Doppler changes of uterine arteries and fetal umbilical arteries blood flow in cases of late third trimester oligohydramnios

Sixty pregnant women were included in this study and classified into two groups: Group A [control group] included 30 pregnant women in the third trimester with normal amniotic fluid index [AFI] and group B [study group] included 30 pregnant women in the third trimester complicated by oligohydramnios [AFI less than fifth percentile correspond to gestational age]. Color Doppler ultrasound was done for the evaluation of blood flow velocity wave form [Vm] of maternal uterine arteries and fetal umbilical arteries. The outcome of pregnancy was reported. AFI and post date pregnancy were statistically significantly higher in the control group than in the study group. The mean blood flow velocity [Vm] was significantly lower in the study group than in the control group; whereas, the mean systolic/diastolic ratio S/D and the mean resistance index [RI] were significantly higher in the study group than in the control group

Effect of hysterectomy on ovarian blood supply and function

The objective of this study was to determine whether hysterectomy has an effect on ovarian blood supply and functions or not and to make a decision to preserve or remove apparently normal ovaries in premenopausal women. Fifty premenopausal women, where ovarian blood supply and function were assessed before and after hysterectomy, were included in this study. Transvaginal color Doppler resistance index values of ovarian artery and hormonal levels [E2, FSH and LH] were measured. At the end of the 6th postoperative month, all these measurements were repeated. Serum levels of all hormones remained unchanged for six months after surgery. There was no significant difference between the pre and postoperative resistance index of ovarian arteries
