Contrast-enhanced US to Improve Diagnostic Performance of O-RADS US Risk Stratification System for Malignancy.

Background The Ovarian-Adnexal Reporting and Data System (O-RADS) has limited specificity for malignancy. Contrast-enhanced US can help distinguish malignant from benign lesions, but its added value to O-RADS has not yet been assessed. Purpose To establish a diagnostic model combining O-RADS and contrast-enhanced US and to validate whether O-RADS plus contrast-enhanced US has a better diagnostic performance than O-RADS alone.

Feasibility of Transabdominal Real-time CDFI and HDFI Techniques for Fetal Pulmonary Vein Display in the First Trimester.

Objective: This study aimed to assess the feasibility and usefulness of transabdominal color Doppler flow imaging (CDFI) technology and the high-definition flow imaging (HDFI) technique in detecting fetal pulmonary veins (PVs) in the first trimester (11-13 weeks).

Methods: From December 2018 to October 2019, 328 pregnant women with 328 normal singleton fetuses (crown-rump length: 45-84 mm) who had undergone CDFI and HDFI scans for fetal heart and vessel examination were enrolled in this study. The cases were divided into three groups according to the gestational age: group A, 11 -11 weeks; group B, 12 -12 weeks; and group C, 13 -13 weeks.

Spontaneous renal hemorrhage secondary to choriocarcinoma in a man with congenital hypospadias and cryptorchidism: a case report and literature review.

Background: Choriocarcinoma is a rare malignant germ-cell tumour, most commonly found in adult women. It infrequently presents as spontaneous renal haemorrhage (SRH). Genital malformation and SRH secondary to choriocarcinoma has previously been only reported in females.

Clinical Outcomes after Selective Fetal Reduction of Complicated Monochorionic Twins with Radiofrequency Ablation and Bipolar Cord Coagulation.

Aims: To review pregnancy outcomes, complication rates and neonatal neural development of selective termination procedures for complicated monochorionic (MC) twins.

Methods: This was a retrospective review of the pregnancies that underwent selective reduction with radiofrequency ablation (RFA) and bipolar cord coagulation (BCC) in our institution.

Results: Forty-eight cases underwent selective reduction with BCC and the remaining 45 with RFA.

Hepatoprotective effect of ulinastatin in a rat model of major hepatectomy after obstructive jaundice.

Background: To date, major hepatectomy with obstructive jaundice is still a highly risky and difficult surgery because of the high rate of complications. An excessive inflammatory response may be the primary hindrance to postoperative recovery of liver function.

Aims: Recent research has demonstrated that ulinastatin blocks the release of inflammatory factors and prevents the cytokine cascade reaction.

Date-independent parameters: an innovative method to assess fetal cerebellar vermis.

The objectives of this paper were to identify gestational age-independent parameters for cerebellar vermis (CV) evaluation and examine their use in CV integrity assessments. Using three-dimensional ultrasonography, we obtained the following measurements from 217 pregnant women carrying 18-37-week-old fetuses: the largest area of the CV, vermal craniocaudal distance (VCC), vermal anterior to posterior diameter, and vermal perimeter (VP). In addition, fetal growth parameters (biparietal diameter, head circumference femoral length [FL], humeral length, transverse cerebellar diameter, and abdominal circumference) were evaluated.

Prenatal diagnosis of prevalence of the right heart: associated anomalies and outcome predictors.

Objectives: To analyze the characteristics, associations, and outcomes of prevalence of the right heart and to evaluate the use of sonography to predict the risk of a poor prognosis in fetuses with this condition.

Methods: We conducted a retrospective cohort study of 182 fetuses with prevalence of the right heart. At the initial evaluation, the left ventricle (LV) and right ventricle (RV) sizes, left atrium and right atrium sizes, great artery diameters, appearance of the aortic arch and ductus arteriosus arch, and flow direction across the foramen ovale and aortic arch were documented.

Fetal persistent left superior vena cava in cases with and without chromosomal anomalies.

Objectives: The objectives of this study are to determine and compare the prevalence of persistent left superior vena cava (PLSVC) in chromosomally normal and abnormal fetuses and to evaluate the potential of PLSVC as a screening marker for chromosomal abnormalities.

Methods: Women undergoing routine fetal sonographic examinations were evaluated once for the presence of PLSVC. PLSVC was diagnosed on the basis of the identification of an additional vessel in the left of the pulmonary artery in a three-vessel trachea view.

[Association between fetal ventricular septal defects and chromosomal abnormalities].

Objective: To evaluate the association between fetal ventricular septal defects (VSD) and chromosomal abnormalities.

Methods: The 214 fetuses diagnosed VSD in the First Affiliated Hospital of Sun Yat-sen University from January 2008 to September 2011 were included. The VSD were categorized into 3 types: perimembranous, muscular and mixed (the defect could not be classified because the dimensions were larger than 5 mm) type.

Accuracy, agreement, and reliability of fetal cardiac measurements using 4-dimensional spatiotemporal image correlation.

Objectives: The purpose of this study was to evaluate the accuracy, agreement, and reliability of 4-dimensional sonography using spatiotemporal image correlation (STIC) in fetal cardiac measurements during the second and third trimesters.

Methods: Four-dimensional cardiac STIC volumes were acquired from 150 low-risk singleton pregnancies at gestational ages of 18 to 38 weeks. A total of 11 dimensions of the fetal heart and great vessels were analyzed by two different observers.

Four-dimensional sonography with spatiotemporal image correlation and tomographic ultrasound imaging in the prenatal diagnosis of anomalous pulmonary venous connections.

Objectives: To determine whether the use of 4-dimensional (4D) sonography with spatiotemporal image correlation (STIC) and tomographic ultrasound imaging (TUI) can provide additional information with respect to 2-dimensional (2D) echocardiography in the prenatal diagnosis of anomalous pulmonary venous connections.

Methods: The study population consisted of 10 cases that were initially suspected to have total or partial anomalous pulmonary venous connections by prenatal 2D echocardiography between January 2008 and April 2011. All 10 cases were further examined and analyzed by 4D sonography with STIC-TUI.

[Prenatal diagnosis of trisomy 18 syndrome with sonogram index scoring system].

Objective: To explore the value of sonogram index scoring system in the prenatal diagnosis of trisomy 18 syndrome.

Methods: Neonates who had prenatal sonographic screening in our tertiary center were followed up from January 2004 to December 2009. The fetuses who were suspected with abnormalities received karyotype analysis.

Prenatal surveillance of bronchopulmonary sequestration using 3-dimensional ultrasonography.

Objective: The purpose of this study was to assess the growth of fetal lung lesions using 3-dimensional ultrasonography (3DUS) and to note the clinical outcomes of infants with congenital bronchopulmonary sequestration (BPS) diagnosed prenatally.

Methods: Twenty-two cases of intrathoracic BPS diagnosed prenatally occurred between May 2005 and September 2008. The volume of the BPS lesion (V(mass)) and the volume of the fetal chest (V(chest)) were measured with the 3DUS software Virtual Organ Computer-Aided Analysis (VOCAL; GE Healthcare, Kretztechnik, Zipf, Austria).

Objective: To investigate the clinic value of ultrasonographic fetal nasal bone examination as a screening marker for Down syndrome (DS).

Methods: The study was conducted in the First Affiliated Hospital of Sun Yat-sen University from Oct 2004 to Mar 2007. Two-dimensional ultrasound was used to assess the fetal nasal bone of 1863 normal pregnancies (normal group) and 25 cases with DS fetus (study group) during their second and third trimesters.

[Quantitative analysis of cerebellar vermis in fetuses with Dandy-Walker syndrome with three-dimensional ultrasonography].

Objective: To evaluate the third plane image of the three-dimensional sonography (3D US) for the quantitative analysis of the cerebellar vermis in normal and Dandy-Walker syndrome (DWS) fetuses.

Methods: The cerebellar vermis was scanned with trans-abdominal 3D US in the second and third trimesters in 571 normal fetuses and 39 fetuses with Dandy-Walker syndrome. The surface area of the vermis in the mid-sagittal view was measured and calculated.
