[Transvaginal Doppler sonography for measuring blood flow in the pelvis].
This is a report on our first experience with transvaginal Doppler sonography. In this way we can measure the different blood flow parameters in the internal iliac, ovarian and uterine arteries during the menstrual cycle. The detection of the particular vessels and their typical waves of flow are described in detail. In 279 measurements taken from 107 patients in the stimulated cycle we could show that the systolic blood flow after induction of ovulation or before ovulation increases significantly both in the internal iliac and in the ovarian artery. This experience made in the stimulated cycle could also be confirmed in the natural cycle where a preovulatory increase of systolic blood flow in the uterine artery was also noticed. During administration of a contraceptive pill only slight uncoordinated increases of blood flow could be registered. Any possible connections between the above mentioned changes with factors depending on the blood flow or on organic resistance on one hand or on endocrine parameters on the other, and possible practical applications, are discussed.
