RESUMEN

BACKGROUND: This study aimed to evaluate the umbilical cord blood chondroitin sulfate proteoglycan 4 (CSPG4) concentrations in pregnancies complicated with fetal growth restriction (FGR) and aimed to investigate the rela-tionship between the CSPG4 levels in these pregnancies and adverse neonatal outcomes. METHODS: This prospective case-control study was conducted between August 2023 and January 2024. The study included 80 singleton pregnancies at 35 to 39 weeks of gestation. Among these, 40 were diagnosed with FGR and 40 served as the control group. After the delivery, samples of the cord blood were collected prior to the placental delivery. RESULTS: The CSPG4 levels were significantly higher in the study group (FGR), 1,153 (1,059 - 1,261) pg/mL, than in the control group, 1,107 (873 - 1,197) pg/mL (p = 0.024). When all patients were evaluated, the CSPG4 levels showed a positive correlation with the systolic/diastolic (S/D) ratio of the umbilical arteries (r = 0.276, p = 0.013). A statistically significant negative correlation was observed between the levels of CSPG4 in the umbilical cord blood and the Apgar scores at the 1st (r = -0.256, p = 0.022) and 5th (r = -0.250, p = 0.026) minutes. The discriminatory power of the umbilical cord CSPG4 level in the determination of composite adverse neonatal outcomes was evaluated by ROC analysis and a cutoff point of > 1,091.25 pg/mL, showing a sensitivity of 93.3%, a specificity of 46.2%, and an AUC of 0.661 (95% CI: 0.547 - 0.763, p = 0.019). CONCLUSIONS: Elevated levels of CSPG4 have been observed in the umbilical cord blood in pregnancies complicated by FGR; higher levels are associated with adverse neonatal outcomes.

RESUMEN

Objective: This study aimed to investigate the effects of the presence of subchorionic hematoma (SH) in early pregnancies with threatened miscarriage (TM) on levels of first-trimester maternal serum markers, pregnancy-associated plasma protein-A (PAPP-A), and free ß-human chorionic gonadotropin (ß-hCG) levels. Methods: The data of TM cases with SH in the first trimester between 2015 and 2021 were evaluated retrospectively. The data of age and gestational age-matched TM cases without SH were also assessed to constitute a control group. Demographic characteristics, obstetric histories, ultrasonographic findings, and free ß-hCG and PAPP-A levels of the groups were compared. Results: There were 119 cases in the study group and 153 cases in the control group. The median vertical and longitudinal lengths of the SH were 31 mm and 16 mm. The median age of both groups was similar (p=0.422). The MoM value of PAPP-A was 0.088 (.93) in the study group and 0.9 (0.63) in the control group (p=0.519). Similarly, the MoM value of free ß-hCG was 1.04 (0.78) in the study group and 0.99 (0.86) in the control group (p=0.66). No significant relationship was found in the multivariate analysis between free ß-hCG MoM, PAPP-A MoM, age, gravida, and vertical and longitudinal lengths of the hematoma (p>0.05). Conclusion: The level of PAPP-A and free ß-hCG were not affected by the SH. Therefore, these markers can be used reliably in TM cases with SH for the first-trimester fetal aneuploidy screening test.

RESUMEN

OBJECTIVES: Placental abruption (PA) is associated with adverse maternal and neonatal outcomes and has an etiological mechanism that is not yet fully understood. The prediction of PA, which has been the subject of numerous studies, remains a challenge. In particular, there is evidence that PA can be considered a chronic process. So, this study aimed to show inflammatory biomarkers based on complete blood count parameters may be used to predict PA. STUDY DESIGN: A sample of 110 cases (pregnant women with PA) and 110 controls (healthy pregnant women with spontaneous labor) were required the study. The present case-control study included a total of 220 pregnant women. Inflammatory makers were used to evaluate the PA prediction RESULTS: Increases in body mass index, mean corpuscular volume and paletelet lymphocyte ratio are considered protective factors, while increases in neutrophil, the systemic inflammatory response index, neutrophil lymphocyte ratio and the pan-immune inflammation score are considered risk factors. Each 1 unit increase in neutrophil count increases the risk of a PA diagnosis by 1.81 times. CONCLUSION: Recent studies indicate a strong heterogeneity of clinical courses leading to PA in premature and term births. In the present study, our results showed that, inflammation is associated with PA.

RESUMEN

BACKGROUND: To investigate the association between late preterm antenatal corticosteroid treatment and outcome in late preterm neonates born to mothers with gestational diabetes mellitus, METHODS: All patients with gestational diabetes mellitus who had a late preterm delivery at Etlik Lady Zübeyde Hospital between 2017 and 2021 were included. Women who met the inclusion criteria and were not given antenatal corticosteroid treatment during current pregnancy before 34 0/7 weeks of gestation were divided into two groups according to whether or not they received late preterm antenatal corticosteroid treatment. The two groups were compared in terms of adverse neonatal complications. The main outcomes were composite respiratory outcome and composite neonatal outcome. Logistic regression analysis was used to determine additional potential predictors of neonatal outcome. RESULTS: This retrospective cohort study included a total of 400 participants with gestational diabetes mellitus who had a late preterm delivery within the study period. Of these women, 196 (49%) received late preterm antenatal corticosteroid treatment. Main outcomes showed no difference. Decreasing gestational age at birth was identified as an independent risk factor predicting both composite respiratory outcome and composite neonatal outcome in multivariate logistic regression analysis. CONCLUSIONS: Antenatal corticosteroid treatment at or after 34 0/7 weeks of gestation in women with gestational diabetes mellitus who had a late preterm delivery was not associated with improvement in adverse neonatal outcomes. Decreasing gestational age at birth was the only independent risk factor predicting composite neonatal and composite respiratory outcomes.

RESUMEN

INTRODUCTION: To determine a cut-off value for systemic immune-inflammation index (SII) (neutrophil × platelet/lymphocyte) in the prediction of fetal growth restriction (FGR). MATERIALS AND METHODS: This case-control study was conducted retrospectively at the Obstetrics-Gynecology and Perinatology Clinics of Etlik Zubeyde Hanim Women's Health Education and Training Hospital. Singleton pregnant women with late-onset FGR who were followed up in outpatient clinics or hospitalized and whose pregnancy resulted at our hospital were included in the study group (group I). Healthy early and full-term singleton pregnant women with spontaneous labor who were followed up in the same hospital and whose pregnancy resulted at the same hospital were included in the control group (group II). Receiver-operating characteristic curves were used to assess the performance of SII value in predicting FGR. RESULTS: We recruited 79 cases (pregnant with late-onset fetal growth restriction) and 79 controls (healthy pregnant), matched for age, body mass index, and parity. ΔSII was statistically significantly higher in the pregnant with late-onset FGR compared with healthy pregnant (123 vs - 65; p = 0.039). The values in ROC curves with the best balance of sensitivity/specificity were > 152 109/L (49% sensitivity, 70% specificity) and > 586 109/L (27% sensitivity, 90% specificity) for late-onset FGR. DISCUSSION: Higher ΔSII levels in maternal blood indicate an inflammatory process causing FGR. The cut-off value for ΔSII (> 586 109/L) at 90% specificity can be used as a screening test. In the presence of ΔSII levels > 586 109/L (27% sensitivity and 90% specificity), the physicians should be more cautious about risk for FGR. Therefore, pregnant women at risk for FGR should be checked more frequently and monitored closely. However, further studies are needed to confirm our findings.

RESUMEN

BACKGROUND: The goal was to investigate the change of systemic immune inflammation index (SII) in high-risk pregnant women diagnosed with intrahepatic cholestasis of pregnancy (ICP). METHODS: Between May 2018 and April 2020, we retrospectively enrolled 218 pregnant women who were followed in our hospital from the first trimester to delivery. We looked at the sociodemographics, laboratory data, SII values, Apgar ratings, and newborn birth weights of pregnant women with ICP. We also compared SII values in the first (SII 1), second (SII 2), and third trimesters (SII 3) between ICP and the control group. RESULTS: In the ICP group, the neutrophil level increased in the second trimester and decreased in the third trimester. The SII 2 was significantly higher in the severe ICP group, and when the SII values of the subgroups were examined, the SII 2 was significantly higher in the severe ICP group. The SII 2 showed a significant cutoff value for ICP with 92% sensitivity and 96% specificity. Again, a positive but weak correlation was found between SII 2 and SII 3 and FBA. When the neonatal outcomes were evaluated between the groups, gestational age at birth, birth weight and Apgar scores at 1 and 5 minutes were significantly lower in the ICP group. CONCLUSIONS: The relationship between SII and ICP was investigated for the first time in the literature and a significant cutoff value was found with the SII of the 2nd day. This showed that inflammation occupies an important place in the pathophysiology of cholestasis.

RESUMEN

PROBLEM: This study aims to investigate the role of the systemic immune-inflammatory index (SII) in inflammation by analyzing SII values by trimester in gestational diabetes mellitus (GDM). METHOD OF STUDY: Between May 2019 and June 2020, we retrospectively enrolled 467 pregnant women who were followed from the first trimester to delivery in our hospital. We evaluated the sociodemographic characteristics, laboratory test results, SII values, Apgar scores, and newborn birth weights of pregnant women diagnosed with GDM. We also compared the SII values of GDM for the 1st, 2nd, and 3rd trimesters with the control group. RESULTS: When examining the SII values of the GDM group in these three trimesters, without including the control group, we found that the SII value of the GDM group in the 3rd trimester was significantly higher than in the 1st trimester, with a gradual increase with each trimester (p = .007). Additionally, the SII value was higher in the GDM group compared to the control group (p = .008). We conducted a Receiver Operating Characteristic (ROC) analysis of the SII value between the groups by trimester. The diagnostic significance of SII between the GDM and control groups was observed in the 3rd trimester, as the area under the curve (AUC) was close to 0.5 and not associated with a specific cutoff value. When examining the relationship between 3rd-trimester SII and study parameters, we found it had a positive and low correlation with the length of prepartum hospitalization, 50 g Oral Glucose Tolerance Test (OGTT), and maximal vertical pocket. CONCLUSION: SII levels were significantly higher in third-trimester GDM patients; however, despite elevated levels of inflammation, fetuses did not experience harm.

RESUMEN

Objective: To determine factors affecting obstetric outcomes in pregnancies after conization by loop electrosurgical excision procedure (LEEP) or cold-knife conization (CKC) due to cervical intraepithelial neoplasia (CIN). Material and Methods: The maternal and clinical characteristics and obstetric outcomes of CKC, LEEP and control groups were evaluated and compared. Risk factors for adverse pregnancy outcomes were evaluated using multiple logistic regression analyses. Results: The incidence of preterm delivery, PPROM, low APGAR scores, fetal mortality, and late-period spontaneous abortus was highest in patients who underwent CKC (p<0.05). Cone depth of CKC was longer than LEEP (p=0.025). Cervical length (CL) at pregnancy was CKC

RESUMEN

OBJECTIVE: The aim of the present study is to compare the cavum septum pellucidi (CSP) z-score in euploid and aneuploid fetuses and to investigate the performance of the CSP width/length and CSP width/biparietal diameter (BPD) ratios as a diagnostic marker in aneuploidy. METHODS: A total of 54 patients, 20 aneuploid and 35 euploid fetuses, between 18 and 37 weeks of gestation, were included in this retrospective study. The CSP width z-score was compared between the two groups. Receiver operating characteristic (ROC) curves were calculated for the CSP width/length and CSP width/BPD ratios to predict aneuploidy. RESULTS: The median CSP width was 4.8 mm (range, 1.8 to 8.5 mm) in the euploid group, and 5.4 mm (range 3.1 to 8.4 mm) in the aneuploid group. Cavum septum pellucidi width z-score, CSP width/length ratio, and CSP width/BPD ratio were significantly higher in fetuses with aneuploidy than in fetuses with normal karyotype (p = 0.001; p = 0.013; p = 0.028). In the ROC analysis, the CSP width/length ratio had the optimal cutoff value of 0.59, with 72.0% sensitivity and 58.0% specificity, and for the CSP width/BPD ratio, the cutoff value was 0.081 with 83.0% sensitivity and 61.0% specificity for detection of aneuploidy. CONCLUSION: CSP width z-score was found to be increased in aneuploid fetuses. The CSP width /BPD ratio can be used as a new marker for predicting aneuploidy.

RESUMEN

Objective The aim of this study was to investigate the association between poor neonatal outcomes and BDNF (brain-derived neurotrophic factor) levels. We aimed to predict the need for an emergency cesarean and prevent unnecessary interventions in cases complicated with meconium-stained amniotic fluid (MSAF). Methods This study was designed as a case-control study including three groups. Group A included pregnant women who underwent cesarean due to fetal distress. Group B included the women who delivered vaginally. Groups A and B had cases with the presence of meconium in the amniotic fluid. Group C as a control group had clear amniotic fluid. Demographic features, fetal outcomes, and maternal serum and fetal cord blood BDNF levels (Human BDNF ELISA Kit; Synonyms: ANON2, BULN2; Catalog no: E-EL-H0010 96T) were evaluated. Results No significant difference was found between patients with meconium and without meconium in terms of BDNF levels. However, the BDNF level was found to be significantly lower if fetal distress had occurred with MSAF. Conclusions In conclusion, the study demonstrated that the level of maternal and fetal cord blood BDNF are both significantly lower when fetal distress occurs with the presence of MSAF.

RESUMEN

OBJECTIVE: Previous studies revealed that prenatal exposure to androgen excess such as polycystic ovary syndrome (PCOS) is associated with offspring's anogenital distance (AGD) length, and AGD is a biomarker of intrauterine androgen exposure. This study aims to investigate a possible relationship of fetal AGD with maternal diabetes and obesity, and to evaluate whether AGD predicts the fetal androgen exposure related to diabetes and obesity in female fetus. This study is the first to focus on the relationship between offspring's AGD and maternal diabetes and obesity. MATERIALS AND METHODS: This is a prospective study investigating 218 pregnant women (125 in control group and 93 in study group). Fetal AGD was measured from the center of anus to the posterior convergence of the fourchette by ultrasound. Multivariate linear regression analysis was applied to assess the association of the fetal AGD length with maternal diabetes and obesity. RESULTS: The control patients had significantly shorter fetal AGD (mean:10.7 mm, P < 0.001) compared to diabetic, obese and diabetic obese patients (mean: 12.6 mm, 12.8 mm and 12.9 mm, respectively). The results of regression analysis showed that both maternal diabetes and obesity were significantly correlated with longer AGD in female fetus. The results confirmed also that offspring's AGD measurement in utero by ultrasound is feasible and reliable. CONCLUSION: The study findings suggest that both maternal diabetes and obesity are associated with intrauterine androgenic milieu during pregnancy, and fetal AGD may be used as a biomarker to predict this effect. This may provide important advantages in terms of early detection of reproductive system abnormalities related to prenatal androgen exposure.

RESUMEN

Objective: The aim was to determine whether follow-up in the intensive care unit (ICU) for the postoperative first eight hours was beneficial for early intervention in postpartum hemorrhage. Material and Methods: In our hospital, all patients are admitted to the ICU for the first eight hours after cesarean section. Patients with postpartum hemorrhage after cesarean delivery who received medical and/or surgical treatment between 2016 and 2020 were reviewed in the presented study retrospectively. Results: All cases (n=36,396) who underwent cesarean delivery were reviewed. Three hundred and fifty-nine patients with postpartum hemorrhage were identified and included. In the study group the time between cesarean section and diagnosis of postpartum hemorrhage was 10.1±19.1 hours, and the time between cesarean section and re-laparotomy was 9.26±23.1 hours. A total of three maternal deaths occurred after cesarean section in our hospital. In the last five years, the mortality rate in patients delivering by cesarean section was 3.9 per 100,000. The incidence of postpartum hemorrhage in cesarean deliveries at our hospital was calculated to be 1.0%, and the rate of obstetric near-miss events was calculated to be 0.6 per 1000 live births. Conclusion: Follow-up of patients in the ICU in the first eight postoperative hours after cesarean section may result in a lower number of re-laparotomies due to postpartum hemorrhage, a shortened interval between cesarean section and re-laparotomy, and a lower maternal mortality rate.

RESUMEN

BACKGROUND: The aim of this study is to investigate the TyG index and TG/HDL-C ratio and their relationships with insulin resistance in LGA infants. METHODS: A prospective controlled study was conducted including 65 LGA and gestational age, gender-matched appropriate for gestational age (AGA) neonates. Serum TG, total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), insulin and glucose levels were measured within two hours after birth, TyG index and HOMA-IR values were calculated. RESULTS: TyG index and TG/HDL- C ratio were higher in LGA neonates compared to AGA ones (p = 0.03; p = 0.00, respectively). Compared with AGA newborns, LGA newborns had higher levels of insulin and HOMA-IR (p = 0.00; p = 0.00, respectively). TyG index and TG/HDL-C ratio showed moderate correlation with HOMA-IR (r = 0.59 R2 = 0.35 p < 0.001; r = 0.5 R2 = 0.25 p < 0.001, respectively). CONCLUSiON: The results of this study show that LGA newborns have increased levels of TyG index and TG/HDL-C associated with insulin resistance.

RESUMEN

Background: To evaluate cases diagnosed with fetal abdominal cyst diagnosed in prenatal period. Methods: We retrieved the cases diagnosed with fetal abdominal cyst between the years 2018 and 2020 from hospital's database. The localization, origin, dimensions, properties (simple or complex), and characteristics (solid, cystic, vascularity) were noted both in prenatal and postnatal period. We also tested the diagnostic performance of ultrasonography according to endpoint diagnosis revealed postnatally. Results: During the study period, a total of 29 cases diagnosed as fetal abdominal cyst. Of them, there were 11 (37.9%) gastrointestinal, 9 (31%) ovarian, 6 (20.6%) genitourinary, 3 (10.3%) hepatobiliary system cysts. In our study, we were able to identify 5 (45%) of 11 fetuses with postnatally confirmed gastrointestinal system cysts, 1 (33%) of 3 fetuses with hepatobiliary system cysts, 3 (50%) of 6 fetuses with urinary system cysts and 6 (66%) of 9 fetuses with ovarian cysts. Conclusion: In this study, the most common abdominal cyst was ovarian cysts. The most difficult to diagnose cysts are those that originated from gastrointestinal system and hepatobiliary system.

RESUMEN

OBJECTIVE: To study the value of fetal epicardial fat thickness (EFT) in gestational diabetes mellitus in the third trimester of pregnancy and its relationship with clinical parameters and perinatal outcomes. METHODS: A total of 80 participants, including 40 with diagnosed GDM and 40 healthy pregnant women, were included in the study. Demographic data were obtained from medical records. Sonographic examinations were performed, such as amniotic fluid value, fetal biometric measurements, and Doppler parameters of the umbilical artery. Fetal EFT values were measured at the free wall of the right ventricle using a reference line with echocardiographic methods. Correlation tests were performed to evaluate the relationship between fetal EFT and clinical and perinatal parameters. p < .05 were interpreted as statistically significant. RESULTS: The fetal EFT value was statistically higher in the GDM group than in the control group (p: .000). Spearman and Pearson correlation tests revealed statistically significant but weak positive correlations between fetal EFT value, 1-h 100-g OGTT, birth weight, and BMI (r: .198, p: .047; r: .395, p: .012; r: .360, p: .042, respectively). The optimal fetal EFT threshold for predicting GDM disease was found as 1.55 mm, with a specificity of 74.4% and sensitivity of 75.0%. Statistically significant differences between the two groups in umbilical artery Doppler resistance index (RI), pulsatility index (PI), and systolic/diastolic ratio (S/D) were not found (p: .337; p: .503; p: .155;). BMI and amniotic fluid volume were higher in the GDM group compared to the control group (p: .009; p < .01). CONCLUSION: This study demonstrated that increased fetal EFT may occur as a reflection of changes in glucose metabolism in intrauterine life. Future studies with larger series, including the study of neonatal metabolic parameters, will contribute to the understanding of the importance of fetal EFT in determining the metabolic status of the fetus.

RESUMEN

PURPOSE: The aim of this study was to measure placental stiffness with shear-wave elastography technique and to evaluate the relationship with cerebral-placental-uterine ratio (CPUR) and adverse perinatal outcomes in patient groups diagnosed with preeclampsia (PE) and fetal growth restriction (FGR) in the second and third trimesters compared to the control group. MATERIALS AND METHODS: This prospective cross-sectional study was conducted at our hospital between March 2019 and March 2020. The study groups were divided into three groups: PE, FGR, and low risk pregnancy (LRP) group. The study population had singleton pregnancies and the placental site was at the anterior wall. Both shear-wave elasticity (SWE) and shear-wave velocity (SWV) were measured in the placenta during pregnancy. CPUR was calculated for each group. RESULTS: A total of 147 patients were included in this study. The mean SWE (kilopascals) values in the PE group were significantly higher than in the FGR and controls (difference of means = 3.67, 9.45; 95% CI (1.23-6.1, 7-11.8); p < .05), respectively. The mean SWV values were significantly higher in PE and FGR groups than controls (p < .05). CPUR showed correlation with central maternal surface of placenta (p: .02, r: -0.184), central fetal surface of placenta (p < .001, r: -0.288), peripheral maternal surface of placenta (p: .002, r: -0.252), and peripheral fetal surface of placenta SWE values (p: .03, r: -0.181). NICU admission was correlated with central fetal surface of placenta SWE values (p: .002, r: 0.258). CONCLUSION: In conclusion, we demonstrated increased placental stiffness in both the PE and the FGR group. Also, this difference was found to be more prominent in preeclampsia. This technique seems useful for assessment of placental function and may strengthen the utility of Doppler parameters for predicting adverse perinatal outcomes in high-risk pregnancies.

RESUMEN

AIM: In this study, we aimed to investigate the role of systemic immune-inflammation index (SII) and other inflammatory parameters in the diagnosis of placenta accreta spectrum (PAS) and its histological subtypes. METHODS: This retrospective case-control study included patients who underwent surgery for placenta previa (PP). Case group (patients with PAS) included pregnant women diagnosed with histologically confirmed PAS, whereas control group (patients with PP) included pregnant women who underwent cesarean section with a PP diagnosis, required no additional intervention during the operation. Both groups were compared with respect to their demographic data, clinical characteristics, SII, and other laboratory parameters. Cut-off values that can predict PAS were calculated. The PAS group was separated into subgroups based on histology findings, and inflammatory parameters were compared between subgroups. RESULTS: In this study, data of 273 patients were analyzed. Of these, 68 (24.9%) were included in the PAS group and 205 (75.1%) patients were included in the PP group. Significant differences were observed in SII, platelet distribution width, mean platelet volume, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio (p = 0.000, p = 0.006, p = 0.002, p = 0.000, and p = 0.000, respectively). The best SII cut-off value was 985.02109/L (57.4% sensitivity and 72.2% specificity). There was no significant association between the histologic subtypes of PAS and inflammatory parameters. CONCLUSION: SII can be used to predict PAS in pregnant women with PP. The relationship between the histologic subtypes of PAS and inflammatory parameters should be investigated in more comprehensive studies.

RESUMEN

OBJECTIVE: The purpose of this study is to evaluate antioxidant balance in pregnant women with meconium-stained amniotic fluid. METHODS: Forty pregnant women with meconium-stained amniotic fluid and 40 pregnant women with non-meconium-stained amniotic fluid were included in the study. By checking the ischemia modified albumin (IMA) level and thiol/disulfide homeostasis in the maternal blood during labor and in newborn umbilical cord blood at the first minute after birth, antioxidant/oxidant balance was evaluated. RESULTS: No statistically significant difference was found between the maternal albumin levels. Maternal IMA level was statistically significantly higher in the meconium group than in the control group (p = .045). Maternal native thiol (SH) and maternal total thiol levels were statistically significantly higher in the control group than in the meconium group (p = .042 and p = .009, respectively). No statistically significant difference was found between maternal disulfide/native thiol (p = .262), maternal disulfide/total thiol (p = .152), maternal native thiol/total thiol (p = .153) rates in both groups. No statistically significant difference was determined between the patients with meconium and the control group in terms of cord blood IMA (p = .474), Albumin levels (p = .664), cord blood Native thiol (p = .944), cord blood total thiol (p = .612) levels and cord blood disulfide/native thiol (p = .240), cord blood disulfide/total thiol (p = .276), cord blood native thiol/total thiol (p = .277) rates. CONCLUSION: Determination of a decrease in SH and Total Thiol levels in maternal serum and an increase in the meconium group's IMA level was interpreted as a shift of antioxidant balance toward oxidant in this group.

RESUMEN

OBJECTIVE: The present study is intended to investigate the causes of stillbirth and its relationship with maternal conditions using the International Classification of Diseases-Perinatal Mortality (ICD-PM) system. MATERIAL AND METHODS: All early and late fetal deaths between 2015 and 2020 were analyzed. Time of death, fetal causes, and the maternal conditions involved were identified using the ICD-PM classification system. RESULTS: During the study period, out of 74,102 births a total of 475 stillbirths were recorded (6.4 per 1000 births), of which 83.6% of the cases were antepartum and 11.8% were intrapartum fetal deaths, and the time of death could not be determined in 4.6% of the cases. Fetal developmental disorder was the most common cause of antepartum fetal death (24.2%). Intrapartum deaths were mostly due to extremely low birth weight (44.6%). The most common maternal conditions involved were complications of placenta, cord, and membranes (19.8%). CONCLUSION: The applicability of the ICD-PM classification system for stillbirths is easy. It was observed that fetal deaths mostly occurred in the antepartum period and the cause of death could not be identified in over half of these antepartum fetal deaths. In over half of the stillbirths, there is at least one maternal condition involved. The most common maternal conditions involved are complications of placenta, cord, and membranes. The most common maternal medical problem is hypertensive diseases of pregnancy.
