Kim JA, Cho JY, Lee YH, Song MJ, Min JY, Lee HJ, Han BH, Lee KS, Cho BJ, Chun YK - Korean J Radiol (2003 Jan-Mar)

Bottom Line: Multifetal gestations are high-risk pregnancies involving higher perinatal morbidity and mortality, and are subject to unique complications including twin oligohydramnios-polyhydramnios sequence, twin-to-twin transfusion syndrome, acardiac twins, conjoined twins, co-twin demise, and heterotopic pregnancies.The purpose of this study is to describe the prenatal ultrasonographic and pathologic findings of these complications.

Ultrasonographic findings of a cornual heterotopic pregnancy.A. Ultrasonogram obtained at gestational age 7 weeks shows a gestational sac (black arrow) with an embryo (arrowhead) within the uterine cavity.B. In the cornual portion of the uterus, a coexisting gestational sac (arrows) with an embryo (arrowhead) is visible.

Figure 6: Ultrasonographic findings of a cornual heterotopic pregnancy.A.

In the cornual portion of the uterus, a coexisting gestational sac (arrows) with an embryo (arrowhead) is visible.

Mentions: A heterotopic multiple pregnancy is one in which an intrauterine pregnancy and ectopic gestation coexist, and due to the dramatic increase in fertility treatments such as ovulation induction and assisted reproductive technology, the incidence of the condition has increased dramatically, during ovulation induction, for exampl it is now about 1%. In an intrauterine pregnancy, sonographic detection of an extrauterine gestational sac, with or without a fetal pole, confirms the diagnosis (Fig. 6). The most frequent location is the ampulla of the fallopian tube, followed by the isthmus and fimbria. The prognosis of an intrauterine pregnancy is similar to one without heterotopia (14).
