“…STEER et al [58] reported the disappearance of diastolic flow in the uterine arteries during the day of ovulation. GOSWAMY et al [15] found increasing resistance index and systolic/diastolic ratio during the postovulatory drop in the serum oestradiol concentration. Increased uterine artery impedance was reported three days after the LH peak, while SCHOLTES and coleagues [54] recorded the highest pulsatility index (PI) value in the uterine arteries on the cycle day 16.…”

“…This unique vascular architecture is important in allowing a repeated sequence of endometrial growth and desquamation, as well as the process of implanation and placentation. Uterine blood flow parameters are related to the ovarian hormone levels in peripheral venous plasma [15,42]. During the menstrual cycle the endometrium is subjected to structural and functional changes primarily related to the development of the spiral arteries [10,12,13,20,55].…”

“…It is interesting that the lowest impedance to flow is observed during the time of peak luteal function during which implantation is most likely to occur [2,18,31]. Some authors as KURJAK et al [31], GOSWAMY et al [15,16], STEER et al [58], and BATTAGLIA et al [3] reported high blood supply to the uterus in the late luteal phase. In anovulatory cycles, these changes do not occur and continuous increase in RI is seen [31].…”

“…In most women, a small amount of end-diastolic flow in the uterine arteries in found in the proliferative phase but a sharp increase in end-diastolic velocities occurs between the proliferative and secretory phase [31]. End-diastolic flow absence demonstrated in some infertile patients could be connected with infertility or poor reproductive performance [15,16,31,58] or be a variant disap-pearing after a pregnancy [31] (figure 7). STEER et al [58] reported the disappearance of diastolic flow in the uterine arteries during the day of ovulation.…”

Transvaginal color Doppler has made possible to study ovarian and uterine perfusion in non-pregnant and pregnant patients, thus advancing the understanding of the early human development. RI of follicular blood flow starts decreasing prior to ovulation reaching its nadir at ovulation. It is considered that apart from hormonal factors the angiogenesis is also involved. The mature corpus luteum shows increased blood flow velocity in relation to preovulatory follicle. Comparing RI values of luteal blood flow of normal and ectopic pregnancy no difference was found. But in threatened, incomplete and missed abortions the resistance and pulsatility indices were significantly higher than in normal pregnancy. The follow up of the luteal flow might have a prognostic value in a group of patients with threatened abortion. In women with spontaneous cycles the day preceding the ovulation impedance to uterine flow velocity starts decreasing. Alterations in flow velocity patterns of the radial and spiral arteries in spontaneous ovulatory cycles are paralleling blood flow dynamics of the uterine arteries. In stimulated cycles RI increases the day before ovulation in both the uterine arteries and their branches. It seems that endometrial perfusion presents more accurate noninvasive assay of uterine receptivity than uterine artery perfusion alone. Endometrial receptivity is maximum during the time of peak luteal function during which implantation is most likely to occur. During the pregnancy impedance to blood flow decrease from the main uterine to the spiral arteries as well as with the advancing gestational age. The spiral arteries in pregnancy become the vessels with completely different haemodynamic characteristics in relation to other arteries of uteroplacental circulation. Color Doppler adds new information on perfusion and pathophysiological changes connected with the ectopic trophoblast implantation.

“…The goal of antenatal testing in this setting is early recognition of chorioamnionitis necessitating delivery. Most experts recommend daily antenatal testing in patients with PPROM, either with the NST (69) or the BPP (70). …”

In August 2007, the Eunice Kennedy Shriver National Institute of Child Health and Human Development, the National Institutes of Health Office of Rare Diseases, the American College of Obstetricians and Gynecologists, and the American Academy of Pediatrics cosponsored a 2-day workshop to reassess the body of evidence supporting antepartum assessment of fetal well-being, identify key gaps in the evidence, and formulate recommendations for further research. Participants included experts in obstetrics and fetal physiology, and representatives from relevant stakeholder groups and organizations. This article is a summary of the discussions at the workshop, including synopses of oral presentations on the epidemiology of stillbirth and fetal neurological injury, fetal physiology, techniques for antenatal monitoring, and maternal and fetal indications for monitoring. Finally, a synthesis of recommendations for further research compiled from three breakout workgroups is presented.
