Arterial thrombosis in young women after ovarian stimulation: case report and review of the literature.
Both venous and arterial thrombosis have been described in women after ovarian stimulation and/or hyperstimulation for infertility management. The ratio between venous and arterial thrombosis in this condition is about 2 or 3 to 1, contrary to what seen during pregnancy or oral contraception where it is 5 or 10 to 1. An accurate perusal of the literature and of personal files has yielded 34 cases of arterial thrombosis after assisted reproductive technologies (ART) which entailed ovarian stimulation. There were 15 cases of ischemic strokes; 7 cases of carotid and/or vertebral artery occlusion; 6 of aorta and peripheral vessel thrombosis, 2 of mesenteric artery occlusion, 3 with myocardial infarction and 2 with intracardiac thrombosis. Associated risk factors were as follow: smoking in 4 women; antiphospholipid antibodies in 2; decrease in protein S in 1. Furthermore, polycystic ovaries were present in two women. Ovarian hyperstimulation was obtained with several protocols which included human chorionic gonadotropin (HCG) in all but a few instances. Age of women varied between 22 and 41 with an average of 32. Nineteen women were pregnant at the time of thrombosis. Only seven of these 19 pregnancies were brought to term with fetal survival. Abortion was spontaneous in 5 cases and therapeutic in the additional 7. There were two maternal fatalities.
