information system was sea...

A 30 year-old man referred to the emergency department with loss of consciousness and a stab wound in the right para-spinal region at about the level of the T6 vertebra. On admission, the patient was confused, agitated, and had automatism in his lips and mouth. There were no obvious signs of head trauma. Vital signs were stable, and lung and abdominal exams were normal. The brain computed tomog...

To cite: Saleh M, Juan E. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2015-210445 DESCRIPTION Isolated cerebral fat emboli syndrome with subtle clinical signs not fulfilling Gurd’s criteria and diagnosed by MRI and CT changes have been previously described. We describe middle cerebral artery Doppler findings (figure 1) in a case of cerebral fat embolism follo...

OBJECTIVE Cardiac surgery is associated with intraoperative cerebral emboli, which can result in postoperative neurological complications. A new ultrasonic transducer (EmBlocker) can be positioned on the ascending aorta and activation of the EmBlocker is expected to divert emboli to the descending aorta, thereby decreasing emboli in the cerebral arteries. In this preliminary animal study, safet...

BACKGROUND AND PURPOSE Many patients who undergo cardiac surgery assisted with cardiopulmonary bypass (CPB) experience cerebral injury, and microemboli are thought to play a role. Because an increased duration of CPB is associated with an increased risk of subsequent cerebral dysfunction, we investigated whether cerebral microemboli were also more numerous with a longer duration of CPB. METHO...

This case reveals a left pulmonary arteriovenous malformation (PAVM) as a cause of recurrent cerebral and cerebellar emboli. Extensive workup excluded other etiologies of emboli formation, and the patient was transferred to a tertiary care center for percutaneous embolotherapy. In the absence of a clear etiology, PAVM should be considered as a potential cause of recurrent cerebral emboli, espec...

BACKGROUND AND PURPOSE Inadvertent foreign body embolization is a rarely diagnosed and neglected complication of cerebral angiography that has not been studied systematically. METHODS We undertook a comprehensive 5-year retrospective study of all available postmortem cases of postangiographic neurologic complications, as well as a comprehensive histologic examination of all surgically resecte...
