[Postpartum bilateral ovarian vein thrombosis and its complications].

A 27-year-old patient died postpartum from pulmonary embolism. The right ovarian vein was found to be the essential source of thrombemboli which could not be stopped by the implantation of a Greenfield umbrella into the vena cava inferior. The additional ligature of both ovarian veins can eliminate this important source of pulmonary embolism in pregnancy and puerperal period.
