Isolated single umbilical artery and fetal karyotype.
OBJECTIVE To determine the need for fetal karyotyping in cases of an isolated single umbilical artery (SUA) identified during the second-trimester routine anomaly scan. METHODS All patients booked for antenatal care and delivery in our hospital are offered two ultrasound scans in pregnancy, one at 11-13 weeks' gestation as part of screening for chromosomal defects and another at 20-23 weeks f...
متن کاملAnomalous iliac compliance in children with a single umbilical artery.
Arterial compliance (C) has been measured in 18 children known to have had a single umbilical artery at birth. Non-invasive ultrasonic Doppler techniques were used to measure C for the aorta, iliac, and leg arteries. Anomalous compliance was found between the two iliac vessels, and it is suggested that this is the result of haemodynamic stress-induced changes during development. The demonstrati...

متن کاملDifferent Angiogenic Potentials of Mesenchymal Stem Cells Derived from Umbilical Artery, Umbilical Vein, and Wharton's Jelly
Human mesenchymal stem cells derived from the umbilical cord (UC) are a favorable source for allogeneic cell therapy. Here, we successfully isolated the stem cells derived from three different compartments of the human UC, including perivascular stem cells derived from umbilical arteries (UCA-PSCs), perivascular stem cells derived from umbilical vein (UCV-PSCs), and mesenchymal stem cells deriv...
متن کاملAnomalies associated with single umbilical artery at perinatal autopsy.
We evaluated 214 fetuses sent for autopsy with gestational ages ranging from 12 to 39 weeks. Of these, seventeen fetuses (7.9%) had single umbilical artery. Thirteen of these fetuses were aborted after antenatal detection of severe malformations and 4 died in utero. Genito-urinary system (n=6) and central nervous system (n=4) were the most common sites of involvement. Presence of single umbilic...
