Involuntary movements developed in five women taking oral contraceptives. In one, the sudden onset of a unilateral disturbance suggested a cerebral thrombosis; this case is considered to be a further example of the increased risk of cerebrovascular disease associated with oral contraception. The four other patients suffered a relapse of Sydenham's chorea between one and four months after starting an oral contraceptive regimen. Possibly an underlying vascular mechanism was responsible for these relapses.
五名服用口服避孕药的女性出现了不自主运动。其中一名女性突然出现单侧功能障碍，提示脑血栓形成；该病例被认为是口服避孕药相关的脑血管疾病风险增加的又一实例。另外四名患者在开始口服避孕药治疗方案后的一至四个月内，出现了Sydenham舞蹈病复发。这些复发可能是由潜在的血管机制引起的。
