Abstract:
Objective To compare success and complication rate of cordocentesis (CC) with intrahepatic umbilical vein sampling (IUVS) under the guidance of ultrasonography in ovine fetus. Methods Twenty near-term singleton pregnant ewes were randomly divided into CC group and IUVS group (each n=10). All of the ewes underwent CC or IUVS in ovine fetus guided with ultrasonography. Success and complication rate of CC and IUVS were calculated. Results Success rates of IUVS on the first, less than 3 times and 5 times attempt was 32.00%, 68.00% and 84.00%, respectively, higher than that of CC (15.00%, 40.00% and 75.00%, respectively, P<0.05). Sever complication rates of IUVS in comparison with CC was not statistically different (P>0.05). Conclusion Fetal IUVS may be a reasonable option to obtain fetal intravascular access and facilitate therapeutic intervention.
