Cerebral infarction is a major health problem. The two most common causes are atherosclerosis (30 to 35%) and cardio-embolic origin (35 to 40%). However, in 25% of cases the cause is undetermined, known as cryptogenic stroke or stroke of undetermined origin. Paroxysmal Atrial Fibrillation appears to cause a significant proportion of these cryptogenic cerebral infarctions. One of the major challenges in the management of cerebral infarctions is the prevention of recurrence. If the cause is atheromatous, treatment is based on platelet antiaggregants and the correction of cardiovascular risk factors. If the cause is atrial fibrillation, the treatment of choice is anticoagulation therapy. Cryptogenic strokes are managed with antiplatelet therapy. In past studies, the thrombi responsible for cerebral infarctions have been analyzed anatomopathologically to see if the composition of the thrombi could help identify the cause of the cerebral infarction. These studies have proved to be contradictory. The composition of the bacterial flora of cerebral infarct thrombi has not yet been studied, apart from some limited data on septic emboli. In myocardial infarction, the cause of which is almost exclusively atheromatous, bacteria of the periodontal flora have been detected in thrombi of ST-segment elevation infarctions. The causes of cerebral infarction are multiple. The hypotheses explored in this study are that there are differences in the composition of the bacterial flora of the thrombus depending on whether the cause is atheromatous or cardio-embolic and that the study of the composition of the thrombus could be used to identify the cardio-embolic cause in patients with cryptogenic cerebral infarction.
