Thrombosis of the Internal Jugular Vein Associated with Severe Ovarian Hyperstimulation Syndrome

Ovarian hyperstimulation syndrome (OHSS) especially in its severe form is a potentially life-threatening complication of exogenous gonadotrophin therapy. Thromboembolism involving the leg veins and also major veins of the upper extremity has been previously associated with OHSS (14). Whilst venous compression due to enlarged ovaries and ascites coupled with immobilization were implicated as the major aetiological factors in lower extremity thrombosis, aetiology of jugular vein or subclavian vein thrombosis is less clear. We herein report a case of internal jugular vein thrombosis in a woman with severe OHSS.
