The problems of diagnostic embolic strokes are discussed. We set out the algorithm for identifying patients, in whom patent foramen ovale is the most probable cause of embolic stroke. Detailed consideration of imaging diagnostic methods possibility is included. Hypothesis of probable source of cardioembolism from patent foramen ovale is presented. Recommendations for the secondary prevention of recurrent ischemic stroke, associated with patent foramen ovale, are provided. We also considered the issues of antithrombotic treatment.</p></abstract><trans-abstract xml:lang="ru"><p>Представлен клинический разбор пациентки молодого возраста с рецидивирующими ишемическими инсультами. Обсуждаются проблемы диагностики эмболических инсультов. Изложена методика обнаружения пациентов, у которых открытое овальное окно является наиболее вероятной причиной эмболического инсульта, в том числе подробно рассмотрены возможности визуализирующих методов диагностики. Освещена гипотеза возможного источника кардиоэмболии при открытом овальном окне. Даны рекомендации по вторичной профилактике ишемического инсульта, ассоциированного с открытым овальным окном.
