Abdominal gestation is a relatively uncommon complication of pregnancy. Previous reports describe a high incidence of fetal deformations and mortality as well as maternal mortality. A case of twin abdominal gestation is presented and the literature concerning abdominal pregnancy since 1809 is reviewed. The survival rate of liveborn infants of 30 or more weeks gestation was 63%. The maternal mortality rate since 1809 was 18.2%, but this has decreased to 4.5% during the last 20 years. The combined rate of malformations and deformations in the infants was 21.4%. The most common deformations observed were facial and/or cranial asymmetry and various joint abnormalities. Among the most common malformations were limb deficiency and central nervous system malformations. Proposed mechanisms of compression and vascular disruption are discussed.
腹腔妊娠是一种相对罕见的妊娠并发症。既往报道显示胎儿畸形、死亡以及孕产妇死亡的发生率很高。本文报告了一例双胎腹腔妊娠病例，并对自1809年以来有关腹腔妊娠的文献进行了综述。妊娠30周及以上活产婴儿的存活率为63%。自1809年以来孕产妇死亡率为18.2%，但在过去20年中已降至4.5%。婴儿畸形和变形的综合发生率为21.4%。观察到的最常见变形为面部和/或颅骨不对称以及各种关节异常。最常见的畸形包括肢体缺损和中枢神经系统畸形。文中讨论了推测的压迫和血管破坏机制。
