Internal jugular vein thrombosis after ovulation induction with gonadotropins.

ABSTRACT

An unusual case of ovarian hyperstimulation syndrome complicated by internal jugular vein and mediastinal thrombosis is presented. Hemoconcentration and perhaps immobilization appear to be the most probable causative factors. The patient was successfully treated with heparin anticoagulation. An uneventful twin pregnancy resulted from the stimulation cycle.
