The effect of prophylactic uterine artery embolization on reproductive outcomes in patients with cesarean scar pregnancy: a propensity score-matched study.

PURPOSE: This study aimed to investigate the effect of prophylactic uterine artery embolization (UAE) on reproductive outcomes in patients with cesarean scar pregnancy (CSP). METHODS: A retrospective case-control study was conducted using the hospital records of all women diagnosed with CSP during a period of 6 years, between January 2014 and December 2019, at Shengjing Hospital of China Medical University. The clinical characteristics and different treatment modalities were analyzed. According to the inclusion and exclusion criteria, 181 patients with reproductive needs were selected and divided into a UAE group (n = 51) and a non-UAE group (n = 130) according to whether they received preventive UAE before their hysteroscopic or laparoscopic operation. The basic characteristics and pregnancy outcomes of patients in each group were compared, and a propensity score-matched (PSM) analysis was used to produce 37 matched pairs. RESULTS: Before PSM, the UAE group had a thinner muscle layer, larger mass size, and higher serum human chorionic gonadotropin level than the non-UAE group. The pregnancy rate and live birth rate of the UAE group were 54.9% and 61.9%, respectively, which were lower than those of the non-UAE group (61.5% and 66.7%), but no statistical differences were observed. Post-PSM, no significant differences between basic characteristics of the groups were observed. The pregnancy rate of the UAE group was 51.4%, which was lower than that of the non-UAE group (73.0%); the live birth rate of the UAE group was 64.3%, which was also lower than that of the non-UAE group (72.7%); however, the differences were not statistically significant with the P value of 0.077 and 0.716. CONCLUSION: Prophylactic UAE did not induce a significant difference in pregnancy rate and live birth rate between the UAE group and the non-UAE group.

[Cesarean scar pregnancy]. / Ectopische zwangerschap in litteken van keizersnede.

BACKGROUND: A rare, but potentially life-threatening complication of a Cesarean section is a so-called Cesarean scar pregnancy (CSP). This concerns an ectopic pregnancy, where the implantation takes place in a niche of the Cesarean section scar. CASE DESCRIPTION: We describe the case of a 29-year-old pregnant woman (G5P3), who after a amenorrhoea period of 6 weeks was referred to us by a midwife because the sonography showed an empty uterus. She had previously undergone two Cesarean sections. During transvaginal sonography we observed a small amiotic sac in the Cesarean section scar, lacking a clear heart rhythm. CONCLUSION: Since there are no general guidelines for the treatment of CSP, a patient-specific approach should be taken to determine optimal management. There is, however, a clear preference to terminate the pregnancy as soon as possible.

The Sustained Value of an Early Pregnancy Assessment Clinic in the Management of Early Pregnancy Complications: A 10-Year Retrospective Study.

OBJECTIVE: This study sought to evaluate the sustained value of an early pregnancy assessment clinic (EPAC) in the management of early pregnancy complications and its effect on the incidence emergency room (ER) visits. METHODS: A 10-year retrospective study (January 2006 to December 2015) was conducted. The number of patients assessed, sources and reasons for referral, and treatments provided were reviewed. The numbers of ER assessments and reassessments for abortion, hemorrhage, and ectopic pregnancy from January 2004 to December 2005 (pre-EPAC) and January 2006 to December 2015 (post-EPAC) were also reviewed. RESULTS: There were 11 349 new referrals and 10 764 follow-up visits. The reasons for referral were threatened miscarriage (n = 3568, 31.4%), missed miscarriage (n = 3056, 26.9%), incomplete miscarriage (n = 1064, 9.4%), complete miscarriage (n = 991, 8.7%), ectopic pregnancy (n = 857, 7.6%), hyperemesis gravidarum (n = 139, 1.2%), and others (n = 1674, 14.8%). There has been a significant decreasing trend (tau = -0.60, P = 0.0127) and a significant decrease in the post-EPAC rate of ER reassessments (P = 0.0396) for hemorrhage, with a concomitant decrease in EPAC visits for hemorrhage. In addition, there has been a significant increasing trend (tau = 0.64, P = 0.0081) and a significant increase in the post-EPAC rate of ER assessments (P = 0.00001) for ectopic pregnancies. CONCLUSION: Over the 10-year period, the EPAC has remained a vital service for managing early pregnancy complications for women. However, the clinic has not yet had a sustained impact on ER visits for miscarriage, ectopic pregnancy, and hemorrhage. It is possible that a reduction in ER assessments and reassessments for early pregnancy complications can be achieved through a clinic with daily access.

Successful medical treatment of a hepatic pregnancy: a case report.

BACKGROUND: Hepatic pregnancy is a rare form of abdominal pregnancy, often documented only as case reports. CASE PRESENTATION: We report here the case of a 24-year-old African woman, gravida 4 para 3, presenting with right upper quadrant pains and metrorrhagia after amenorrhea of 8 weeks 5 days. Elements in favor of the diagnosis of hepatic pregnancy were her clinical presentation, the kinetics of ß-human chorionic gonadotropin titers, and the presence of a sub-hepatic mass on ultrasound. We successfully treated this patient with intramuscular methotrexate only. CONCLUSIONS: The interest of this case resides in the rarity of this condition and the therapeutic approach used. Clinicians should raise their index of suspicion for hepatic pregnancy when faced with females of reproductive age with such a clinical presentation.

Pre-pregnancy and Early Prenatal Care are Associated with Lower Risk of Ectopic Pregnancy Complications in the Medicaid Population: 2004-08.

BACKGROUND: Ectopic pregnancy causes significant maternal morbidity and mortality. Complications are more common among women with Medicaid or no insurance compared to those with private insurance. It is unknown whether preventive care prior to pregnancy and prenatal care, which are covered by Medicaid, would decrease complications if they were more fully utilised. METHODS: Medicaid claims were used to identify a clinical cohort of women who experienced an ectopic pregnancy during 2004-08 among all female Medicaid enrolees from a large 14-state population, ages 15-44. Diagnosis and procedure codes were used to identify ectopic pregnancies and associated complications. The primary outcomes were complications associated with ectopic pregnancy: blood transfusion, sterilisation, or hospitalisation with length of stay greater than 2 days. Independent variables were documentation of preventive care within 1 year prior to the ectopic pregnancy and prenatal care within 4 months prior. RESULTS: Controlling for race, age, and state of residence, women's risks of any ectopic pregnancy complication were independently higher among those who did not receive any Medicaid-covered preventive care within 1 year before the ectopic pregnancy compared to those who did (RR 1.12, 95% confidence interval (CI) 1.09, 1.16), and among those who did not receive any Medicaid-covered prenatal care within 4 months prior, compared to those who did (RR 1.89, 95% CI 1.83, 1.96). CONCLUSIONS: Pre-pregnancy and prenatal care are independently associated with decreased risk of ectopic pregnancy complications among Medicaid beneficiaries.

Risk factors for recurrent ectopic pregnancy: a case-control study.

OBJECTIVE: To study the risk factors for recurrent ectopic pregnancy (REP). DESIGN: A retrospective case-control study. SETTING: A university medical centre. POPULATION: 554 women with a history of ectopic pregnancy (EP) were included. Among them were 181 women with current EP, 184 women with current intrauterine pregnancy (IUP) and 189 nonpregnant women (NonP). METHODS: The three groups were matched at a ratio of 1:1 with respect to current age, age of initial EP and gestational week of initial EP. Socio-demographic characteristics, reproductive history, gynaecological and surgical history, and experience of contraception were compared among the three groups. A multivariable logistic regression analysis was used to adjust for confounders and calculate adjusted odds ratios (AORs). RESULTS: The risk of REP increased with history of infertility (AOR = 3.84, 95%CI 2.16-6.86) in REP women compared with IUP controls. Compared with NonP controls, salpingotomy (AOR = 3.04, 95%CI 1.21-36.51) for previous EP was a risk factor for REP. Multiparous women were less likely to suffer REP when compared with NonP women (AOR = 0.36, 95%CI 0.18-0.62) or IUP controls (AOR = 0.35, 95%CI 0.20-0.62). Current use of an intrauterine device (IUD) (REP versus NonP, AOR = 0.02, 95%CI 0.00-0.08) or condoms (REP versus NonP, AOR = 0.16, 95%CI 0.07-0.38) significantly reduced the risk of REP compared with those not using any contraception. Similarly, previous use of condoms also prevented REP compared with those with no previous condom use (REP versus NonP, AOR = 0.20, 95%CI 0.08-0.49; REP versus IUP, AOR = 0.40, 95%CI 0.22-0.71). CONCLUSIONS: Women with history of infertility or salpingotomy should be alert for the recurrence of EP. Multiparous women are less likely to suffer REP. We propose the use of condoms for effective prevention of REP. TWEETABLE ABSTRACT: History of infertility and salpingotomy for last EP are risk factors for recurrent EP.

The serum brain-derived neurotrophic factor concentration prior to initiation of an in vitro fertilization cycle predicts outcome.

Our objective was to determine if the concentration of circulating brain-derived neurotrophic factor (BDNF) prior to cycle initiation predicts outcome in women undergoing in vitro fertilization (IVF). Stored serum samples from 226 women - 54 with a live birth, 45 with a spontaneous abortion, 38 with a biochemical pregnancy, 54 who did not become pregnant and 35 with an ectopic pregnancy- were retrospectively blindly tested for BDNF by ELISA. The median serum concentration of BDNF was highest in women with an extrauterine ectopic pregnancy (7.3ng/ml), intermediate in women whose embryos did not implant (5.5ng/ml) and lowest in women with a spontaneous abortion (4.2ng/ml), biochemical pregnancy (3.8ng/ml) or a live birth (3.6ng/ml) (P<0.0001). Among women with a positive pregnancy test an elevated BDNF level predicted an ectopic pregnancy with a sensitivity of 0.853 (0.689, 0.950) and a specificity of 0.949 (0.897, 0.979). We conclude that elevated BDNF in serum obtained before IVF cycle initiation is predictive of an extrauterine pregnancy.

Accuracy of first-trimester ultrasound in diagnosis of intrauterine pregnancy prior to visualization of the yolk sac: a systematic review and meta-analysis.

OBJECTIVES: To evaluate the diagnostic accuracy of ultrasound in predicting the location of an intrauterine pregnancy before visualization of the yolk sac is possible. METHODS: This was a systematic review conducted in accordance with the PRISMA statement and registered with PROSPERO. We searched MEDLINE, EMBASE and The Cochrane Library for relevant citations. Studies were selected in a two-stage process and their data extracted by two reviewers. Accuracy measures were calculated for each ultrasound sign, i.e. gestational sac, double decidual sac sign, intradecidual sign, chorionic rim sign and yolk sac. Individual study estimates were plotted in summary receiver-operating characteristics curves and forest plots for examination of heterogeneity. The quality of included studies was assessed. RESULTS: Seventeen studies including 2564 women were selected from 19 959 potential papers. Following meta-analysis, the presence of a gestational sac on ultrasound examination was found to predict an intrauterine pregnancy with a sensitivity of 52.8% (95% CI, 38.2-66.9%) and specificity of 97.6% (95% CI, 94.3-99.0%). The corresponding performance of the double decidual sac sign, intradecidual sign, chorionic rim sign and yolk sac were: 81.8% (95% CI, 68.1-90.4%) and 97.3% (95% CI, 76.1-99.8%); 66.1% (95% CI, 58.9-72.8%) and 100% (95% CI, 91.0-100%); 79.9% (95% CI, 73.0-85.7%) and 97.1% (95% CI, 89.9-99.6%); and 42.2% (95% CI, 27.7-57.9%) and 100% (95% CI, 54.1-100%), respectively. CONCLUSION: Visualization of a gestational sac, double decidual sac sign, intradecidual sign or chorionic rim sign increases the probability of an intrauterine pregnancy but is not as accurate for diagnosis as the detection of the yolk sac. However, the findings were limited by the small number and poor quality of the studies included and heterogeneity in the index test and reference standard.

Female tubal sterilization: the time has come to routinely consider removal.

Female sterilization, one of the most effective forms of pregnancy prevention, can be performed remote from pregnancy (interval sterilization) or around the time of delivery. Modern methods for sterilization include tubal interruption, salpingectomy, and transcervical sterilization. Tubal interruption has been the primary method for interval sterilization for decades, developing as a means of rapid intra-abdominal laparoscopic surgery at a time when instrumentation and operating systems were less sophisticated than today. New evidence that the most common ovarian cancer, serous adenocarcinoma, frequently may start in the Fallopian tube, has increased research and clinical use of salpingectomy as a preferred method for sterilization. With studies showing that the surgical risks with tubal interruption and salpingectomy are likely equivalent, even when performed at cesarean delivery, the rationale seems to be in place to change our clinical practice. However, we should ask why this revelation has not occurred sooner, even though surgical techniques have advanced and salpingectomy, unlike tubal occlusion or hysteroscopic sterilization, does not leave patients at risk for future intrauterine or ectopic pregnancy. We should not have started thinking about salpingectomy for female sterilization only once a decrease in ovarian cancer risk became part of the equation. Providers' failure to offer this option means that women and their true desires were not part of the conversation. If we had included the patient in the discussion, perhaps the higher efficacy of salpingectomy would have been what women desired all along.

Does methotrexate administration for ectopic pregnancy after in vitro fertilization impact ovarian reserve or ovarian responsiveness?

OBJECTIVE: To evaluate the effects of methotrexate (MTX) on the future fertility of women undergoing IVF by comparing ovarian reserve and ovarian responsiveness in the IVF cycle before and after an ectopic pregnancy (EP) treated with MTX. DESIGN: Retrospective cohort study. SETTING: Private reproductive endocrinology and infertility practice. PATIENT(S): Sixty-six women undergoing IVF before and after receiving MTX for an EP. INTERVENTION(S): Methotrexate administration and ovarian stimulation. MAIN OUTCOME MEASURE(S): Markers of ovarian reserve (day 3 FSH, antral follicle count), measures of ovarian responsiveness (duration of stimulation, peak E2 level, total dose of gonadotropins, number of oocytes retrieved, fertilization rate), and time from MTX administration to subsequent IVF cycle. RESULT(S): There were no differences after MTX administration in body mass index (BMI), FSH, or antral follicle count. A greater dose of gonadotropins was used in the cycle after MTX, but there were no differences in numbers of oocytes retrieved or high quality embryos transferred. As expected, there was a slight increase in age in the subsequent IVF cycle. The pregnancy rates (PR) were comparable to the average PRs within the practice when combining all age groups. CONCLUSION(S): Methotrexate remains the first line of therapy for medical management of asymptomatic EP and does not compromise ovarian reserve, ovarian responsiveness, or IVF success in subsequent cycles.

Proximal occlusion of salpinx by placing microcoil under X-ray brought a successful uterine pregnancy for a repeated ectopic pregnancy patient.

INTRODUCTION: This article provides a new method to avoid recurrent ectopic pregnancy during IVF-ET treatment in women who underwent bilateral salpingectomy. MATERIALS AND METHODS: A Chinese woman who underwent bilateral salpingectomy because of previous ectopic pregnancy sought IVF-ET therapy. She got two continuous salpingocyesis in fresh cycle and frozen cycle and received conservative therapy. We suggested her to undergo the laparoscopy to find the reason of repeated ectopic pregnancy. The patient declined due to economy and fear of operation. HSG showed that the length of the left and right salpinx was 3 and 4 cm, respectively. She received microcoil device under the X-ray guidance to induce proximal occlusion of the salpinx. Another FET was performed 3 months after this intervention and she succeeded this time and delivered a healthy infant finally. CONCLUSION: The proximal occlusion of the salpinx by microcoil device can be used to avoid ectopic pregnancy again during IVF-ET treatment in women who underwent bilateral salpingectomy.

Chlamydia public health programs and the epidemiology of pelvic inflammatory disease and ectopic pregnancy.

BACKGROUND: Many countries have witnessed a disturbing increase in cases of Chlamydia trachomatis infection despite enhanced control programs. Since the goal of Chlamydia control is to prevent reproductive complications such as pelvic inflammatory disease and ectopic pregnancy, an understanding of recent trends in these conditions is needed to fully evaluate the effect of control efforts. METHODS: We analyzed 2 provincial, comprehensive health services administrative databases (encompassing hospitalizations and all physician-delivered services) for pelvic inflammatory disease and ectopic pregnancy trends from 1992 through 2009 in women of reproductive age in British Columbia, Canada. Trends were compared to provincial Chlamydia surveillance data by time-series analysis, using the cross-correlation function method and Granger causality testing. RESULTS: Chlamydia cases substantially increased from 1992 through 2009. Inpatient, outpatient, and total diagnoses of pelvic inflammatory disease and ectopic pregnancy declined from 1992 through 2003. After 2003, pelvic inflammatory disease rates continued to fall, while ectopic pregnancy rates significantly increased. The male Chlamydia urethritis rate increased from 39.4 to 173.6 cases/100,000 from 1996 to 2009. CONCLUSIONS: In the context of increasing Chlamydia infection rates, the reproductive complications of Chlamydia infection in women are declining overall. A recent increase in rates of ectopic pregnancies is cause for concern.

Clinical effectiveness of multiple-drug injection treatment in unruptured ectopic pregnancies: a retrospective study.

OBJECTIVES: To study the effect of local interventional treatment of unruptured ectopic pregnancies with multiple-drug injection guided by color Doppler sonography. METHODS: In this retrospective analysis, 49 patients with an unruptured ectopic pregnancy were treated with two different local injection methods administered under sonographic guidance. The patients were divided into single-drug (n = 23) and multiple-drug (n = 26) injection groups, and they received a locally administered injection of methotrexate alone or a combination including methotrexate, hemocoagulase, antibiotics, and anti-inflammatory drugs, respectively. Overall, local injection treatment was successful in 44 patients. The 5 patients with failed treatment underwent laparotomy about 1 week after single-drug injection. Serum ß-human chorionic gonadotropin (ß-hCG ) levels, ectopic pregnancy mass sizes, blood flow at various points after treatment, the incidence of pelvic bleeding, and the time for serum ß-hCG levels to return to normal and the mass to resolve were analyzed in the remaining 44 patients. RESULTS: Single-drug treatment was successful in 18 patients; 10 of 23 had low to moderate pelvic bleeding after treatment, and 5 were referred for surgery. All 26 patients were successfully treated by multiple-drug injection. Only 2 patients had a small amount of pelvic bleeding. Differences between groups were statistically significant (P < .05) for surgery rates, the incidence of pelvic bleeding, transient increases in serum ß-hCG levels, mean days to normal ß-hCG levels, mean days of mass resolution, and mean mass diameters 1 to 6 weeks after treatment. CONCLUSIONS: Local multiple-drug injection under color Doppler guidance is a new, safe, and effective method for treating unruptured ectopic pregnancies. It accelerates the serum ß-hCG decline and facilitates mass resolution. This regimen is associated with a very low rate of pelvic bleeding, improves the success rate of conservative treatment, and, therefore, has value as an important clinical application.

Frozen-thawed embryo transfer is associated with a significantly reduced incidence of ectopic pregnancy.

OBJECTIVE: To compare the incidence of ectopic pregnancy (EP) after fresh ET and thawed ET. DESIGN: Retrospective cohort study. SETTING: Private fertility center. PATIENT(S): This retrospective study included 2,150 blastocyst transfers, including all 1,460 fresh autologous blastocyst transfers and all 690 transfers of autologous blastocysts derived from post-thaw extended culture of thawed bipronuclear oocytes in the 8-year study period 2004-2011. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Visualized EP and treated persistent pregnancy of unknown location. RESULT(S): The rate of visualized EP was 1.5% in pregnancies in fresh autologous cycles, which was significantly more than the rate of 0 with autologous post-thaw extended culture. The rates of treated persistent pregnancy of unknown location were 2.5% and 0.3% in these two groups, respectively, a difference that was also statistically significant (relative risk 7.3, 95% confidence interval 1.7-31.0). CONCLUSION(S): Relative to fresh transfer, thawed ET was associated with significantly reduced incidence of EP. These findings are consistent with ovarian stimulation increasing the risk of EP.
