A case of craniopagus parasiticus is described in which the parasitic twin is more fully developed anatomically than in any of the previous reports. Somatic and placental vascular anastomoses between the twins and hypoplasia of the umbilical cord of the parasite were also observed. These findings support the hypothesis that craniopagus parasiticus results from compromise of the blood supply to one of a pair of craniopagus conjoined twins.
本文描述了一例寄生性联体双胎病例，其中寄生胎在解剖学上比以往任何报告中的都发育得更完全。还观察到双胞胎之间的体循环和胎盘血管吻合以及寄生胎脐带发育不全。这些发现支持了以下假说，即寄生性联体双胎是由于一对颅骨联体双胎中一个的血液供应受到损害所致。
