Objectives Failure to increase cardiac output owing to suboptimal cardiac performance in obese women may contribute to placental hypoperfusion, and therefore subsequently to the abnormal placental development. The aim of this study was to evaluate the relationship between left ventricle (LV) function in overweight and obese pregnant women and parameters of blood flow in uterine arteries. Study design and main outcome measures We conducted a prospective cohort study, which included consecutive 87 women with singleton pregnancy − 56 women with normal weight and 31 overweight and obese women. During pregnancy blood pressure, echocardiography and the assessment of blood flow in uterine arteries - pulsatility index (PI) and resistance index (RI) were assessed on two visits (V): V1 between 10 and 14 weeks and V2 between 25 and 30 weeks of gestation. A stepwise logistic regression analysis was performed to determine the independent predictors of upper quartile of RI and PI during V2 in the study population. Results The multivariate logistic regression analysis showed that LVCI and LV mass measured on V1 were the only independent predictors of upper quartile of RI during V2, whereas LVCI was the only independent predictor of upper quartile of PI during V2. Conclusions Subclinical left ventricle dysfunction in obese and overweight women, present from the first trimester, may contribute to placental hypoperfusion and higher resistance in uterine arteries later during pregnancy. This may lead in some women to preeclampsia.

Preeclampsia (PE) is a condition characterized by high blood pressure and significant proteinuria in pregnant women. It affects about 7% pregnancies and can be cause of fetal and maternal morbidity and mortality. During pregnancy, a physiological overexpression of the Renin-Angiotensin System (RAS) components is observed, including increased plasma Ang II level. Dysregulation of RAS in placenta may contribute to preeclampsia and uterine growth retardation. The aim of the study was to evaluate the Ang I metabolism in human preeclamptic placentas and to compare to normal pregnancies condition.Fragments of placental tissues were collected right after ceasarian section from PE and physiological pregnancies. Tissues were incubated in Krebs buffer in the presence of Ang I. Evaluation of Ang I metabolites in incubating fluid was performed by LC/MS/MS method. mRNA expression of main RAS components was measured by RT-PCR.Pattern of angiotensin metabolites did not differ between groups. The main products were Ang 1-7 and Ang II. Comparing to control group, more than 3-fold lower production of Ang II and Ang 1-7 in preeclampsia was observed. mRNA expressions of ACE and AT1 were significantly decreased in pre- eclamptic placentas, whereas higher expression of mRNA of ACE2 and MAS receptor were observed.Production of Ang 1-7 by PE placentas was significantly lower than in control group. Significantly decreased mRNA expression of ACE and AT1 receptor and lower production of Ang II in placentas of PE patients suggest that placental Ang II/ACE/AT1r pathway could be less important than Ang 1-7/ACE-2/MASr pathway in development of preeclampsia, but this requires further investigations.

The aim of this study was to assess the performance of the International Ovarian Tumor Analysis (IOTA) group ultrasound Simple Rules method in differentiating between benign and malignant ovarian tumors in pregnant patients.A prospective observational study that involved pregnant patients referred to our center due to suspicions of ovarian masses between January 2015 and December 2017 was performed. The Simple Rules performance was evaluated against the histopathological results. Each of the 10 sonographic Simple Rules were computed by logistic regression to demonstrate their odds ratios in predicting malignancy.Ultrasound were conducted in 153 subjects, and 61 of those patients underwent surgery. By assigning masses presenting inconclusive picture as probably malignant, the Simple Rules method showed sensitivity of 91.67% and specificity of 69.39%. After exclusion of masses with inconclusive findings, the method showed sensitivity of 87.5% and specificity of 94.44%. The Simple Rules risk estimation method for the 1% risk cutoff showed sensitivity of 100% and specificity of 51.02%. For the 3% cutoff, sensitivity was 91.67% and specificity was 53.06%. And for 30 % cutoff, sensitivity was 91.67% and specificity 73.47 %. The logistic regression model showed that the M-rules increased the risk of malignancy while the B-rules decreased the risk.Most ovarian masses in pregnant patients may be correctly categorized as benign or malignant using Simple Rules. This protocol may facilitate the management of pregnant patients presenting with adnexal masses.

Objectives To identify the most common ultrasound patterns of markers and anomalies associated with Patau syndrome (PS), to explore the efficacy of multiparameter sonographic protocols in detecting trisomy 13 (T13) and to analyze the influence of maternal age (MA) on screening performance. Methods The project was a prospective study based on singleton pregnancies referred for a first-trimester screening examination. The scan protocol included nuchal translucency (NT), fetal heart rate (FHR), secondary ultrasound markers [nasal bone (NB), tricuspid regurgitation (TR), ductus venosus reversed a-wave (revDV)] and major anomaly findings. Results The study population comprised 6133 pregnancies: 6077 cases of euploidy and 56 cases of T13. Statistically significant differences were found in MA, FHR, NT, absence of NB, presence of revDV, TR and single umbilical artery. Fourteen cases of T13 (25%) demonstrated no markers of aneuploidy. The best general detection rate (DR) (DR of 78.6% with an false positive rate (FPR) of 1.2%) was obtained for a cutoff of 1/300 utilizing the “NT+T13” algorithm. The logistic regression model revealed that the central nervous system (CNS) anomalies had the greatest odds ratio (of 205.4) for T13. Conclusions The effectiveness of the multiparameter sonographic protocol used for T13 screening showed promising results in patients older than 36 years and suboptimal results in patients between 26 and 36 years old. When screening for T13 left heart defects, CNS anomalies, abdominal anomalies, FHR above the 95th percentile, increased NT, revDV and lack of NB should receive specific attention.

To compare the screening capability of ultrasonography in detecting trisomy 13 (T13) using a multiparameter sonographic protocol (NT+) with a classical combined screening test (CST) protocol.The project was a prospective, multicenter study based on a nonselected mixed-risk population of women referred for a first-trimester screening examination. Each subject was offered a choice between either the gold standard, traditional combined screening test (CSG arm) or the ultrasound-based screening protocol (USG arm). General and MA-based screening performances were checked.The study population comprised 20,887 pregnancies: 12,933 in the CSG arm, including 27 cases of T13, and 7954 in the USG arm, including 30 cases of T13. The DR for T13 was higher in the CSG arm than in the USG arm for all tested cutoff points: 1/50 (88.5 versus 63.3%, respectively), 1/100 (88.5 versus 70%, respectively) and 1/300 (92.3 versus 83.3%, respectively). Using the ROC curves for fixed FPRs of 3 and 5%, the T13 detection rate in our study reached 90 and 93%, respectively, in the USG arm and 92 and 96%, respectively, in the CSG arm. MA influenced the T13 screening performance in the USG arm and reduced the DR in patients31 years. Such influence was not detected in the CSG arm.Classic CST was more effective in detecting T13 than the ultrasound-only approach. However, the recommended cutoff of 1/50 showed unsatisfactory results for both traditional CST and the multiparameter sonographic test we proposed.

Early fetal cardiac scan (EFCS) is becoming an increasingly common element of the first trimester ultrasound screening carried out at 11-14 gestational weeks. It offers the first possibility to detect congenital heart defects (CHD) or, in ambiguous cases, to identify those pregnancies where a more detailed cardiac scan would be required later in pregnancy. The size of the fetal heart at the end of the first trimester and the associated relatively low image resolution make it impossible to capture all cardiac data to inform the ultimate picture. However, even at this stage, cues of anatomical and functional abnormalities can be picked up, which suggest not only a CHD, but also a likelihood of cardiovascular symptoms typical of genetic disorders. EFCS should focus on cardiac position, atrioventricular (AV) connections, AV valve function, initial assessment of ventriculo-arterial (VA) connections and the presence of red flag signs in the three vessel and trachea view (3VTV). Proper use of color Doppler mapping makes it possible to overcome the low resolution of B-mode to a certain extent. Here we present our long-term experience in EFCS.

Objectives The "Y sign" at the level of the 3-vessel and trachea view corresponds to thinning of main pulmonary artery and arterial duct and a dilated transverse aortic arch. The purpose of this study was to evaluate the Y sign for the diagnosis of aortic dextroposition anomalies at the time of the first-trimester scan and to assess the screening performance of only the Y sign, only abnormal left axis deviation (axis sign), and their combination for the diagnosis of aortic dextroposition anomalies. Methods A prospective evaluation of 6025 pregnant women undergoing first-trimester ultrasonography was conducted. The cardiac axis was measured in all examined patients and considered abnormal (positive axis sign) at greater than 57 °. The frequency of the Y sign and the axis sign was assessed for this population, and their screening performance for the diagnosis of aortic dextroposition anomalies was calculated. Results A total of 5775 patients fulfilled the inclusion criteria. Aortic dextroposition anomalies were diagnosed in 17 cases (tetralogy of Fallot in 8 and Fallot-like double-outlet right ventricle in 9). The Y sign was found in 18 of 5775 (0.3%) fetuses examined, of which 7 of 18 were confirmed with tetralogy of Fallot, 9 of 18 with a Fallot-like double-outlet right ventricle, and 2 of 18 with pulmonary stenosis. A positive axis sign of greater than 57 ° was found in 20 fetuses, including 4 with normal heart anatomy. The sensitivity values of the Y sign, the axis sign, and their combination were 94%, 76%, and 94%, respectively. Conclusions Visualization of the Y sign should increase the suspicion of aortic dextroposition anomalies in the late first trimester. The screening performance of the Y sign alone and in combination with an abnormal cardiac axis was high and may aid in the early diagnosis of aortic dextroposition anomalies in the fetus.

We present recommendations on performance and safety measures of ultrasound examinations in obstetrics and gynecology during the SARS COV-2 pandemic. The statement was prepared based on the current knowledge on the coronavirus by the Ultrasound Section of the Polish Society of Obstetrics and Gynecology. It has to be noted that the presented guidance is based on limited evidence and is primarily based on experiences published by authors from areas most affected by the virus thus far, such as China, Singapore, Hong Kong, and Italy. We realize that the pandemic situation is very dynamic. New data is published every day. Despite the imposed limitations related to the necessity of social distancing, it is crucial to remember that providing optimal care in safe conditions should remain the primary goal of healthcare providers. We plan to update the current guidelines as the situation develops.

To compare the screening performances of combined screening test risk algorithm for trisomy 18 (T18) using various cutoffs with a multiparameter ultrasound-based method. To compare the general and maternal age (MA)-based screening performances for T18 by means of combined screening and an ultrasound-based method.This was a prospective, multicenter study based on a mixed-risk non-selected population of women referred to referral centers for a first-trimester screening. Each subject was offered a choice between either a traditional combined screening (CSG arm) or an ultrasound-based screening (USG arm). General and MA-based screening performances were measured.The study population comprised 10 820 pregnancies as follows: 5132 in the CSG arm, including 28 cases of T18, and 5688 in the USG arm, including 29 cases of T18. In the CSG arm, the detection rate (DR) for T18 at a false-positive rate (FPR) of 3% was 86%, whereas the DR was 100% for the USG arm. MA influenced the T18 screening performance in the CSG arm and reduced the DR in MA ranges 26 years and 31-35 years. This influence was not observed in the USG arm.Only, a multiparameter ultrasound-based screening method may be considered an effective alternative to combined screening for T18 screening. The technique exhibits high and stable DRs irrespective of MA.

Autosomal dominant polycystic kidney disease (ADPKD) is one of most common inherited renal diseases. It is estimated that very early onset ADPKD affects even 2% patients. The purpose of this article is to provide a comprehensive review of genetics, prenatal diagnosis and prognosis in very early onset autosomal dominant polycystic kidney disease.

Objective: To evaluate the most common first-trimester ultrasound features of fetuses with trisomy 21 (T21) and to examine the screening performance for Down syndrome (DS) using only ultrasound-based protocols. To investigate whether maternal age (MA) has an impact on the efficacy of the ultrasound-based screening methods. Methods: In a prospective study, 6,265 patients were examined. Two ultrasound-based risk calculation protocols were applied: ‘NT' (based on nuchal translucency) and ‘NT+' (based on NT and secondary markers). Results: A total of 5,696 patients were enrolled for analysis; 84 subjects with T21 were identified. Combinations of abnormal ultrasound markers were observed in only 1.2% of euploid fetuses compared to 71.5% of fetuses with T21. Among 17.9% of DS cases with cardiac anomaly, 14.3% comprised atrioventricular septal defects. For a false-positive rate of 3%, the detection rates of T21 were 73.8 and 91.7% for the ‘NT' and ‘NT+' protocols, respectively. The efficacy of both methods was affected by MA. Conclusions: Most of the fetuses with DS demonstrate a combination of ultrasound markers of aneuploidy in the first trimester. The ‘NT+' protocol is efficient and provides comparable performance as a combined screening test. It is a valuable method, especially when the access to biochemical analysis is restricted.

Purpose: Among congenital brain anomalies, complete agenesis of the corpus callosum (cACC) including cases of callosal hypoplasia has a prevalence of 1.8 per 10 000 in the general population. It is also one of the most challenging brain anomalies to detect during the mid-trimester ultrasound scan. Standard axial planes do not provide enough information to make the definitive diagnosis of cACC. Materials and Methods: From our library of images and ultrasound reports, we reviewed our most recent cases of complete agenesis of the corpus callosum in the fetus at the mid-trimester scan. In our analysis we included only cases that were confirmed postnatally or by autopsy. Exams were performed between January 2010 and June 2012. All of the patients were scanned transabdominally by means of 2 D and static 3 D. From the 2 D and 3 D images we identified 4 anatomical views that consistently gave us enough information to identify cACC: axial biparietal transthalamic view (AX1); axial biparietal falx view (AX2); coronal transthalamic view (COR); mid-sagittal view (SAG). Results: From our library 30 cases were selected with confirmed cACC postnatally or in autopsy findings. The mean gestational age at the time of referral to our center was 20.7 weeks (range 19 – 23 weeks). In all analyzed cases sufficient 2 D images were found and in 93.3 % of them informative 3 D volumes were also available for off-line review. We identified the following patterns of cACC at the mid-trimester scan: A- normal size of 3 rd ventricle + normal size of the lateral ventricles or mild ventriculomegaly; B1- dilated 3 rd ventricle + normal size of the lateral ventricles; B2- dilated 3 rd ventricle + mild or moderate ventriculomegaly; C- dilated 3 rd ventricle + severe ventriculomegaly; D- gross dilatation of 3 rd ventricle with the appearance of interhemispheric cyst. The AX1 view revealed: absence of the cavum septum pellucidi in all cases; dilatation of the third ventricle in 86.6 % of cases; separation of frontal horns in 83.3 % of cases; ventriculomegaly in 73.3 % of cases, including 13.6 % with severe forms. The AX2 view showed separation of the interhemispheric fissure (IHF) in 90 % of cases and upward displacement of the 3 rd ventricle in 80 % of cases. The COR view confirmed separation of the interhemispheric fissure in 90 % of cases including gross separation in 7.4 % of cases; absence of CC fibers at this level and descent of the falx towards the roof of the 3 rd ventricle in all cases, and upward displacement of the 3 rd ventricle in 80 % of cases. The SAG view revealed the absence of the CSP-CC complex in all cases and dilatation of the 3 rd ventricle in 86.6 % of cases. Conclusion: 1. We suggest a stepwise ultrasound diagnostic approach for cACC and variations of this condition. 2. We suggest a classification of characteristic patterns found in fetuses with proven cACC based on findings presented in axial views.

Background: During pregnancy the cardiovascular system undergoes complex alterations; however, there have been few studies concerning pulmonary artery behaviour during gestation. Aim: The aim of this study was to evaluate changes in the pulmonary artery diameter (PAD) during gestation, with respect to left ventricular (LV) load and remodelling, as well as to systemic vascular resistance (SVR). Methods: It was a prospective cohort study, which included 69 consecutive healthy outpatient women with a singleton pregnancy. Echocardiography and ultrasonography of the uterine arteries were performed at two visits (V1 and V2) during pregnancy, and only echocardiography at one visit postpartum. Results: Pulmonary artery diameter increased in all women, from 20.0 mm at V1 to 22.7 mm at V2 (p < 0.001), and it returned to the reference range postpartum (19.5 mm; p < 0.001 vs. V2). Echocardiography did not reveal any other abnormalities, including the signs of intracardiac shunt or right ventricular pressure overload. During V2, PAD positively correlated with the following echocardiographic parameters: LV end-diastolic diameter (r = 0.386; p = 0.002), LV end-systolic diameter (r = 0.345 p = 0.006), LV end-diastolic volume (r = 0.308; p = 0.016), LV mass (r = 0.459; p < 0.001), left atrial area (r = 0.334; p = 0.009), LV cardiac output (r = 0.338; p = 0.011), and aortic diameter (r = 0.369; p = 0.003). Furthermore, there was a negative linear correlation between PAD and SVR (r = –0.307; p = 0.025) and pulsatility index (r = –0.318; p = 0.012). Conclusions: Our study shows pulmonary artery dilatation in healthy pregnant women without any other abnormal echocardiographic findings. These changes in PAD are associated with volume overload and low vascular resistance, and during postpartum they usually subside.

Study question What is the diagnostic accuracy of 2D/3D hysterosalpingo-foam sonography (HyFoSy) and 2D/3D-high-definition flow Doppler (HDF)-HyFoSy in comparison to laparoscopy with dye chromotubation (as the reference method) and 2D air/saline-enhanced hysterosalpingo-contrast sonography (HyCoSy) (as the initial index test)? Summary answer 2D/3D-HDF-HyFoSy had the best diagnostic accuracy and was the only method that did not significantly differ from the reference method, while both 2D/3D-HyFoSy and 2D/3D-HDF-HyFoSy had significantly higher accuracy than 2D-air/saline-HyCoSy. What is known already Previous studies on X-ray hysterosalpingography and laparoscopy and dye as the reference standard have undermined the impact of older commercial contrast agents on the accuracy of ultrasound tubal patency tests. Recently, HyFoSy was reported to have very high accuracy in a small pilot study in comparison to laparoscopy and dye, and had a very high positive predictive value (PPV) for medical tubal occlusion. A new Doppler sonographic technique, known as HDF imaging with better axial resolution, fewer blooming artifacts and higher sensitivity than color and power Doppler imaging, has been introduced. Study design, size, duration A prospective observational study was performed on 132 women (259 Fallopian tubes) consecutively enrolled between 2013 and 2015. Participants/materials, setting, methods This study included infertile women of reproductive age who previously had not been examined for tubal patency and who presented for the evaluation to the university hospital, private hospital and clinic at which this study was conducted. 2D-Air/saline-HyCoSy, 2D/3D-HyFoSy and 2D/3D-HDF-HyFoSy and laparoscopy were performed independently by experienced readers. During HyFoSy, the 3D mode was used for standardization of pelvic scanning and observations of contrast flow without diagnosis after volume acquisition. Sensitivity, specificity, negative and positive predictive value (NPV and PPV), negative and positive-likelihood ratio (LR- and LR+) and 95% CI were calculated. McNemar's test and relative predictive values (a comparison of NPV and PPV) were used to compare all the index tests. Main results and the role of chance 2D-Air/saline-HyCoSy, 2D/3D-HyFoSy and 2D/3D-HDF-HyFoSy indicated that 46 (17.8%), 27 (10.4%) and 24 (9.2%) of the 259 tubes were occluded, respectively; additionally, inconclusive results were obtained for 8 (3%), 5 (1.9%) and 3 (1.2%) tubes, respectively. The reference method revealed 18 (6.9%) occluded Fallopian tubes. 2D-Air/saline-HyCoSy had a high NPV (99.5%) that was similar to that of 2D/3D-HyFoSy (99%) and 2D/3D-HDF-HyFoSy (99.6%) (P > 0.05), but had a very low PPV (30.4%). The use of 2D/3D-HyFoSy, especially 2D/3D-HDF-HyFoSy, which had a significantly higher PPV (48% and 71%, P < 0.05 and P < 0.01; respectively), resulted in fewer false positive and inconclusive findings than the use of 2D-air/saline-HyCoSy. The LR- and LR+ was 0.14 and 14.8, respectively, for 2D/3D-HyFoSy, 0.06 and 32.1, respectively, for 2D/3D-HDF-HyFoSy, and 0.08 and 6.9, respectively, for 2D-air/saline-HyCoSy. The number of inconclusive or positive results per patient was significantly fewer with 2D/3D-HyFoSy (odds ratio, OR = 0.5, CI = 0.3-0.95, P < 0.05) and 2D/3D-HDF-HyFoSy (OR = 0.4, 95% CI = 0.2-0.8, P < 0.01) than with 2D-air/saline-HyCoSy. Limitations, reasons for caution An unselected infertile population with a low prevalence of tubal occlusion is suitable for estimating the diagnostic accuracy of imaging tests only as a screening tool. Wider implications of the findings These findings can be used to establish a diagnostic strategy with high accuracy but minimum invasiveness and limited use of contrast agents and sophisticated technology. 2D-Air/saline-HyCoSy, which has a high NPV, is suitable as an initial test and basic screening method, but 2D/3D-HDF-HyFoSy, which has a significantly higher PPV, can be used as a standard to verify any questionable or positive results obtained with 2D HyCoSy. This strategy may signficantly reduce the need for laparoscopy as a reference standard. Study funding/competing interest(s) There was no external funding for this study, and the authors have no conflicts of interest to declare. Trial registration number N/A.

Objectives:To compare two first-trimester screening strategies: traditional combined screening and the one based on ultrasound markers only. We investigated the effect of maternal age (MA) on the screening performance of both of these strategies.Methods:This was a prospective observational study based on a non-selected mixed-risk population of 11,653 women referred for first-trimester screening. The study population was divided in two groups: combined screening (CS) and ultrasound-based screening (US). Absolute risk was calculated to determine the influence of MA on screening performance.Results:The CS arm comprised 5145 subjects including 51 cases of trisomy 21 (T21), and the US arm comprised 5733 subjects including 87 subjects with T21. Seven hundred and seventy-five subjects were excluded from the study. For a false positive rate (FPR) of 3%, the detection rate (DR) of T21 in CS arm was 78% vs. 90% in US arm. For 5% FPR, DR was 84% and 94% in CS and US arm, respectively. MA had an influence on DR positive rates in CS: both DR and FPR for T21 increased with advance in MA.Conclusions:The US protocol showed higher DR of T21 compared to the CS one. It may be considered as a viable alternative to CS for T21 where access to biochemical testing is limited.

To investigate the incidence and outcome of antenatally diagnosed isolated transverse limb defects at a major tertiary center and to review the literature relevant to this rare condition. Methods.: This was a retrospective review of all cases (2000-2009) diagnosed with an isolated transverse limb defect referred to a tertiary fetal medicine center. Isolated transverse limb defects were defined as partial or complete absence of a part of one or more limbs in the absence of other abnormalities. Results.: Nine cases were identified. The upper limbs were affected in seven cases. The median gestational age at diagnosis was 22+5 weeks (range 21-29 weeks). The defects ranged from absence of digits to the absence of three limbs in one case. Four women opted to have termination of pregnancy. Postnatal and postmortem examination confirmed the ultrasound findings. No obvious risk factors could be identified in the majority of cases. Conclusions.: Most cases of limb defects are believed to be secondary to a vascular insult occurring early in embryonic life. The reason for upper limb predominance remains unclear. Perinatal outcome in this series was poor with the majority of pregnancies terminated. Long-term functional outcome depends on the severity of the limb reduction defect.

Monochorionic pregnancies present unique challenges for selective fetal reduction, as vaso-occlusive procedures are required to ablate blood flow, usually in the umbilical cord, to achieve asystole in the selected fetus. We describe a case series of 35 monochorionic pregnancies (27 twins and eight triplets) undergoing selective fetal reduction using radiofrequency ablation. All procedures were performed under local anaesthesia. The procedure was technically successful in all cases. The live born rate was 88.6%. One (2.9%) woman miscarried within 2 weeks of the procedure, and two (5.7%) babies were stillborn. The median gestation at delivery was 36 weeks of gestation (range 24-41 weeks). There were no maternal complications. The median gestational age at procedure was 17 + 3 weeks (range from 12 + 5 to 27 + 4 weeks). All women had antenatal magnetic resonance imaging (MRI) post procedure. There were two (5.7%) cases of abnormal brain imaging. Our experience suggests that radiofrequency ablation is a safe and effective procedure for fetal reduction in complicated monochorionic pregnancies.

Early Fetal Echocardiography (EFE) is generally defined as a fetal cardiac scan performed until 16 weeks of gestation. Fetal indications for EFE in the first trimester are in strong connection with ultrasound findings during routine nuchal scan: early diagnosed extracardiac malformations, abnormal ductus venosus (DV) velocimetry, tricuspid valve regurgitation (TR), single umbilical artery and increased NT measurement as a major fetal factor. Essential components of EFE include: abdominal view (AbdV), four chamber view (4CV), three vessel view (3VV), origin and cross-over of the great arteries (GA), aortic arch (AoA), ductal arch (DA), superior and inferior venae cavae and at least 2 pulmonary veins. EFE has some limitations, which determine delayed diagnosis of some CHDs. Early fetal echocardiography is feasible and reasonable. It gives parents the opportunity to exclude approximately 60% of cardiac abnormalities and to reassure them of normal heart anatomy as early as possible.

Carbon monoxide poisoning is one of the most frequent types of poisoning caused by gases. Exposure of a pregnant woman to carbon monoxide is connected with transmission of this gas to her fetus what may cause oxygen deficiency, and further, the damage to its organs. The article describes a case of carbon monoxide poisoning of a 28-weeks pregnant woman who was treated in a hyperbaric chamber. Therapy was successful and the woman gave birth to a healthy, full term infant. In case of poisoning to a pregnant woman the above seems to be the most advantageous solution.

Altered flow in ductus venosus (DV) may be caused by the changes in preload or afterload. Its association with aneuploidy and congenital heart defects (CHDs) was widely described.The aim of this study was to examine the incidence of a reversed a-wave in DV flow (revDV) and the absence of DV (noDV), their coincidences with other markers of aneuploidy or fetal abnormalities in a mixed-risk population.The study group covered women who underwent an ultrasound scan between 11+0 and 13+6 weeks’ gestation.Singleton pregnancies with known pregnancy outcome and a crown-rump length of 45–84 mm.A total of 5811 cases, including 137 aneuploidies, met the inclusion criteria: 35 subjects of noDV, 189 of revDV and 5587 of normal DV flow. The incidence of noDV in euploidy was 0.47%, and in aneuploidy 5.8%. The incidence of revDV in euploidy was 2.46%, and in aneuploidy 35.7%. Among aneuploidy, the highest prevalence of noDV was found in monosomy 45X. revDV showed the highest prevalence in trisomy 18. Isolated noDV was only found in euploidy. Isolated revDV subjects were only observed in euploidy and trisomy 21. Any combination of revDV with additional markers showed high incidence in major trisomies. Extracardiac anatomy and abnormal cardiac findings showed a higher prevalence in noDV and revDV cases.The presence of noDV might be useful in suspicion of monosomy X among cases with increased nuchal translucency, as well as in differentiating them from other aneuploidies. The combinations of aneuploidy markers with revDV are strong indicators of aneuploidy. revDV alone is a poor screening tool for aneuploidy and euploidy with CHD.

Objective: To externally validate the International Ovarian Tumor Analysis (IOTA) Simple Rules (SR) by examiners with different levels of sonographic experience defined by the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) and to assess the morphological ultrasound features of the adnexal tumors classified as inconclusive based on IOTA SR. Materials and Methods: In the two-year prospective study adnexal tumors were assessed preoperatively with transvaginal ultrasound by examiners with different levels of experience (level 1- IOTA SR1, level 2-IOTA SR2). Additionally, an expert (level 3) evaluated all tumors by subjective assessment (SA). If the rules could not be applied, the tumors were considered inconclusive. The final diagnosis was based on the histopathological result of the removed mass. The diagnostic performance measures for the assessed model were sensitivity, specificity, negative (LR-) and positive(LR+) likelihood ratios, accuracy (ACC) and diagnostic odds ratio (DOR). Results: 226 women with adnexal tumors scheduled for surgery were included in the stutdy. The prevalence of malignancy was 36.3 % in the group of all studied tumors and was 52.5 % in the inconclusive group (n = 40) (p = 0.215). Fewer tumors were classified as inconclusive by level 2 examiners compared to level 1 examiners [20 (8.8 %) vs. 40 (17.7 %); p = 0.008], resulting from the discrepancy in the evaluation of acoustic shadows and the vascularization within the tumor. For level 1 examiners a diagnostic strategy using IOTA SR1 +MA (assuming malignancy when SR inconclusive) achieved a sensitivity, specificity and DOR of 96.3 %, 81.9 %, 13.624 respectively. For level 2 examiners the diagnostic strategy for IOTA SR2 +MA achieved a sensitivity, specificity and DOR of 95.1 %, 89.6 %, 137,143, respectively. Adding SA by an expert (or level 3 examiner) when IOTA SR were not applicable improved the specificity of the test and achieved a DOR of 505.137 (SR1 +SA) and 293.627 (SR2 +SA). The SA by an expert proved to have the best diagnostic performance with a DOR of 5768.857, and a sensitivity and specificity of 97.6 % and 99.3 % respectively. Within the inconclusive group the most common tumors were unilocular-solid (n-13), solid (n-8) and multilocular-solid (n–10) ones. All multilocular tumors were classified as inconclusive because of their size (≥ 100 mm) and were found to be benign by pathology. Most of the inconclusive tumors with cystic content presented low-level (43.75 %) echogenicity, followed by ground-glass (34.37 %), mixed (12.5 %) and anechoic (9.4 %). Conclusion: The study results show excellent diagnostic performance of IOTA Simple Rules followed by subjective expert assessment in inconclusive tumors irrespective of the level of experience, while subjective assessment by an expert still has the highest diagnostic odds ratio. The number of inconclusive cases seems to depend on the level of ultrasound expertise and less experienced examiners have a tendency to overestimate blood flow and a presence of acoustic shadows within the tumors. IOTA SR were not applicable either because no benign or malignant features were found or both were identified. Within inconclusive tumors the majority of cases comprise malignant masses that are either unilocular-solid, solid tumors or small multilocular-solid ones with a diameter of less than 100 mm.

Trisomy 18 (T18) remains the second most common aneuploidy. It is associated with multiple congenital anomalies and causes intrauterine fetal demise in the most severe cases.To examine the screening performance of ultrasound-based protocols for detecting T18, we aimed to determine the most common signs and their prevalence in fetuses with T18 to develop logistic regression model.This was a prospective study based on singleton pregnancies examined at gestation 11+0 to 13+6. The referrals constituted 6210 patients. Scan protocol enclosed a systematic review of the entire early fetal anatomy, including fetal cardiac evaluation and sonographic signs of aneuploidy.Our study population comprised 5650 pregnancies: 5613 cases with a normal karyotype and 37 cases with T18. The mean nuchal translucency (NT) thickness in the subgroup of euploidy was 1.7 and in the subgroup of T18 it was 5.4. No statistically significant differences were found in terms of maternal age. One case of T18 (2.7%) demonstrated no markers of aneuploidy as opposed to 5111 cases of euploidy (91.1%). Extracardiac malformations were identified in 13 cases of T18 (35.1%) and in 48 cases of euploidy (0.8%). Congenital heart defects were observed in 26 cases of T18 (70.3%) and in 27 cases of euploidy (0.5%).Our results showed good screening performance of ultrasound-based risk calculation models. When the first trimester pattern of T18 is considered, an increased NT, tricuspid regurgitation, single umbilical artery, omphalocele and right dominant heart should be specifically searched for.

Background Tricuspid regurgitation (TR) is a common sonographic finding during the fetal life. It has been reported in 7% of normal fetuses. It may be associated with aneuploidy and with both cardiac and extracardiac defects. Objectives In this study, we have looked at the characteristics of fetuses with and without TR at 11+0 to 13+6 weeks' gestation. Groups were compared with respect to the following variables: prevalence of chromosomal defects; other markers of aneuploidy; fetal cardiac; and extracardiac anomalies. Methods The study group included women, who underwent an ultrasound examination at 11-13+6 weeks' gestation between 2009 and 2012. The inclusion criteria were singleton pregnancies with crown-rump length measurements of 45-84 mm where the pregnancy outcome was known. Results Some 1075 patients met our inclusion criteria including 979 fetuses without TR and 96 with TR. There were 72 cases of aneuploidy diagnosed (6.7%). Isolated TR was found in 53 euploid fetuses (5.2%). All of the TR(+) aneuploid fetuses (n=40) had additional ultrasound markers present. Extracardiac anatomy showed a higher prevalence of abnormalities in the group of TR positives (12.5%) vs. TR negatives (1.6%). Abnormal cardiac findings were more frequent in the TR-positive group independently of chromosomal status and were found in 18.8% of fetuses with TR and in 1.9% with a normal tricuspid flow. Conclusions TR in combination with other markers is the strongest predictor for aneuploidy. TR, as an isolated parameter, is a poor screening tool both for all and for each individual chromosomal abnormality and congenital cardiac defects.

Objectives The first goal of this study was to analyze the diagnostic performance of the 4-chamber view, 3-vessel and trachea view, and their combination in color mapping during early cardiac evaluations for selecting cases suspicious of congenital heart defects. The second goal was to describe the most common abnormal flow patterns at the levels of the 4-chamber and 3-vessel and trachea views in the late first trimester. Methods We conducted a prospective observational study in which a simple cardiac sonographic protocol was applied in fetuses at gestational ages of 11 weeks to 13 weeks 6 days. Results A total of 1084 patients with known postnatal or autopsy findings were included in the study. The median maternal age was 32.3 years (range, 27-40 years). The median crown-rump length was 62.2 mm (range, 45-84 mm). Overall, there were 35 cases with a confirmed congenital heart defect (3.22%), including 16 accompanied by aneuploidy. We found that our simple first-trimester cardiac protocol was an effective screening method for congenital heart defects. The most effective approach of the 3 evaluated by us was the combined application of the 4-chamber and 3-vessel and trachea views in color mapping compared to the 4-chamber and 3-vessel and trachea views alone. We defined the most common ventricular inflow patterns and the V sign. The technique we used was simple and easy to reproduce. Conclusions We confirmed that evaluation by two basic cardiac views allows for selection of most cases with a univentricular heart, atrioventricular septal defects, coarctation of the aorta, pulmonary stenosis, pulmonary atresia, and conotruncal defects.

Objective: In this paper we describe the technique of first-trimester cardiac evaluation that is used routinely for all nuchal scans at our institution and explain the pattern recognition concept. Early cardiac assessment is generally performed at the time of first trimester nuchal scan. At this time of gestation, the cardiac structures are already developed and their mutual geometry is fixed as it is observed in the second trimester. Information acquired during the scan should let the examiner answer the following questions: Is the fetal heart located in the normal expected position? Is the visceral situs normal? Are the two ventricles developed? Is there a normal arrangement between both arches? Are these arches balanced in size?

The aging of the women population as well as widespread use of the ultrasound leads to an increased detection of abnormal endometrial characteristics. The aim of this study was to assess the value of three-dimensional ultrasound viewing options: multi-planar view (MPV) and volume contrast imaging (VCI) in the endometrial evaluation. 147 women, referred for endometrial sampling, because of bleeding or an abnormal endometrial two-dimensional ultrasound image were enrolled in the study. Before dilation and curettage, all patients underwent three-dimension ultrasound scans for endometrial thickness measurements and endometrial-myometrial junction assessment. Ultrasound results and the presence of abnormal vaginal bleeding were compared with pathological diagnosis. Sensitivity, specificity, negative predictive value, and positive predictive value for abnormal vaginal bleeding, irregular endometrial-myometrial junction and endometrial thickness were established. Logistic regression model was used to assessed the relationship between the characteristics and the incidence of endometrial pathology. For each of the independent variables odds ratios were calculated. Sensitivity, specificity of the endometrial thickness cut-off 11 mm were 73.8%, 74.4%, for 10.5 mm 76.2%, 69.8% respectively. The irregular endometrial-myometrial junction reached 70.5% sensitivity and 93% specificity. Odds ratios for 10,5 mm cu-off value of the endometrial thickening and irregular E-M junction were calculated: 4.10 [95% CI: 1.14-14.74] and 36.07 [95% CI: 7.10-183.27]. The negative predictive value of any of these parameters did not exceed 70%. The combination of 3D ultrasound parameters and the occurrence of abnormal vaginal bleeding has reached only 53% sensitivity. In the case of connection of two of these three indices, increased sensitivity of 76.9% and specificity of 82.4%. In an unselected group of women in terms of menopausal status and symptoms endometrial thickness measured and the evaluation of endometrial-myometrial junction using 3D ultrasound is less value in predicting the occurrence of endometrial cancer than in 2D and the endometrial volume calculation.

To predict the 1-step complete resection rate after transrectal ultrasound-guided hysteroscopic myomectomy and to determine the usefulness of intraoperative transrectal ultrasonography (TRUS) in monitoring hysteroscopic electroresection of submucosal myomas.Prospective cohort study (Canadian Task Force classification II-1).University hospital.One hundred twenty women with symptomatic (abnormal uterine bleeding or reproductive disorder), single, submucosal myomas underwent hysteroscopic electroresection. Groups 1 and 2 were monitored, respectively, with or without TRUS. Anatomical inclusion criteria were myoma ≤5 cm and myometrial free margin ≥3 mm above the myoma.Myomas were evaluated preoperatively via sonohysterograpy and were graded according to the guidelines outlined by the European Society of Hysteroscopy (ESH), including size and myometrial free margin, and according to the STEPW (size, topography, extension, penetration, and lateral wall) classification. On the basis of sonographic findings, patients with myomas3 cm received gonadotropin-releasing hormone therapy for 1 to 3 months. Hysteroscopic myomectomy was performed with or without TRUS guidance. At 4 to 8 weeks after the initial procedure, postoperative transvaginal ultrasonography, sonohysterography, or second-look hysteroscopy was performed.In the TRUS group, a significantly higher percentage of 1-step complete resections was observed than in the group without TRUS (91% vs 73%) (p = .02). This was associated with a statistically significant difference in the subgroups of myomas that were deeply penetrating into the myometrium (89% vs 55%) (p.01). One-way logistic analysis of data for all treated patients indicated the use of TRUS, as well as the ESH and STEPW classifications, as significant factors influencing the 1-step complete resection. At multivariable logistic regression analysis, use of TRUS (odds ratio [OR], 2.74; p.001), myomas graded 0 or 1 according to ESH (OR, 3.55; p.001), and size3 cm (OR, 2.35; p.05) were significantly associated with 1-step complete resection (area under the curve, 0.80; p.001). In the TRUS group there were two significant predictors: size3 cm (OR = 5.21; p.05) and myometrial free margin5 mm (OR, 0.18; p.05).Intraoperative use of TRUS during hysteroscopic myomectomy increases the chance of complete 1-step removal of submucosal myomas that deeply penetrate the myometrium.

Technological advances in the construction of sonographic devices and increasingly universal access to such tests considerably widens the range of diagnostic application of the sonographic examination. This situation also refers to pelvic organs prolapse. At present, sonographic sets used in everyday obstetrical-gynecological practice allow for insight into the structures forming the female pelvic floor, and the obtained images constitute a valuable addition to the physical examination. Positioning the sonographic transducer on a the perineum enables to visualize the three compartments of the female pelvis minor. After freezing the image, it is possible to assess the position of anatomical structures in relation to bones and designated surfaces, establish mutual distances and measure appropriate angles. Most information can be obtained in this manner within the range of the frontal compartment, whose damage is often linked with urinary incontinence. The examination standards developed so far, including the analysis of the quantitative parameters, greatly minimize the potential subjectivity of the assessment of the existing disorders. Apart from its low costs, the main value of the sonographic examination of the pelvic floor is the possibility to dynamically assess the changes in statics which take place during functional testing. Not only does it have a cognitive significance, but also it allows to adjust the scope of the surgical correction to the existing damages. Thus, indirectly it can contribute to the reduction of a number of subsequent remedial surgeries. Three-dimensional sonography allows to thoroughly examine the construction and functioning of the anal levators and to detect their possible damage. It is the trauma to these muscles--occurring, among others, during childbirth--that is one of the major causes of pelvic organs descent and prolapse in women. Sonographic examination also enables to visualize the artificial material, the use of which is increasingly frequent in the surgical treatment of pelvic organs prolapse. The remedial kits currently in use are not visible in classic X-ray examinations and CT however, they can be easily visualized by means of a sonographic test. This way it is possible to locate the positioned tapes or meshes and to establish their orientation towards the urethra, the bladder and the anus. It is also possible to observe the complications (e.g. hematomas) following the surgical procedures via the transvaginal access. Transperineal sonography is a relatively inexpensive method that may be performed in almost every ultrasonographic laboratory Its value, approaching the MRI diagnostic value in the assessment of the pelvic floor defects and its low cost, place ultrasonography on the first place among the methods of imaging the pelvic and uro-genital diaphragm. The results of diagnostics of pelvic organs prolapse obtained by placing the sonographic head on the patient's perineum may also help in establishing the changes of the support apparatus for the uterus and the vagina, bladder urethra and perineum during functional testing and, thus, to verify the clinically established degree of the prolapse. It seems, also, that this method may be used during peri-urethral injections of specific substances and post-application follow-up, an increasingly frequently employed method of urinary incontinence treatment.

Premenstrual syndrome (PMS) affects 3-5% of women. It still remains controversial in diagnosis and treatment. Dynamic progress in neuroendocrinology in recent years led to PMS etiology explanation. It also influenced therapeutic approach. According to Wang et al. neuroactive steroids and their imbalance evoke PMS symptoms. That theory introduced other therapeutic interventions restoring neuroendorine balance. The newer antidepresants demonstrated excellent efficacy in treatment of somatic and emotional PMS symptoms. PMS is a typical object of contemporary studies on therapeutic efficacy according to evidence based medicine.

Advance in medicine in general caused more and more women with cardiac defects reach reproductive age.Analysis of kind and advance of cardiac disease influence on preterm labour and IUGR rates.A prospective study on 232 pregnant patients with cardiac malformations, who were hospitalised in Pathology of Pregnancy Unit of OB./ GYN Jagiellonian University Clinic was performed between 1986-1999. Acquired data were compared with results obtained from control group of 424 pregnant patients with physiological course of pregnancy.Results prove of shorter pregnancy duration in patients with higher NYHA classes. Preterm labour rate in patients of NYHA III and IV equals to 31.15% and is 3 times higher than in control group. Patients of NYHA I and II revealed comparable gestational age with control group.Worse obstetric outcome is characteristic for 3rd and 4th NYHA classes. Intrauterine growth retardation in patients with cardiac malformations occurs after 34 week of pregnancy.

The coexistence of Non Hodgkin Lymphoma and pregnancy has been rarely reported. We are describing the case of 26-year-old pregnant woman, to whom two chemotherapy courses were administered because of the lymphoma. In 32 week of pregnancy cesarean section was performed due to patient general state worsening. Despite of chemotherapy children have been developing well. In the course of treatment autologous STEM cell transplant was performed. Since 13 months patient has been in remission.

Physiological maternal changes during pregnancy and cardiac disease symptoms are described. Prediction of good fetal outcome and delivery in the pregnant patient suffering from cardiac disease requires accurate assessment of cardiac disease advancement, its type and severity, frequent follow-up and immediate intervention in any case of worsening. Concerning chances and risks further influence of pregnancy and delivery on cardiac disease in the mother should be included.

Apart from increasing frequency of ectopic pregnancy occurrence during recent years there is still a need to diagnose and treat these pathology as early as possible. Delay in diagnosing subsequently cause severe threat to patients life. Recognition improvement means equally decrease in mortality connected to ectopic pregnancy.The aim of the study was diagnosis and treatment efficiency evaluation in cases of ectopic pregnancy.In this paper 68 cases of women hospitalised between May 1999 and September 2002 in our Clinic with suspicion of ectopic pregnancy were analysed. Diagnostic procedures included clinical examination, biochemical assessment of beta HCG level, sonography and diagnostic laparoscopy. Therapeutic management included salpingotomy with evacuation of gestational sac, salpingectomy and uterine cornu excision.In 11 cases the presence of pregnancy was excluded according to non-invasive diagnostics. Laparotomy was performed in two cases. Laparoscopy was performed in 50 cases what equals to 73% of all subjects. Laparoscopy was negative in 7 cases. Misdiagnosis resulted from pathologies in adnexal area. The most frequent ectopic pregnancy localisation was oviduct, one case of cervical and one intramural localisation was diagnosed. In one case two salpingostomies were performed in two years apart period.Complex diagnostic management is the only diagnostic way in case of ectopic pregnancy. Any confusion should be solved by immediate invasive diagnostics. In our opinion the most efficient method in ectopic pregnancy diagnosing and treatment is early laparoscopy.

Utility of laparoscopic procedures in pregnant women. Is laparoscopy safe for the foetus?Between 1996 an 2002 14 pregnant patients were admitted and laparoscopy was performed.In 10 cases laparoscopic cyst enucleation (6 simplex, 1 endometrial, 3 dermoidal), in 1 case myomectomy and in 2 adnexectomy was performed. There were no complications during surgery. In one case miscarriage occurred 3 weeks after laparoscopic surgery and 9 healthy babies were delivered.There is no doubt that laparoscopy is well accepted in gynecological surgery and is going to be more and more accepted in obstetrics. Due to several differences between non-pregnant and pregnant women laparoscopic procedures in pregnancy require special attention. All papers show good foetal outcome even with preterm labour. In our material all babies were born healthy.Laparoscopic procedures during pregnancy are feasible and safe. Nevertheless they have to be performed by experienced gynecological-surgical teams.
