RESUMO

OBJECTIVE: To compare the levels of oxidative stress markers in the umbilical cord blood between pregnant women diagnosed with iron deficiency anemia (IDA) and low-risk controls. METHODS: The sample consisted of 131 patients, including 55 pregnant women with IDA and 76 controls with similar demographic characteristics. Participants were selected from patients delivered at ≥37 weeks. We compared the two groups in terms of the native thiol, total thiol, disulfide, and ischemia-modified albumin (IMA) levels measured in pregnant women's umbilical cord venous blood. RESULTS: The native thiol and total thiol values were statistically significantly lower in the anemia group, and the disulfide and IMA values were statistically significantly higher in the IDA group (P < 0.001). Perinatal outcomes were similar between the groups. CONCLUSION: In the present study, pregnant women with IDA had lower native and total thiol values and higher disulfide and IMA values in umbilical cord blood. Iron deficiency anemia in pregnancy may be a potential cause of increased oxidative stress.

RESUMO

PURPOSE: To evaluate the utility of a novel ultrasound index "combined utero-cervical index (CUCI)" in the prediction of preterm delivery. METHODS: The present prospective cohort study was conducted in Ankara Bilkent City Hospital Perinatology Clinic between January 1, 2023, and March 31, 2023. Pregnant women with uterine contractions between 24 and 36th gestational weeks but did not have dilatation or effacement were included. CUCI was calculated as: (utero-cervical angle)/(anterior cervical lip thickness + fundal thickness + lower uterine segment thickness + cervical length). In the presence of cervical funneling, one point was added to the final result. A ROC analysis was conducted to determine the potential of CUCI in predicting delivery <37 weeks of gestation, <34 weeks of gestation, and <4 weeks after the first admission to the hospital for uterine contractions, respectively. RESULTS: Optimal cut-off values of CUCI were found to be 1.4 (67.1% sensitivity, 67.2% specificity) for predicting delivery at <37th weeks, 1.7 (72.7% sensitivity, 65.7% specificity) for predicting delivery at <34th weeks, and 1.4 (62.5% sensitivity, 61.7% specificity) for predicting delivery at <4 weeks. CONCLUSION: CUCI may be used in the prediction of preterm delivery for pregnant women admitted to hospital with preterm uterine contractions.

RESUMO

PURPOSE: The aim of this study was to evaluate perinatal outcomes between the uncontrolled asthma group and the mild asthma group and to reveal the relationship between disease severity and adverse maternal-fetal outcomes in this study. METHODS: This retrospective cohort study analyzed 180 pregnant women diagnosed with asthma, hospitalized, and delivered at our center between September 1, 2019, and December 1, 2021. We compared two groups: 160 with mild asthma and 20 with uncontrolled asthma. Data encompassed maternal characteristics, obstetrical complications, medication use, emergency department admissions for exacerbations, smoking status, and neonatal outcomes. RESULTS: In the uncontrolled asthma group, hospitalization rates, use of inhaled short-acting ß-agonist (SABA), and systemic corticosteroids were significantly higher compared to the mild asthma group (p < 0.01). Maternal and fetal complications were more prevalent in the uncontrolled group, including asthma exacerbations (45% vs. 1.2%), anemia (10% vs. 4.4%), prematurity (25% vs. 9.6%), and intrauterine fetal demise (IUFD) (10% vs. 0.6%). Neonatal outcomes in the uncontrolled group showed higher rates of admission to the neonatal intensive care unit (NICU) (50% vs. 25%), respiratory distress syndrome (RDS) (30% vs. 14%), and intraventricular hemorrhage (IVH) (5% vs. 0%) compared to the mild asthma group. CONCLUSION: Uncontrolled asthma during pregnancy is associated with higher adverse maternal-fetal and neonatal outcomes compared to mild asthma.

RESUMO

OBJECTIVE: Our study aimed to differentiate patients with placenta accreta spectrum (PAS) from those with placenta previa (PP) using maternal serum levels of vascular endothelial growth factor (VEGF), tumor necrosis factor-alpha (TNF-alpha), interleukin-4 (IL-4), and IL-10. METHODS: The case group consisted of 77 patients with placenta previa, and the control group consisted of 90 non-previa pregnant women. Of the pregnant women in the case group, 40 were diagnosed with PAS in addition to placenta previa and 37 had placenta previa with no invasion. The maternal serum VEGF, TNF-alpha, IL-4, and IL-10 levels were compared between the case and control groups. Then the success of these markers in differentiating between PP and PAS was evaluated. RESULTS: We found the VEGF, TNF-alpha, and IL-4 levels to be higher and the IL-10 level to be lower in the case group compared to the control group (p < 0.001). We observed a statistically significantly lower IL-10 level in the patients with PAS than those with PP (p = 0.029). In the receiver operating characteristic analysis, the optimal cut-off of IL-10 in the detection of PAS was 0.42 ng/mL). In multivariate analysis, the risk of PAS was significant for IL-10 (odds ratio (OR) 0.45, 95 % confidence interval (CI) 0.25-0.79, p = 0.006) and previous cesarean section (OR 2.50, 95 % Cl 1.34-4.66, p = 0.004). The model's diagnostic sensitivity and specificity, including previous cesarean section, preoperative hemoglobin (Hb), TNF-alpha, and IL-10 were 75 % and 72.9 %, respectively. CONCLUSION: The study showed that the IL-10 level was lower in patients with PAS than in those with PP. A statistical model combining risk factors including previous cesarean section, preoperative Hb, TNF-alpha, and IL-10 may improve clinical diagnosis of PAS in placenta previa cases. Cytokines may be used as additional biomarkers to the clinical risk factors in the diagnosis of PAS.

RESUMO

OBJECTIVE: This study aimed to investigate maternal serum vascular endothelial growth factor (VEGF) C and D levels in patients with intrahepatic cholestasis of pregnancy (ICP). METHODS: A total of 83 patients, including 41 patients with ICP and 42 healthy pregnant women, were included in the study. We first compared the maternal serum VEGF-C and VEGF-D levels between the ICP and control groups and then examined the correlation between the serum VEGF-C level and the bile acid level in patients with severe ICP. RESULTS: We observed statistically significantly higher serum VEGF-C levels and lower VEGF-D levels in the ICP group compared with the healthy controls (P < 0.001 and P = 0.015, respectively). According to receiver operating characteristic analysis, the optimal cutoff value for ICP was 147 ng/mL in the determination of the VEGF-C level (specificity and sensitivity: 76%). In patients with severe ICP, the serum VEGF-C statistically significantly correlated with the bile acid level (P = 0.019). CONCLUSION: This study showed that the maternal serum VEGF-C level was higher and the VEGF-D level was lower in patients with ICP compared with healthy pregnant women. We also found that the VEGF-C level was correlated with the serum bile acid level in patients with severe ICP. Serum VEGF-C level can be used in the diagnosis and follow-up of intrahepatic pregnancy cholestasis.

RESUMO

AIMS: The study aims to evaluate the genetic and clinical outcomes of fetal cardiac rhabdomyoma in our tertiary center. METHODS: Data of cases with cardiac rhabdomyoma detected by fetal echocardiography during antenatal follow-up were analyzed retrospectively. RESULTS: Nine cases were included in the study. The incidence of cardiac rhabdomyoma was 0.003%. The median fetal diagnosis time was 26th weeks, the most common location was the LV. There was no hemodynamic disorder requiring cardiovascular intervention in any of the cases. Of the eight genetically tested cases, four were tuberous sclerosis complex (TSC) gene-negative, one hereditary TSC2, one de novo TSC1, and two de novo TSC2 gene mutants. Postnatal first-year survival rate of the cases was 88.8%. CONCLUSIONS: Cardiac rhabdomyoma is a rare fetal and pediatric pathology that generally is a remarkable finding in the clinical process of TSC. Therefore, cases should be evaluated multisystemically and genetic counseling should be given to the family.

RESUMO

Objective: To demonstrate the impact of scoliosis on pregnancy and gestational outcome. Material and Methods: We retrospectively evaluated gestational outcomes of pregnant women with scoliosis at Hacettepe University Hospital between 2008 and 2018. Cases were grouped according to the presence of previous scoliosis surgery and compared in terms of gestational week at birth, birthweight, rate of neonatal intensive care unit admission, hospitalization during pregnancy, route of delivery, type of anesthesia at labor and postpartum intensive care unit admission rate. Ejection fraction (EF), functional vital capacity (FVC), forced expiratory volume (FEV1) and FEV1/FVC ratio values were also recorded. Results: A total of 23 women were included, of whom 12 (52.2%) had a prior scoliosis surgery. One of the 23 (4.3%) cases was terminated due to respiratory problems, while the remaining 22 cases resulted in deliveries. The median gestational week at birth was 38.2 and the median birth weight was 3150 g. Median (range) maternal height was 143 (80-160) cm while median (range) maternal weight was 51 (35-86) kg. Three (13.6%) were diagnosed with restrictive lung disease. No significant difference was found between operated and non-operated groups in terms of respiratory function test results, cardiac EF and other related demographic and clinical features. Overall cesarean delivery rate was 63.6% (14/22) and cesarean section rate was significantly higher in the operated group (83.3% versus 40%) (p=0.04). Conclusion: Cesarean section rate was increased in this cohort of pregnancies in women with scoliosis and who had previous scoliosis surgery.

RESUMO

INTRODUCTION: To estimate the possible role of VEGF-A in predicting poor early pregnancy outcomes including threatened abortion and early pregnancy loss. METHODS: We conducted a prospective case-control study with three groups of pregnant women diagnosed with threatened abortion, early pregnancy loss, and uncomplicated healthy pregnancies between 01 March 2023 and 15 March 2023. Maternal serum VEGF-A concentration was measured using the Sandwich-ELISA method in accordance to the commercial kit's instructions. There were 30 patients in each 3 group and the gestational age of the patients was between 6 and 14 weeks. The Kruskal-Wallis test was performed for comparing the median values between the groups. Mann-Whitney U test was conducted for pairwise comparisons. RESULTS: VEGF-A levels were compared between 3 groups and a statistically significant difference was found (p = 0.007). There was a moderately significant correlation between VEGF-A levels and poor early pregnancy outcomes. For poor early pregnancy outcomes, the area under the curve (AUC) was 0.75 (95% CI: 0.64-0.85). The best balance of sensitivity/specificity in ROC curves was 0.60 (63.3% sensitivity, 74.3% specificity). DISCUSSION: In conclusion, this study pointed out the increased VEGF concentrations in pregnant women with threatened miscarriage and early pregnancy loss. VEGF-A may be a potential biomarker for the indication of poor early pregnancy outcomes.

RESUMO

Abstract Objective To evaluate the fetal and maternal effects of the severe acute respiratory syndrome virus 2 (SARS-CoV-2) infection in women with hypertensive disorders of pregnancy. Methods Patients with hypertensive disorders of pregnancy and SARS-CoV-2 polymerase chain reaction (PCR) positivity (n = 55) were compared with cases with similar characteristics and PCR negativity (n = 53). The study group was further divided into two groups as severe (n = 11) and nonsevere (n = 44) coronavirus disease 2019 (COVID-19). The groups were compared in terms of clinical characteristics and perinatal outcomes. Results The study and control groups were similar in terms of maternal age, parity, gestational age at diagnosis, type of hypertensive disorders, magnesium sulfate administration rate, gestational age at birth, birth weight, Apgar scores, and maternal complications. However, all cases of fetal loss (n = 6) were observed in the SARS-CoV-2 positive group (p = 0.027). From the 6 cases, there were 5 in the nonsevere group and 1 patient in the severe SARS-CoV-2 positive group. Moreover, higher rates of maternal complications, lower oxygen saturation values, and intensive care unit admissions were observed in the severe COVID-19 group. Conclusion Physicians should be cautious about the management of hypertensive disorders of pregnancy cases with SARS-CoV-2 positivity. Fetal loss seems to be more common in cases with SARS-CoV-2 positivity and severe COVID-19 seems to be associated with higher rates of maternal complications. Close follow-up for fetal wellbeing and active management of severe cases in terms of maternal complications seem to be favorable.

RESUMO

OBJECTIVES: Our aim in this study was to evaluate the effect of antiepileptic drugs on biochemical components of screening tests. MATERIALS AND METHODS: This longitudinal case-control study was performed at Ankara City Hospital, Ankara, Turkey, from June 2020 to January 2021. The case group included epileptic singleton pregnant women which were using antiepileptic drugs, between 18 and 44 years of age. The control group included healthy pregnant women between 18 and 44 years old who did not use any drugs. Maternal medical, obstetric, and gynecological history were recorded. The antiepileptic agents that are used in our study were; lamotrigine, levetiracetam, carbamazepine, oxcarbazepine, valproic acid, and clonazepam. For the aneuploidy screening program conducted in our laboratory, the biochemical markers that are analyzed include; free b-hCG and PAPP-A in the first trimester, as well as AFP, HCG, and unconjugated estriol (uE3) in the second trimester. MoM values of these markers were compared between the case and control groups. RESULTS: Fifty-three pregnant women with epilepsy using antiepileptic drugs were compared with 106 healthy pregnant women. The levels of serum-free b-hCG, and PAPP-A were similar between the case and control groups (p = 0.653, p = 0.351). For the second-trimester screening biochemical markers, the maternal serum uE3 and AFP levels expressed as MoM were significantly higher in the epileptic group than in the control patients (p = 0.015 and p = 0.001). CONCLUSION: Serum marker levels of second-trimester screening tests may be affected by antiepileptic drugs, which may lead to misinterpretation of the risk level. Antiepileptic drug usage should be considered when evaluating screening test results.

RESUMO

INTRODUCTION: The aim of this study was to identify early changes in the Wnt/beta-catenin signaling pathway in high-risk human papillomavirus (HPV) infected cervicovaginal cells and to correlate these changes with cell proliferation, apoptosis, and autophagic processes. METHODS: We evaluated 91 cervicovaginal smears of women with (n = 41) and without (n = 50) HPV-DNA. Smears were stained against beta-catenin, c-myc, secreted frizzled-related protein 4 (sFRP4), cleaved caspase-3, and the autophagy markers Beclin-1 and light chain 3B. In addition, sFRP-1, -2, -3, -4, -5 mRNA levels were determined by quantitative reverse transcription-PCR in primary keratinocytes and FaDu cells expressing HPV16-E6, -E7, or -E6E7. RESULTS: Our data indicated that the Wnt/beta-catenin signaling is activated in HPV (+) cervicovaginal cells that can already be detected in cells with no obvious changes in cellular morphology (HPV [+]/cyto [-]). These cells also had significantly higher sFRP4 levels when compared to HPV-negative samples. In primary keratinocytes, sFRP4 was found to be absent and sFRP1 and sFRP2 to be repressed in the presence of HPV16-E6 and E7. Interestingly, sFRP4 is expressed in FaDu cells and can be upregulated in the presence of E6E7. Curiously, SFRP4 expression correlated with an increase in the level of autophagic markers in HPV (+)/cyto (-) smears. CONCLUSION: In conclusion, the activation of the Wnt/beta-catenin signaling pathway and upregulation of sFRP4, paralleled by an activation of the autophagic pathway may represent predisposing cellular factors early after HPV infection which need to be further determined in larger study.

RESUMO

OBJECTIVE: To introduce the effect of a single course of betamethasone for pregnant women at risk of preterm delivery (PTD). MATERIALS AND METHODS: In this study, a single course of 12 mg Bethamethasone was administered twice in 24 h (between 24-34 gestational weeks) for antenatal corticosteroid prophylaxis. Four hundred ninety-three neonates fulfilled the inclusion criteria and they were categorized (259 singletons, 192 twins and 42 triplets who met the inclusion criteria) into two groups according to the utilization of antenatal corticosteroid as control (n = 202) and study (n = 291) groups. We used respiratory distress syndrome (RDS), congenital pneumonia, intraventricular hemorrhage (IVH), neonatal sepsis, and bronchopulmonary dysplasia (BPD) as primary outcomes for the evaluation of neonatal morbidity. RESULTS: Study and control groups were similar in terms of clinical characteristics. RDS, congenital pneumonia, neonatal sepsis, and BPD rates were significantly higher in the study group (betamethasone) (p = .05, p = .007, 0.003, and 0.004, respectively) between 24-34 gestational weeks (when the neonates of multiple pregnancies were excluded from the analysis, we have demonstrated that congenital pneumonia (p = .033) and neonatal sepsis (p = .030) were still significantly higher in the betamethasone group). The neonates of 24-28 gestational weeks were compared separately and we demonstrated that RDS (p = .012), congenital pneumonia (p = .022), IVH (p = .044), neonatal sepsis (p = .023), and BPD (0.001) were also more frequent in the study group. When the 28-32 gestational week data were compared, IVH (p = .020) and neonatal sepsis (p = .017) were more frequent in the single course betamethasone users. However, we could not demonstrate a significant difference between the control and study groups between 32-34 gestational weeks in terms of the primary neonatal outcomes used in this study. CONCLUSION: Single course antenatal betamethasone administration may be ineffective on the respiratory complications of preterm and very preterm infants while it may be unfavorable for extremely preterm infants. WHAT IS NEW ABOUT THE PAPER, WHAT COULD ADD TO THE CURRENT KNOWLEDGE: Pregnant women at risk for preterm labor must be under intensive antenatal care programs, and if possible, necessary precautions must be undertaken to prevent fetal hypoxia together with etiology specific treatments. This approach might contribute to better perinatal outcomes than just administering antenatal corticosteroid therapy.

RESUMO

It was aimed to evaluate the levels of maternal serum proprotein convertase subtilisin/kexin type 9 (PCSK9) in pregnant women with a fetus diagnosed with open neural tube defects (NTDs). This case-control study included 38 pregnant women carrying fetuses with open NTDs and 44 age-matched, pregnant women with no specified risk factors. Comparisons were made of the groups in respect of demographic and clinical data and PCSK9 levels. To examine the performance of PCSK9 levels in the prediction of fetal open NTDs, receiver operating characteristic (ROC) curve analysis was used. In the first and second trimesters, PCSK9 levels were determined to be lower in the NTD group than in the control group (p = 0.010 and p = 0.015, respectively). In the first trimester, the lower PCSK9 levels in the NTD group were not statistically significant (p = 0.575). In the second trimester, the ROC curve value with the best balance of sensitivity/specificity for PCSK9 was 71.9 ng/ml (84.6% sensitivity, 51.7% specificity) and in the first and second trimester combined, 74.4 ng/ml (81.6% sensitivity, 45.5% specificity) (p = 0.015, p = 0.036, respectively). PCSK9 may be involved in the etiopathogenesis of open NTDs at the critical steps of fetal neuronal differentiation. Although it has limitations, PCSK9 may be used as an additional biomarker for the screening of NTDs.

RESUMO

Adequate maternal selenium level is essential for immune response and healthy pregnancy. This study aimed to shed light on the selenium status of pregnant women with COVID-19 and the effects of potential deficiency in serum selenium levels. Totally 141 pregnant women, 71 of them were COVID-19 patients, in different trimesters were included in the study. Maternal serum selenium levels, demographic and clinical parameters were determined. Serum selenium levels of pregnant women in the second (p: .0003) and third (p: .001) trimesters with COVID-19 were significantly lower than in the healthy group. Maternal selenium level was found to be negatively correlated with gestational week (p < .0001, r: -.541), D-dimer (p: .0002, r: -.363) and interleukin-6 (IL-6) level (p: .02, r: -.243). In the second trimester, serum selenium level positively correlated with white blood cell (p: .002, r: .424), neutrophil (p: .006, r: .39), lymphocyte (p: .004, r: .410) count and hemoglobin (p: .02, r: .323), hematocrit (p: .008, r: .38) status. In the third trimester, it was found that maternal selenium level positively correlated with monocyte (p: .04, r: .353) and negatively correlated with C-reactive protein level (p: .03, r: -.384). Serum selenium level was gradually decreased during the pregnancy period, however, this natural decrease was enhanced together with COVID-19 infection. The reason might be increased selenium needs depended on the immune response against infection. The decrease in maternal selenium level was found to be related to IL-6 and D-dimer levels, which indicate selenium's role in disease progression.

RESUMO

The aim is to compare VEGF-A values between pregnant women with coronavirus disease 2019 (COVID-19) and healthy controls. Furthermore, the association of inflammation parameters, disease severity, and obstetric complications with VEGF-A was investigated. This prospective case-control study was conducted on pregnant women who were admitted to Ankara City Hospital between June 14, 2020 and August 28, 2020. Pregnant women with COVID-19 (n = 95) were compared with a control group of healthy pregnant women (n = 92) with similar clinical and demographic characteristics. Demographic features, clinical characteristics, laboratory test results, VEGF-A values were compared between the groups. A correlation analysis was performed between VEGF-A levels, inflammation parameters, and clinical characteristics of the cases for pregnant women with COVID-19. VEGF-A levels were also compared between patients with composite adverse outcome and patients without any complication in the COVID-19 group. The two groups were similar except for obstetric complications (p > .05). The obstetric complication rate was higher in the COVID-19 group (p =.02). The two groups were comparable in terms of neutrophil to lymphocyte ratio and VEGF-A values. VEGF-A values were slightly different between the trimesters. A negative moderate statistically significant correlation was found between the neutrophil and VEGF-A values (r = -0.231, p =.02). VEGF-A values were similar between patients with and without composite adverse outcomes (p > .05). VEGF-A values were similar between pregnant women with COVID-19 and healthy controls.

RESUMO

AIM: To investigate the relationship of cholelithiasis and urolithiasis with Methylenetetrehydrofolate Reductase (MTHFR) polymorphism(s) in patients with poor obstetric history to search whether they are risk factors for adverse pregnancy outcome. MATERIALS AND METHOD: This study is consisted of 94 patients with poor obstetric history. Patients were evaluated in terms of the presence of cholelithiasis and urolithiasis in association with MTHFR polymorphism(s). Additional laboratory tests including homocysteine measurements were also performed. ROC analysis for assessing the performance of blood homocysteine level in predicting the presence of cholelithiasis and urolithiasis were also performed. RESULTS: Patients were divided into three groups such as cholelithiasis group (n = 9, 9.6%), urolithiasis group (n = 18, 19.1%) and control group (n = 67, 71.3%). Groups did not differ in term of age and Beksac obstetrics index (BOI) which is "[living child+(π/10)]/gravidity." The rate of the presence of MTHFR polymorphisms were 88.9% (8/9), 88.9% (16/18) and 43.3% (29/67) in cholelithiasis, urolithiasis and control groups respectively. Median homocysteine levels were found to be 13.1, 11.6 and 7.2 micromol/lt for the groups respectively. Statistically significant differences were found for MTHFR polymorphism rates and homocysteine levels (<0.001 for both). According to ROC analysis, 10.9 mcmol/L (88.9% sensitivity, 89.6% specificity) and 9.25 mcmol/L (83.3% sensitivity, 73.1% specificity) were determined to be cutoff values of homocysteine for cholelithiasis and urolithiasis respectively. CONCLUSION: More frequent MTHFR polymorphisms are observed in women with a clinical history of gall or renal stones. Thus, screening of these patients may be benefical for the approprate management of their subsequent pregnancies.

RESUMO

OBJECTIVE: To evaluate first trimester screening test parameters in epileptic patients using anti-epileptic drugs. MATERIALS AND METHODS: We retrospectively evaluated first trimester screening test results of 23 epileptic pregnant women using anti-epileptic drugs with a control group consisting of 92 healthy pregnancies. The anti-epileptic drugs used in this study were carbamazepine, levatiracetam, valproic acid and lamotrigine. Single drug or multi-drug regimens were used according to the clinical conditions. Patients with any known chronic or acute disease and drug usage were excluded from the study. Comparisons were performed via Mann-Whitney U test. RESULTS: First trimester screening test biochemical markers were compared and maternal serum PAPP-A MoM values were found to be similar in study and control groups while ß-hCG MoM values were significantly higher in pregnancies using epileptic drugs (p: 0,737 and p < 0.001, respectively). CONCLUSION: Biochemical first trimester screening test results may be affected by anti-epileptic drug usage, which may lead to misinterpretation of the risk level. Thus, validation of MoM values should be necessary in order to obtain optimal results.

RESUMO

We retrospectively evaluated five maternal mortality cases that occurred in our institution within the last 10 years. Rate of maternal mortality was 24.5 per 100000 live births. Maternal mortality causes were cardiopulmonary failure secondary to veno-occlusive disease, septic shock secondary to osteosarcoma, pulmonary thromboembolism secondary to metastatic breast cancer, septic shock secondary to cholecystitis, and postpartum hemorrhage secondary to Niemann-Pick disease. Four out of five cases were evaluated as indirect maternal mortality cases. Three out of five cases ended up with a healthy newborn, while other cases ended up with abortus and postpartum exitus.

RESUMO

OBJECTIVE: To evaluate the obstetric outcomes of singleton high-risk pregnancies with a small size uterine fibroid. METHODS: This retrospective cohort study was conducted among 172 high-risk pregnant women who were followed-up by a single surgeon between 2016 and 2019. Pregnant women with preconceptionally diagnosed small size (< 5 cm) single uterine fibroids (n = 25) were compared with pregnant women without uterine fibroids (n = 147) in terms of obstetric outcomes. RESULTS: There was no statistically significant difference between the groups in terms of adverse pregnancy outcomes. The size of the fibroids was increased in 60% of the cases, and the growth percentage of the fibroids was 25% during pregnancy. Intrapartum and short-term complication was not observed in women who underwent cesarean myomectomy. CONCLUSION: Small size uterine fibroids seem to have no adverse effect on pregnancy outcomes even in high-risk pregnancies, and cesarean myomectomy may be safely performed in properly selected cases.
