While the contractile effect of oxytocin on uterine artery has been reported, little is known about whether pregnancy affects the responsiveness of this artery to oxytocin. If it does, is it a consequence of changed endothelial function, as has been proposed for some other vasoconstrictors. Furthermore, the receptor subtypes involved in oxytocin action on uterine artery has not been yet determi...

A 30-year-old woman experienced severe abdominal pain 8 days after vaginal delivery. The patient was diagnosed with hemoperitoneum due to rupture of the left uterine artery pseudoaneurysm, which was confirmed via ultrasound with color Doppler and computed tomography scans. This patient was treated with bilateral uterine artery embolization to maintain fertility. A uterine artery pseudoaneurysm ...

OBJECTIVE To determine whether placental laterality and discordant uterine artery impedance during pregnancy is a random event or the result of uterine artery pathology. METHODS We identified 50 patients with unilateral placenta and pathologic uterine artery impedance during their current pregnancy and enrolled them in the study. Thirty-three of these patients met the inclusion criteria and r...

background:   objective: to determine and compare uteroplacental circulation and obstetrics complications in pregnant women with pcos treated with metformin, aspirin and control group.   materials and methods: 105 pregnant women with pcos were enrolled in this study after assessing uterine artery pulsatility index (pi) with doppler ultrasonography at 12 weeks of gestation. the patients were div...

Background Fetal growth restriction is the second leading cause of perinatal morbidity and mortality. The incidence of intrauterine growth restriction (IUGR) is estimated to be approximately 5 percent in the general obstetric population. Abnormal uterine artery suggest a maternal cause for the growth restriction where as normal uterine artery Doppler studies suggest that a fetal cause. Use of u...

PURPOSE OF REVIEW The management of uterine fibroids in patients requiring treatment who desire future fertility remains controversial. Myomectomy has been the most common operative procedure to improve pregnancy rates and outcomes. Uterine fibroid embolization is an increasingly popular, minimally invasive treatment for fibroids. This review aims to provide critical analysis of available data ...

Uterine artery embolization as a therapeutic method in fibromyoma requires a good knowledge of the origin of the uterine artery to the success of this procedure involving selective catheterization. This study presents a classification of anatomical variants of uterine artery as a retrospective review of consecutive arteriogram, complete with various aspects of the origin of the uterine artery i...

Uterine artery embolization (UAE) is a minimal invasive technique that uses transcutaneous common femoral artery approach to block uterine blood supply. The aim of the procedure is to occlude or markedly reduce blood flow in both uterine arteries at the arteriolar level. This causes irreversible ischemia and leads to necrosis and subsequent shrinkage of uterine myomas. In current clinical pract...

BACKGROUND Uterine artery pseudoaneurysm (UAP) normally presents genital bleeding in the puerperal period, and severe hydronephrosis rarely presents during pregnancy. We report a rare case of severe ureteral obstruction accompanied by uterine artery pseudoaneurysm in the early second trimester of pregnancy, which was successfully treated by surgical intervention. CASE PRESENTATION A 42-year-o...

background: uterine natural killer (unk) cells are the most abundant leukocytes in pre-implantation endometrium and early pregnancy deciduas in humans and rodents. they are associated with structural changes in maternal spiral arteries but regulation of their re-cruitment and activation is incompletely understood. the major subpopulation of unk cells in humans expresses cd56, the neural cell ad...
