A case of an acardiac acephalic monster is described, and the literature concerning the incidence, classification and etiology of acardia is reviewed. Acardia is a very rare congenital anomaly occurring in less than 1 in 34600 deliveries. The acardiac monster has been reported only in multiple, monochorionic pregnancies. This bizarre anomalous fetus is sustained in utero by parasitic anastomoses to the circulation of its usually normal co-twin and is therefore not compatible with extrauterine survival. Possibilities for prenatal diagnosis and complications during pregnancy and delivery are considered.
本文描述了一例无心无头畸胎病例，并对有关无心畸形的发病率、分类和病因的文献进行了综述。无心畸形是一种非常罕见的先天性异常，在每34600次分娩中发生率不到1例。无心畸胎仅在多胎、单绒毛膜妊娠中报道过。这种奇异的异常胎儿在子宫内通过与通常正常的双胎之一的循环进行寄生性吻合而得以维持，因此无法宫外存活。文中还考虑了产前诊断的可能性以及孕期和分娩期间的并发症。
