Patent Foramen Ovale in Cerebral Infarction
Recent studies support the hypothesis of a close aetiological and pathogenic association between the presence of patent foramen ovale (PFO) and cryptogenic stroke. The therapeutic options currently used in the treatment of these patients range from standard antiaggregation and standard-dose anticoagulation to the percutaneous occlusion of the PFO. The use or recommendation of treatment is based...
متن کاملEmbolic distribution through patent foramen ovale demonstrated by (99m)Tc-MAA brain SPECT after Valsalva radionuclide venography.
UNLABELLED Cryptogenic stroke might relate to paradoxical embolism stemming from right-to-left shunt caused by patent foramen ovale (PFO). We performed radionuclide venography using the Valsalva maneuver, followed by (99m)Tc-macroaggregated albumin (MAA) brain SPECT to investigate the fate of emboli originating from the lower extremities. METHODS Ten patients (9 men, 1 woman; mean age, 61 +/-...
متن کاملFatal cerebral fat embolism associated with a patent foramen ovale
Fat embolism syndrome (FES) has been recognized for more than 100 years, but controversy remains with regard to the mechanism of systemic fat embolism. We report a case of healthy 30-years-old men who developed respiratory failure and brain death within 48 h of bilateral tibial fractures. Autopsy showed fat embolism in the lung and brain, and a large patent oval foramen that may have contribute...
متن کاملFatal cerebral fat embolism associated with a patent foramen ovale.
A healthy 22-year-old woman developed respiratory failure and brain death within 48 h of bilateral tibial fractures. Autopsy showed fat embolism in the lung and brain, and a large patent foramen ovale that may have contributed to massive cerebral fat embolism.
متن کامل"interventional closure of patent foramen ovale (pfo) with amplatzer pfo occluder in patients with paradoxical cerebral embolism "
background: percutaneous transcatheter closure has been proposed as an alternative to surgical closure or long-term anticoagulation in patients with presumed paradoxical embolism and patent foramen ovale (pfo). methods: there were two symptomatic patients (29 and 47 years old) who underwent percutaneous transcatheter closure of pfo after at least two events of cerebral ischemia; one embolic eve...
