BACKGROUND AND PURPOSE The pathogenesis of cerebral aneurysms still raises some controversies. The aim of this study was to identify morphological, hemodynamic, and clinical independent risk factors for anterior communicating artery (ACoA) aneurysm development. METHODS Computed tomography angiography and transcranial color-coded sonography were performed in 77 patients with a nonbleeding ACoA...

Objectives: Uterine artery Doppler is frequently used in the first trimester and it one of more effective measurement methods prediction preeclampsia intrauterine growth restriction (IUGR). Progesterone a hormone that quite various indications obstetrics gynecologic practice. We aimed to investigate influence progesterone on uterine pulsatility index (PI) at 11–14 gestational weeks. Material me...

To investigate the effects of pulsatile and continuous pediatric ventricular assist (PVAD) flow and pediatric blood viscoelasticity on hemodynamics in a pediatric aortic graft model. Hemodynamic parameters of pulsatility, along with velocity and wall shear stress (WSS), are analyzed and compared between Newtonian and viscoelastic blood models at a range of physiological pediatric hematocrits us...

objective: to compare the effectiveness of letrozole and clomiphene citrate (cc) on uterine blood flow rate in patients with unexplained infertility. materials and methods: in this randomized clinical trial 90 women with unexplained infertility referred to a university clinic from january 2011- december 2013 were enrolled. thirty patients were randomized for letrozole, 30 patients for cc and 3o...

AIM To compare the mean of anteroposterior (AP) measurements of the uterus in longitudinal and oblique transverse planes, and the pulsatility index (PI) and resistive index (RI) of the uterine artery and superficial skin wound artery between patients taking Channa striatus and placebo. BACKGROUND Channa striatus, also known as haruan, is a fresh water snakehead fish consumed in many parts of ...

OBJECTIVE To assess the impact of respiratory therapy with the expiratory flow increase technique on cerebral hemodynamics of premature newborns. METHODS This is an intervention study, which included 40 preterm infants (≤34 weeks) aged 8-15 days of life, clinically stable in ambient air or oxygen catheter use. Children with heart defects, diagnosis of brain lesion and/or those using vasoactiv...
