The entity of cerebrovascular diseases associated with the use of oral contraceptives is well known but quite rare in Japan in contrast to Western countries. We recently encountered a 38 years old female with cerebral venous thrombosis considered to be caused by oral contraception. This patient took oral contraceptives for 17 days following therapeutic abortion, and was transferred to our hospital because of disturbed consciousness. ⋯ There was no relationship between the dose of estrogen and the onset of cerebrovascular diseases. We believe that the onset of this pathological state is based on gynecological hypercoagulable state, and the oral contraception may play a role of a trigger. Oral contraception should be contraindicated in patients with gynecological hypercoagulable state, hypertension and/or smoking habit.
