Abstract:
ABSTRACT: A heterotopic pregnancy is defined as the presence of a combined intrauterine and ectopic pregnancy. Heterotopic pregnancy is rare, estimated to occur in 1/30,000 pregnancies. It is also reported to be as high as 1% after the use of assisted reproductive technology. Simultaneous extra and intrauterine pregnancy after the induction of ovulation with clomiphene citrate has been reported. Clomiphene citrate which increases the rate of twining could be associated with a heterotopic pregnancy rate of 1/900, which is much less than using assisted reproductive technology. Heterotopic pregnancies are diagnostic and therapeutic challenges for obstetricians. If they continue without diagnosis, a life- threatening situation may occur even when surgical intervention with laparotomy is performed.
