Abstract


RI (Resistance index) values of uterine artey in 14 patient with GTD (Gestational trophoblstic desease) (10 patients with H-mole and 4 patients with invasive mole) were measured using color doppler ultrasonogram. 10 non-pregnant and 10 early
second
trimester pregnant volunteers were assessed in a similar fashion to act as control groups. The mean RI values were; non-pregnant group is 0.868±0.025, pregnant group is 0.773±0.062, H-mole group is 0.781±0.065, invasive mole group is
0.606±0.139.
So, the mean RI values were lower in the patients with invasive mole group when compared with the non pregnant, early pregnant and H-mole group. But there is no statistically significant difference between H-mole and normal pregnant.
The uterine circulation in invasive mole showed abnormal blood flow which shows high diastolic component within the tumor mass and myometrium, the RI value was 0.47. But this phenomenon is disappeared after remission by chemotherapy.
The mean RI value of uterine arteries with tumor site was increased tendency from 0.529±0.140 to 0.748±0.151 after remission by chemotherapy.
From these results, we concluded that the color doppler sonogram is useful in the diagnosis and follow up of invasive mole by measuring RI values of uterine artery and blood flow within tumor mass.
