Venous hemodynamics and volume homeostasis are important aspects of cardiovascular physiology, however today their relevance is still very much underappreciated. Their most important role is maintenance and control of venous return and as such cardiac output. A high flow/low resistance circulation, remaining constant under physiological circumstances, is mandatory for an uncomplicated course of pregnancy. In this paper, characteristics of normal and abnormal venous and volume regulating functions are discussed with respect to normal and pathologic outcomes of pregnancy, and current (non-invasive) methods to assess these functions are summarized...

OBJECTIVES: Preterm birth (PTB) is more common among in-vitro fertilization (IVF) as compared to natural conception. However, the extent to which this it due to spontaneous labour or to iatrogenic indications has not been determined. This study quantifies the risk of spontaneous preterm birth (SPTB) in singleton pregnancies resulting from IVF as compared to spontaneous conception. METHODS: Web-based databases search (PubMed/Medline, Scopus, Web of Science) up to September 2017 identified articles comparing the risk of SPTB in singleton IVF/ICSI and naturally conceived pregnancies...

Prenatal diagnostic methods and screening procedures change rapidly in these years. Years ago only karyotyping was performed prenatally, and we monitored only Down syndrome(1) . Since then the diagnostic possibilities have increased to QF-PCR, FISH, MLPA and chromosomal microarray.

A 27-year-old woman with a previous right oophorectomy for dysgerminoma diagnosed 9 years earlier, was referred to our center after the incidental finding of a left ovarian mass and increased ß-hCG levels (22.000 IU/mL). At ultrasound examination, a solid lesion of 34x23x38 mm in size, was detected in the left ovary and it appeared as a mass with an inhomogeneous echotexture, irregular contour and no stripy echogenicity (Figure 1a, Suppl 1). An ovarian crescent sign was clearly visualized at the lateral part of the left mass...

Giant chorioangioma (>4cm) is a rare placental tumour associated with adverse pregnancy outcome including polyhydramnios, fetal anaemia, cardiomegaly, hydrops and increased perinatal mortality (1). Prenatal therapy may be performed when there are ultrasound features of fetal compromise and the gestation is non-viable. Therapeutic interventions include direct injection of various chemicals and laser coagulation on tumour's feeding vessels (2, 3).

INTRODUCTION: As birth weight is a critical predictor of neonatal congenital heart defect (CHD) outcomes, the common problem of poor fetal growth in this population is clinically important but not well understood. The impact of fetal hemodynamics on fetal growth and birth weight in CHD has not been assessed. Combined cardiac output (CCO) has been used to evaluate patients with structurally normal heart but rarely in CHD. Middle cerebral artery and umbilical artery pulsatility indices (PIs) have been used to evaluate the relative distribution of circulation in patients with CHD...

A tumor obstructing the fetal upper airway including oral cavity is a life-threatening condition that warrants a careful planning of delivery involving a multidisciplinary team and the possibility of performing an EXIT (Ex-Utero Intrapartum Therapy) surgery to secure the newborn's airway by complex procedures such as direct laryngoscopy, bronchoscopy, tracheostomy, cyst decompression and tumor resection(1) . Once a cervical or oral tumor is identified a thorough fetal ultrasound examination is performed to rule out other significant anomalies and determine the characteristics of the tumor (solid or fluid), the degree of infiltration into adjacent structures and the mass effect that might produce in the fetal airway...
