This study aims to investigate the fetal outcomes and associated factors of adverse pregnancy outcomes (APOs) in pregnant women with systemic lupus erythematosus (SLE). Clinical data from 251 SLE patients with 263 pregnancies from 2001 to 2015 were analyzed retrospectively. APOs occurred in 70.0% of pregnancies, in which pregnancy loss occurred in 28.5%; preterm delivery occurred in 21.3%; intr...
Doppler ultrasound is one of the non-invasive methods for blood flow assessment in cardio-vascular system and celiac trunk as the first branch of abdominal aorta is an important splanchnic artery. According to the relative differences in the reports of normal indices from doppler ultrasound of the celiac artery in the different medical centers of the world, it was decided to evaluate this issue...
background the behcet disease is a multisystemic disease with involvement of vessels. objectives our aim is to evaluate the frequency of carotid artery disease in asymptomatic carotid artery involvement in patients with behcet disease and compare the results with a control group. patients and methods fifty patients with behcet disease who were asymptomatic for any vascular involvement and 50 he...
INTRODUCTION Many abnormalities are observed in the morphology and pathology of the umbilical cord. The aim of the study was to assess the role of 3D sonography in pathology of true umbilical cord knots. MATERIAL AND METHODS In our materials we observed 10 cases of true umbilical cord knots in a population of 2,864 deliveries. The 2-dimensional transverse scan of the umbilical cord was shown ...
background abnormalities in the velocity and pattern of myocardial shortening on tissue doppler imaging (tdi) have been proposed to aid in the noninvasive diagnosis of coronary artery disease (cad). objectives we investigated the diagnostic value of post-systolic shortening (pss), a delayed ejection velocity of the myocardium after the closure of the aortic valve, on tdi in the diagnosis of cad...
SUBJECT This study investigates the placental autophagic activity in growth-restricted fetuses in the monochorionic (MC) twin model. PATIENTS AND METHODS Forty MC twins were prospectively enrolled in this study, including 21 with and 19 without selective intrauterine growth restriction (sIUGR), defined as birth weight below the tenth percentile. The sIUGR group was subdivided on the basis of ...
BACKGROUND The mechanistic basis of the proposed relationship between maternal cardiac output and neonatal complications in pregnant women with heart disease has not been well elucidated. METHODS AND RESULTS Pregnant women with cardiac disease and healthy pregnant women (controls) were prospectively followed with maternal echocardiography and obstetrical ultrasound scans at baseline, third tr...
OBJECTIVES To explore in growth-restricted fetuses the sequence of changes in aortic isthmus and ductus venosus blood flow in relation to other arterial Doppler parameters commonly used to evaluate fetal wellbeing. METHODS Umbilical and middle cerebral arteries, ductus venosus and aortic isthmus were explored serially by means of pulsed Doppler in a cohort of singleton small-for-gestational a...
