Aim: To evaluate uterine artery Doppler flow resistance and plasma adrenomedullin levels in women with unexplained recurrent pregnancy loss (RPL) compared to controls. Material & Methods: Eighty-three women, who attend the department of Obstetrics and Gynecology, Benha University, Egypt, participated in this study (RPL group: n = 40, and control group: n = 43). Uterine artery Doppler and plasma adrenomedullin (AM) (pg/mL) levels were measured for all women in the mid-luteal phase of a non-pregnant cycle. Results: Both uterine artery pulsatility index (PI) and AM levels were significantly higher in RPL group compared to controls (2.71 ± 0.259 vs 2.06 ± 0.194 for PI and 287.5 ± 80.4 pg/mL vs 156.1 ± 39.8 pg/mL for AM, P < 0.01). Uterine artery PI had a significant positive correlation with plasma AM levels both in the RPL group (r = 0.645, P < 0.001) and in the control group (r = 0.384, P = 0.011). Number of previous miscarriages in RPL group was significantly correlated with both uterine artery PI (r = 0.838, P = 0.015) and plasma AM levels (r = 0.509, P = 0.001). Conclusions: Uterine artery PI may be useful in identifying women with unexplained RPL who have impaired uterine circulation. Plasma AM may serve as a biochemical marker for RPL caused by impaired uterine perfusion.

To evaluate the potential value of uterine artery Doppler velocimetry in diagnosing placenta accreta.
To explore if first-trimester uterine artery Doppler velocimetric values might predict adverse perinatal outcomes in patients conceiving via in vitro fertilization (IVF).
We sought to examine flow velocity waveforms of the uterine arteries with respect to placental location at 20-40 weeks' gestation. Blood flow (BF) volume, pulsatility index (PI), resistance index (RI)...
Doppler ultrasonography plays an ever-increasing role in obstetric imaging. Although commonly purported to assess blood flow, most studies in this area report purely on velocimetric parameters, rather...
To study whether fetal main pulmonary artery (MPA) Doppler indices can predict the development of neonatal respiratory distress syndrome (RDS).
The purpose of the present study is to evaluate the occurrence of first trimester bleeding among patients with abnormal uterine artery Doppler. A prospective study is designed and two gro...
The primary objective of this study is to evaluate the safety and effectiveness of Doppler guided Uterine Artery Occlusion (D-UAO) as treatment for the reduction of fibroid-associated symp...
The aim of this study was to evaluate the effect of the LNG-IUS and TCU 380A users on the sub-endometrial vascularization and the uterine artery blood flow using power Doppler analysis and...

A branch arising from the internal iliac artery in females, that supplies blood to the uterus.
The use of embolizing agents to block the arterial blood supply to parts or all of the UTERUS. The procedures are done to control bleeding or to cause destruction of uterine tissues.
Ultrasonography applying the Doppler effect combined with real-time imaging. The real-time image is created by rapid movement of the ultrasound beam. A powerful advantage of this technique is the ability to estimate the velocity of flow from the Doppler shift frequency.
A 52-amino acid peptide with multi-functions. It was originally isolated from PHEOCHROMOCYTOMA and ADRENAL MEDULLA but is widely distributed throughout the body including lung and kidney tissues. Besides controlling fluid-electrolyte homeostasis, adrenomedullin is a potent vasodilator and can inhibit pituitary ACTH secretion.
Echocardiography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
