Identification of Pelvic Congestion Syndrome Using Transvaginal Ultrasonography. A Useful Tool.

The gold standard for the diagnosis of pelvic congestion syndrome (PCS) is venography (VG), although transvaginal ultrasound (TVU) might be a noninvasive, nonionizing alternative. Our aim is to determine whether TVU is an accurate and comparable diagnostic tool for PCS. An observational prospective study including 67 patients was carried out. A TVU was performed on patients, measuring pelvic venous vessels parameters. Subsequentially, a VG was performed, and results were compared for the test calibration of TVU. Out of the 67 patients included, only 51 completed the study and were distributed in two groups according to VG results: 39 patients belonging to the PCS group and 12 to the normal group. PCS patients had a larger venous plexus diameter (15.1 mm vs. 12 mm; p = 0.009) and higher rates of crossing veins in the myometrium (74.35% vs. 33.3%; p = 0.009), reverse or altered flow during Valsalva (58.9% vs. 25%; p = 0.04), and largest pelvic vein ≥ 8 mm (92.3% vs. 25%). The sensitivity and specificity of TVU were 92.3% (95% CI: 78.03-97.99%) and 75% (95% CI: 42.84-93.31%), respectively. In conclusion, transvaginal ultrasonography, with the described methodology, appears to be a promising tool for the diagnosis of PCS, with acceptable sensitivity and specificity

Intrapartum transperineal ultrasound used to predict cases of complicated operative (vacuum and forceps) deliveries in nulliparous women

IntroductionThe objective of this study was to investigate the predictive value of intrapartum transperineal ultrasound in the identification of complicated operative (vacuum or forceps) deliveries in nulliparous women.Material and methodsProspective observational study of nulliparous women with an indication for operative delivery who underwent intrapartum transperineal ultrasound before fetal extraction. Managing obstetricians were blinded to the ultrasound data. Intrapartum transperineal ultrasound was performed immediately before blade application, both at rest and concurrently with contractions and active pushing. Operative delivery was classified as complicated when one or more of the following situations occurred: three or more tractions; a third-/fourth-degree perineal tear; significant bleeding during the episiotomy repair; major tear or significant traumatic neonatal lesion.ResultsA total of 143 nulliparous women were included in the study (82 vacuum-assisted deliveries and 61 forceps-assisted deliveries), with 20 fetuses in occiput posterior position. Forty-seven operative deliveries were classified as complicated deliveries (28 vacuum-assisted deliveries, 19 forceps-assisted deliveries). No differences in obstetric, intrapartum or neonatal characteristics were observed between the study groups, with the following exceptions: birthweight (3229482 uncomplicated deliveries vs. 3623 +/- 406 complicated deliveries;
