RESUMO

Objective: The purpose of this study was to examine the recurrence rates of ovarian endometrioma, dysmenorrhea, dyspareunia, and related complications between sclerotherapy and laparoscopic ovarian cystectomy in individuals aged 25 to 38. Methods: Eighty-eight women participated in this retrospective, single-center study between January 2020 and February 2022. Patients received either laparoscopy or sclerotherapy, depending on the opinion of the pertinent physician. In this study, the following parameters were retrospectively analyzed in follow-up visits 2, 6 and 12 months after sclerotherapy and laparoscopy: dysmenorrhea and dyspareunia by visual analog scale, complications following the intervention, and serial pelvic sonograms for endometrioma cyst recurrence. Moreover, serum Anti-Müllerian hormone (AMH) level before and 6 months after sclerotherapy/surgery were analyzed. The collected data were then analyzed using R software. Results: The results demonstrate the efficiency of both sclerotherapy and laparoscopic techniques in reducing endometrioma-related dysmenorrhea and dyspareunia over a 12-month period. There was no statistically significant difference in the occurrence of complications and recurrence rate between these two therapies, and both are equally beneficial. Also, the rate of AMH decline after laparoscopy was higher than sclerotherapy; however there was not a statistically significant change in serum level of AMH in laparoscopy compared to the sclerotherapy after 6 months. Conclusion: Considering all the data, it appears that sclerotherapy, with its lower cost, shorter hospital stay, and quicker return to activities, can be a laparoscopic alternative to endometrioma cyst removal. More studies are required.

RESUMO

INTRODUCTION: Progesterone can be used instead of GnRH agonists and antagonists in order to avert a premature LH surge during controlled ovarian stimulation (COS) protocol. Nonetheless, there is limited knowledge regarding its utilization. Thus, this study compared the effects of progesterone and GnRH antagonists (GnRH-ant) on premature LH surges and assisted reproductive technology (ART) results in infertile women undergoing ART. MATERIALS AND METHODS: In this clinical trial, the progesterone protocol (study group) and GnRH-ant protocol (control group) were tested in 300 infertile individuals undergoing IVF/ICSI. The main outcome was the number of oocytes retrieved. The secondary outcomes included premature LH rise/surge, the quantity of follicles measuring ≥ 10 and 14 mm, oocyte maturity and fertilization rate, the number of viable embryos, high-quality embryo rate and pregnancy outcomes. RESULTS: The study group exhibited a statistically significant increase in the number of retrieved oocytes, follicles measuring 14 mm or greater, and viable embryos compared to the control group (P < 0.05). The study group also increased oocyte maturity, chemical pregnancy rate, and clinical pregnancy rate (P < 0.05). Both groups had similar mean serum LH, progesterone, and E2 levels on trigger day. The control group had more premature LH rise than the study group, although this difference was not statistically significant. CONCLUSION: In conclusion, it can be stated that the progesterone protocol and the GnRH-ant protocol exhibit similar rates of sudden premature LH surge in infertile patients. However, it is important to note that the two regiments differ in their outcomes in ART. TRIAL REGISTRATION: This study was retrospectively registered in the Iranian website ( www.irct.ir ) for clinical trials registration ( http://www.irct.ir : IRCT-ID: IRCT20201029049183N, 2020-11-27).

RESUMO

Astaxanthin (ASX) is a natural carotenoid compound found in several of microorganisms and seafood. It may have numerous therapeutic benefits for polycystic ovarian syndrome (PCOS) patients. The aim of this study was to investigate the effect of ASX on lipid profile, insulin resistance (IR), blood pressure (BP), and oxidative stress (OS) levels in infertile PCOS patients. Overall, 58 infertile women with diagnosed PCOS participated in this triple-blind randomized clinical trial. They were randomly assigned to two groups, taking either a placebo or ASX (2 × 6 mg/day) for 8 weeks. Blood serum samples were collected from patients before and after the intervention. Fasting Insulin (FI), fasting blood glucose (FBS), OS markers (malondialdehyde [MDA], superoxide dismutase [SOD], and total antioxidant capacity [TAC]), and lipid profiles were evaluated in serum. Moreover, based on the relevant formula, several indices associated with IR were calculated. BP was also assessed at the start and end of the study. After 8 weeks of ASX consumption, a significant reduction was observed in fasting blood sugar, HOMA-IR, FI, MDA, low-density lipoprotein-cholesterol, and TC/HDL-C. Conversely, ASX significantly increased TAC, HDL-C, and QUICKI. After adjusting the analysis for the baseline values of age, body mass index, and biochemical parameters, non-significant values were obtained for QUICKI and FI, along with no changes in other findings. Overall, ASX appears to be an effective and safe supplement that alleviates insulin metabolism, lipid profile parameters, and OS in infertile PCOS patients.

RESUMO

BACKGROUND: In a retrospective cohort of 881 women with gynecologic and unexplained infertility, we aimed to study the relationship between serum AMH levels and ART outcomes. This retrospective cohort includes 881 infertile women aged 20 - 45 who underwent their first fresh autologous non-preimplantation genetic diagnosis ART cycles between 2012 and 2020. METHODS: We assessed the correlation between AMH levels and reproductive outcomes among infertile women with different causes of infertility (including endometriosis, polycystic ovary syndrome (PCOS), and unexplained infertility). RESULTS: We found a strong correlation between high AMH levels and reproductive outcomes independent of age and the cause of infertility in women undergoing ART. In all patients with gynecologic and unexplained infertility, higher AMH correlated with the improved number of oocytes (p < 0.001), MII oocytes (p < 0.001), good-quality embryos (p < 0.001), chemical pregnancy rate (p < 0.001 in women < 37; and p = 0.002 in women over 37), clinical pregnancy rate (p < 0.05), and live birth rate (p = 0.05). CONCLUSIONS: Serum AMH concentrations can be invaluable for predicting ovarian reserve and reproductive outcomes in young and advanced-age infertile patients undergoing ART. However, it should not be used as the sole predictive marker for disqualifying infertile women from ART treatment. Further large cohort studies are warranted to determine an exact cutoff point for AMH to provide an accurate ART success prediction.

RESUMO

Astaxanthin (ASX), as a natural carotenoid compound, exists in various types of seafood and microorganisms. It has several possible beneficial therapeutic effects for patients with polycystic ovary syndrome (PCOS). Patients with PCOS also suffer from endoplasmic reticulum (ER) stress. In the present work, it was hypothesized that ER stress could be improved by ASX in PCOS patients. Granulosa cells (GCs) were obtained from 58 PCOS patients. The patients were classified into ASX treatment (receiving 12 mg/day for 60 days) and placebo groups. The expression levels of ER stress pathway genes and proteins were explored using Western blotting and quantitative polymerase chain reaction. To assess oxidative stress markers, follicular fluid (FF) was gained from all patients. The Student's t test was used to perform statistical analysis. After the intervention, ASX led to a considerable reduction in the expression levels of 78-kDa glucose-regulated protein (GRP78), CCAAT/enhancer-binding protein homologous protein (CHOP), and X-box-binding protein 1 compared to the placebo group, though the reduction in the messenger RNA (mRNA) expression level of activating transcription factor 6 was not statistically significant. However, ASX significantly increased the ATF4 expression level. GRP78 and CHOP protein levels represented a considerable decrease in the treatment group after the intervention. In addition, a statistically significant increase was found in the FF level of total antioxidant capacity in the treatment group. Based on clinical outcomes, no significant differences were found between the groups in terms of the oocyte number, fertilization rate, and fertility rate, but the ASX group had higher rates of high-quality oocytes, high-quality embryo, and oocyte maturity compared to the placebo group. Our findings demonstrated that ER stress in the GCs of PCOS patients could be modulated by ASX by changing the expression of genes and proteins included in the unfolding protein response.Trial registration This study was retrospectively registered on the Iranian Registry of Clinical Trials website ( www.irct.ir ; IRCT-ID: IRCT20201029049183N, 2020-11-27).

RESUMO

ABSTRACT Objective: To evaluate the effect of metabolic syndrome (MetS) diagnosis on oocyte quality and pregnancy outcomes in infertile women with polycystic ovary syndrome (PCOS) who undergoing antagonist-controlled ovarian stimulation (COS) and in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. Subject and methods: This prospective cohort study was conducted from November 2019 to November 2020 across two university-affiliated infertility centers in Iran. The PCOS diagnosis was defined according to the Rotterdam criteria. The patients prior to IVF/ICSI cycles were evaluated for MetS diagnosis. MetS was detected according to the National Cholesterol Education Program/Adult Treatment Panel III with the presence of at least three or more of the specific clinical criteria. The cycle outcomes were compared between MetS and non-MetS groups. Results: Overall, 68 eligible infertile PCOS patients with MetS diagnosis and 126 without MetS participated. The MetS diagnosis was associated with the increased requirement of gonadotropins and the COS duration significantly (P = 0.001). Although the total numbers of retrieved and MII oocytes, obtained and top-quality embryos as well as clinical pregnancy and live birth rates in the MetS group were lower than those of in the non-MetS group, the differences were not statistically significant (P > 0.05). In follow-up of the obstetrics complications, the rate of preeclampsia was significantly higher in patients with MetS (P = 0.02). Conclusion: MetS diagnosis in PCOS patients was associated with non-significant poor COS and pregnancy outcome. Further studies with larger sample sizes are recommended to clarify the risk of MetS in patients undergoing ART cycles.

RESUMO

BACKGROUND: The purpose of this prospective study was to compare the ovarian response and pregnancy outcomes
in the infertile women with endometrioma undergoing assisted reproductive technologies (ART) in two
groups, who were underwent laparoscopic cystectomy and received gonadotropin releasing hormone-agonist
(GnRH-agonist) and who only received GnRH-agonist without any surgery.
Materials and Methods: In this prospective clinical trial study, 79 infertile women with asymptomatic endometriomas
cyst (2-6 cm) were enrolled and randomly assigned to two groups. First group underwent laparoscopic
cystectomy and received GnRH-agonist. Second group only received GnRH-agonist without any surgery. Following
ovulation induction, all patients underwent intracytoplasmic sperm injection (ICSI). Different parameters
such as the number of retrieved oocytes and embryos; were made our outcomes that analyzed using SPSS.
Results: The pregnancy rate, chemical and clinical, and live birth rate were higher in the combined group,
although these differences were not statistically significant (48.48% vs. 30.8%, P=0.12, 36.36% vs. 25.6%,
P=0.32, 36.36% vs. 23.1%, P=0.29). The number of injections, antral follicles, retrieved oocytes, mature oocytes,
total embryos, transferred embryos and duration of stimulation were similar in two groups.
Conclusion: Laparoscopic cystectomy followed by receiving GnRH-agonist improves pregnancy outcomes in endometrioma
prior to treatment with ART (registration number: IRCT201106116689N2).

RESUMO

Objective: HCG (human chorionic gonadotropin), which is secreted by cytotrophoblast cells, plays an important role in improving pregnancy outcomes among patients with infertility or related problems. In this study, we evaluate the effect of intrauterine hCG injection prior to frozen embryo transfer on pregnancy outcomes. Methods: In this clinical trial study, among women with infertility problems referred to (XXX) and those with frozen embryos were included in the study. 155 patients in the intervention group received 500 units of hCG while 157 in control group received saline prior to embryo transfer. Along with demographic data, successful in vitro fertilization and clinical pregnancy, loss of pregnancy, successful transplantation, and biochemical parameters were compared among the two groups. Results: The mean age of the patients included in the study was 32.97 ± 3.31 years. The level of anti-Mullerian hormone, follicle stimulating hormone and the grade of frozen embryos were not significantly different between the two groups (P > 0.05). The rate of laboratory pregnancy in the intervention group was significantly higher than in the control group (51% vs 35%), p = 0.006. The rate of successful implantation and clinical pregnancy in the intervention group was also significantly higher, p = 0.01 and p = 0.006, respectively. Overall loss of pregnancy in intervention group was 78.1% and 86.0% in control group which was not significantly different, p = 0.068. Conclusion: The outcomes of our study showed that 500 IU of hCG prior to embryo transfer improves the rate of clinical and laboratory pregnancy. However, it does not reduce the rate of loss of pregnancy. Further studies are therefore required in this area.

RESUMO

Objective: This was a non-blinded randomized controlled study to evaluate whether endometrial irrigation via office hysteroscopy during the early follicular phase would lead to a higher level of live birth rates compared to no irrigation in the fresh embryo transfer cycle. Method: The study was conducted in Tehran university of medical sciences from June 2015 to June 2016. women under the age of 40 with primary infertility without history of previous IVF/ICSI or hysteroscopic examination, were included. Controlled ovarian hyperstimulation was done. Hysteroscopy was performed in the early mid-follicular phase of a stimulation cycle (day 5-7) with a vaginoscopy approach and saline irrigation in hysteroscopy group. Embryo-transfer was done in the same cycle. Results: 228 patients completed their participation in the study. In the fresh cycle, clinical pregnancy rate was 46% in the hysteroscopy group and 40.43% in the control group. (p-value= 0.326, RR= 1.16 [95%CI: 0.862 to 1.56]). Live birth rate was 41.28% in the hysteroscopic group and 31.93% in the control group (p-value=0.143, RR= 1.293 [95%CI: 0.916 to 1.825]). For those patients having surplus cryopreserved embryos, after 2 months, a second embryo transfer was performed. The cumulative LBR was 44.05% in the hysteroscopic group and 32.25% in the control group (p-value=0.029, RR= 1.368 [95%CI: 1.031 to 1.815], RD= 11.9% [95%CI: 1.2% to 22.3%] and NNT= 8 [95%CI: 4 to 85]). Conclusion: The current study clearly demonstrated a significantly higher cumulative live birth rate in the intervention group.

RESUMO

Polycystic ovary syndrome (PCOS) is the most prevalent endocrine disorder of women in reproductive age with significant effects on reproductive and metabolic functions. Many molecular players may be involved in PCOS pathology; however, miRNAs possess great ability in gene expression control in normal ovarian function and folliculogenesis. We appraised the relative expression of miR-146a, miR-222, miR-9, and miR-224 in serum and follicular fluid (FF) of PCOS patients compared to control subjects. PCOS (n = 35) and control (n = 30) subjects were recruited in the study during their enrolment in IVF cycles. Serum and FF of human subjects were collected and stored. Total RNA was isolated from samples and cDNA was synthesized using miRNA-specific stem-loop RT primers. Quantitative real-time PCR was used to evaluate the expression of miRNAs relative to U6 expression. The predictive value of miRNAs' expression for discrimination of PCOS patients from control subjects was evaluated by receiver-operating characteristic (ROC) curve analysis. miR-224 was not detected in serum and FF samples. Significantly, higher levels of miR-146a and miR-9 in serum of PCOS group were detected. In contrast, relative expression of miR-146a and miR-9 significantly decreased in FF. In PCOS group, relative expression of all detected miRNAs was elevated in serum in comparison to FF, whereas in control group no change was noticed. Combination of FF miRNAs showed improved predictive value with area under the ROC curve (AUC) of 0.84, 93.8% sensitivity, and 83.3% specificity. Contradicting alternations of miRNAs in serum and FF are indicative of different sources of miRNAs in body fluids. Presumptive target genes of studied miRNAs in signalling pathways may show the potential role of these miRNA in folliculogenesis.

RESUMO

OBJECTIVES: The aim of this study was to evaluate differences in clinical features and laboratory parameters in critically ill pregnant women with acute respiratory distress syndrome (ARDS) compared to moderate and severe pregnant women with coronavirus disease-2019 (COVID-19) but without ARDS. METHODS: This was a retrospective multicenter study of all pregnant women with COVID-19 diagnosed with ARDS between February 15, and May 1, 2020 in nine level III maternity centers in Iran (ARDS group). The control COVID-19 pregnant women were selected from 3 of 9 level III maternity centers between March 15 and April 20, 2020. Univariate statistics were used to look at differences between groups. Cluster dendrograms were used to look at the correlations between clinical and laboratory findings in the groups. A value of p <.05 was considered statistically significant. RESULTS: Fifteen COVID-19 infected women with ARDS were compared to 29 COVID-19 positive and ARDS negative control (moderate: (n = 26) 89.7% and severe: (n = 3)10.3%). The mean maternal age (35.6 vs. 29.4 years; p = .002) and diagnosis of chronic hypertension (20.0% vs. 0%, p = .034) were significantly higher in the ARDS group. There was no significant difference between the two groups in their presenting symptoms. The ARDS group had a significantly higher prevalence of tachypnea (66.6% vs. 10.3%, p = .042) and blood oxygen saturation (SpO2) <93% (66.6% vs. 10.3%, p = .004) at presentation. Relative lymphopenia (lymphocyte ratio < 10.5%, 66.6% vs. 17.2%, p = .002), lymphocytes to leukocytes ratio (11.3% vs. 17.7%, p = .010), and neutrophils to lymphocytes ratio (NLR) >7.5 were significantly different between the two groups (all p < .05). CONCLUSION: Our data demonstrate that symptom-based strategies for identifying the critically ill pregnant women with SARS-CoV-2 are insufficient; however, vital signs and laboratory data might be helpful to predict ARDS in critically ill COVID-19 pregnant patients.

RESUMO

BACKGROUND: COVID-19 has affected the training programs and the clinical schedules of surgical wards in many countries, including Iran. Also, the continuous involvement with COVID-19 patients has caused stress in health care workers; among them, residents are on the frontlines of care delivery. Therefore, we designed a study to assess the mental effects of these circumstances, and the effects on General Surgery and Obstetrics & Gynecology residency training in the busiest surgical departments of our university. METHODS: Participants of this cross-sectional study were residents of General Surgery and Obstetrics & Gynecology of Tehran University of Medical Sciences, and the conventional sampling method was used. We used a questionnaire consisting of 47 questions (mostly using multiple choice questions and answers on the Likert scale) about personal, familial, and demographic characteristics; training activities, and mental effects of COVID-19. RESULTS: The response rate was 63.5%. (127 filled questionnaires). Around 96% of the residents had emotional problems, 85.9% were highly stressed about contracting COVID-19, 81.3% were worried about transferring it to their families; and 78% believed that their residency training had been impaired. CONCLUSION: Overall, our study shows the negative impact of COVID-19 on mental health and the training of residents. We propose that appropriate emotional support and suitable planning for compensation of training deficits is provided for residents.

RESUMO

OBJECTIVE: Sulforaphane (SFN) is a natural free radical scavenger that can reduce oxidative stress (OS) through mediating nuclear factor (erythroid-derived 2)-like 2 (NF-E2-related factor 2 or NRF2)/antioxidant response element (ARE) signaling pathway and the downstream antioxidant enzymes. Here, we intended to study the role of SFN in OSinduced human granulosa cells (GCs) by investigating the intracellular levels of reactive oxygen species (ROS), cell death, and NRF2-ARE pathway. MATERIALS AND METHODS: This experimental study was conducted on GCs of 12 healthy women who had normal menstrual cycles with no history of polycystic ovary syndrome (PCOS), endometriosis, menstrual disorders, hyperprolactinemia, or hormonal therapy. After isolation of GCs, the MTT assay was performed to explore GCs viability after treatment with SFN in the presence or absence of H2O2. Flow cytometry was utilized to determine the intracellular ROS production and the apoptosis rate. Evaluation of the mRNA and protein expression levels of NRF2 and phase II enzymes including superoxide dismutase (SOD) and catalase (CAT) was performed by quantitative real-time polymerase chain reaction (PCR) and western blotting. Finally, the data were analyzed by SPSS software using One-way ANOVA and the suitable post-hoc test. Significance level was considered as P<0.05. RESULTS: Pretreatment of GCs with SFN attenuated intracellular ROS production and apoptosis rate in the H2O2-exposed cells. Moreover, SFN treatment increased the mRNA expression level of NRF2, SOD, and CAT. Higher expression of NRF2 and SOD was also observed at the protein level. CONCLUSION: Our study demonstrated that SFN protects human GCs against H2O2 induced-OS by reducing the intracellular ROS production and the following apoptosis through a mechanism by which NRF2 increases the antioxidant enzymes such as SOD and CAT. This result may have a potential application in assisted reproduction cycles by improving the quality of GCs and the embedded oocyte, especially in PCOS patients.

RESUMO

OBJECTIVE: To compare the clinical and paraclinical features and outcomes of pregnant and nonpregnant women with COVID-19. METHODS: A multicenter retrospective cohort study of pregnant and nonpregnant women of reproductive age hospitalized between March and October 2020 in Tehran, Iran. Medical records were reviewed and women who tested positive for SARS-CoV-2 on RT-PCR were included. Extracted data were compared and logistic regression performed. RESULTS: A total of 110 pregnant and 234 nonpregnant COVID-19-positive women were included. Frequency of severe disease was higher in nonpregnant women than pregnant women (29% vs 11.8%; P < 0.001). Symptoms including cough, dyspnea, chill, fatigue, and headache were more frequent in nonpregnant women (P < 0.05). Pregnant women had higher oxygen saturation levels and lower lymphocyte count (P = 0.001). Six (5.5%) pregnant and 12 (5.1%) nonpregnant women died (P = 0.80). No significant differences between the groups were found for ICU admission and end organ failure. Significantly more nonpregnant women had acute respiratory distress syndrome (ARDS, 9.4% vs 0%; P = 0.001). Univariate regression indicated association between hypertension and death; oxygen saturation and ARDS; and body mass index and ICU admission. No association was found between pregnancy and death, ICU admission, or ARDS. CONCLUSION: Pregnant women with COVID-19 are not at higher risk of adverse outcomes compared with nonpregnant women.

RESUMO

INTRODUCTION: Lack of reliable biomarkers for estimating the outcome is one of the current gaps in ART. In this study, we assessed whether cell-free mitochondrial DNA within the follicular fluid (FF cf-mtDNA) of PCOS patients has biomarker applicability or not. Furthermore, probable involved mechanisms in the FF cf-mtDNA pathway were evaluated. METHODS: The level of FF cf-mtDNA was compared between 50 PCOS patients and 50 women without any certain reproductive disorder, and analyzed for correlations with ART outcome. The associations between levels of FF cf-mtDNA and TFAM, POLG, and RNase H1 genes expression in mural granulosa cells (MGCs), as well as IL-6, and TNFα in follicular fluid (FF) were assessed. RESULTS: We identified that FF cf-mtDNA level was significantly lower in PCOS women and was accompanied by a reduction in the expression of mtDNA biogenesis genes in MGCs of the patients. Although a significant association between FF cf-mtDNA level and ART outcome was observed in the control group, no correlation could be proved in the PCOS group. Moreover, the expression level of TFAM was negatively associated, while amounts of IL-6 and TNFα were positively correlated with FF cf-mtDNA level in both groups. CONCLUSION: PCOS patients present a lower FF cf-mtDNA level in comparison with non-PCOS women. FF cf-mtDNA has biomarker applicability for ART outcome in women without any certain reproductive disorder, but not for those with PCOS. It seems that mtDNA packaging dysfunction results in elevated FF cf-mtDNA, and subsequent effects are triggered by increasing the inflammatory cytokines.

RESUMO

BACKGROUND: Despite 2.5 million infections and 169,000 deaths worldwide (as of April 20, 2020), no maternal deaths and only a few pregnant women afflicted with severe respiratory morbidity have been reported to be related to COVID-19 disease. Given the disproportionate burden of severe and fatal respiratory disease previously documented among pregnant women following other coronavirus-related outbreaks (SARS-CoV in 2003 and MERS-CoV in 2012) and influenza pandemics over the last century, the absence of reported maternal morbidity and mortality with COVID-19 disease is unexpected. OBJECTIVE: To describe maternal and perinatal outcomes and death in a case series of pregnant women with COVID-19 disease. STUDY DESIGN: We describe here a multiinstitution adjudicated case series from Iran that includes 9 pregnant women diagnosed with severe COVID-19 disease in their second or third trimester. All 9 pregnant women received a diagnosis of SARS-CoV-2 infection by reverse transcription polymerase chain reaction nucleic acid testing. Outcomes of these women were compared with their familial/household members with contact to the affected patient on or after their symptom onset. All data were reported at death or after a minimum of 14 days from date of admission with COVID-19 disease. RESULTS: Among 9 pregnant women with severe COVID-19 disease, at the time of reporting, 7 of 9 died, 1 of 9 remains critically ill and ventilator dependent, and 1 of 9 recovered after prolonged hospitalization. We obtained self-verified familial/household cohort data in all 9 cases, and in each and every instance, maternal outcomes were more severe compared with outcomes of other high- and low-risk familial/household members (n=33 members for comparison). CONCLUSION: We report herein maternal deaths owing to COVID-19 disease. Until rigorously collected surveillance data emerge, it is prudent to be aware of the potential for maternal death among pregnant women diagnosed as having COVID-19 disease in their second or third trimester.

RESUMO

BACKGROUND: Cervical ectopic pregnancy (CEP) is a rare and dangerous form of ectopic pregnancy in which the blastocyst is installed within the endo-cervical canal. CEP diagnosis requires special awareness to evaluate patient precisely. Individualizing controversial medical and surgical management strategies is of importance in medical practice. CASE: A 35-year-old nulliparous woman on her 9th week of pregnancy was referred to our hospital with vaginal bleeding preliminary misdiagnosed as aborting intrauterine pregnancy. Transvaginal ultrasound revealed an empty uterus and a viable triplet pregnancy just below the level of internal os. Cervical curettage after cerclage suture placement procedure removed conception tissues completely. Consequently, in the next few hours vaginal bleeding decreased to minimal amount and vital signs remained within normal limits and there was no hematocrit change. On follow-up day 32, serum B-HCG became negative. CONCLUSION: CEP diagnosis requires special attention and awareness to evaluate patient precisely along with skillful assessment of possible risk factors. Lifesaving treatment beside fertility preservation was successful with pre-curettage cerclage.
