Ultrasound manifestations and clinical analysis of 50 cases of heterotopic pregnancy

OBJECTIVE

To investigate the value of ultrasonography in the diagnosis of heterotopic pregnancy and the follow-up.

METHODS

A retrospective analysis of 50 cases of clinically diagnosed heterotopic pregnancy in our hospital was performed, the clinical characteristics and ultrasonographic manifestations of the patients were summarized, the reasons for initial ultrasound missed diagnosis and misdiagnosis were analyzed, and the pregnancy outcomes were followed up.

RESULTS

Among the 50 cases, the initial ultrasound diagnoses of intrauterine pregnancy were all gestational sac type, 32 cases of ectopic pregnancy were located in the fallopian tube, and 10 cases were located in the uterine horn, 1 case at cervix, and 1 case at caesarean section scar. Forty-one cases were consistent with surgery and/or pathology, representing initial ultrasound diagnosis coincidence rate of about 82%. Six cases were missed in the initial ultrasound examination (12%), and three cases were misdiagnosed (6%). The maximum diameter of the intrauterine gestational sac was 9-48 mm, the average was about 24.90 ± 9.56 mm, the maximum diameter of the ectopic pregnancy gestational sac or mass was 11-63 mm, and the average was about 31.45 ± 13.82 mm (p < 0.05). Intrauterine pregnancy outcomes were followed up, 45 patients with complete data and 5 patients were lost to follow-up. The follow-up rate was about 90%.

CONCLUSION

Combining the patient's medical history and clinical characteristics can reduce missed diagnosis and misdiagnosis of heterotopic pregnancy. Ultrasonography has important value in the assessment of intrauterine pregnancy growth and development, and the integrity of maternal uterus.

A Spontaneous Tubal Heterotopic Triplet Pregnancy Resulting in Viable Twin Deliveries

There are limited U.S. reports of spontaneous triplet heterotopic pregnancies discussing both maternal and fetal outcomes. A 34-year-old patient at 7 weeks of gestation presented to the emergency department with abdominal pain. She was diagnosed with a spontaneous heterotopic triplet pregnancy, consisting of a twin monochorionic-diamniotic intrauterine gestation and a ruptured left ectopic pregnancy. She underwent a laparoscopic unilateral salpingectomy. Her antepartum course was complicated by gestational diabetes mellitus and fetal growth restriction. Delivery of liveborn twins was via a cesarean delivery at 32 weeks. Timely intervention and management of a ruptured spontaneous triplet heterotopic pregnancy can result in a viable twin delivery with overall favorable maternal and newborn outcomes, although long-term implications due to prematurity and other twin sequelae exist.

Spontaneous Heterotopic Cesarean Scar Triplet Gestation Following Uterine Ablation

Heterotopic triplet pregnancy, cesarean scar ectopic pregnancy, and pregnancy following uterine ablation are all rare events that confer significant morbidity including spontaneous abortion, intrauterine fetal demise, preterm labor, abnormal placentation, and uterine rupture. A woman in her 30s, G6P4014, with a history of uterine ablation presented with delayed menses and vaginal spotting with imaging showing two intrauterine pregnancies (one with cardiac activity) and one live pregnancy at the cesarean scar. The patient was extensively counseled on risk to her and to the pregnancies; treatment options were discussed including expectant management and termination of pregnancy. The patient underwent an uncomplicated dilation and curettage with bilateral salpingectomy and was discharged home the day of the procedure in stable condition. This case highlights the potential compound effect of comorbid conditions that can pose difficulty in counseling and management. Key Points Patients undergoing endometrial ablation should be carefully selected and counseled extensively on highly effective contraception.Suspected cesarean scar pregnancies should be carefully evaluated early in gestation. Management should include thorough counseling and may be indivisualized.Many conditions pose a significant threat to maternal health and warrant a discussion of termination, which should be widely availaible and safe for all who need and/or desire it.

Forensic Analysis of Eighteen Tubal Pregnancy-Related Medical Damage

OBJECTIVES

To analyze the cases of medical damage after misdiagnosis of tubal pregnancy, to explore the causes of medical damage, the causal relationship between medical malpractice and the damage consequences, as well as the causative potency, in order to provide evaluation ideas for forensic identification of such cases.

METHODS

Eighteen cases of forensic identification of tubal pregnancy related medical damage were collected and retrospectively analyzed from the aspects of age, maternity history, fertility requirements, risk factors, diagnosis and treatment, medical malpractice, damage consequences, and causative potency.

RESULTS

All 18 cases were tubal pregnancy, of which 17 cases had medical malpractice, resulting in 14 cases of affected tubal resection, 2 cases of hemorrhagic shock death, 1 case of intrauterine fetal death and affected tubal resection. The other case had the consequence of affected tubal resection, but there was no malpractice in the treatment.

CONCLUSIONS

Correct diagnosis is helpful to make appropriate treatment plan, prevent disease progression and reduce serious adverse consequences and the occurrence of medical disputes. Scientific and reasonable analysis of the causal relationship between medical malpractice and damage consequences and the causative potency is of great significance to the successful settlement of medical disputes.

The risk factors for miscarriage of viable intrauterine pregnancies in patients with heterotopic pregnancy after surgical intervention

To summarize the clinical characteristics and explore the risk factors for miscarriage of a viable intrauterine pregnancy following surgical intervention in patients with heterotopic pregnancy (HP). A total of 106 women diagnosed with HP that underwent surgical intervention in the Women's Hospital School of Medicine Zhejiang University between January 2014 and December 2021 were included in this retrospective study. They were divided into a miscarriage group (n = 13) and an ongoing pregnancy group (n = 93) according to the outcomes of the HP within 2 weeks after surgery. Data regarding clinical characteristics, surgical conditions, postoperative recovery, and complications were collected and compared between the groups. Logistic multivariate analysis was performed to explore the risk factors for miscarriage in patients with HP within 2 weeks of surgical intervention. Among the 106 women with HP, 80 had tubal HP, 8 had cornual HP, and 18 had interstitial HP. Eighty-seven (82.1%) patients developed clinical symptoms that manifested primarily as abnormal vaginal bleeding and/or abdominal pain, whereas 19 (17.9%) patients had no clinical symptoms. The mean gestational age on the day of surgery was 7.2 weeks (inter-quartile range, 6.4-8.3). The miscarriage rate within 2 weeks of surgical intervention was 12.3% in patients with HP. Compared to the ongoing pregnancy group, the miscarriage group had a higher body mass index, earlier gestational age at treatment, and higher volume of hemoperitoneum (P < .05 for all). Logistic multivariate analysis indicated that the women with a hemoperitoneum volume > 200 mL had significantly higher risk of miscarriage after adjusting covariates [OR (odds ratio) = 5.285, 95% CI (confidence interval) (1.152-24.238), P < .05]. Hemoperitoneum volume was independently associated with miscarriage of viable intrauterine pregnancies in patients with HP within 2 weeks of surgical intervention.

Study on diagnosis and management strategies on heterotopic pregnancy: a retrospective study

Heterotopic pregnancy (HP) is a rare but potentially life-threatening event with a high risk of maternal death, which also jeopardise the coexisting intrauterine pregnancy (IUP), thus an early accurate diagnosis and prompt treatment can decrease adverse complications. We aimed to explore the early predictors for pregnancy outcomes of HP. We reviewed patients with HP following assisted reproductive technology in our institution between January 2013 and December 2020. The relationships between pregnancy outcomes and clinical features were analysed by logistic regression. We found that 29 patients (72.5%) of HP were accurately diagnosed by transvaginal ultrasonography (TVS). Eighteen patients in the surgery group had live births, three of whom delivered preterm. Additionally, the miscarriage rate was lower for patients with IUP cardiac activity than those without (16.7% vs. 90.0%, p < .001). Further by logistic regression analysis, an IUP with cardiac activity at HP diagnosis was identified as favourable independent predictor of live birth (p < .001). Therefore, early diagnosis and prompt surgical intervention are recommended to prevent the development of HP.Impact of statementWhat is already known on this subject? Heterotopic pregnancy (HP) has long been thought to be a rare but potentially life-threatening event with a high risk of complications. The early diagnosis of HP is challenging due to the co-existence of a viable intrauterine pregnancy (IUP) and the absence of typical clinical symptoms.What do the results of this study add? This stduy showed that symptoms combined with routine transvaginal ultrasonography (TVS) scans reduce the rates of misdiagnosis of HP and prompt surgical intervention after diagnosis may minimise the incidence of miscarriage of the IUP.What are the implications of these findings for clinical practice and/or further research? An IUP with cardiac activity at HP diagnosis is a predictor of a favourable prognosis of HP, and laparoscopy under general anaesthesia is effective and safe during the first trimester of pregnancy. Awareness, assessment and early interventions in view of symptoms combined with routine TVS is recommended to reduce the risk of miscarriage and ensure a favourable live birth rate.

Treatment effects of laparoscopy versus laparotomy on heterotopic pregnancy after in vitro fertilization and embryo transfer

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.

Diagnosing Emergent Heterotopic Pregnancy via Point-of-Care Ultrasound: A Case Report

Patients undergoing assisted reproductive treatments are at a much higher risk for developing heterotopic pregnancy, a rare complication marked by concurrent intrauterine and ectopic pregnancies. Ruptured ectopic pregnancies are one of the leading causes of pregnancy-related mortality. We report the case of a 31-year-old woman undergoing ovulation induction that presented to the emergency department (ED) with worsening abdominal pain. Point-of-care ultrasound (POCUS) performed in the ED identified a heterotopic pregnancy in which the ectopic gestational sac had ruptured. The patient was immediately taken to the operating room for surgical management without obtaining a formal radiology-performed ultrasound. Nonspecific abdominal pain is one of the most common complaints for patients presenting to the ED. The usage of POCUS allows for rapid visualization of the abdominal cavity to diagnose the underlying cause of a patient's abdominal pain. This case demonstrates that complex etiologies can be reliably visualized and diagnosed without needing to wait for a formal radiology study.

Laparoscopic management of a second trimester ruptured spontaneous heterotopic tubal pregnancy mimicking ovarian tumour, a case report

BACKGROUND

Laparoscopic surgery in the second trimester of pregnancy is a high risk and demanding operation. Especially when dealing with adnexal pathology, the surgeon should balance between the effort to establish adequate visualisation of the operating field with minimal uterine manipulation and use of energy application to avoid any potential adverse effects on the intrauterine pregnancy.

OBJECTIVE

The video shows laparoscopic surgery performed in the second trimester of pregnancy and highlights modifications to technique to ensure safety. Materials and Methods: We present a case report of spontaneous heterotopic tubal pregnancy that mimicked an ovarian tumour and was managed surgically with a laparoscopy in the second trimester. During surgery, a previously ruptured left tubal pregnancy (? ectopic) was the cause for a concealed hematoma in the pouch of Douglas, misdiagnosed as ovarian tumour. This is one of the few cases of heterotopic pregnancy treated by laparoscopy in the second trimester of pregnancy.

RESULTS

The patient was discharged the day 2 post-operatively, the intrauterine pregnancy progressed, and the patient delivered with a planned caesarean section on the 38th week.

CONCLUSIONS

Laparoscopic surgery, with adjustments, is a safe and effective method to manage adnexal pathology during a second trimester pregnancy.

Management of heterotopic pregnancy: clinical analysis of sixty-five cases from a single institution

Objective

This retrospective study aims to analyze the influence of different treatment modalities on viable intrauterine pregnancy and to summarize the clinical features of heterotopic pregnancy (HP) patients.

Material and methods

All patients diagnosed with HP between January 2012 and December 2022 in Tianjin Central Obstetrics and Gynecology Hospital were reviewed retrospectively.

Results

This study diagnosed 65 patients using transvaginal ultrasound (TVS), including two cases of natural pregnancy, seven cases of ovulation induction pregnancy, and 56 cases after in vitro fertilization and embryo transfer (IVF-ET). The gestational age was 50.2 ± 13.0 days at the time of diagnosis. The most frequent manifestations were abdominal pain (61.5%) and vaginal bleeding (55.4%), while 11 patients (16.9%) had no symptoms before the diagnosis. The primary treatment was expectant and surgical management, including laparotomy and laparoscopic surgery. In the expectant management group, four patients were transferred to surgery due to rupture of ectopic pregnancy or ectopic pregnancy mass gradually enlarged. In the surgical management group, 53 patients underwent laparoscopic surgery, and six underwent laparotomy. The laparoscopic group's mean operation time was 51.3 ± 14.2 min (range: 15-140 min), and the median intraoperative blood loss was 20 mL (range 5-200 mL). In contrast, the laparotomy group's mean operation time was 80.0 ± 25.3 min (range 50-120 min), and the median intraoperative blood loss was 22.5 mL (range 20-50 mL). Four patients had postoperative abortions. Sixty-one newborns had no birth abnormalities, and no developmental malformations were discovered after a median follow-up of 32 months.

Conclusion

Expectant treatment has a high failure rate in HP, and laparoscopic surgery is a safe and effective treatment for removing ectopic pregnancy without increasing the risk of abortion or newborn birth defects.

Successful Management of Triplet Heterotopic Pregnancy (Interstitial) With an Intrauterine Monochorionic Diamniotic Twin Pregnancy Through Laparoscopy: A Case Report

The simultaneous occurrence of intrauterine (IU) and extrauterine pregnancies is known as heterotopic pregnancy, an uncommon clinical condition that is challenging to manage. It can be a potentially fatal illness if it remains unnoticed. This is a case report of a woman who had heterotopic triplets after transferring two embryos produced through in vitro fertilization. An ultrasound scan diagnosed live interstitial heterotopic pregnancy and an intrauterine monochorionic twin pregnancy. Laparoscopic resection of interstitial heterotopic pregnancy was done. The monochorionic twin pregnancy was closely monitored by serial ultrasound, and at 36 weeks of gestation, two healthy twins were delivered by cesarean section. The fetal growth parameters were monitored, and a dopplers study was conducted to assess fetal blood flow. Even in heterotopic pregnancy, timely diagnosis and therapeutic intervention can preserve IU pregnancy with a successful outcome. Early meticulous monitoring and early detection can lead to a favorable outcome. Even in heterotropic pregnancy, a meticulous evaluation can lead to favorable outcomes by conserving IU pregnancy, and timely intervention can prevent maternal motility.

Atypical presentations of ectopic pregnancies in a rural tertiary care hospital-A case series

In spite of advances in medical sciences, diagnosis of ectopic pregnancy eludes the clinician. In this case series, we describe three variants of life-threatening pregnancies. The successful management of these cases hinged on a strong index of suspicion and early detection. Heterotopic pregnancy is the occurrence of two pregnancies in different implantation sites at the same time, which is uncommon. Heterotopic pregnancy is uncommon in natural conception, despite its prevalence in assisted reproductive technologies. A strong index of suspicion and timely laparotomy was life-saving for the woman. Caesarean scar pregnancy is a form of ectopic pregnancy in which an aberrant pregnancy is implanted at the hysterotomy site of a prior caesarean procedure. Unexplained excessive bleeding at the time of medical termination of pregnancy prompted us to explore and make a timely diagnosis of caesarean scar pregnancy. Finally, tubal choriocarcinoma is a very aggressive, extremely rare trophoblastic tumour that can be either gestational or non-gestational. High serum beta HCG raised the suspicion and timely laparotomy confirmed the diagnosis. An alert clinician who takes timely decisions can avert life-threatening complications in these pregnancies.

Intrauterine hydatidiform mole complicated with tubal ectopic pregnancy: a case report

Heterotopic pregnancies are rare pathological pregnancy disorders in clinical practice. However, the number of cases has increased with the widespread use of ovulation induction drugs in recent years. The clinical manifestations of heterotrophic pregnancies are diverse and easy to missed or misdiagnosed. A 33-year-old married Gravida1 Para 0 + 0 patient was admitted on December 8, 2020 with intermittent abdominal pain 18 days after uterine curettage for complete hydatidiform mole of 8 weeks gestation. She had ovulation-promoting drugs prior to the index pregnancy. Hysteroscopic-directed endometrial biopsy and laparoscopic left tubal surgery were offered to her; and she is being followed up with serial pelvic ultrasounds and β-Human Chorionic Gonadotrophin (βHCG) assays. This case study presents a case of intrauterine hydatidiform mole complicated with tubal pregnancy to highlight the problems associated with its diagnosis and treatment.

Ovarian Pregnancy: 2 Case Reports and a Systematic Review

Ovarian pregnancy is a rare but well-known pathology. However, pathophysiology, diagnosis and treatment are not established. Therefore, all case reports on ovarian pregnancy published in PubMed from November 2011 till November 2022 were reviewed and two case reports were added. In these 84 case reports, 8% of ovarian pregnancies occurred in women without or with blocked oviducts and 23% were localised on the other side than the corpus luteum. Since symptoms are not specific, ovarian pregnancy has to be suspected in all women with abdominal bleeding. Surgical excision is the preferred treatment. However, since an associated intra-uterine pregnancy cannot be excluded, care should be taken not to interrupt this intra-uterine pregnancy with the uterine cannula or by damaging the corpus luteum. In conclusion, in women with abdominal bleeding, an ovarian pregnancy cannot be excluded, even in women with a negative pregnancy test or an empty uterus on transvaginal ultrasonography. Therefore, a laparoscopy is indicated but the surgeon should realise that an associated intra-uterine pregnancy also cannot be excluded and that therefore care should be taken not to interrupt this intra-uterine pregnancy by the uterine cannula or by damaging the corpus luteum.

Heterotopic Pregnancy with Ipsilateral Adnexal Cyst Causing a Diagnostic Dilemma: A Case Report

Background

Heterotopic pregnancy is the coexistence of intrauterine and extrauterine (ectopic) pregnancies. This is a relatively rare phenomenon with an incidence of 1 in 30,000 in spontaneously conceived pregnancies and 1 in 100 pregnancies achieved through assisted reproduction. Due to its relative rarity, diagnosis can be challenging. The presence of adnexal cystic masses complicating pregnancies can obscure the examination of the pelvis to rule in/out heterotopic pregnancy further adding to the complexity of the diagnosis.

Case Presentation

In this study, we present a 26-year-old primigravid, ethnic Tigrayan lady from the Tigray region of Ethiopia. She presented to our hospital with the complaint of progressively worsening abdominal pain of three days duration. She also had a subjective period of amenorrhea of 2 months duration. Pregnancy test was positive a few days prior to her current presentation. She reported that she had a history of treatment for pelvic inflammatory disease three months prior to her current conception. At presentation to our hospital, she was acutely ill-looking in pain, tachycardic, and hypotensive. Pelvic ultrasound showed an adnexal mass, hemoperitoneum, and an intrauterine pregnancy at 7 weeks + 5 days gestation. With the impression of ruptured ovarian cyst to rule out heterotopic pregnancy emergency, an explorative laparotomy was done which was pertinent for significant hemoperitoneum, ruptured left tubal ectopic pregnancy, and intact left ovarian cyst.

Conclusion

Physicians should consider a broad range of differential diagnosis in pregnant mothers who present with acute abdominal pain. Moreover, in the presence of an adnexal mass and hemoperitoneum, there is a need to maintain a low threshold for rare but life-threatening complications such as heterotopic pregnancy. The presence of an intrauterine gestation does not rule out extrauterine gestation. Thus, the presence of a viable intrauterine gestation should not stop physicians from carefully examining patients for the coexistence of an ectopic pregnancy.

Bilateral tubal ectopic pregnancy after spontaneous conception

OBJECTIVE

Presentation of a case report of a rare case of bilateral tubal pregnancy in a female patient after spontaneous conception.

OBSERVATION

We present a case of a 26-year-old female patient first hospitalized in the Gynecology Obstetrics Clinic of the Pilsen University Hospital, where a laparoscopy was indicated for suspicion of ectopic tubal pregnancy during which a left-sided salpingectomy was performed for a macroscopically clear finding of a tubal pregnancy on the left side, this finding was also confirmed histologically. Subsequently, the patient was discharged to home care. During a follow-up examination by a district gynaecologist, the patient complained of a recurrence of pain in the lower abdomen, on collection of hCG (human chorionic gonadotropin) its increase was detected and the patient was sent for a control gynaecological examination to Mulacova Hospital in Pilsen. On the examination in the outpatient clinic, she reported significant lower abdominal pain and collapsed during transvaginal ultrasound and was hospitalized. Subsequently, diagnostic laparoscopy was indicated during hospitalization, during which tubal pregnancy on the right and hemoperitoneum were macroscopically evident. A right-sided salpingectomy was performed for this finding with subsequent hCG drop, resolution of the discomfort and histological confirmation of tubal pregnancy on the right.

CONCLUSION

The incidence of such cases without prior ovulation stimulation is 1 out of 200,000 pregnancies and an estimated 1 out of 725 to 1 out of 1,580 ectopic pregnancies. Even so, bilateral tubal or heterotopic ectopic pregnancy should be considered in the differential diagnosis, as both conditions can be immediately life-threatening.

Management of a uterine serosal heterotopic pregnancy after in vitro fertilization in a woman with bilateral salpingectomy: A case report and literature review

RATIONALE

Heterotopic pregnancy (HP) is defined as the simultaneous presence of intrauterine pregnancy and ectopic pregnancy (EP). HP after bilateral salpingectomy is extremely rare and may lead to serious complications if it is misdiagnosed and untreated timely. Here, we presented the first reported case of uterine serosal HP in a woman after assisted reproductive technology with bilateral salpingectomy because of bilateral tubal ectopic pregnancy.

PATIENT CONCERNS

A 27-years-old pregnant woman after in vitro fertilization with bilateral salpingectomy complained of a sudden onset of unprovoked abdominal pain, which was persistent and dull. She denied vaginal bleeding.

DIAGNOSES

Serum beta-human chorionic gonadotropin levels are difficult to predict HP. Transvaginal ultrasonography demonstrated 1 gestational sac in the uterine cavity and 1 thick-walled cystic mass over the upper of the uterus, with a large amount of fluid in the Pouch of Douglas. Emergency laparotomy revealed a uterine serosal pregnancy combined with intrauterine pregnancy.

INTERVENTIONS

This patient was successfully managed via emergency laparotomy to remove residual tissue and repair the rupture of the uterine serosal pregnancy.

OUTCOMES

At postoperative 4 days, repeat transvaginal ultrosonography presented 1 intrauterine gestational sac with a visible fetal bud and cardiac tube pulsation. Now the patient recover well and is in an ongoing pregnancy.

LESSONS

It is noteworthy that HP/ectopic pregnancy is still not prevented after bilateral salpingectomy. In cases of multiple embryo transfer, even if intrauterine pregnancy has been established, it is important to rule out HP/ectopic pregnancy in time. Early diagnosis and early management can significantly improve clinical outcomes.

Treatment of heterotopic cervical pregnancy by ultrasound-guided hysteroscopy: A case report and literature review

BACKGROUND

Heterotopic cervical pregnancy is a rare event of ectopic pregnancy with an incidence rate of < 1%. Herein, we report a rare case of successful treatment of heterotopic pregnancy following an in vitro fertilization-embryo transfer using ultrasound-guided hysteroscopy. In order to choose the best treatment option, we reviewed the clinical treatments and discussion of heterotopic cervical pregnancy over the last 15 years.

METHODS

The heterotopic pregnancy was terminated using ultrasound-guided hysteroscopy; however, the intrauterine pregnancy was maintained. We searched for the keywords "cervical pregnancy combined with intrauterine pregnancy," "compound pregnancy," "assisted reproductive technology," "cervical pregnancy," and "ectopic pregnancy" on PubMed to include articles published in the last 15 years.

RESULTS

The patient underwent an emergency cervical cerclage at 22 weeks' gestation for cervical insufficiency and delivered a healthy newborn at 38 weeks' gestation by transvaginal compliance. Twenty-one relevant case reports were selected. After analysis and discussion, we found that assisted reproductive technology is more likely to lead to heterotopic pregnancy than unassisted reproduction. Most women requesting the preservation of intrauterine embryos opted for surgical termination of cervical pregnancy and achieved the ideal outcomes.

CONCLUSION

More attention should be paid to the diagnosis and treatment of heterotopic pregnancies to obtain the most optimal pregnancy outcome and long-term prognosis. Hysteroscopic surgery is a completely feasible cervical pregnancy treatment option with less postoperative impact on the mother and the intrauterine fetus.

Comparison of laparoscopic and open approach in the treatment of heterotopic pregnancy following embryo transfer

PURPOSE

Heterotopic pregnancy (HP) is a rare disease with the coexistence of an intrauterine and ectopic embryos. There is no consensus on the optimal treatment of HP at present. This research aimed to compare the perioperative and pregnancy outcomes of laparoscopic (LA) and open approach (OA) in patients with HP after embryo transfer.

METHODS

Women with HP receiving surgical treatment (LA or OA) were retrospectively recruited in this study between October 2006 and December 2020. The demographic, perioperative and obstetric data were collected and compared between LA and OA group.

RESULTS

Totally, 86 patients were included in this study. Among these patients, 62 underwent LA and 24 underwent OA. There was an increase in the adoption of LA between the 2006-2012 period and the 2013-2020 period [25% (6/24) vs. 90% (56/62), p < 0.001]. Compared with OA, patients treated by LA had much less blood loss [20 (10-50) vs. 30 (20-50) ml, p = 0.036] and fewer days of hospital stay [5.0 (4.0-7.3) vs. 9.5 (7-15.3) days, p < 0.001], but a relatively higher cost (15,580 ± 3196¥ vs. 11,717 ± 3820¥, p < 0.001). During the laparoscopic procedure, no one needed to be converted to open surgery. However, the rates of first trimester miscarriage, preterm, cesarean section, birth weight, 1- and 5-min Apgar were similar between LA and OA group (all p > 0.05).

CONCLUSIONS

Compared with open approach, laparoscopy was shown to provide a comparable pregnancy outcomes and a better performance on perioperative outcomes in the treatment of HP patients with embryo transfer.

Heterotopic cervical pregnancy: Case report and literature review

Cervical pregnancy (CP) is a rare form of ectopic pregnancy (EP) in which the embryo implants and grows inside the endocervical canal. Heterotopic cervical pregnancy is an even rare form of EP, in which at least two embryos are simultaneously implanted in different sites and only one in the uterine cavity. Although many treatment approaches are available, the ideal management remains unclear. Here, we describe two cases of CP caused by assisted reproductive technologies (ART). One case underwent fertilization with intracytoplasmic sperm injection (ICSI) for male factor infertility, and the other was frozen–thawed embryo transfer (FET) following conventional in vitro fertilization (IVF). Both cases were successfully treated with ultrasound‐guided cervical pregnancy aspiration, and intrauterine pregnancies were effectively protected. To the best of our knowledge, these two were rare case reports use aspiration without additional methods and intrauterine pregnancy achieved live birth.

The incidence of ectopic/heterotopic pregnancies after blastocyst-stage frozen-thawed embryo transfers compared with that after cleavage-stage: a Society for Assisted Reproductive Technologies Clinical Outcomes Reporting System study

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.

Patient(s)

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.

Intervention(s)

None.

Main Outcome Measure(s)

Pregnancy outcomes, specifically ectopic pregnancy rates and heterotopic pregnancy rates.

Result(s)

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.

Conclusion(s)

Blastocyst-stage FET was associated with a lower ectopic/heterotopic pregnancy rate compared with cleavage-stage FET.

First trimester heterotopic pregnancy with shock treated laparoscopically, followed by uneventful term pregnancy and normal birth

Heterotopic pregnancy (HP), a coexistence of intrauterine and ectopic pregnancies, is extremely rare. Although there have been many reports of maternal outcomes in pregnant women with HP, they have not described fetal neurodevelopmental outcomes and survival. A 30-year-old Japanese woman in early gestation who had undergone two previous cesarean deliveries was transferred to our hospital with vital signs of shock. HP was confirmed by ultrasonography and laparoscopic surgery, and right salpingectomy was performed. At term, a 2,875 g neonate was delivered via cesarean section without any complications.

Cervical Twin Heterotopic Pregnancy: Overview of Ectopic Pregnancies and Scanning Detection Algorithm

Background: Ectopic pregnancy is the leading cause of gestation-related deaths during the first trimester. Cervical twin heterotopic pregnancies, when ectopic, constitute a small and rare part of gynecological surgery. Case Presentation: A 30-year-old pregnant woman (gravida 3, para 2) presented with mild pain in the lower abdomen and traces of bleeding per vaginum for three days. Transvaginal ultrasonography revealed a balloon-shaped cervical canal with a visible gestational sac measuring 3.5 × 3.9 cm. A second gestational sac was seen in the uterine cavity. The measurements of the gestational sacs corresponded to 7 + 4 weeks' pregnancy. A decision for medical abortion with mifepristone and misoprostol was made. However, due to an incomplete abortion and continuous bleeding, a curettage was performed. Conclusions: Spontaneous heterotopic pregnancy with the ectopic pregnancy located in the cervix is an extremely rare clinical condition requiring urgent treatment in order to reduce maternal mortality and morbidity and preserve fertility.

Spontaneously conceived heterotopic pregnancy with abdominal pregnancy implanted on the vesicouterine pouch: A case report and literature review

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.

Heterotopic pregnancy after a spontaneous conception a case report with a review of clinical, laboratory and imaging findings

Heterotopic pregnancy (HP) describes the simultaneous presence of two pregnancies at different implantation sites. Usually, one pregnancy is intrauterine and the other one is ectopic. The incidence of HP after assisted reproductive technologies reaches 1:3900, but is very rare after a spontaneous pregnancy, with a reported incidence of 1 to 30,000 pregnancies. Due to its rarity, complex clinical picture, and laboratory findings, it is challenging to diagnose HP. We present a case of spontaneous HP diagnosed in the first trimester by ultrasound (US) and magnetic resonance imaging (MRI) and subsequently managed successfully. We present an analysis of the clinical and laboratory findings as well as imaging, including MRI that we used to diagnose the condition. Additionally, we performed a literature review.

CONCLUSIONS

HP is a very rare condition frequently faced in obstetrics, gynecology, and emergency departments that requires a high index of clinical suspicion. US remains the imaging modality of choice in diagnosing a HP, however, in some cases, an MRI with a reported safety in the first trimester, can be used to provide additional information over US.

Anesthetic Management of a Patient With a Ruptured Heterotopic Pregnancy for Emergency Exploratory Laparotomy

Heterotopic pregnancy (HP) is an uncommon clinical condition characterized by the coexistence of intrauterine and extra-uterine pregnancies. HP is a diagnostic challenge as the typical methods for the early diagnosis of ectopic pregnancy are confounded by the simultaneous presence of intrauterine pregnancy (IUP). Ruptured HP is a potentially life-threatening obstetric emergency and can result in significant morbidity and mortality. Early diagnosis is the key to a favorable outcome. With the increasing number of patients undergoing artificial reproductive technology (ART), which is an important risk factor for HP, the odds of encountering HP patients are also growing. Anesthesiologists are challenged by the need to manage a bleeding obstetric patient while simultaneously ensuring the safety of the IUP. We present perioperative management of a patient with bleeding ruptured HP for emergency laparotomy who went on to have a successful twin delivery 37w3d via cesarean section.

A rare case of heterotopic pregnancy after a single embryo transfer: A case report and literature review

Heterotopic pregnancy (HP) is a rare but life-threatening disease. We report a rare case of HP that occurred after single embryo transfer (SET) with spontaneous natural pregnancy possibly due to sexual intercourse (SI) during assisted reproductive technology treatment and reviewed previous reports. A 39-year-old woman at 7 weeks 5 days' gestation with anti-sperm antibody who underwent a single frozen-thawed embryo transfer in her natural cycle presented with lower abdominal pain and vaginal bleeding. She had several SIs before the day of SET. A viable intrauterine fetus and an extrauterine mass at the right adnexa were detected on transvaginal ultrasonography. An emergent laparoscopic surgery showed a swollen right fallopian tube, and right salpingectomy was performed. Unfortunately, intrauterine fetal death was diagnosed at 19 weeks' gestation. In conclusion, the possibility of HP should be considered in patients with SIs around the day of SET.

The double corpus luteum: A novel sonographic sign of heterotopic pregnancy

Heterotopic pregnancy is a rare and highly morbid condition with simultaneous intrauterine and extra-uterine pregnancies. The early diagnosis of heterotopic pregnancy is difficult, owing to rarity of the condition and nonspecific clinical and laboratory findings. This case report introduces the "double corpus luteum" sign, a new sonographic and magnetic resonance imaging sign which is easily detectable and should raise the index of suspicion for heterotopic pregnancy. We present a surgically confirmed spontaneous heterotopic and angular pregnancy in a young woman without risk factors or assisted reproductive therapy to illustrate the utility of this novel sign.

Cervical heterotopic pregnancy: A case report

Heterotopic pregnancies are rare and difficult to be diagnosed early. A patient with combined intrauterine pregnancy and cervical pregnancy was admitted in Qingdao Municipal Hospital in 2019. The patient complained of abnormal vaginal bleeding after menopause and was misdiagnosed as simple intrauterine pregnancy. She underwent artificial abortion and suffered intraoperative hemorrhage. To stop bleeding, she received the treatment of uterine artery embolization immediately. Afterwards, cervical residual pregnancy tissues started necrosis, blood β-human chorionic gonadotropin level and the cervix appearance gradually returned to normal. This report suggests that cervical heterotopic pregnancy inclines to be mis diagnosed. Correct diagnosis should be made as soon as possible. Selective uterine artery embolization is an effective measure to prevent and treat massive bleeding.

Ruptured Heterotopic Pregnancy: A Rare Encounter in Acute Surgical Care Settings

Heterotopic pregnancy is a rare, life-threatening clinical entity with an overall incidence of about 1:30,000 in spontaneous natural conception cases, especially in cases of delayed diagnosis or conflicting clinical features. Here, we present an unusual case of heterotopic pregnancy in a 22-year-old multigravida presented to the emergency department (ED) with a clinical picture of the acute abdomen following recent abdominal trauma. Abdominal ultrasound revealed hemoperitoneum and a single viable intrauterine pregnancy at seven weeks' gestation. Following surgical exploration, the patient underwent removal of the ectopic pregnancy tissue with right salpingectomy. Since the presence of a conflicting history or equivocal physical signs and symptoms makes it difficult to diagnose heterotopic pregnancy, ED physicians and surgeons must consider the diagnosis even when dealing with viable intrauterine pregnancies. Besides, acute abdominal pain associated with shock should be regarded as suggestive of heterotopic pregnancy. Thus, prompt evaluation and a high index of suspicion are of paramount importance to prevent unwanted sequelae.

Tubal infertility and pelvic adhesion increase risk of heterotopic pregnancy after in vitro fertilization: A retrospective study

To analyze risk factors associated with heterotopic pregnancy and the uterine pregnant outcome of those patients after surgery.We retrospectively analyzed 22 patients diagnosed as HP after in vitro fertilization (IVF) between January 2015 and December 2018.HP was diagnosed at gestation age of 55.4 ± 11.8 days. HP were presented as irregular vaginal bleeding, abdominal pain, and sometimes no symptoms. 81.8% of ectopic lesion in HP occurred at fallopian tubes, especially ampullary; cornual pregnancy takes up 13.6%. Compared with clinical intrauterine pregnancy (IUP), IVF with tubal infertility factors had higher risks of HP (OR 4.185, 95% CI 1.080- 16.217); IVF with pelvic adhesion also had higher risks of HP (OR 5.552 95% CI 1.677-18.382); IVF with more than 2 embryos transferred increased risks of HP (OR 23.253, 95% CI 1.804-299.767). The abortion rates of surgery-treated HP and IUP after IVF were 27.8% versus 10.3% (P = .042).These results demonstrate IVF with tubal infertility, pelvic adhesion or multiembryos transfer are risk factors of HP. Furthermore, surgery could induce abortion.

Concurrent ruptured spontaneous heterotopic pregnancy and ruptured appendix with delayed presentation in the first trimester: a case report

Acute appendicitis is the commonest non-gynaecological surgical emergency in pregnancy. However, the concurrent occurrence of acute appendicitis with a heterotopic pregnancy is a rare event and presents diagnostic challenges to unsuspecting clinicians and sonographers. We present a case of a woman who had a heterotopic pregnancy and was noted to have a gangrenous appendicitis at laparotomy, illustrating how a diagnosis of acute appendicitis could easily be missed in pregnancy. We report the case of a 34-year-old woman in the first trimester of pregnancy who had a missed diagnosis of acute appendicitis after she had complained of vague abdominal symptoms for three weeks. She presented to a gynaecologist with vaginal bleeding for three days and was noted to have a heterotopic pregnancy on ultrasound scan. At laparotomy, she was noted to have a gangrenous appendicitis with pyoperitoneum concurrent with a ruptured left fimbrial ectopic pregnancy. Left salpingectomy and saline lavage were done and she had uneventful post-operative recovery. Unsuspecting clinicians, in patients without risk factors, can miss both heterotopic pregnancy and acute appendicitis. As assisted reproductive techniques become widespread, the possibility of heterotopic pregnancies must always be considered and any patient who presents with vague abdominal symptoms must be suspected to have the possibility of acute appendicitis. Because of the unreliability of laboratory investigations and clinical predictive scores in pregnancy, sonographers must be specifically asked to scan for heterotopic pregnancy and appendicitis in suspected cases.

Spontaneous Heterotopic Pregnancy: Case Report and Literature Review

Heterotopic pregnancy is defined as a condition when intrauterine and extrauterine pregnancy occur simultaneously. It is a life-threatening condition that requires immediate and accurate diagnostics and treatment. We present a case of a 28-year-old primigravida female who conceived spontaneously and at her seventh week of gestation and was presented to the emergency department with weakness and acute pain in lower abdomen. Laboratory tests and transvaginal ultrasonography revealed the diagnosis of heterotopic pregnancy. Urgent laparoscopic salpingotomy was chosen as a treatment option. The ectopic pregnancy was successfully removed with the preservation of the intrauterine embryo and fallopian tubes. The course of pregnancy after the surgery was without complications, and a healthy baby was delivered at the 39th week of gestation. When treated properly and on time, a heterotopic pregnancy can result in live childbirth with favorable outcomes for both the child and the mother.

Successful heterotopic pregnancy with prior radical trachelectomy after transabdominal cervico isthimic cerclage with methotrexate treatment

Heterotopic pregnancy with cervical incompetence is very uncommon. And yet there is no definite treatment for cervical incompetence occurring after radical trachelectomy. We are reporting a rare and novel case of a following in vitro fertilization combined intrauterine pregnancy and interstitial pregnancy which was successfully treated with maintenance of the pregnancy to term.

Two cases of intrauterine pregnancy with tubal stump pregnancy after in vitro fertilization and embryo transfer following ipsilateral salpingectomy: A case report

RATIONALE

The recently increased rate of heterotopic pregnancies (HPs) has been largely attributed to the increased use of assisted reproduction technologies (ARTs). HP is a rare and potentially life-threatening condition. It is unusual in natural conception cycles, occurring in 1:10,000 to 1:50,000 pregnancies. However, with the increased use of ART such as in vitro fertilization and embryo transfer (IVF-ET), the incidence has risen to 0.5-1%.

PATIENT CONCERNS

Case 1 was a 28-year-old woman who presented to our center complaining of a sudden onset of right-side lower abdominal pain with a small amount of vaginal bleeding. She had undergone IVF-ET and received a thawed embryo transfer with two embryos 23 days previously. She had a history of right salpingectomy for an ectopic pregnancy during the downregulation of her ovulatory cycle 1 year ago. Case 2 was a 25-year-old woman who presented to our center complaining of a sudden onset of right-side lower abdominal pain. She had also undergone thawed embryo transfer following IVF-ET with two embryos 35 days previously. She had a history of right salpingectomy for an ectopic pregnancy 1.5 years previously.

DIAGNOSES

Both patients were diagnosed as having a heterotopic pregnancy.

INTERVENTIONS

Patient 1 underwent emergency laparoscopy; patient 2 underwent emergency laparotomy and both were treated medically to prevent abortion of the intrauterine pregnancies.

OUTCOMES

Patient 1 had an incomplete abortion and underwent uterine curettage on the day 10 after the operation. Patient 2 experienced no further complications during pregnancy and a healthy baby girl was born at the 38th gestational week.

LESSONS

Reproductive physicians need to pay more attention to patients who have received more than one embryo at transfer, especially those with a history of salpingectomy.

The Management of Heterotopic Pregnancy with Transvaginal Ultrasound-Guided Local Injection of Absolute Ethanol

Aims:

The aim of the study is to present five cases of heterotopic pregnancy (HP) patients who received transvaginal ultrasound-guided local injection of absolute ethanol (AE).

Settings and Design:

This was a case series and literature review in Reproductive Medicine Center of the 105^th Hospital of the People's Liberation Army.

Materials and Methods:

Five primary infertile women who underwent assisted reproductive technology were diagnosed with HP and treated with local injection of AE (1.0–2.5 ml) under transvaginal ultrasound guidance. The size of intrauterine (IU) and ectopic sacs and the level of serum beta-human chorionic gonadotropin as well as pregnancy outcomes were monitored after treatment.

Statistical Analysis Used:

Not applicable.

Results:

Four of five cases presented with lack of Doppler flow in the injected area after AE injection. Meanwhile, IU pregnancy proceeded well after treatment and delivered a normal newborn. One case received emergency surgery 3 h after local injection of 2.5 ml AE because of the rupture of ectopic gestational sac (GS). An early abortion was identified 7 days after the surgery.

Conclusions:

Transvaginal ultrasound-guided local injection of AE is an alternative nonsurgical treatment for HP, yet overdose injection of AE will increase the risk of ectopic GS rupture.

Six Case Reports and Literature Review

Heterotopic pregnancy is defined as the simultaneous presence of intrauterine and ectopic pregnancies. It is a rare condition, but due to the increasing use of artificial reproductive techniques, the incidence of heterotopic pregnancy is increasing. Most of the patients with heterotopic pregnancy have a previous history of infertility or tubal diseases. In this case series, we are presenting six cases of heterotopic pregnancy. Three of them had a history of assisted reproductive technique: one patient had in vitro fertilization with three embryos transferred, and two patients received follicular stimulating hormone therapy. In one of the cases, heterotopic pregnancy was missed on an initial transabdominal scan, and in the following weeks, it was diagnosed on transvaginal ultrasound. Five patients underwent laparoscopic salpingectomy, and one patient had laparotomy and then a salpingectomy was done. Follow-up ultrasound scans for intrauterine pregnancy (IUP) showed abortion of the IUP, except in one patient who delivered a healthy full-term baby via spontaneous vaginal delivery. Therefore, there is a need to develop diagnostic criteria to rule out heterotopic pregnancy if the patient underwent any type of assisted reproductive techniques. We are emphasizing the need for more careful scanning of the adnexa via transvaginal ultrasound, especially in high-risk patients, even if the intrauterine gestation is confirmed.

Heterotopic Cervical Pregnancy: A Rare Case Treated by Transvaginal Aspiration

Cervical pregnancy is a rare form of ectopic pregnancy. Heterotopic cervical pregnancy is much more rare scenario. This is a case of Heterotopic cervical pregnancy treated successfully by transvaginal ultrasound guided aspiration.

A case of heterotopic pregnancy after clomiphene-induced ovulation

Heterotopic pregnancy is a rare condition in which both intrauterine and extrauterine pregnancies occur simultaneously. It was reported to be very rare in normal conceived pregnancy. However, with the considerable progress of the assisted reproductive techniques, the incidence of heterotopic pregnancy increased. Furthermore, the incidence also increases in previous abortions. In this case report, we will present and discuss a patient who had heterotopic pregnancy after clomiphene-induced ovulation as well as a history of previous abortion where the extrauterine fallopian tube ruptured and was managed surgically while the intrauterine pregnancy was preserved.

Heterotopic pregnancy Vital intrauterine pregnancy 12+4, vital ectopic pregnancy 11+4

OBJECTIVE

We present a case of a 32-year-old female patient, tertigravid after spontaneous conception with acute pain in the abdomen. It was a heterotopic pregnancy at 12 weeks of gestation, with late manifestation of clinical symptoms.

DESIGN

Case report.

SETTING

Department of Obstetrics and Gynecology, Silesian Hospital in Opava.

CONCLUSION

Heterotopic pregnancy is a rare, but potentially fatal complication of early pregnancy. The aim should be to remove the ectopic pregnancy while maintaining the vital intrauterine pregnancy. 76% of pregnancies in utero at the time of intervention for heterotopic pregnancy end in childbirth.

[A 36 weeks heterotopic pregnancy discovered incidentally at the Regional University Hospital of Ouahigouya]

Heterotopic pregnancy is a rare entity, its development up to term is exceptional. We report a case of heterotopic pregnancy of fortuitous discovery during a caesarean section performed in a 26-year-old female patient received for abdomino-pelvic pain on suspected twin pregnancy of 33 SA. No obstetric ultrasound had been performed before admission. Two ultrasound ultrasounds have objectified an intrauterine twin pregnancy with hydramnios. A caesarean section at 36 weeks indicated for twin pregnancy with hydramnios and severe anemia was performed during which we discovered an intrauterine pregnancy and an abdominal pregnancy with insertion of the placenta at the level of the broad left ligament with adhesion on the left annex, Omentum and small handles. Newborns did not require any special care outside the classical essential care. The first intrauterine had a weight of 2650 g and the second abdominal of 2000 g. The postoperative sequences were simple.

Ruptured ectopic in heterotopic pregnancy: Management and spontaneous vertex delivery of a live baby at term

Spontaneous heterotopic pregnancy is an uncommon clinical condition in which there is a simultaneous development of intrauterine and extrauterine pregnancies. It is a life-threatening emergency when the ectopic ruptures. We present Mrs. EC, a 27-year-old G₁P⁰ + ⁰ with a family history of multiple gestations who had a heterotopic pregnancy at a gestational age of 7 weeks. She presented with features of threatened miscarriage at early pregnancy with an ultrasound confirmation of intrauterine pregnancy. The diagnosis of ruptured ectopic pregnancy coexisting with intrauterine gestation was made with ultrasound findings as well as clinical features necessitating emergency exploratory laparotomy. Thereafter, pregnancy was carried to term, and she delivered a live male baby that weighed 3.0 kg. Heterotopic pregnancy should be sort for in all pregnancies during the early scan, especially in those with predisposing factors for multiple gestations and risk factors for ectopic gestation. A high index of suspicion is necessary for making a diagnosis in women with intrauterine pregnancy, with or without symptoms of ectopic gestation, and irrespective of the existence of risk factors for ectopic pregnancy.

The risk factors of miscarriage and obstetrical outcomes of intrauterine normal pregnancy following heterotopic pregnancy management

To investigate the clinical characteristics and risk factors for miscarriage of intrauterine normal pregnancy of patients with a heterotopic pregnancy (HP) after treatment.This was a retrospective study of medical records from CHA Bundang Medical Center. Sixty-four patients who were diagnosed with a HP between February 2006 and July 2017 were included in this study. All analyses were performed using SAS software, version 9.4 (SAS Institute, Inc., Cary, NC). P values < .05 were considered statistically significant.Forty-eight patients had tubal ectopic pregnancies (EP), 10 patients had cornual EPs, 1 patient had a cesarean section scar EP, 4 patients had an ovarian EP, and 1 patient had bilateral tubal EP. Among the 64 patients, 14.1% (9/64) miscarried before 10 weeks of gestation after management. Mean gestational age (GA) at treatment was 5.97 ± 0.50 weeks and 6.80 ± 1.04 weeks for miscarriage and nonmiscarriage group, respectively (P = .008). Significant differences were observed between 2 groups in terms of ultrasonographic features at the time HP was diagnosed (P = .040) Logistic regression models indicated that gestational age at treatment showed significant differences between 2 groups (OR: 0.003, 95% CI: 0.001-0.604).Immediate management after diagnosis could expect favorable prognosis of HP. GA at treatment was the only independent risk factor for miscarriage in patients with HP regardless of treatment methods.

Treatment of heterotopic caesarean scar pregnancy complicated with post termination increase in size of residual mass and morbidly adherent placenta

We report a case of a secundipara with heterotopic cesarean scar pregnancy (HCSP) treated with potassium chloride injection into the ectopic embryo followed by sac aspiration. The remaining "mass" increased in size threefold and was surrounded by a rich vascular network. An arteriovenous malformation was suspected; however, appropriate treatment was precluded because of the viability of the ectopic gestation. Sonographic examination revealed a morbidly adherent placenta, and attempt to resect the mass laparoscopically was complicated by bleeding that required hysterectomy. This case illustrates a complication of the intervention performed to preserve the intrauterine gestation in case of HCSP. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 46:227-230, 2018.

Heterotopic pregnancy in HIV women

Heterotopic pregnancy occurs when intrauterine and ectopic pregnancy are concomitant; overall rate rises from 1/30.000 to 1.5/1000 in assisted reproductive technology pregnancies. HIV (human immunodeficiency virus) patients are at increased risk of heterotopic pregnancies due to the greater frequency of assisted reproductive technology and pelvic inflammatory disease. We report the first case of heterotopic pregnancy in HIV woman.

Spontaneous uterine cornual rupture at 26 weeks' gestation in an interstitial heterotopic pregnancy following in vitro fertilization

Interstitial implantation in a heterotopic pregnancy is extremely rare, and despite currently available diagnostic modalities, early identification of an interstitial ectopic pregnancy remains difficult. This report describes a case of spontaneous cornual rupture at 26 weeks' gestation in a woman with diamniotic dichorionic twins that resulted in live births. The patient had previously undergone laparoscopic bilateral salpingectomy, and the pregnancy was conceived with in vitro fertilization. Interstitial implantation in a heterotopic pregnancy can go unrecognized, resulting in increased maternal and infant morbidity and mortality. © 2015 Wiley Periodicals, Inc. J Clin Ultrasound 44:322-325, 2016.

Heterotopic pregnancy with natural conception; a rare event that is still being misdiagnosed: a case report

Simultaneous presence of intra- and extra-uterine pregnancies have been known as heterotopic pregnancy (HP); the condition which is extremely rare with natural conception. Our aim is to increase the obstetrician's awareness to increase the level of positive outcome in such rare events.

Hypovolemic shock following induced abortion and spontaneous heterotopic pregnancy

Spontaneous heterotopic pregnancy is a rare clinical condition in which intrauterine and extrauterine pregnancies occur at the same time. It is rare, estimated to occur in 1 in 30,000 pregnancies. The case was a 38-year-old woman with spontaneously conceived heterotopic pregnancy. She was admitted to our center with hypovolemic shock. Focused assessment sonography for trauma examination in emergency department showed large amount of free fluid in peritoneal cavity. She was managed surgical laparotomy. Considering spontaneous pregnancies, physician should be aware of the possibility of heterotopic pregnancy in all reproductive age women, especially those with history of recent abortion. It can occur without any predisposing risk factors. Patients should be informed about possible side effects of nonprescription medicines, and also the health care centers must be safe peaceful environment for them without severe legal consequences.

[Successful treatment of a cervical heterotopic pregnancy following an in vitro fertilization procedure]

A 37-year-old nulligravida infertile female had a cervical heterotopic pregnancy following an in vitro fertilization procedure. Early intervention on the 6th week of gestation with a manual vacuum aspirator reached to remove the cervical pregnancy. Ligation of the descending cervical branches of the uterine arteries and a cervical cerclage, were placed before the aspiration, for prevention of possible hemorrhage. Successful removal of the cervical pregnancy was achieved with only mild bleeding. An intrauterine pregnancy progressed to viability without complications, resulting in a vaginal delivery of a preterm live-birth at 35.4 weeks, of a male that weighted 2740 g.
