Background: The ductus venosus (DV) transports oxygenated blood to the developing heart and brain by avoiding hepatic circulation. Due anatomical location of DV, measurement DV flow velocity waveforms indirectly disclose cardiac functions health foetus, which represents pressure gradient between umbilical vein right atrium. aim this study was evaluate value pulstality index veins in early pregn...
Interruption of the aortic arch is a rare and usually lethal congenital anomaly that is often associated with multiple cardiac malformations. Most neonates with aortic arch interruption perish once the ductus arteriosus closes after birth. However, sporadic cases have been reported to survive into adulthood uneventfully. Here, we report a 19-year-old male with a 3-month history of exertional dy...
Effective screening for major aneuploidies can be provided in the first trimester of pregnancy. Screening by a combination of fetal nuchal translucency and maternal serum free-β-human chorionic gonadotrophin and pregnancy-associated plasma protein-A can identify about 90% of fetuses with trisomy 21 and other major aneuploidies for a false-positive rate of 5%. Improvement in the performance of f...
The discovery of a large patent ductus venosus resulted from radiological investigations in a 34-year-old man, a chronic alcoholic of low mental status. Splenoportal and inferior caval venograms were performed because of recent exacerbation of the neurological symptoms and electroencephalographic criteria of portacaval encephalopathy. Portal pressure was 8 mm Hg. A liver scan, a laparoscopy, an...
BACKGROUND Absent ductus venosus (ADV) is a rare condition, but it should be known that this embryonic anomaly may be detected by fetal echocardiographic or newborn ultrasound examinations. CASE REPORT We present a baby with an ADV and an accompanying alternative porto-caval shunt between the right portal vein and inferior vena cava detected on postnatal ultrasound examination. CONCLUSIONS ...
