One of the serious conditions complicating the use of hormonal contraceptives are coagulopathies which lead to the development of deep venous thromboses of the lower extremities and embolization into the pulmonary artery. Thrombopathies may however develop in young women at unusual sites, most frequently intracranially - then the neurological symptoms may be ascribed to a different etiology. In the submitted paper the authors present cases with complications of hormonal therapy examined at the Radiodiagnostic Clinic in Plzeň in 1997 to 1999 - twice isolated thrombosis of the deep veins of the leg, four times pulmonary embolization and four times intracranial venous thrombosis.

        Key words: hormonal contraception - pulmonary embolization - deep venous thrombosis - cerebrovascular attack
