BACKGROUND Uterine arteriovenous malformation is a rare but potential life-threatening source of bleeding. A high index of suspicion and accurate diagnosis of the condition in a timely manor are essential because instrumentation that is often used for other sources of uterine bleeding can be lead to massive hemorrhage. CASE We describe here a case of uterine arteriovenous malformation. A 32-y...

Objectives: To study the uterine artery resistance and pulsation indices during the mid luteal phase in patients with history of unexplained recurrent pregnancy loss and the effects of the nitric oxide donor isosorbid mononitrite on these indices. Study Design: A cross-section, controlled observational study. Setting: Benha University Hospital, Egypt. July 2009 to July 2010. Subjects and Method...

BACKGROUND We aimed to evaluate the effect of the levonorgestrel-releasing intrauterine system (LNG-IUS) on the uterine vasculature and the endometrium. METHODS The study was a prospective controlled study evaluating the local effects of LNG-IUS compared with the copper intrauterine device (IUD). Forty-seven women carrying LNG-IUS (group A) were compared with 35 women carrying copper IUD in a...

OBJECTIVE We hypothesised that among nulliparous women with pre-eclampsia, overweight or obese women would have a different phenotype of pre-eclampsia compared with normal weight women with pre-eclampsia. Specifically, they are more likely to develop term pre-eclampsia and less likely to have indicators of impaired placental perfusion, e.g. abnormal uterine artery Doppler or a small-for-gestati...

OBJECTIVES The purpose of this study was to compare the use of vascular indices derived from the whole placenta to those from the placental bed only for predicting preeclampsia and to determine whether the addition of pregnancy-associated plasma protein A (PAPP-A) and mean uterine artery Doppler values improves prediction. METHODS We conducted a secondary analysis of a prospective cohort of w...

BACKGROUND During labor, ephedrine is widely used to prevent or to treat maternal arterial hypotension and restore uterine perfusion pressure to avoid intrapartum fetal asphyxia. However, the effects of ephedrine on uterine blood flow have not been studied during uterine contractions. The purpose of the study was to assess the effects of ephedrine on uterine artery velocities and resistance ind...

OBJECTIVES To investigate the optimal definition of abnormal first-trimester uterine artery Doppler parameters associated with adverse pregnancy outcomes. METHODS A prospective cohort of women with singleton gestations between 11 and 14 weeks consented to uterine artery Doppler measurements. Doppler parameters were measured bilaterally, and mean pulsatility index (PI) and resistive index (RI)...

OBJECTIVE To investigate the value of maternal serum placental protein 13 (PP-13) measurement and uterine artery Doppler during first-trimester screening in the prediction of early pre-eclampsia. METHODS This was a nested case-control prospective study of pregnancies at 11 + 0 to 13 + 6 weeks of gestation. The pulsatility index (PI) of blood flow in the uterine arteries and the maternal serum...

BACKGROUND Ultrasonography has been extensively used in women suspected of having a gynecological malignancy. The aim of this study is to evaluate the efficacy of 3D ultrasonography and power Doppler for discrimination between benign and malignant endometrium in premenopausal women with abnormal uterine bleeding. METHODS This cross-sectional study included 78 premenopausal women with abnormal...

PURPOSE The goal of the present study was to establish new Doppler reference ranges for maternal heart rate, intensity-weighted mean blood flow velocities (Vmean) and impedance indices (PI, RI) for the uterine artery by automated waveform analysis. MATERIALS AND METHODS A cross-sectional prospective study of 921 low-risk pregnancies was performed at 18 - 42 weeks of gestation. Uterine blood f...
