Differential diagnosis from other forms of gestational trophoblastic neoplasia (GTN) is critical owing to major differences in prognosis and treatment. Doppler measurement of uterine artery (UtA) pulsatility index (PI) has been proposed for the diagnosis and management of GTN. The aim of this study was to evaluate the added value of UtA-PI Doppler measurement during the standard transvaginal ultrasound (TVS) assessment, in patients with PSTT as compared to those with other GTN.</p><p><strong>Methods: </strong>This was a single-center prospective cohort study involving ultrasound assessment of all GTN cases referred to and treated at the trophoblast unit of San Raffaele Hospital, Milan, Italy, between 2011 and 2023. TVS assessment included: grayscale analysis for the detection of myometrial or endometrial abnormalities, color and power Doppler assessment of lesions with scoring of vascularization, and spectral pulsed-wave Doppler for measurement of mean UtA-PI from the left and right UtAs. Sonographic findings were compared between patients with PSTT and those with other forms of GTN (postmolar, invasive mole or choriocarcinoma), using non-parametric two-tailed statistical analysis.</p><p><strong>Results: </strong>A total of 73 GTN cases were recruited, comprising nine (12.3%) with PSTT and 64 (87.7%) with other GTN. A significant difference was detected between other-GTN and PSTT cases when comparing rates of substantial endometrial vascularity on Doppler (50% vs 0%; P = 0.013) and mean UtA-PI measurements (median, 1.5 (interquartile range (IQR), 1.0-2.4) vs 2.2 (IQR, 1.5-2.7); P = 0.014; area under the receiver-operating-characteristics curve, 0.768 (95% CI, 0.610-0.888)).</p><p><strong>Conclusions: </strong>This study describes UtA-PI as a novel and effective marker allowing for the ultrasound differentiation of PSTT from other forms of GTN. The significantly higher mean UtA-PI and lower endometrial vascularity observed in PSTT as compared with other GTN suggests a unique vascularization pattern, with a potential role in differential diagnosis and management. © 2025 The Author(s).

All women underwent a standardized interview, pelvic organ prolapse quantification (POP-Q) assessment and four-dimensional transperineal ultrasound. 2D oblique parasagittal ultrasound imaging was performed by rotating the transducer 10-20° from the midline to line up the main transducer axis with the fiber direction of the puborectalis muscle, followed by a full parasagittal sweep of the hiatus at rest. Postprocessing of archived ultrasound volume data was performed at a later date, blinded to all other data.

We aimed to quantify the association of race and ethnicity with OASI, stratified by parity, obstetric history and mode of delivery. Secondary aims were to explore variations in OASI rates among racial subgroups and by immigration status (foreign-born vs USA-born).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;We conducted a cross-sectional study of 12 501 183 vaginal births in the USA from January 2016 to December 2021 using birth-certificate data obtained from the National Vital Statistics System. Cox proportional hazard regression models were fitted, with gestational age as the timescale, to quantify the association of self-reported race and ethnicity with OASI, with adjustment for several confounders. The maternal race and ethnicity groups included: American Indian or Alaska Native (AIAN), Asian, Black, Hispanic, Native Hawaiian and other Pacific Islander, White and mixed race. Models were stratified by number of previous births and the occurrence of Cesarean delivery (CD) among prior births. This resulted in three groups: primiparous (i.e. only the index birth); multiparous without a previous CD; and multiparous with at least one previous CD. Within each stratum, we further grouped individuals by mode of delivery in the index birth, as spontaneous vaginal delivery (SVD), operative vaginal delivery (OVD) with forceps and OVD with vacuum.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;In primiparous individuals who had a vaginal birth, the overall OASI rate was 2.2%, but it varied widely by mode of delivery (SVD, 1.7%; OVD with forceps, 14.8%; OVD with vacuum, 6.6%). Asian primiparae had higher OASI hazards compared with White primiparae, irrespective of mode of delivery (SVD: adjusted hazard ratio (aHR), 1.69 (95% CI, 1.64-1.73); OVD with forceps: aHR, 1.48 (95% CI, 1.38-1.58); OVD with vacuum: aHR, 1.51 (95% CI, 1.44-1.58)), while AIAN and Black primiparae had inconsistent associations with OASI rate depending on mode of delivery, when compared with White primiparae. In multiparous individuals without a previous CD, the rates of OASI were lower than those seen in primiparae (SVD, 0.5%; OVD with forceps, 7.5%; OVD with vacuum, 3.2%) and the association of race and ethnicity with OASI varied by mode of delivery for all race groups except Asian, in whom it was consistently associated with a 1.5-2.1-times higher hazard of OASI. Among multiparous individuals with a previous CD, overall OASI rates were similar to those seen in primiparae (SVD, 1.3%; OVD with forceps, 11.8%; OVD with vacuum, 5.1%). In this group, the only associations of race and ethnicity with OASI were higher hazards among Asian vs White individuals who had a SVD (aHR, 2.16 (95% CI, 1.97-2.36)) and an OVD with vacuum (aHR, 1.65 (95% CI, 1.39-1.96)).
