Abstract
Heterotopic pregnancy involves the coexistence of both an intrauterine and an extrauterine pregnancy occurring simultaneously. The spontaneous incidence of heterotopic pregnancy in the general population has been estimated to be 1/30,000. This report discusses the case of a 37-year-old female who presented to the emergency department with vaginal bleeding and lower abdominal pain. Upon workup, a transabdominal and transvaginal ultrasound demonstrated a heterotopic pregnancy with an estimated gestational age of seven weeks. The ultrasounds confirmed an intrauterine pregnancy with fetal cardiac activity and a fetal pole along with a right adnexal ectopic pregnancy with fetal cardiac activity and a fetal pole. Additionally, a right paratubal cyst was incidentally found. The patient subsequently underwent exploratory laparotomy with a right salpingectomy for the removal of the right tubal pregnancy and a right paratubal cyst. This case denotes the significance of a carefully performed ultrasound examination, especially in the early weeks of pregnancy. Even when a standard pregnancy is visualized with ultrasound examination, it remains imperative for the examiner to meticulously examine the adnexa and interstitial portion of the fallopian tube. A heterotopic pregnancy has the potential to be life-threatening and can often go undetected, resulting in missed diagnoses.

Abstract
Heterotopic pregnancies are a rare phenomenon defined by the simultaneous occurrence of intrauterine and extrauterine pregnancy. The incidence of heterotopic pregnancy occurring through natural fertilization is low but is increased by risk factors such as assisted reproductive techniques or pelvic inflammatory disease increase. We report the case of a 36-year-old female patient in the 6th week of pregnancy who presented to the emergency unit with severe acute lower abdominal pain. Laboratory chemistry and sonography revealed a suspected heterotopic pregnancy. The patient was admitted for observation. The sonographic reevaluation on the next day confirmed the suspicion of extrauterine gravidity with intact intrauterine gravidity with additional decreasing hemoglobin and hematoperitoneum, so that laparoscopy was indicated. Intraoperatively, the mass on the left ovary was removed without complications. The patient could be discharged quickly postoperatively after a complication-free course and gave birth to a healthy child by spontaneous partus in the 38th week of gestation. Due to their rarity, there is limited research related to heterotopic pregnancies, and most scientific articles are case studies. Diagnostically, the most important thing in clinical practice is to think about the possibility of EUG even if there is evidence of an intact IUG. Transvaginal sonography is of particular importance in diagnostics. The performance of prospective cohort studies is desirable for the evidence-based diagnosis and therapy of affected patients in the future.

Abstract
In the intricate field of obstetrics and gynecology, few scenarios present as complex a diagnostic challenge as the differentiation between heterotopic pregnancy, hyperdecidual reaction, and ectopic pregnancy. These conditions, while distinct, often blur together in clinical presentation, necessitating a nuanced understanding to achieve accurate diagnosis and timely intervention. A heterotopic pregnancy is a rare and potentially life-threatening condition in which a woman simultaneously carries two pregnancies in different locations. One pregnancy is typically located within the uterus (an intrauterine pregnancy), while the other is located outside the uterus, most commonly in one of the fallopian tubes (an ectopic pregnancy). This condition is sometimes referred to as a combined intrauterine and extrauterine pregnancy. The diagnosis of heterotopic pregnancy can be challenging because the symptoms can mimic those of a normal intrauterine pregnancy or an ectopic pregnancy. A combination of clinical symptoms, physical examination, and imaging studies, such as transvaginal ultrasound, can help in the diagnosis. After surgical or medical treatment, close monitoring and follow-up with a healthcare provider are essential. The remaining intrauterine pregnancy will need careful observation to ensure it continues to develop normally. However, in some cases of ectopic pregnancy, there will be hyperdecidual reaction within the uterus, which may sometimes create confusion with intrauterine pregnancy. Here, a case of ectopic pregnancy that was radiologically misdiagnosed as heterotopic pregnancy is presented to highlight the possibility of ectopic pregnancies being misdiagnosed as heterotopic pregnancy due to the hyperdecidual reaction. The index case underwent laparoscopic salpingectomy for tubal ectopic and dilatation and evacuation for suspected failed intrauterine pregnancy. The histopathological report of the intrauterine products of conception confirmed it to be decidua without any trophoblastic tissue.

Abstract
A heterotopic pregnancy is a rare and serious pathological pregnancy. In this paper, we report a rare case of heterotopic pregnancy and perform a literature review. A 30-year-old patient with a history of left adnexectomy presented with persistent lower abdominal pain and hemorrhagic shock after single embryo transfer. Emergency laparoscopic exploration revealed a ruptured mass in the right isthmus of the fallopian tube, for which right salpingectomy was performed. After anti-inflammatory treatment and fetal preservation, the intrauterine pregnancy progressed smoothly, and a healthy baby was delivered at 39 weeks gestation. In this case, the patient's heterotopic pregnancy was possibly due to a natural pregnancy caused by sexual intercourse during treatment, so we recommend that sexual intercourse be avoided during transfer cycles.

J Gynecol Obstet Hum Reprod 2024; 53:102701.

Abstract
Heterotopic pregnancy is an extremely rare condition in which an intrauterine and an extrauterine pregnancy co-exist. In spontaneous conceptions, heterotopic pregnancy occurs in only 1/30 000 pregnancies. The treatment of heterotopic pregnancy must be as minimally invasive as possible to preserve the development of the intrauterine pregnancy. Superfetation, defined as the coexistence of 2 or more foetuses of different gestational ages, remains particularly exceptional and poorly explained (second ovulation? embryonic diapause?). Here, we present an extremely rare case of a spontaneous heterotopic evolutive pregnancy with superfetation, consisting of an embryo in the pouch of Douglas estimated at 8 + 1 weeks of gestation (WG) and a progressive intrauterine pregnancy estimated at 5 + 4 WG. We treated the extrauterine pregnancy with an intra-cardiac injection of potassium chloride echo-guided via the vaginal route, and the patient then underwent exploratory laparoscopy 9 days later and lavage and aspiration of the abdominal heterotopic pregnancy due to pain and biological inflammatory syndrome probably caused by pelvic mass syndrome and peritoneal irritation from the foetal necrosis. She has not yet given birth and is currently at 36 WG.

Abstract
Heterotopic pregnancy (HP) is a rare phenomenon. Despite its rarity, there has been a notable increase in its incidence in recent decades due to the greater use of in vitro fertilization (IVF). However, information about the relation between ovarian stimulation and HP is scarce. We report a case of HP after ovarian stimulation using clomiphene citrate. A 26-year-old pregnant woman presented to the emergency department with mild vaginal bleeding, and abdominal pain. She had a history of pelvic inflammatory disease (PID) and left salpingectomy due to a previous ectopic pregnancy. She had undergone ovarian stimulation with clomiphene citrate three months earlier. Transvaginal ultrasound revealed an eight-week-old ruptured tubal pregnancy with an intrauterine ten-week-old gestational sac confirming superfetation HP. An urgent laparoscopic right salpingectomy was performed and the extrauterine pregnancy was successfully removed with the preservation of the intrauterine embryo. The course of the intrauterine pregnancy was uneventful and the patient gave birth to a healthy boy via cesarean section. Women receiving ovarian stimulation are at an increased risk of developing HP especially when they also have other predisposing factors for HP. Thus, close monitoring using transvaginal ultrasound with extra attention to the adnexa is required for a timely diagnosis and management of HP.

Abstract
OBJECTIVE To compare the treatment effects of laparoscopy versus laparotomy on heterotopic pregnancy (HP) after in vitro fertilization-embryo transfer (IVF-ET). METHODS The retrospective case-control study enrolled 109 patients diagnosed with HP after IVF-ET treatment in our hospital from January 2009 to March 2020. All patients received surgical treatment by either laparoscopy or laparotomy. Data for general characteristics, diagnostic features, surgical parameters, as well as perinatal and neonatal outcomes were collected. RESULTS Sixty-two patients received laparoscopy and 47 received laparotomy. Significantly lower percentage of large hemoperitoneum (P = 0.001), shorter surgery duration (P < 0.001), less intraoperative blood loss (P = 0.001), higher rates of general anesthesia (P < 0.001), and lower cesarean section rates for singletons (P = 0.003) were found in the laparoscopy group. The perinatal and neonatal outcomes were comparable between the two groups. When interstitial pregnancy was considered alone, the surgical blood loss was significantly reduced in the laparoscopy group (P = 0.021), but there was no significant difference in hemoperitoneum, surgery duration, or perinatal and neonatal outcomes in singletons. CONCLUSION Both laparoscopy and laparotomy are effective surgical treatments for HP after IVF-ET. Laparoscopy is minimally invasive but laparotomy can be an alternative in emergency situations.

Abstract
KEY MESSAGE Both expectant and interventional managements are acceptable in selected cases, when heterotopic pregnancy is diagnosed, with high ongoing intra-uterine pregnancy rate and term deliveries. PURPOSE Heterotopic pregnancy, though relatively rare, is potentially a life-threatening condition. The aim of the study is to compare expectant versus interventional management of heterotopic pregnancies. METHODS This is a retrospective cohort study including all women diagnosed with heterotopic pregnancy on ultrasound from March 2011 to December 2020 in a single medical center. Expectant and interventional management outcomes were compared. Primary outcome was defined as live birth. RESULTS Forty-one women were diagnosed with heterotopic pregnancy during the study period. Management was expectant in 10 (24.4%) and interventional in 31 (75.6%) of the women. Expectant management was considered when the patient was stable, and the attending physician decided that the ectopic pregnancy did not continue to develop. Interventions included laparoscopic salpingectomy (n = 26), laparoscopic cornual resection (n = 2), laparotomic cornual resection (n = 1) and gestational sac aspiration (n = 2). The intra-uterine pregnancy continued to develop in 6 (60.0%) and 22 (81.5%) of the women in the expectant and interventional groups, respectively (p = 0.52). All women managed expectantly reached term delivery, as opposed to 17/22 (77.3%) in the intervention management group (p = 0.60). Multivariate analysis found serum β-hCG level as the only independent parameter associated with ongoing pregnancy rate (B = 0.001, p = 0.04). CONCLUSIONS Both expectant and interventional management were found to be acceptable when heterotopic pregnancy was diagnosed, with high ongoing intra-uterine pregnancy rate and term deliveries.

Utalo T, Getu J. A unique case of coexisting intrauterine and abdominal pregnancy which progress to term with a positive birth outcome. BMC Pregnancy Childbirth 2022; 22:243.

Abstract
BACKGROUND The term heterotopic pregnancy is defined as a uterine pregnancy coexisting with a second pregnancy in an extrauterine location. Spontaneous, full-term heterotopic pregnancy with alive birth is very rare. The diagnosis and management of such exceptionally unique case is difficult. When the patient presented with an advanced labor with no antenatal care follow up and with no risk factors is even more challenging for poorly equipped facilities like ours. CASE PRESENTATION A 25 years old gravida 3, para 2 (both are alive) mother presented to the labor and delivery ward of Bele Primary Hospital, Southern Ethiopia with the complaint of pushing down pain of 18 h duration. Immediately after arrival, she gave birth to a 3300gm female neonate spontaneously. After delivery, an abdominal mass was recognized and manual exploration of the uterus was done to look for the presence of after coming second twin but the uterus was empty. On ultrasound examination, there was an alive fetus in transverse lie outside the uterus. With the impression of 2nd twin in a separate horn of bicornuate uterus and to rule out abdominal pregnancy, laparotomy was done. On laparotomy, there was abdominal pregnancy in the Pouch of Douglas with an intact amniotic sac. The sac was attached with the left broad ligament, left ovary, small bowel mesentery, and posterior wall of the uterus. The sac opened, a 1600gm alive female neonate with features of fetal growth restriction and left club foot was delivered. The placenta was detached spontaneously and removed without any complication. CONCLUSIONS The coexistence of spontaneous full-term intrauterine with advanced abdominal ectopic pregnancy is one of the rarest forms of heterotopic pregnancy. Every health professional should bear in mind that intrauterine and extrauterine pregnancy may happen simultaneously and it can progress to term without any symptoms. Ultrasound is the diagnostic method of choice but the existence of an intra-uterine pregnancy cannot rule out ectopic pregnancy. The life-threatening complication of abdominal ectopic pregnancy is bleeding from the detached placental site. Therefore, the decision to remove the placenta should be individualized.

Abstract
OBJECTIVE To investigate whether there is a difference in the ectopic/heterotopic pregnancy rate of blastocyst-stage frozen-thawed embryo transfers (FETs) compared with that of cleavage-stage FETs. DESIGN A retrospective cohort study. SETTING Not applicable. PATIENTS Women undergoing autologous FETs at either the blastocyst stage (n = 118,572) or the cleavage stage (n = 117,619), as reported to the Society for Assisted Reproductive Technology from 2004 to 2013. INTERVENTIONS None. MAIN OUTCOME MEASURES Pregnancy outcomes, specifically ectopic pregnancy rates and heterotopic pregnancy rates. RESULTS Among those who became pregnant, there was a significantly lower incidence of ectopic/heterotopic pregnancies in blastocyst-stage FETs versus that in cleavage-stage FETs (0.8% vs. 1.1%). The differences in ectopic/heterotopic pregnancy rates remained statistically significant after controlling for confounders such as tubal factor infertility and number of embryos transferred. CONCLUSIONS Blastocyst-stage FET was associated with a lower ectopic/heterotopic pregnancy rate compared with cleavage-stage FET.

Abstract
We report the case of a 36-year-old woman with spontaneously conceived heterotopic pregnancy with abdominal pregnancy. She visited the hospital at 5 weeks and 4 days of gestation and transvaginal ultrasonography revealed a normal intrauterine pregnancy. Two days later, she was urgently transported to the hospital due to extreme abdominal pain. Emergent laparotomy was performed to investigate the cause of massive intraperitoneal bleeding, which was confirmed to have been due to an abdominal pregnancy that implanted on the vesicouterine pouch. The hematic mass, including chorionic villi, was successfully removed from the peritoneum. The subsequent course of the intrauterine pregnancy was uneventful and a healthy baby was born at term. To the best of our knowledge, this is an extremely rare case report of a spontaneously conceived heterotopic abdominal pregnancy, in which the intrauterine pregnancy showed a successful outcome despite the collapse of the abdominal pregnancy at a very early stage.
