[A young woman with fulminant pulmonary embolism].

We describe the case of a 24-year-old woman who was admitted to the emergency department with dyspnea and sinus tachycardia. The suspected diagnosis of pulmonary embolism was confirmed by computed tomography (CT) scan. The patient lost consciousness soon afterwards and was found to be pulseless. Cardiopulmonary resuscitation was performed and high dosis thrombolysis was given. The patient survived without sequelae and was discharged on oral anticoagulation from the hospital 8 days after the initial admission. In our opinion unknown factor-V Leiden in combination with a local form of hormonal contraception (NuvaRing®) was responsible for the deep venous thrombosis of the left leg and the pulmonary embolism.
