Conjoined twins, known to the layperson as Siamese twins, are a rare and catastrophic obstetric event. With the approximate incidence being 1 in 50,000 births, few physicians practicing obstetrics will have the unfortunate occasion to manage this biologic anomaly. Should this event occur, early diagnosis, close prenatal management, and the proper route of delivery will assure the best possible outcome for mother and both babies. The author describes the anatomic types of conjoined twins, the prenatal diagnosis and management, the route of delivery, and the overall statistical expectation. Under the best of circumstances, a good outcome is rarely achieved, but the obstetric goal should be a healthy mother and two salvageable babies.
联体双胎，外行人称为暹罗双胎，是一种罕见且严重的产科事件。其发生率约为每50000例出生中有1例，很少有产科医生会不幸遇到这种生物学异常情况需要处理。如果发生这种情况，早期诊断、密切的产前管理以及合适的分娩途径将确保母亲和两个婴儿获得尽可能好的结果。作者描述了联体双胎的解剖类型、产前诊断与管理、分娩途径以及总体统计预期。在最好的情况下，也很少能取得良好的结果，但产科的目标应该是让母亲健康，两个婴儿能够救治。
