[Thromboembolic complication after ovarian stimulation]

We report on two pregnant women with dyspnoe and thoracic pain in the context of an ovarian hyperstimulation syndrome.

Both patients had pleural effusions. The first patient was diagnosed with pulmonary embolism via computer tomography. In the second patient, thrombosis of the upper part of the body including intracranial thrombosis was revealed via magnetic resonance and ultrasound imaging. In both cases, thrombosis was caused by ovarian hyperstimulation.

Therapy included anticoagulation with low molecular weight heparin and a drainage of the pleural effusions. One patient had an abortion in the 8th week of pregnancy, the second patient gave birth to two healthy children.

Ovarian hyperstimulation syndrome is a potentially life-threatening disease, which should be considered as a differential diagnosis of causes of thromboembolic events in early pregnancy.
