OBJECTIVE To describe the prevalence at baseline and the 5-year incidence of retinal emboli, associated risk factors, and the relationship of retinal emboli at baseline to stroke and ischemic heart disease mortality. METHODS The Beaver Dam Eye Study is a large (N = 4926) population-based study of persons aged 43 to 86 years at the baseline examination. Retinal emboli were detected at baseline...
BACKGROUND AND PURPOSE Although thromboembolic stroke is caused by red, white, or mixed clots, the emboli previously used in animal studies on thrombolysis were more often red than white. Because this might be one of the reasons why thrombolysis is less effective in patients than in experimental stroke, we developed a new method of preparing highly standardized red and fibrin-rich white emboli....
Fifteen dogs were studied by perfusion scan, angioscopy and autopsy. In 10, emboli were formed in leg veins and released before study; five dogs were not embolized and served as controls. In controls, angioscopy disclosed no emboli, perfusion scans were normal after angioscopy and autopsy disclosed no emboli. Among the embolized dogs, 23 emboli were identified at autopsy. Perfusion scans disclo...
BACKGROUND The vascular depression hypothesis and our recent findings of increased frequency of spontaneous cerebral emboli in dementia suggest that such emboli may be involved in the causation of depressive symptoms in dementia. AIMS To evaluate the association between spontaneous cerebral emboli and depressive symptoms in Alzheimer's disease and vascular dementia. METHOD In a cohort of 14...
Fat mobilization during cardiopulmonary bypass (CPB) is a recognized risk of the procedure. Intravascular mobilization of fat emboli subsequent to CPB has been implicated in some of its recognized pathophysiologies, particularly with regard to cerebral embolic injury. The aim of this study was to investigate whether fat mobilization is still a real issue in modern perfusion practice and to dete...
BACKGROUND Thermal ablation is one of the most commonly used modalities to treat central airway obstruction. Both laser and argon plasma coagulation (APC) have been reported to cause gas emboli and cardiac arrest. We sought to determine whether bronchoscopic ablation therapy can result in systemic gas emboli, correlate their presence with the rate of gas flow, and establish whether a zero-flow ...
