Diagnostic value of transvaginal three-dimensional ultrasound combined with color Doppler ultrasound for early cesarean scar pregnancy

Abstract

Background: Our study sought to obtain data which assess the diagnostic value of transvaginal threedimensional ultrasound (3D-US) combined with color Doppler ultrasound (US) for early cesarean scar pregnancy (CSP).Methods: All participants were randomly divided into a Control group diagnosed using 3D-US and a Combination group diagnosed using 3D-US combined with color Doppler US. The preoperative US results were compared with postoperative pathological results. The diagnostic coincidence rate, sensitivity, and specificity of these two examination methods were compared, and their diagnostic results for different types of CSP were analyzed. Finally, the diagnostic effects of both methods were compared and analyzed, and the imaging of CSP was summarized. Results:The diagnostic accuracy of transvaginal 3D-US combined with color Doppler US (92.96%) was significantly higher than that of transvaginal 3D-US (71.83%). For different types of CSP, the diagnostic rate of CSP with mixed echogenic mass and partial implantation of gestational sac in the Combination group was markedly higher than that in the Control group.Conclusions: Additionally, the sensitivity, specificity, and area under the receiver operating characteristic (ROC) curve (AUC) in the Combination group were higher than those in the Control group. Transvaginal 3D-US combined with color Doppler US can improve the sensitivity, specificity, and accuracy of diagnosis of early CSP, and has important reference value for clinical condition evaluation and treatment options.

RETRACTED: Meta‐analysis comparing different ultrasound detection methods to accurately assess wound healing and scar formation after caesarean section

“…Through an exhaustive review, our journey from 1842 initial articles was distilled to a core of seven seminal studies, 10 , 11 , 12 , 13 , 14 , 15 , 16 meticulously catalogued in Table 1 . These selected works probe deeply into the nuanced comparison between transvaginal ultrasonography (TU) and conventional abdominal ultrasonography (CU) in surveilling caesarean section wound healing among twin pregnancies.…”

Recognition of the Type of Cesarean Scar Pregnancy in First Trimester Sonography

“…The use of color Doppler may enhance its diagnostic acuity. 11 The identification of the type of CSP with first trimester sonography may also be pertinent to patient counseling, as the sort of subsequent surgical treatment may be dependent on the findings. 12 Determining the type of CSP by virtue of recognizing the site of ectopic trophoblast implantation and its relative position with the surrounding tissue is particularly useful in this context.…”

Conservative Management of Cesarean Scar Pregnancy: A Case Report and Literature Review

“…The ultrasound diagnostic criteria for CSP were defined as follows [ 4 , 10 , 11 ]: Empty uterus with clearly visualized endometrium Empty cervical canal Gestational sac implanted in the lower anterior uterine segment at the presumed site of the cesarean section incision scar Thin or absent myometrium between the gestational sac and the bladder (the majority of cases have a myometrium thickness<5 mm). “Sliding organ sign” Doppler Flow at the previous cesarean scar …”
