[Cerebral ischemic arterial accidents in young adults. 40 cases].

We observed 40 patients aged from 15 to 40 years who suffered either a transient ischemic attack or an arterial ischemic stroke. All patients were clinically and physically examined, i.e. chest-X rays, electrocardiograms, biological tests and C.T. scan or magnetic resonance imaging that confirmed the diagnosis of ischemic cerebral infarction. Most patients underwent echocardiography and angiography. The time span between the onset of the ischemic event and angiography was recorded. A few of them had CSF analysis and determinations of antithrombin III, protein C and protein S. The etiology was confirmed in 15 patients (5 cardioembolic diseases, 7 vasculopathies, 3 coagulopathies). Twenty three had well-known vascular risk factors, but also an increase in serum fibrinogen concentration, which might have been associated with specific predisposing factors: oral contraceptives, patent foramen ovale, migraine, craniocervical trauma, acute alcohol intoxication and infectious diseases. No cause was found in 2 patients. We suggest a practical approach and highlight the value of angiography when performed early in the course of the illness to enhance the percentage of positive diagnosis. About 45 p. 100 of the patients followed-up (mean duration: 3 years) were unable to resume normal professional activity.
