✦ Synopsis

Objective:

This investigation was undertaken to evaluate the predictive value of the blood flow velocity as measured by transvaginal color doppler sonography (cds) and conventional sonographic criteria in the preoperative assessment of ovarian tumors.

Methods:

98 patients who were admitted for surgery with a suspicion of an adnexal mass (69 benign tumors, 4 borderline tumors, and 25 malignant tumors) were prospectively studied with transvaginal sonography (tvs) and cds. pulsatility index of blood flow velocity waveforms was evaluated by cds and compared with established sonographic criteria for discriminating between benign and malignant ovarian tumors.

Results:

Tvs had a sensitivity of 91% and a specificity of 84% in detecting malignant ovarian tumors compared with cds with a sensitivity of 90% and a specificity of 74%, using 1.1 as a cut-off value for the pulsatility index. the specificity of cds was higher in postmenopausal (88%) than in premenopausal (63%) patients. using tvs and cds combined, the sensitivity and specificity of diagnosing malignant ovarian tumors could be increased to 95% and 86%.

Conclusion:

In premenopausal patients, tvs is clearly a more sensitive and more specific technique than cds in correctly identifying benign and malignant ovarian tumors, whereas in postmenopausal patients, cds gives useful additional information concerning blood vessel resistance. if cds is used as an additional technique to tvs, it can increase the sensitivity and specificity of tvs in discriminating between benign and malignant ovarian tumors.
