Introduction. Heterotopic pregnancy is a rare complication usually seen in populations at risk for ectopic pregnancy or thoseundergoing fertility treatments. It is a potentially dangerous condition occurring in only 1 in 30,000 spontaneous pregnancies.Withthe advent of Assisted Reproduction Techniques (ART) and ovulation induction, the overall incidence of heterotopic pregnancyhas risen to approximately 1 in 3,900 pregnancies. Other risk factors include a history of pelvic inflammatory disease (PID),tubal damage, pelvic surgery, uterine Mullerian abnormalities, and prior tubal surgery. Heterotopic pregnancy is a potentiallyfatal condition, rarely occurring in natural conception cycles. Most commonly, heterotopic pregnancy is diagnosed at the timeof rupture when surgical management is required. Case. This paper represents two cases of heterotopic pregnancies as well as aliterature review. Conclusion. Heterotopic pregnancy should be suspected in patients with an adnexal mass, even in the absenceof risk factors. Clinicians must be alert to the fact that confirming an intrauterine pregnancy clinically or by ultrasound does notexclude the coexistence of an ectopic pregnancy. A high index of suspicion in women is needed for early and timely diagnosis, andmanagement with laparotomy or laparoscopy can result in a favorable and successful obstetrical outcome.

1. Introduction

Heterotopic pregnancy is the simultaneous coexistence ofan intrauterine and an extrauterine gestation [16]. It isa rare and potentially dangerous condition occurring inonly 1 in 30,000 spontaneous pregnancies [712]. With theadvent of Assisted Reproduction Techniques (ART) [1214]and ovulation induction, the overall incidence of heterotopicpregnancy has risen to approximately 1 in 3,900 pregnan-cies [15]. However, obstetricians and emergency medicinephysicians are unlikely to consider this diagnosis as a part ofthe differential in cases presenting with abdominal pain andvaginal bleeding.

Transvaginal ultrasound is the key to diagnosing het-erotopic pregnancy [8, 16]. However, it continues to have

a low sensitivity because the diagnosis is often missed oroverlooked [17, 18]. Therefore the diagnosis is often delayedleading to serious consequences.

Surgical intervention plays a key role in the manage-ment of heterotopic pregnancy [19]. The goal is to removethe ectopic pregnancy without jeopardizing the intrauterinepregnancy [20]. Laparoscopic salpingectomy is the standardsurgical approach of heterotopic pregnancy. Other man-agement options mentioned in the literature include localinjection of potassium chloride, hyperosmolar glucose, ormethotrexate into the sac under ultrasound guidance fol-lowed by aspiration of the ectopic pregnancy [21]. This paperrepresents two cases of heterotopic pregnancies as well asreview of literature.

2. Presentation of the Case Number 1

Patient is a 34-year-old Hispanic female, G3P1011 at 9 weeksand four days by last menstrual period, consistent with a 9weeks and three days sonogram, presented to the emergencyroom complaining of vaginal spotting, lower abdominalpain, and nausea. She denied any leakage of fluid, urinarysymptoms, fever, chills, dizziness, palpations, or any othersymptoms.

The patient had a history of a prior hospitalization forpelvic inflammatory disease (PID) with a retained intrauter-ine device (IUD) about seven years priorly. Her IUD wasremoved in the operating room. Her cultures at that timegrew Actinomyces, Streptococcus viridans, and coagulase neg-ative Staphylococcus and she was treated with Doxycyclineand Ceftriaxone. Patient did not have any other past medical,surgical, or family history.

Upon presentation to emergency department, the patientwas noted to be pale and her abdomen was mildly distendedand was tender more on the right side than left. On vaginalexam, there was no active bleeding or leakage of fluid. Thecervix was found to be closed, long, and posterior, withcervical motion tenderness and bilateral adnexal tenderness.No adnexal masses were appreciated. There were no otherpertinent significant physical findings.

The patients blood type was A Rh positive, with Beta-HCG value of 146,864mIU/mL, which correlates with agestation of six to eight weeks. The progesterone value was28.52 ng/mL, appropriate for an early first trimester preg-nancy. The patients initial hemoglobin was 10.3 g/dL, hemat-ocrit of 30.6%,MCV of 89.1 fL, and RDWof 14.1%. Follow-uphemograms showed a continuous drop in the hemoglobin/hematocrit through 8.7/26.3 to 7.6/22.8.

Pelvic ultrasound (Figure 1) revealed a single liveintrauterine pregnancy of 8weeks and 4dayswith a fetal heartrate of 188 beats per minute (BPM) and an ectopic pregnancywas seen in the right adnexa of 8 weeks and 0 days with a fetalheart rate of 183 bpm.A large amount of free fluidwas present,consistent with the acute blood loss noted in the droppinghemoglobin/hematocrit.

An exploratory laparotomy was performed revealing anapproximately 5 cm 3 cm ruptured ectopic pregnancy at theampulla of the right fallopian tube, as well as an intact ovariancorpus luteal cyst (Figure 2). A right salpingectomy and evac-uation of 300 cc of hemoperitoneum was performed. Histo-pathology confirmed the diagnosis of an ectopic pregnancy.The fetal heart rate of the intrauterine pregnancy was presentbefore and after surgery. The hospital course was uneventfuland the patient struggled with the decision whether to keepthe intrauterine pregnancy or not. Despite the fact that

the intrauterine pregnancy was progressing, the patient wasunconvinced and opted for termination of the intrauterinepregnancy via dilation and curettage on postoperative dayfourteen.

3. Presentation of the Case Number 2

Patient is 32 years old, G1P0 at 7 6/7 weeks by last menstrualperiod of 1/22/14, who initially presented in the ED on 3/16/14with complaining of vaginal bleeding, and she was diag-nosed with complete abortion. On clinic follow-up visit on3/18/14, Beta-HCG level was 22995mIU/mL increasing from20571mIU/mL on 3/16/14. Patient denied any complaintsincluding any vaginal bleeding or abdominal pain on follow-up visit, and she was hemodynamically stable.

An obstetric ultrasound on 3/2/14 (Figure 3) revealedintrauterine gestational sac and subchorionic hemorrhage, aswell as a fetal pole measuring approximately 2.9mm with nofetal cardiac activity at that time (Figure 3).

Repeat ultrasound on 3/16/14 showed the previouslydescribed intrauterine gestation with fetal pole is no longerdefinitely seen. A collapsed sac however may be seen at thelower uterine segment.

Third ultrasound on 3/18/14 showed an echotextureuterus measuring 12 4.6 6.5 cm. The endometriumremained markedly thickened and heterogeneous containingmultiple cystic components. It measured up to 3.5 cm inthickness. There was increased vascularity towards the fun-dus; on the left, there was a hypoechoic structure measuring2.5 2.5 2.3 cm with mild vascularity. This was not clearlydelineated on prior imaging.There was no fluid in the cul-de-sac.

Beta-HCG Trend (mIU/mL). It was 2484 (2/26/14), 4211(3/2/14), 20571 (3/16/14), 22995 (3/18/15), and 3921 (3/21/14).

Patient underwent suction dilatation and curettage(D&C) for incomplete abortion.Moderate amount of productof conception (POC) was collected during D&C, whichpathologic examination showed to be decidua and chronicvilli (Figure 4).
