There has been a controversy over data of thrombolytic and endovascular surgical treatment about cerebral infarction secondary to infective endocarditis. We report a woman who received early mechanical embolectomy as a treatment of acute stroke with infective endocarditis. A 35-yr-old woman was hospitalized due to right hemiparesis. Brain image showed cerebral infarction at the middle cerebral ...

Systemic air embolism is known to rarely complicate blunt chest trauma. However, cerebral infarction caused by air emboli possibly originating from a traumatic pneumatocele has not been previously reported. We report a case of a 46-year-old woman who sustained blunt chest trauma with multiple rib and clavicular fractures, hemothorax and a huge, tense traumatic pneumatocele. She subsequently dev...

BACKGROUND Neurocognitive impairment can be a debilitating complication after coronary artery bypass graft surgery (CABG). Cardiopulmonary bypass, in particular, cerebral emboli, has been implicated. We compared neurocognitive function and cerebral emboli in patients undergoing on-pump and off-pump CABG. METHODS 212 patients admitted for CABG were randomly assigned to on-pump (n = 104) or off...

BACKGROUND AND PURPOSE There are concerns that cardiac catheterization may cause retinal embolization, a risk marker for cerebrovascular emboli and stroke. We describe the incidence of acute retinal embolism after cardiac catheterization. METHODS One hundred unselected patients attending a tertiary referral center for diagnostic cardiac catheterization were recruited. Digital retinal photogra...

BACKGROUND The main indication for carotid endarterectomy (CEA) is severity of carotid artery stenosis, even though most strokes in carotid disease are embolic. The relationship between carotid plaque volume (CPV) and symptoms of cerebral ischaemia, and the measurement of CPV by minimally invasive tomographic ultrasound imaging, were investigated. METHODS The volume of the endarterectomy spec...

Considerable variation exists in the interplay of the factors influencing the occurrence of strokes and their final outcome. A final statement about the usefulness of anticoagulant drugs in the treatment of cerebrovascular disease must await further study. The current indications for their use include: (1) intermittent insufficiency of the basilar arterial system, (2) intermittent insufficiency...

A striking similarity has been found between the distribution of occlusions in various cerebral arteries and the statistical regularity of the pathways of balloon drifting freely in the blood stream. Based on the assumption that the course of a balloon is determined by the same hydrodynamic laws as that of an embolus of similar size, it is concluded that the majority of occlusions of the cerebr...

Carbon dioxide embolism is a rare but potentially devastating complication of laparoscopy or hysteroscopy, t' 2 Embolic sequelae include cardiac arrest, pulmonary oedema, and neurological impairment due to anoxia or cerebral embolization. 3' 4 The following is a report of a patient who developed these complications after carbon dioxide insufflation for laparoscopy. The patient's neurological de...

BACKGROUND Neurobehavioral impairment is a common complication of coronary bypass surgery. Cerebral microemboli during cardiopulmonary bypass (CPB) are a principal mechanism of cognitive injury. The aim of this work was to study the occurrence of cerebral embolism during CPB and to evaluate the effectiveness of evidence-based CPB circuit component and process changes on the exposure of the pati...

The effect of anticoagulation on lesions caused by cerebral emboli of different types was studied in 57 dogs. The resultant arterial and parenchymal lesions were assessed by pathologic and angiographic studies. Embolization with emboli that caused little or no inflammatory response in the artery (12 dogs) was not associated with hemorrhagic infarcts or with subdural or subarachnoid hemorrhage; ...
