Prenatal cerebellar growth is altered in congenital diaphragmatic hernia on ultrasound.

OBJECTIVE: Children with congenital diaphragmatic hernia (CDH) are at risk for neurodevelopmental delay. Herein we report on prenatal changes in biometry and brain perfusion in fetuses with isolated CDH. STUDY DESIGN: This retrospective study evaluated fetuses with isolated, left-sided CDH in three European referral centers. Abdominal circumference (AC), femur length (FL), head circumference (HC), transcerebellar diameter (TCD), middle cerebral artery (MCA) Doppler, and ventricular width (VW) were assessed during four gestational periods (<24 weeks, 25-28 weeks, 29-32 weeks, >33 weeks). Z-scores were calculated, and growth curves were created based on longitudinal data. RESULTS: In 367 fetuses, HC, AC and FL were within normal ranges throughout gestation. The TCD diminished with advancing gestational age to fall below the fifth percentile after 32 weeks. A less pronounced but similar trend was seen in VW. The peak systolic velocity of the MCA was consistently approximately 10% lower than normal. Disease severity was correlated to TCD (p = 0.002) and MCA doppler values (p = 0.002). There were no differences between fetuses treated with FETO and those managed expectantly. CONCLUSION: Fetuses with isolated left-sided CDH have a small cerebellum and reduced MCA peak systolic velocity. Follow up studies are necessary to determine the impact of these changes on neurodevelopment.

Percutaneous Intratumor Laser Ablation for Fetal Sacrococcygeal Teratoma.

OBJECTIVE: To evaluate the efficiency of percutaneous intratumor laser ablation for fetal solid sacrococcygeal teratoma (SCT). SUBJECTS AND METHODS: We carried out percutaneous ultrasound-guided intratumor laser ablation through a 17-gauge needle using an output of 40 W in 7 fetuses with large solid SCT and reviewed the literature for minimally invasive therapy for this condition. RESULTS: Laser ablation was carried out at a median gestational age of 20 (range 19-23) weeks, and in all cases there was elimination of obvious vascularization within the tumor and improvement in cardiac function. Three (43%) babies survived and had surgical excision of the tumor within 2 days of birth, 3 liveborn babies died within 5 days of birth and before surgery, and 1 fetus died within 2 weeks after the procedure. In previous series of various percutaneous interventions for predominantly solid SCT the survival rate was 33% (2/6) (95% CI 9.7-70%) for endoscopic laser to superficial vessels, 57% (4/7) (95% CI 25-84%) for intratumor laser, 67% (8/12) (95% CI 39-86%) for intratumor radiofrequency ablation, and 20% (1/5) (95% CI 3.6-62%) for intratumor injection of alcohol. CONCLUSIONS: In solid SCT, the reported survival from intratumor laser or radiofrequency ablation is about 50%, but survival does not mean success, and it remains uncertain whether such interventions are beneficial or not because the number of fetuses is small and there were no controls that were managed expectantly.

Ventriculo-amniotic shunting for severe fetal ventriculomegaly.

INTRODUCTION: Severe fetal cerebral ventriculomegaly, observed in about 1 in 1000 newborns, is associated with a high risk of perinatal death and neurodevelopmental delay in survivors. The objective of this study was to evaluate the efficiency of ventriculo-amniotic shunting for drainage of severe fetal cerebral ventriculomegaly and the neurodevelopment of survivors at the age of 2 years. MATERIAL AND METHODS: This was a retrospective study of 44 fetuses with severe bilateral ventriculomegaly treated with ventriculo-amniotic shunting in a tertiary fetal therapy center between 2010 and 2015. RESULTS: Shunt insertion was successfully carried out at a median gestational age of 25 weeks (range 20-33 weeks). There were three fetal deaths within 24 hours of the procedure and 41 live births at a median gestational age of 37 weeks (range 28-39 weeks). Neurodevelopment at 2 years of age was evaluated using the Bayley scale in the 38 survivors. In the 27 cases with isolated ventriculomegaly 19 (70.4%; 95% confidence interval [95% CI] 51.5%-84.2%) had normal or mild neurodevelopmental delay and 8 (29.6%; 95% CI 15.6%-48.5%) were moderately or severely delayed. In the 11 with non-isolated ventriculomegaly 2 (18.2%; 95% CI 5.1%-4.8%) had normal or mild neurodevelopmental delay and 9 (81.8%; 95% CI 52.3%-94.9%) babies were moderately or severely delayed. CONCLUSIONS: Ventriculo-amniotic shunting is an option for the management of severe ventriculomegaly and results in normalization of the ventricular diameter. However, a high proportion of survivors have neurodevelopmental delay and the possible beneficial effect of ventriculo-amniotic shunting needs to be assessed by randomized studies.

Thoracoamniotic Shunts in Macrocystic Lung Lesions: Case Series and Review of the Literature.

OBJECTIVE: To evaluate the efficiency of thoracoamniotic shunts for drainage of macrocystic-type congenital cystic adenomatoid malformation (CCAM). SUBJECTS AND METHODS: This was a retrospective study of 12 fetuses with a large thoracic cyst treated with thoracoamniotic shunting between 2004 and 2014 in a tertiary fetal therapy center. Medline was searched to identify cases of CCAM treated with thoracoamniotic shunting. RESULTS: In all cases the thoracic cyst was associated with major mediastinal shift, the CCAM volume ratio (CVR) was >1.6, and in eight cases there was associated hydrops. Shunt insertion was successfully carried out in all cases at a median gestational age of 24 weeks (range 18-34). In 10 cases there was live birth at a median age of 38 weeks (range 35-41), but in two hydropic fetuses there was intrauterine death. A literature search identified a total of 98 fetuses with CCAM treated with thoracoamniotic shunting between 1987 and 2016. In the combined data from the previous and the current study, the survival rate was 77% (53 of 69) for hydropic and 90% (37 of 41) for nonhydropic fetuses. CONCLUSIONS: The role of thoracoamniotic shunting in macrocystic lung lesions associated with hydrops is well accepted. Intrauterine intervention is also likely to be beneficial in the subgroup of nonhydropic fetuses with a CVR >1.6.

Maternal and fetal parameters including umbilical artery PI and fibrinogen/CRP ratio as predictive factors of perinatal outcome in women with HELLP syndrome.

INTRODUCTION: HELLP syndrome appears in approximately 0.2-1% of all pregnancies and is associated with in- creased maternal and fetal mortality and morbidity. It is diagnosed in cases when all three of the following criteria are present: (1) microangiopathic hemolytic anemia with abnormal blood smear low serum haptoglobin and elevated LDH levels; (2) elevated ASPATand ALAT (levels of both enzymes more than twice the upper limit of normal values), or bilirubin more than 1.2 mg/dl; 3) platelet count below 150x1009 L(-1). The etiopathogenesis of HELLP syndrome is associated with abnormal placentation in the first trimester production of cellular active substances, and pathological response of the maternal organism. Objectives: The aim of the study was to establish maternal and fetal characteristics and perinatal outcome in HELLP syndrome. The examination protocol included comparison of maternal blood parameters, umbilical artery pulsatility index (UmbA PI) in relation to short-term neonatal outcomes. MATERIAL AND METHODS: Retrospective data analysis of patients hospitalized at the Perinatology and Gynecology Department, Polish Mother's Memorial Hospital Research Institute between 2009-2013, due to HELLP syndrome was conducted. RESULTS: None of the investigated maternal or fetal parameters correlated with the neonatal outcome. CONCLUSIONS: Our study demonstrated that maternal parameters do not influence the perinatal outcome in women with HELLP syndrome. Moreover UmbA PI and fibrinogen/CRP ratio do not correspond to neonatal parameters, either Thus, none of the examined features can be used as a prognostic factor of the neonatal outcome. Further studies with large sample size are necessary but the rarity of this complication limits the possibility of research.

Biochemical markers in screening for preeclampsia and intrauterine growth restriction.

OBJECTIVES: The aim of the study was to evaluate the relationship between the concentrations of substances released by the placenta: placental growth factor (PIGF), pregnancy-associated plasma protein A (PAPP-A) and free beta-human chorionic gonadotropin (beta-hCG) and the risk of early and late preeclampsia (PE) and intrauterine fetal growth restriction (IUGR). MATERIAL AND METHODS: A total of 180 pregnant women between 11+0 and 13+6 weeks gestation were recruited for a case-control study Twenty-two patients suffered from early PE, 29 patients from late PE. Data analyzed during the study included maternal histoty and concentrations of PAPP-A, PlGF beta-hCG. RESULTS: The multiple of the median (MoM) value of the PAPP-A concentrations was 1.01 in the control group (interquartile range (1QR), 0.65-1.55), 0.67 (1QR, 0.382-0.82) in the group of patients with early preeclampsia and 0.74 (IQ, 0.33-1.09) in the group of patients suffering from late preeclampsia. MoM value of the PIGF concentrations was 1.21 in the control group (IQR, 0.93-1.57), 0.62 (IQR, 0.51-0.96) in the group of patients with early preeclampsia and 0.92 (lQR, 0.63-1.09) in the group of patients suffering from late preeclampsia. MoM value of beta-hCG concentrations was 1.14 in the control group (IQR, 0.75-1.49), 1.08(IQR, 0.74-1.23) in the group of patients with early preeclampsia and 1,25(IQR, 1,05-1,49) in the group of patients suffering from late preeclampsia. The performance of screening was determined by the areas under the curve and detection rates, with a fixed false-positive rate of 10%. CONCLUSIONS: Decreased levels of PAPP-A and PIGF are related to an increased risk of preeclampsia and its complications.

[Fetal therapy--evaluation of intrauterine therapy in congenital cystic adenomatoid malformation of the lung (CCAM)]. / Terapia plodu--ocena skutecznosci leczenia wewnatrzmacicznego wrodzonego zwyrodnienia gruczolakowato-torbielowatego pluc (CCAM).

OBJECTIVES: The aim of the study was to evaluate the efficiency of intrauterine treatment of large cysts in fetal lungs using thoracoamniotic shunts. MATERIAL AND METHODS: Our observational retrospective study was carried out on a series of 8 fetuses who under went thoracoamniotic shunting after sonographic statement of large macrocystic lesions in the lungs at the Department of Gynecology Fertility and Therapy of the Fetus, Polish Mother's Research Institute, between 2009-2014. RESULTS: Mean gestational age at shunt insertion was 26.6 (range 18-33) weeks. Marked mediastinal shift in the echocardiographic examination was observed in all of the investigated cases. Five fetuses had polyhydramion, with 4 hydropic cases. Out of the remaining 4 fetuses without impaired cardiac function, 3 had very large lesions at initial presentation and 1 had a lesion that was rapidly increasing in size. Shunt insertion was successful in all cases. Only one patient went into premature labor (at 36 weeks of gestation). Mean gestational age at delivery was 38.2 weeks. Cesarean section was necessary in the half of the patients due to obstetric complications. All newborns underwent resection of the lesions. Three of them were operated in the first month after birth. The rest of the operations were postponed. Prenatal diagnosis of congenital cystic adenomatoid malformations was confirmed by pathologists in all cases. CONCLUSION: Intrauterine therapy of macrocystic lesions in fetal lungs enables to achieve good perinatal outcome It needs to be considered in every case of a fetus with developing impaired cardiac function.

The use of panniculectomy in morbidly obese patients undergoing gynecological surgery.

Panniculectomy is a surgical procedure that involves removal of the skin and fat excess which facilitates access to the peritoneal cavity. In the paper we present three cases of morbidly obese women (BMI: 46.3-59.5) who were treated in the Department of Gynecology and Oncological Gynecology in Lodz. One of the patients underwent an operation due to the presence of a large cervical myoma. Two another women were treated for endometrial cancer. During all of the three procedures panniculectomy was the first stage of the operation.

The role of angiogenic factors in endometrial cancer.

Endometrial cancer is the most common malignancy within the female reproductive system (37.7%). The incidence increases with age. Frequently this type of cancer is diagnosed in peri- and post-menopausal women. 60-70% of cancers occur in women over 60 years of age, and less than 5% in women below 40 years of age. Angiogenesis is a process of formation of new microvessels from existing capillaries. There are four different mechanisms of new vessel growth: sprouting, intussusception, vessel elongation and incorporation of endothelial progenitor cells into new microvessels. Angiogenesis plays important roles in growth of endometrial cancers. This process is controlled by many angiogenic factors, for example vascular endothelial growth factor (VEGF). VEGF is the most powerful and most specific endothelial cell growth factor. It plays a crucial role in the initiation of physiological and pathological angiogenesis, lymphangiogenesis, and vasculogenesis. The VEGF family consists of VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGF-E, VEGF-F and PLGF (placental growth factor). The effects of VEGF are mediated through binding to the two specific and homologous receptors VEGFR-1 (FLT-1) and VEGFR-2 (KDR). Placental growth factor (PLGF) belongs to the VEGF family and it is also a very important growth factor. So far four isoforms of PLGF have been identified: PLGF-1 (PLGF131), PLGF-2 (PLGF152), PLGF-3 (PLGF203) and PLGF-4 (PLGF224).

Vaginal hysterectomy vs. laparoscopically assisted vaginal hysterectomy in women with symptomatic uterine leiomyomas: a retrospective study.

INTRODUCTION: Uterine leiomyomas are the most common benign tumors of the female reproductive system. Although the majority of myomas are asymptomatic, some patients have symptoms or signs of varying degrees and require a hysterectomy. THE AIM OF THE STUDY: The aim of the study was to compare the clinical results of two minimally invasive hysterectomy techniques: vaginal hysterectomy (VH) and laparoscopically assisted vaginal hysterectomy (LAVH). MATERIAL AND METHODS: A retrospective, observational study was performed at a tertiary care center: the Gynecology and Gynecologic Oncology Department, Polish Mother's Memorial Hospital Research Institute. The study period was from January 2003 to December 2012. A total of 159 women underwent either vaginal hysterectomy (VH, n = 120) or laparoscopically assisted vaginal hysterectomy (LAVH, n = 39) for symptomatic uterine myomas. Outcome measures, including past medical history, blood loss, major complications, operating time and discharge time were assessed and compared between the studied groups. Statistical analysis was performed using Student t-test, U-Mann Whitney test, χ(2) test and Yates'χ(2) test. P < 0.05 was considered statistically significant. RESULTS: There were no differences in patients' mean age. Parity was significantly higher in the VH group (VH 1.9 ± 0.7 vs. LAVH 1.5 ± 0.8; p = 0.008). No difference was found in the mean ± standard deviation (SD) uterine volume between vaginal hysterectomy and LAVH groups (179 ± 89 vs. 199 ± 88 cm(3)), respectively. The mean operative time was significantly longer for the LAVH group (83 ± 29 vs. 131 ± 30 min; p = 0.0001). The intraoperative blood loss (VH 1.3 ± 1.1 vs. LAVH 1.4 ± 0.9 g/dl; p = 0.2) and the rate of intra- and postoperative complications were similar in both groups studied. The mean discharge time was longer for LAVH than for VH (VH 4.2 ± 1.2 vs. LAVH 5.3 ± 1.3 days, p = 0.0001). CONCLUSIONS: Laparoscopically assisted vaginal hysterectomy and VH are safe hysterectomy techniques for women with the myomatous uterus. Concerning the LAVH, the abdominal-pelvic exploration and the ability to perform adnexectomy safely represent the major advantages comparing with VH. Vaginal hysterectomy had a shorter operating time and the mild blood loss making it a suitable method of hysterectomy for cases in which the shortest duration of surgery and anesthesia is preferable.

[Salpingotomy vs salpingectomy--a comparison of women's fertility after surgical treatment of tubal ectopic pregnancy during a 24-month follow-up study]. / Salpingotomia vs salpingektomia--porównanie plodnosci kobiet po operacyjnym leczeniu jajowodowej ciazy ektopowej, 24-miesieczne badanie obserwacyjne.

INTRODUCTION: Ectopic pregnancy (EP) is usually located in the Fallopian tube and it has a significant adverse effect on womens fertility Three types of EP treatment include: expectant, medical, and surgical radical (salpingectomy) or conservative (salpingotomy) management. OBJECTIVES: The aim of the study was to compare women's fertility after surgical radical or conservative treatment of tubal ectopic pregnancy MATERIALS AND METHODS: Out of the 58 patients operated because of tubal EP pregnancy 22 underwent laparoscopic salpingotomy (group 1) and 36 laparoscopic salpingectomy (group 2). EP-related data were obtained from medical documentation (the symptoms, diagnostic tests, EP risk factors, medical reproductive and surgical history clinical status during EP surgery). Follow-up data were collected by means of a telephone interview. The survey included questions focused on women's fertility during a 24-month period following the surgical treatment of EP (conception, subsequent intrauterine pregnancies and ectopic pregnancy). RESULTS: A 24-month follow-up period revealed that the cumulative intrauterine pregnancy rate was higher in group 1 (salpingotomy) as compared to group 2 (salpingectomy), i.e. 50% vs. 41.5%, respectively. Tubal EP returned in 13.6% cases (group 1) vs. 19.4% (group 2). All submitted results are statistically insignificant. CONCLUSIONS: Our findings are consistent with the literature which reports a trend of higher odds for intrauterine pregnancy after salpingotomy for surgical treatment of EP as compared to salpingectomy Moreover the risk for recurrent tubal EP is comparable for both methods. Regardless, the decision about the operating range in case of EP always depends on the actual clinical state of the patient.

Outcome of Monochorionic Diamniotic Twins with Twin Reversed Arterial Perfusion Sequence: Interstitial Laser versus Endoscopic Cord Occlusion.

Twin reversed arterial perfusion sequence (TRAP) is a rare complication of monochorionic twins (MC). This study aimed to describe and compare the short- and long-term outcomes of MC pregnancies with the TRAP sequence treated with two different techniques: interstitial fetal laser (IFL) (n = 22) versus endoscopic cord occlusion (CO) (n = 24). The study population included 46 MC pregnancies with TRAP. Pregnancy loss within 2 weeks after the procedure occurred in 27% of cases (6/22) in the group treated with IFL and in 8% of cases (2/24) in the group treated with CO. The survival rate of the pump twin was 73% (16/22) in the IFL group and 83% (20/24) in the group treated with CO. The median gestational age at birth was 38 weeks in the group treated with IFL and 35 weeks in the group treated with CO. The rate of preterm birth before 34 weeks was 12.5% (2/16) in the group treated with IFL and 32% (7/22) in the group treated with CO. In the group treated with IFL, there were no cases of neurological disabilities reported by the parents compared to three cases in the CO group. IFL is associated with a higher risk of early pregnancy loss; however, if the pregnancy progresses, it is associated with lower risks of preterm birth and neurological disabilities in the survivors.

Amniocentesis in Twin Pregnancies: Risk Factors of Fetal Loss.

This study aims to determine if second trimester amniocentesis in twin pregnancies provides a significant independent contribution in the prediction of miscarriage or fetal loss at any stage of pregnancy. This was a retrospective cohort study of women with twin gestations booked for routine prenatal care in four fetal medicine units in Poland in the years 2010-2020. The study population included: (1) twin pregnancies that underwent amniocentesis at 16-20 weeks' gestation; (2) twin pregnancies that did not require any further testing and were followed-up routinely. Univariable and multivariable regression analysis was used to define which maternal and pregnancy characteristics provided a significant independent contribution in the prediction of miscarriage and fetal loss at any stage of pregnancy. In the study period, 2645 twin pregnancies were eligible for analysis. There were 144 cases of miscarriage defined as fetal loss of one or both twins before 24 weeks and 40 cases of intrauterine death of one or both twins after 24 weeks. A total number of 162 twin pregnancies underwent amniocentesis at 16-20 weeks' gestation. The rate of miscarriage before 24 weeks and the rate of fetal loss at any stage of pregnancy in the group that underwent amniocentesis was 10.49% and 13.58%, respectively, compared to 5.11% and 6.52% that did not undergo amniocentesis. Multivariable regression analysis showed that factors providing a significant independent contribution in the prediction of miscarriage and fetal loss at any stage of pregnancy were monochorionicity (MC), large intertwin discordance in crown-rump length (CRL), low Pregnancy Related Plasma Protein (PAPP-A) MoM and nuchal translucency (NT) above 95th centile. Amniocentesis in twin pregnancies does not provide a significant contribution in the prediction of miscarriage or fetal loss at any stage of pregnancy.

Management Options for Fetal Bronchopulmonary Sequestration.

To evaluate the prenatal course and perinatal outcome of fetuses with bronchopulmonary sequestration (BPS) managed expectantly or using minimally invasive methods. This was a retrospective study of 29 fetuses with suspected BPS managed between 2010 and 2021 in three fetal medicine centers in Poland. Medline was searched to identify cases of BPS managed expectantly or through minimally-invasive methods. In 16 fetuses with BPS, there was no evidence of cardiac compromise. These fetuses were managed expectantly. Thirteen hydropic fetuses with BPS qualified for intrauterine intervention: a thoraco-amniotic shunt (TAS) was inserted in five fetuses, laser coagulation of the feeding vessel was performed in seven cases, and one fetus had combined treatment. In the combined data from the previous and the current study of various percutaneous interventions for BPS associated with hydrops, the survival rate was 91.2% (31/34) for TAS, 98.1% (53/54) for laser coagulation, and 75% (3/4) for intratumor injection of sclerosant. After taking into account cases with available data, the rate of preterm birth before 37 weeks in the group treated with laser coagulation was 14.3% (7/49) compared to 84.6% (22/26) in the group treated with TAS. The need for postnatal sequestrectomy was lower in the group of fetuses treated with laser coagulation 23.5% (12/51) in comparison to fetuses treated with TAS 84% (21/26). In fetuses with BPS without hydrops, progression of the lesion's volume, leading to cardiac compromise, is unlikely. In hydropic fetuses with BPS, intrauterine therapy using minimally invasive methods prevents fetal demise. Both, the rate of preterm birth and the need for postnatal surgery is significantly lower in the group treated with laser coagulation compared to the group treated with TAS.

Combined screening for early and late pre-eclampsia and intrauterine growth restriction by maternal history, uterine artery Doppler, mean arterial pressure and biochemical markers.

BACKGROUND: Pre-eclampsia is a systemic disease connected with high maternal and fetal morbidity and mortality. Despite significant progress achieved in perinatal medicine, pre-eclampsia is still one of the most significant current problems in obstetrics. OBJECTIVES: The aim of the study was to establish diagnostic algorithms for early and late pre-eclampsia (PE) and intrauterine growth restriction (IUGR). MATERIAL AND METHODS: A total of 320 pregnant women between 11 + 0 and 13 + 6 weeks of gestation were recruited for a case-control study. The study group consisted of 22 patients with early PE, 29 patients with late PE and 269 unaffected controls. The following parameters were recorded: maternal history, mean arterial pressure (MAP), mean uterine artery pulsatility index (UtA-PI), and the concentrations of placental growth factor (PlGF), pregnancy-associated plasma protein A (PAPP-A) and free beta-human chorionic gonadotropin (free ß-hCG). RESULTS: A multivariable stepwise logistic regression analysis indicated that the best screening model for the prediction of early PE is based on a combined analysis of maternal risk factors, UtA-PI and PlGF levels (sensitivity: 91%; specificity: 84%). The best screening model for the prediction of late PE is based on a combined analysis of maternal risk factors, UtA-PI and MAP (sensitivity: 85%; specificity: 83%). The most effective screening model for the prediction of IUGR is based on a combined analysis of maternal risk factors, UtA-PI and PlGF concentrations (sensitivity: 91%; specificity: 83%). CONCLUSIONS: The integrated model of screening established in this study can be a valuable method to identify patients at increased risk of developing pre-eclampsia and related complications. The ability to predict the occurrence of pre-eclampsia in early pregnancy would enable maternal and fetal morbidity to be reduced through the introduction of strict obstetric surveillance as well as planned delivery in a reference center.
