Abstract
Aim: The purpose of this study was to evaluate the diagnostic value of colour Doppler sonography for ovarian veins. The clinical incidence of ovarian venous lesions is relatively low and often overlooked. The ovarian veins are located deep in the pelvis, and they are relatively elongated, which could make medical imaging more difficult. Therefore, there is limited literature on the diagnosis of ovarian venous disease. The purpose of this study was to evaluate the diagnostic value of colour Doppler sonography towards ovarian vein.
Methods: A total of 37 consecutive patients with clinically suspected ovarian venous disorders were included. All the patients underwent colour Doppler sonography. CTV was performed in 31 patients, while retrograde phlebography was performed in 6 patients. CT/phlebography was the established diagnostic criterion for ovarian vein disorders. The SPSS 22.0 program was used for statistical analysis. Sensitivity, specificity, and positive and negative predictive values for colour Doppler sonography were calculated. k-test was used to evaluate consistency between colour Doppler sonography and CT/phlebography.
Results: In the 37 patients,18 cases were positive for ovarian vein disorders and 19 cases were negative, as assessed with colour Doppler sonography. The associated lesions included ovarian vein thrombosis (7 cases), ovarian varicocele (3 cases), and ovarian venous leiomyoma (8 cases). The calculated values of sensitivity, specificity, and positive and negative predictive value were 94.4%, 94.7%, 94.4%, and 94.7%, respectively. The overall accuracy rate was 94.9%. The K level of the degree of agreement between CT/phlebography and colour Doppler sonography was 0.892.
Conclusion: Colour doppler sonography can provide sufficient imaging information. In clinical ultrasonography, attention should be paid to recognizing and detecting ovarian venous lesions.
