Abstract:
Objective:To explore the application value of three-dimensional ultrasound(3D-US)combined with two-dimensional trans vaginal sonography(2D-TVS)in diagnosing uterine arteriovenous fistula(UAVF).Methods:A total of 36 patients with suspected UAVF who admitted to Baoding Maternal and Child Health Care Hospital from January 2024 to December 2024 were retrospective selected.All of them underwent 3D-US,2D-TVS and combined examinations of 3D-US and 2D-TVS.The gynecological intravenous contrast-enhanced ultrasound was used as the"gold standard"to compare and analyze the sensitivity,specificity,accuracy rate,positive predictive value and negative predictive value of 3D-US,2D-TVS and the combined examination of them.The diagnostic efficacies of the three diagnostic methods were calculated by the four-grid table method and the analysis of the receiver operating characteristic(ROC)curve.The detection rates of 2D-TVS and combined examination of 2D-TVS and 3D-US for UAVF imaging signs were compared.Results:In 36 patients,gold standard confirmed 26 positive cases and 10 negative cases.The sensitivity,specificity,accuracy rate,positive predictive value and negative predictive value of 2D-TVS examination were respectively 69.23%,80.00%,72.22%,90.00%and 50.00%.These indicators of 3D-US examinations were respectively 84.62%,90.00%,86.11%,95.65%and 69.23%.These indicators of the combined examination were respectively 92.31%,90.00%,91.67%,96.00%and 81.82%.There were not statistically significant differences in these indicators among the three diagnostic methods(P>0.05).However,the sensitivity,accuracy rate of the combined examination were respectively higher than those of 2D-TVS examination,and the differences were statistically significant(x2=4.457,4.600,P<0.05).The detection rates of the sings included lake-like,multicolored Mosaic and blood flow spectrum of high-speed low-resistance in UAVF images of the combined examination were all higher than those of 2D-TVS examination,and the differences were statistically significant(x2=4.000,4.431,4.600,P<0.05).Conclusion:The combination of 3D-US and 2D-TVS can significantly improve the diagnostic sensitivity,accuracy and detection rate of imaging signs in the diagnosis for UAVF,which has important clinical application value.
