OBJECTIVE: Early diagnosis of significant patent ductus arteriosus reduces the risk of clinical worsening in very low birth weight infants. Echocardiographic patent ductus arteriosus shunt flow pattern can be used to predict significant patent ductus arteriosus. Pulmonary venous flow, expressed as vein velocity time integral, is correlated to ductus arteriosus closure. The aim of this study is to investigate the relationship between significant reductions in vein velocity time integral and non-significant patent ductus arteriosus in the first week of life...

Lymphoscintigraphy is not considered as a first line diagnostic procedure in abdominal or thoracic lymphorrhea of various origin. We report a patient with lymphangiectasia in whom posttraumatic lymphorrhea was diagnosed by lymphoscintigraphy only after third attempt when we applied pushups exercise with the aim to raise venous pressure and thus provoke lymph backflow in ductus thoracicus and enteric lymphytics. Lymphorrhea was clearly visible in colon ascendens and colon transversum on 9h planar scintigram...

The standard technique of catheter closure of patent ductus arteriosus (PDA) may be associated with arterial complications particularly in small pediatric patients. The aim of this study was to evaluate whether catheter closure of PDA in small children using an exclusive venous approach is a safe and effective alternative to closure with the standard technique. One hundred-twelve patients, aged 2 to 24 months, were randomly assigned in a 1:1 ratio to catheter closure of PDA using the standard technique (group 1) and an exclusive venous approach (group 2), respectively...

Total anomalous pulmonary venous connection (TAPVC) is a rare congenital anomaly of the pulmonary veins drainage. In this entity, the pulmonary veins, instead of draining to left atrium, connect abnormally to the systemic venous circulation. A right-to-left shunt is obligatory for survival. Based on its type and degree of pulmonary venous obstruction, TAPVC may result in pulmonary hypertension and congestive heart failure. In severe cases, urgent diagnosis and surgical correction is essential to reduce morbidity and mortality...

BACKGROUND: Erythropoietin seems to play an important role in the regulation of fetal hypoxemia. The present prospective study was designed to determine if changes in erythropoietin levels can be found in fetuses with severe early-onset growth restriction and hemodynamic compromise. METHODS AND RESULTS: Erythropoietin, hemoglobin, hematocrit, platelet counts, normoblasts, lacate, arterial and venous blood gasses in the umbilical cord were determined in 42 fetuses with fetal growth restriction (IUGR) with absent (zero-flow) and 26 IUGR fetuses with retrograde end-diastolic flow (reverse-flow) in the umbilical artery...

OBJECTIVES: To explore if in early fetal growth restriction (FGR) the longitudinal pattern of short-term fetal heart rate (FHR) variation (STV) can be used for identifying imminent fetal distress and if abnormalities of FHR registration associate with two-year infant outcome. METHODS: The original TRUFFLE study assessed if in early FGR the use of ductus venosus Doppler pulsatility index (DVPI), in combination with a safety-net of very low STV and / or recurrent decelerations, could improve two-year infant survival without neurological impairment in comparison to computerised cardiotocography (cCTG) with STV calculation only...

INTRODUCTION: Human type 1 diabetic pregnancy is associated with placental structural and hemodynamic abnormalities. We hypothesized that in rat fetuses of hyperglycemic dams, placental and fetal blood flow velocity waveforms demonstrate compromised hemodynamics when compared to control fetuses, and these hemodynamic parameters correlate with placental structural abnormalities at near term gestation. METHODS: Streptozotocin-induced maternal hyperglycemia group comprised 10 dams with 107 fetuses and the control group 20 dams with 219 fetuses...

: Introduction Ibuprofen is used widely to close patent ductus arteriosus in preterm infants. The anti-inflammatory activity of ibuprofen may also be partly due to its ability to scavenge reactive oxygen species and reactive nitrogen species. We evaluated the interaction between oxidative status and the medical treatment of patent ductus arteriosus with two forms of ibuprofen. Materials and methods This study enrolled newborns of gestational age ⩽32 weeks, birth weight ⩽1500 g, and postnatal age 48-96 hours, who received either intravenous or oral ibuprofen to treat patent ductus arteriosus...

Introduction Congenital umbilical arteriovenous malformations (AVMs) are extremely rare. We present the first case of congenital umbilical AVM with feeding arteries originating not only from abdominal but also from the mammary arteries. Case Report A 34-week gestational age newborn was transferred to our hospital with a supraumbilical murmur. Abdominal Doppler ultrasound (US) showed a large vascular AVM, with multiple feeding arteries and several venous drainage structures to the umbilical vein and also a persistent ductus venosus...

Pulmonary sequestration is an unusual cause of heart failure in infants. We report a preterm newborn with signs of congestive heart failure supposed secondary to a ductus arteriosus that was finally diagnosed as a coexistent extralobar pulmonary sequestration. In this case, Doppler echocardiography was essential for diagnosis, revealing an abnormal systemic arterial supply to the sequestered lung and abnormal venous drainage.

The aim of this prospective study was to determine the frequency and composition of cerebral microemboli in a pediatric population, during transcatheter closure of patent ductus arteriosus (PDA). Multifrequency transcranial Doppler was used to monitor cerebral blood flow velocity (CBFV) and detect microembolic signals (MES) in the middle cerebral artery in 23 patients (median age 18 months). MES were automatically identified and differentiated according to composition; gaseous or solid. The procedure was divided into five periods: Arterial catheterization; venous catheterization; ductal catheterization; angiography; device placement and release...

Coronary-cameral fistulas (CCF) are anomalous connections between one or more coronary arteries and a cardiac chamber, most commonly the right ventricle or right atrium. The major indications for closure are: significant left to right shunt, myocardial ischaemia, prevention of endoarteritis or rupture. Nowadays, the first option for treatment is transcatheter closure. According to the morphology of the fistulas the most appropriate occluder device should be selected: coils (e.g., Gianturco coils, controlled-release coils, PFM coils), vascular plugs or a patent ductus arteriosus (PDA) device or muscular ventricular septal defect (VSD) device...

Congenital heart defects (CHD) affect approximately 7% of infants, and account for 3% of all infant deaths. CHD is most often caused by the defects associated with ductus arteriosus, which is a vessel that usually closes shortly after birth. The types of CHD include tetralogy of fallot, hypoplastic left heart syndrome, pulmonary atresia, total anomalous pulmonary venous return, transposition of great arteries, tricuspid atresia and truncus arteriosus. There are some risk factors that can increase the chance of a fetus developing CHD such as prematurity, an existing CHD in a first-degree relative, genetic syndromes, infections in utero, maternal drug consumptions and disorders...

BACKGROUND: Preterm birth remains the major risk factor for the development of intraventricular haemorrhage, an injury that occurs in 25% of very low birth weight infants. Intraventricular haemorrhage is thought to be venous in origin and intrinsic thromboses in the germinal matrix are likely to play a triggering role. Heparin activates antithrombin and promotes the inactivation of thrombin and other target proteinases. The administration of anticoagulants such as heparin may offset the increased risk of developing intraventricular haemorrhage and may also reduce the risk of developing parenchymal venous infarct, a condition known to complicate intraventricular haemorrhage...

Hepatic complications of malposition of umbilical venous catheter (UVC) are uncommon and occur due to extravasation of hypertonic fluids and the blood products in the liver tissue. Various hepatic complications include thrombosis of hepatic vessels, hepatic necrosis, hepatic fluid collections, and hematoma, with the intraparenchymal liver lesions seen along the course of ductus venosus. Radiologists must be aware of these complications and their imaging findings, as the timely recognition and immediate management can prevent the fatal outcome...

In this study, we present the case of a neonate with obstructed infracardiac total anomalous pulmonary venous connection with severe pulmonary hypertension and a patent ductus arteriosus with right-to-left shunting. The patient had an unusual finding of pandiastolic flow reversal in the upper descending thoracic aorta. He underwent emergency surgical re-routing of the pulmonary veins to the left atrium, and postoperative echocardiography showed disappearance of the descending aortic flow reversal. We hypothesise that in severely obstructed total anomalous pulmonary venous connection the left ventricular output may be extremely low, resulting in flow reversal in the descending aorta...
