Massive deep vein thrombosis in a patient with antithrombin III deficiency undergoing ovarian stimulation for in vitro fertilization

Abstract

We stress the importance of obtaining a thorough personal and family history before initiation of ovarian hyperstimulation. Measuring activity of AT III, protein C, and protein S in patients with a suspicious history of thromboembolic episodes occurring at an early age may lead to the implementation of appropriate prophylactic measures, preventing potentially life-threatening complications.
