The aim of the present study was to evaluate uterine blood flow (UBF) during the postpartum period in small ruminants. The study involved measures of UBF in 5 ewes and 5 goats during the first 4 weeks after parturition. Transrectal quantification of UBF was assessed by determining the diameter (DM), time averaged mean velocity (TAMEAN), blood flow volume (BFV), blood flow acceleration (ACCE) and pulsatility index (PI) in the uterine arteries ipsilateral to the previously gravid uterine horn(s) at Wk 20 of gestation and every 3days from the day of parturition (D 0) until Day 27 postpartum (D 27)...

This study evaluated the effect of mycophenolate mofetil (MMF) on uterine tissue preservation following ischaemia/reperfusion (I/R) injury. Uterine I/R injury was induced in rats by clamping the lower abdominal aorta and ovarian arteries for 30 min. Group I/R + V (n = 7) received vehicle alone while Group I/R + M (n = 7) received 20 mg/kg/day MMF. Control groups underwent sham surgery and received vehicle (Group C) or 20 mg/kg/day MMF (Group M) (n = 7 for both). Four hours after detorsion, uterine tissue 8-hydroxy-2'-deoxyguanosine (8-OHdG), glutathione, malondialdehyde (MDA), myeloperoxidase (MPO), superoxide dismutase (SOD) and serum ischaemia modified albumin (IMA) concentrations were measured...

Autoantibodies to the angiotensin II (ANGII) type I receptor (AT1-AA) are associated with preeclampsia (PE). We found that Vitamin D supplementation reduced AT1-AA and blood pressure (MAP) in the RUPP rat model of PE. However, it was undetermined if the decrease in AT1-AA was the mechanism whereby Vitamin D lowered MAP or if it was through factors downstream of AT1-AA. Uterine artery resistance index, placental ET-1 and sFlt-1 are increased with AT1-AA induced hypertension and considered markers of PE in pregnant women...

The objective of this study was to investigate the effects of supplementing dried distillers' grains plus solubles (DDGS) during late gestation on uterine blood flow (BF), circulating steroid hormones and hepatic steroid metabolizing enzymes, and calf and placental weights. Multiparous beef cows were randomly divided into a control group (CON; = 15) consuming a diet containing 90% corn stover and 10% corn silage (DM basis) for ad libitum intake and a treatment group (SUP; = 12) consuming the same diet and DDGS (0...

The incidence of uterine arteriovenous malformation (AVM) is rare. However, it is clinically significant in that it can cause life-threatening vaginal bleeding. We report a case of a large uterine AVM with positive serum beta-human chorionic gonadotropin. A presumptive diagnosis was made; a uterine AVM accompanied by, early pregnancy or retained product of conception. Because this uterine AVM was extensive, transcatheter arterial embolization of both uterine arteries and extra-uterine feeding arteries was performed...

OBJECTIVE: To investigate whether the uterine artery pulsatility index (UtA PI) of hypertensive pregnancies is higher than that of normal pregnancies in the puerperium, as well as in the antepartum period. METHODS: The UtA PI was measured in hypertensive (group 1) and normal pregnancies (group 2) during antepartum, immediate postpartum or late postpartum periods. Using the transvaginal approach, the bilateral uterine artery indices were measured. RESULTS: One hundred twenty-two women were enrolled: group 1, hypertensive disease in pregnancy (11 cases in antepartum, 13 cases in immediate postpartum and 10 cases in late postpartum period); group 2, normal pregnancies (32 cases in antepartum, 29 cases in immediate postpartum and 27 cases in late postpartum)...

We report a case of uterine artery rupture in a woman at 14 weeks' gestation who presented with abdominal pain, tachycardia, and hypotension and underwent a diagnostic laparoscopy. During this procedure, a spontaneous rupture of the left uterine artery was diagnosed and the surgery was converted into a laparotomy. The artery was bound to its origin and to its distal uterine portion. The patient exhibited excellent postoperative recovery and was discharged two days after the surgery. The pregnancy continued without other maternal or fetal complications, and the patient delivered a healthy newborn via cesarean section at 39 weeks of gestation...

BACKGROUND: Prenatal events such as intrauterine growth restriction can affect gonadal development of the offspring and have an impact on reproductive health. PURPOSE: To investigate the effects of intrauterine growth restricted induced by uterine artery ligation on the postnatal rat testis. METHODS: Pregnant rats underwent uterine artery ligation at day 19 of gestation. Offspring were sacrificed at 5, 20 and 40 days post-partum (dpp). At sacrifice, one gonad was snap frozen in liquid nitrogen and processed for RNA and steroid extraction...

PURPOSE: To assess efficacy of two different techniques of lidocaine injection in the uterine arteries to reduce pain following uterine artery embolization (UAE) for leiomyomas. MATERIALS AND METHODS: This prospective randomized single-blinded study was performed with 60 patients enrolled between November 2014 and December 2015 equally randomized to 3 arms. Group A received 10 mL lidocaine 1% (100 mg) mixed with polyvinyl alcohol particles (355-500 μm). Group B received the same dose of lidocaine injected after embolization...

OBJECTIVES: A high ratio of soluble fms-like tyrosine kinase-1 (sFlt-1) to placental growth factor (PlGF) has been linked with pre-eclampsia (PE). We evaluated the sFlt-1/PlGF ratio as a predictive marker for early-onset PE in women at risk of PE. METHODS: This prospective, Spanish, multicenter study included pregnant women with PE risk factors (including: history of intrauterine growth restriction; PE; eclampsia; hemolysis, elevated liver enzymes and low platelet count syndrome; pre-gestational diabetes; and abnormal uterine artery Doppler ultrasound)...

Intrauterine growth restriction (IUGR) increases the incidence of adult cardiovascular disease (CVD). The sex-specific developmental mechanisms for IUGR-induced and western high fat diet (HFD) modification of CVD remain poorly understood. We hypothesized a maternal HFD in the Sprague-Dawley rat would augment IUGR-induced CVD in the offspring through decreased cardiac function and increased extracellular matrix (ECM) remodeling and stiffness in a sex-specific manner. HFD or regular diet (Reg) was given from 5 weeks prior to mating through postnatal day 21 (PND21)...

BACKGROUND: Uterine fibroid embolization (UFE) is an effective minimally invasive treatment aimed to obtain complete fibroid infarction. PURPOSE: To evaluate the degree of fibroid infarction after embolization with acrylamido polyvinyl alcohol microspheres (Bead Block). MATERIAL AND METHODS: This prospective study included 26 pre-menopausal women in the period October 2013 to January 2015. UFE with the use of Bead Block microspheres 700-900 µm was obtained until flow stasis was achieved...

PURPOSE: To investigate the relationship between maternal copeptin levels and uterine artery Doppler examination and progress of preeclampsia. MATERIALS AND METHODS: A cross-sectional study was designed with women those were screened at 20 + 0 - 24 + 6 weeks' gestation between May 2014 and August 2014. The obstetric records of all normotensive women were examined. Uterine artery Doppler velocimetry results and serum copeptin levels were measured. The patients were divided in two groups according to normal (n = 67) and abnormal uterine artery Doppler (n = 21) findings...

BACKGROUND: It has been suggested that an inadequate blood supply caused by uterine fibroids may lead to decreasing fertility. Therefore, a quantitative evaluation of blood flow in the uterus might be a good tool for infertility treatments. For the first step, the ability to perform arterial spin labeling (ASL)-MRI in pelvic organs was examined by measuring blood flow in the uterine muscle layer. RESULTS: Three normal volunteer women, seven patients with one uterine fibroid and four patients treated with GnRH analogue for uterine fibroids, were enrolled in this study...

OBJECTIVES: The primary aim of the study was to assess intra-observer and inter-observer reproducibility and generalizability (general reliability) of first trimester Doppler measurements of uterine arteries (UtA) performed both transabdominally (TA) and transvaginally (TV). Secondary aims were to investigate whether maternal BMI and acquisition modality (transabdominal or transvaginal) affect feasibility and reliability of UtA Doppler evaluation. METHODS: Singleton pregnancies between 11(+0) and 13(+6) weeks underwent TA and TV Doppler measurements of UtA prospectively, blindly and independently by Fetal Medicine Foundation-accredited operators...
