Patent foramen ovale as a cause of cryptogenic ischemic stroke

A patent foramen ovale from an anatomical and physiological point of view is a normal communication between the atria, which present in utero allows oxygenated placental blood to reach fetal arterial circulation. With incomplete postpartum fusion primary secondary septa, formed. In last two decades, clinical interest problem dictated by fact that its role development such syndromes as ischemic stroke, myocardial infarction, pulmonary embolism, migraine decompression sickness divers has been established, well introduction endovascular techniques for transcatheter closure atrial septal defect. It was found frequency detection patients with cryptogenic stroke on average 2 times higher than established cause ranges 40% 50%. Aim study. Raising awareness neurologists about causes, pathogenetic mechanisms development, methods diagnosis treatment ovale. Material methods. To achieve this goal, results scientific research devoted risk factor were analyzed. The literature search carried out electronic engines Scopus, eLibrary, PubMed using keywords: «ischemic stroke», «cryptogenic «patent ovale», «pathogenesis stroke». Scientific articles published 1878 2021 selected analysis. 31% analyzed works are not older 5 years. Conclusion. etiologically associated stroke. Possible include situ thrombosis, paradoxical arrhythmias. Transcatheter signs high cerebrovascular events combination antiplatelet therapy indicated aged 18 60 years optimal means prevention
