BACKGROUND Transcranial Doppler monitoring enables the detection of emboli passing through intracranial arteries. Comparison of the different intracranial vessels with respect to emboli detection can be of use in identifying the source of embolism. CASE DESCRIPTION We report the case of a patient with an acute posterior cerebral artery (PCA) infarct on the right side, with evidence for high-d...

We report an unusual case of infective endocarditis (IE) in an 88-year-old woman, occurring on a prolapsing mitral valve and characterized by an atypical vegetation shape resembling a spiral-like appearance. After the patient refused surgical correction, persistent IE despite prolonged antibiotic therapy was observed, resulting in an ischemic stroke probably secondary to septic embolus. The imp...

Fistula Cerebral air embolism is a rare but known complication resulting from intracardiac instrumentation. Although reports of atrioesophageal (AE) fistulas have been documented in clinical journals and the cardiothoracic radiology literature, there has been little focus on the neurologic manifestations and imaging findings of this entity. We report the case of an air embolism presenting 35 da...

Cerebral air emboli have been implicated in the transient neurological deficits seen in patients after cardiovascular surgery. Since perfluorocarbon emulsions such as FC-43 have greater solubilities for gases compared to plasma, it was decided to investigate their potential in providing protection against transient ischemia produced by such emboli. Forty rabbits were divided into three groups o...

Cerebral ischemia of thrombotic or embolic origin is still a major cause of morbidity and m o r t a l i t y, mainly because the cellular mechanisms that lead to primary and secondary brain damage are still incompletely understood. This has stimulated many authors to develop experimental models to study the modification of biological and neurophysiological parameters in cerebral ischemia. The mo...
