The aim of this study was to evaluate the blood flow characteristics o
f the uterine artery and intratumoral vessels in patients with GTD. Tw
elve patients with GTD were evaluated with TVS, and 11 also had CFD so
nography performed. Spectral analysis of both uterine artery and sampl
ed intratumoral and intramyometrial vessels revealed systolic frequenc
ies and PI that were significantly higher in the uterine artery than i
n sampled intratumoral vessels (P < 0.05). Uterine artery PI correlate
d significantly with age (P = 0.043), uterine size (P = 0.003), and be
ta-HCG titer (P = 0.03). Intratumoral PI correLated significantly with
uterine size (P = 0.05). Intratumoral PI did not correlate with patie
nt age, the shape or orientation of the uterus, presence or absence of
subendometrial halo, endometrial thickness or echogenicity, or impres
sion 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 pat
ients with GTD. The PI is strongly associated with prognosis and corre
Lates with BETA-HCG titers.
