Fetal intraabdominal umbilical vein varix (FIUV) is focal dilatation of the intrabdominalumbilical vein of thefetus. It appears as a round or fusiform cystic structure in thefetal abdomen, which shows continuity with the umbilical vein ongrayscale andcolor Dopplerimaging. The diagnostic criteria include the FIUV varix diameter at least 50% wider than the diameter of the intrahepatic umbilical v...

Postnatal examination of fetal appendages is important because this information may help predict perinatal outcome. We present a case of a red streak along the entire umbilical vein after a cesarean section due to non-reassuring fetal status. The pathological findings revealed an umbilical cord with dilated vascular changes and mild funisitis. Because the dilated change was intense in the umbil...

Spontaneous external hemorrhage from an umbilical varix is rare. We describe a 40-year-old man with cirrhosis and portal hypertension, who presented with recurrent external bleeding from an umbilical varix. The first episode was controlled by transfixation of the vein under local anesthesia. Contrast-enhanced CT scan demonstrated a hugely distended recanalized umbilical vein arising from the le...

Congenital absence of portal vein (CAPV) is a rare abnormality, which may be associated with other abnormalities. We report a case of prenatal diagnosis of absent portal vein confirmed on postnatal ultrasonography and computed tomography scan. The ultrasound features of CAPV include dilated intra-abdominal segment of umbilical vein, dilated inferior vena cava and the presence of hyperechogenic ...

The umbilical cord is a helical and tubular blood conduit connecting the foetus to the placenta. The umbilical cord achieves its final form by the 12th week of gestation and normally contains two arteries and a single vein, all embedded in Wharton's jelly. The structure of the umbilical cord receives only a cursory glance during many obstetric ultrasound examinations: with imaging limited to do...

Malta Medical Journal Volume 21 Issue 01 March 2009 Abstract A healthy female infant was found to have two umbilical arteries and two umbilical veins at the cut surface of the cord at birth. Detailed inspection of the cord showed the second vein to represent a short segment vestigial vessel that, moreover, was not associated with any other congenital anomaly as is often found in infants with um...

A 59-year-old woman known to have micronodular cirrhosis presented with haemorrhage from the umbilicus. She eventually required exomphalectomy at which a huge patent umbilical vein was found and ligated. Selective coeliac and superior mesenteric angiography with late phase films confirmed a large umbilical vein filling from the left branch of the portal vein. So far as the author knows, umbilic...

Vinyl catheters were inserted into an umbilical vein, a hindlimb vein and either an umbilical or dorsalis pedis artery in 9 lamb fetuses with gestational ages of 110 to 147 days. The lambs were then delivered from the uterus, but placental flow was maintained. Cannulating electromagnetic flow transducers were inserted into both umbilical veins. Antipyrine solution was constantly infused into th...

OBJECTIVES The morphology of region umbilical vein, umbilical sinus and ductus venosus of human fetuses have been investigated. MATERIAL AND METHODS 26 human fetuses between 20 and 40 weeks' gestation were examined by morphological methods. The umbilical vein, DV and the portal vein were obtained after termination of gestation. Tissue samples have been fixed in phormaldehyde solution (pH 7,2)...

OBJECTIVE This study aimed to compare the therapeutic efficacy of transplantation of human umbilical cord mesenchymal stem cells (hUCMSC) in different routes in acute hepatic failure (ALF) in rats. METHODS hUCMSCs were isolated and identified by detection of surface antigens via flow cytometry. In T group and H group, ALF rats received hUCMSC transplantation through the tail vein and intrahep...
