Objectives: After studying the article entitled “Sonographic Detection of a Heterotopic Pregnancy in Natural Conception,” you will be able to:
Differentiate heterotopic from an ectopic pregnancy
Determine the likelihood of a heterotopic pregnancy based on patient history
Describe the role of sonography in the diagnosis of heterotopic pregnancy
The prevalence of heterotopic pregnancy is highest with Natural conception Ovulation induction Embryo transfer In vitro fertilization
In natural conception, the prevalence of heterotopic pregnancy is approximately 1 in 100 1 in 300 1 in 10,000 1 in 30,000
In the nonpregnant female, the level of beta human chorionic gonadotropin should be less than 5 mIU/mL 10 mIU/mL 50 mIU/mL 100,000 mIU/mL
A heterotopic pregnancy is defined as A twin gestation, one male and one female Simultaneous implantation of two ova in the uterine cavity Simultaneous implantation of two ova, one within and one outside the uterine cavity An ectopic pregnancy involving the cervix
The detection rates of heterotopic pregnancy reported for transvaginal sonography vary from approximately 40% to 80% 30% to 50% 20% to 40% 10% to 20%
When detected by transvaginal sonography, the mean gestational age for heterotopic pregnancy has been reported to be 6 weeks 8 weeks 10 weeks 12 weeks
The most common symptom/finding associated with heterotopic pregnancy is Peritoneal irritation Abdominal pain An enlarged uterus An adnexal mass
The treatment used most frequently to manage heterotopic pregnancy is Spontaneous abortion of the intrauterine gestation Medical treatment Surgical removal of the ectopic gestation Surgical removal of all gestations
Heterotopic pregnancy is identified preoperatively in approximately 10% of cases 20% of cases 25% of cases 30% of cases
With proper management of heterotopic pregnancy, a good outcome is achieved in approximately One-fourth of cases One-third of cases One-half of cases Two-thirds of cases
