title: Transvaginal color flow Doppler sonography in the assessment of gestational trophoblastic disease.
abstract: The aim of this study was to evaluate the blood flow characteristics of the uterine artery and intratumoral vessels in patients with GTD. Twelve patients with GTD were evaluated with TVS, and 11 also had CFD sonography performed. Spectral analysis of both uterine artery and samples intratumoral and intramyometrial vessels revealed systolic frequencies and PI that were significantly higher in the uterine artery than in sampled intratumoral vessels (P < 0.05). Uterine artery PI correlated significantly with age (P = 0.043), uterine size (P = 0.003), and beta-HCG titer (P = 0.03). Intratumoral PI correlated significantly with uterine size (P = 0.05). Intratumoral PI did not correlate with patient age, the shape or orientation of the uterus, presence or absence of subendometrial halo, endometrial thickness or echogenicity, or impression of myometrial invasion. Regression analysis of beta-HCG titers on uterine artery and intratumoral PI revealed a linear association. TVS and color flow Doppler sonography are useful in the assessment of patients with GTD. The PI is strongly associated with prognosis and correlates with beta-HCG titers.
