Objective: To examine the association between cavum septum pellucidum (CSP) and corpus callosum (CC) length and width measurements in mid-trimester sonographic screening in normal fetuses.
Methods: This prospective cohort study examined 152 pregnant women who underwent mid-trimester sonographic fetal anomaly screening. CSP and CC lengths and their anterior, middle, and posterior width measurements were examined sonographically. The association between length and width measurements of both structures, gestational week and CSP ratio (length/width) were evaluated.
Results: The mean CSP length was 7.96 ± 1.09 mm, and the mean middle width was 3.43 ± 0.82 mm. The mean CC length was 20 ± 3.76 mm, and the mean middle width was 3.43 ± 0.82 mm. There was a positive correlation between CSP and CC lengths (r = 0.691, p < 0.001). There was also a significant correlation between CSP and CC anterior, middle and posterior widths (anterior (r = 0.366, p < 0.001), middle (r = 0.305, p < 0.001), and posterior (r = 0.233, p = 0.004)). All CSP and CC measurements were correlated with gestational age, biparietal diameter (BPD), and head circumference (HC) (p < 0.001, for all). The CSP ratio was not related to CC dimensions (p > 0.05, for all) and also decreased with the increase in BPD and HC dimensions (r = -0.186, p = 0.022, and r = -0.174, p = 0.032; respectively).
Conclusion: In normal fetuses, the length and width of the CC and CSP structures developed in relation to each other, as well as to the gestational week, BPD, and HC dimensions. In addition, while the CSP ratio was not found to be associated with CC dimensions, it decreased due to the increase in BPD and HC sizes.

OBJECTIVETo evaluate the application and effectiveness of prenatal ultrasound in diagnosing and managing conjoined twins.METHODSA retrospective analysis was conducted on 20 cases of conjoined twins diagnosed at our hospital between January 2016 and December 2022. The types of conjoined twins, ultrasonographic characteristics, and associated anomalies were assessed.RESULTSThe gestational age at diagnosis ranged from 10 to 35 weeks, with an average of 14.21 ± 5.69 weeks. Thirteen cases were detected in the first trimester, five in the early second trimester, one at 23 + 2 weeks, and one at 35 weeks. Thoracopagus was the most common type (11 cases, 55%), followed by omphalopagus (4 cases, 20%), cephalopagus (4 cases, 20%), and parapagus dicephalus (1 case, 5%). In the first trimester, the most common abnormalities observed included increased nuchal translucency (NT), cystic hygroma, hydrops fetalis, and generalized edema. Major birth defects identified in conjoined twins were omphalocele (3 cases), congenital heart malformations (3 cases), neural tube defects (2 cases), urachal cyst (1 case), and umbilical cyst (1 case). Pregnancy was terminated in 18 cases, one case resulted in spontaneous abortion during the second trimester, and one case was delivered by cesarean section at 37 weeks, with successful separation and recovery.CONCLUSIONPrenatal ultrasound is the primary diagnostic tool for conjoined twins. It effectively assesses the extent of twin fusion, provides critical information for clinical decision-making, and aids in the management of obstetric care.

BackgroundTransthoracic echocardiography (TTE) is widely used for assessing patients in the intensive care unit, with cardiac output measurement being crucial for hemodynamic monitoring. This is achieved by measuring the velocity‐time integral (VTI) of the left ventricular outflow tract (LVOT), which serves as a surrogate of stroke volume. However, conducting TTE in the critical care setting presents several challenges. Our primary objective was to investigate the relationship between carotid corrected flow time (cCFT) and LVOT VTI. Additionally, we aimed to determine the threshold cCFT value that reliably predicts a normal LVOT VTI.Materials and MethodsThis proof‐of‐concept study involves a post‐hoc analysis from a diagnostic accuracy investigation conducted in a medical‐surgical intensive care unit. We included patients admitted to the ICU from December 2021 to January 2022. We used a phased array transducer to measure the cCFT at the left supraclavicular fossa and the LVOT VTI in an apical 5‐chamber view.ResultsWe included 22 patients. The Spearman coefficient between LVOT VTI and cCFT was 0.82 (p < 0.0001). The area under the ROC curve for cCFT to predict LVOT VTI equal to or greater than 17 cm was 0.871 (95% CI 0.660–0.974). A cCFT exceeding 283 ms predicted LVOT VTI equal to or greater than 17 cm with a sensitivity of 93.3% (95% CI 68.1% to 99.8%) and specificity of 85.7% (95% CI 42.1% to 99.6%).ConclusionThe cCFT, measured using a novel technique with a phased array transducer, shows a strong correlation with LVOT VTI. Additionally, cCFT predicts a normal LVOT VTI with good sensitivity and specificity in critically ill patients. Larger studies are warranted to validate these findings.

ObjectiveThe purpose of this study was to determine if fetuses with deceleration of growth velocity resulting in an EFW <10th percentile increase their growth above the 10th percentile following 2 weeks of maternal rest in the left lateral recumbent position.MethodsThis was a retrospective observational study of 265 fetuses with the prenatal diagnosis of an EFW <10th percentile. Fetuses were classified by four definitions of abnormal growth velocity: (1) a growth velocity less than 20 g/day, (2) 30 percentile decrease in the EFW, (3) 50 percentile decrease in the EFW, and (4) abnormal growth trajectory. Once the fetuses were identified with an EFW <10th percentile the patient was requested to begin 2 weeks of rest in the left lateral recumbent position during her waking hours following which the EFW was reassessed 2 week later to determine the effect of maternal rest on the EFW.ResultsIrrespective of the four types of decreased growth velocity described in the methods section, there was as significant increase (p < 0.001) in the EFW following 2 weeks of maternal rest as follows: (1) growth less than 20 g/day (75%); (2) decrease of 30 or more EFW percentiles (79%); (3) decrease of 50 or more EFW percentiles (64%); and abnormal growth trajectory (77%).ConclusionsThis suggests an important role of increased maternal cardiac output as the result of resting in the left lateral recumbent position that may be associated with improved fetal growth. These observations should be the basis for future prospective randomized trials to test this hypothesis.

ObjectivesTo evaluate the accuracy of ultrasound estimates of fetal weight made by residents.MethodsA cross‐sectional study was conducted on consecutive pregnancies attended in an obstetric ward. All participants provided their consent to participate. Inclusion criteria were singleton pregnancies with ultrasound evaluation and delivery within 14 days. Congenital abnormalities and stillbirths were excluded. Ultrasound scans were performed by two residents, one observer per subject, following standardized methodology and supervised by senior staff. Fetal weight was calculated using the four‐parameter Hadlock 1985 formula. Birth weight was measured using a standard clinical scale. Bland–Altman and mixed‐effects analyses were performed.ResultsIn a 6‐month period, 95 gestations were recruited at 30–41 weeks, and birth weights ranged from 1200 to 4080 g. The bias between methods was −28 g (CI95%, −74 to 18) with 95% limits of agreement of ±440 g. The 95% deviation between methods was of ±16%. Parity had the most significant effect on the bias between methods; operator and maternal weight had no significant effect.ConclusionsSupervised measurement of fetal weight by residents demonstrated high accuracy. Parity bias may be associated with visceral fat deposition independent of maternal weight gain. A methodology for medical evaluation is presented.

PurposeTo evaluate the safety and efficacy of ultrasound‐guided percutaneous thrombin injection for the treatment of upper extremity pseudoaneurysms.MethodsAn institutional database containing 8,316,467 radiology reports was searched for suitable cases over a 241‐month period. Fourteen female and 10 male patients, average age of 69.7 years (range 29–93) underwent a total of 26 procedures for the management of upper extremity pseudoaneurysms, involving the radial (n = 9), brachial (n = 9) or other upper extremity arteries (n = 6). Baseline demographic and pseudoaneurysm characteristics were documented, together with primary and secondary success, failures, and complications. All procedures were performed with real‐time ultrasound guidance.ResultsThe mean pseudoaneurysm volume was 9.93 cm3 (range 0.06–111.62 cm3). Twelve cases were related to central line placement or arterial access. Primary success was obtained in 50% (n = 12) after a single ultrasound‐guided thrombin injection, and secondary success was achieved in an additional six (for a total success of 75%). Success was highest for the treatment of brachial artery pseudoaneurysms (87.5%), and in those who were diagnosed within 7 days of the inciting event, findings that were statistically significant (p‐value 0.046 and 0.002, respectively).ConclusionsUltrasound‐guided percutaneous thrombin injection is safe and effective for managing upper extremity pseudoaneurysms.

Inflammatory liposarcoma is one of the rarest subtypes of well-differentiated liposarcoma. We present an extremely rare case of well-differentiated inflammatory liposarcoma that occurs in the muscularis of the gallbladder, which was difficult to diagnose before surgery due to the lack of specific clinical and imaging findings. Since cyclin-dependent kinase 4 (CDK4) and murine double minute 2 (MDM2) both displayed amplification in this case, they are not only important markers for auxiliary diagnosis but also the focus of current targeted therapy.

ObjectivesThis study aims to compare the elastographic properties of the ovaries of patients with poor ovarian response (POR) with healthy controls by using real‐time ultrasound tissue elastography and to investigate the predictive value of ovarian strain ratio (OSR) in the diagnosis of POR.Materials and MethodsA cross‐sectional study was conducted among infertility patients. OSR measurements of 46 women diagnosed with POR and 41 healthy controls with male infertility were performed by real‐time ultrasound tissue elastography. Ovarian volume, OSR, antral follicle count (AFC), age, body mass index (BMI), anti‐mullerian hormone (AMH), follicle stimulating hormone (FSH), and estradiol (E2) values, were compared between the groups. A receiver operating characteristic curve was used to compare the sensitivity and specificity of OSR, AFC, AMH, FSH, and E2 for POR diagnosis.ResultsPatients with POR were significantly older, had a lower duration of infertility, lower AMH, higher FSH, higher E2, lower AFC and ovarian volume (p < 0.01, p = 0.02, p < 0.01, p < 0.01, p < 0.01, p < 0.01, p < 0.01, respectively). The mean OSR of both ovaries was similar between the groups. For the diagnosis of POR, the sensitivity and specificity for AMH were 97.5% and 100%, for AFC were 86.7% and 97.6%; for FSH were 66.7% and 80.5%, for E2 were 53.3% and 90.2%, respectively.ConclusionsThe significant independent predictors of the POR were AMH, AFC, and FSH, with no additional significant contribution from OSR. However, considering the relationship between POR and ovarian fibrosis, it is recommended to investigate this issue in more comprehensive studies.
本研究旨在利用实时超声组织弹性成像技术比较卵巢反应不良（POR）患者与健康对照组卵巢的弹性特性，并探讨卵巢应变比（OSR）在诊断 POR 中的预测价值。通过实时超声组织弹性成像技术对 46 名确诊为 POR 的女性和 41 名男性不育症健康对照者进行了卵巢应变比测量。比较了各组之间的卵巢体积、OSR、前卵泡计数（AFC）、年龄、体重指数（BMI）、抗苗勒氏激素（AMH）、促卵泡激素（FSH）和雌二醇（E2）值。用接收器操作特征曲线比较了 OSR、AFC、AMH、FSH 和 E2 对 POR 诊断的敏感性和特异性。结果POR患者的年龄明显偏大，不孕时间较短，AMH较低，FSH较高，E2较高，AFC和卵巢体积较小（分别为p < 0.01, p = 0.02, p < 0.01, p < 0.01, p < 0.01, p < 0.01, p < 0.01）。两组患者卵巢的平均OSR相似。对于 POR 的诊断，AMH 的敏感性和特异性分别为 97.5%和 100%，AFC 的敏感性和特异性分别为 86.7%和 97.6%，FSH 的敏感性和特异性分别为 66.7%和 80.5%，E2 的敏感性和特异性分别为 53.3%和 90.2%。然而，考虑到 POR 与卵巢纤维化之间的关系，建议对这一问题进行更全面的研究。
