Transvaginal color and pulsed Doppler study of uterine blood flow in the first and early second trimesters of pregnancy: normal versus abnormal.

摘要: Transvaginal color Doppler ultrasonography was used to study 131 normal early pregnancies, 30 molar 20 threatened abortions, two blighted ova, and five pregnancies with intramural myoma. Four separate parts of the maternal circulation were studied: uterine, arcuate, radial, spiral arteries. There statistical difference in RI PI among arteries (P < 0.001) all observed groups patients except those When same part compared different patients, following results reached significance: uterine artery pregnancy 0.001); arcuate radial abortion 0.01); 0.001), 0.01), 0.01). The standard values blood flow are some cases abnormal (molar pregnancy, abortion).
