[Sampling fetal blood from the umbilical cord under echographic guidance].
The performance of 465 sonographically guided percutaneous umbilical blood samplings and its use in the management of diagnostic problems in the second and third trimester of pregnancy are described. The method has been employed in the prenatal assessment of 423 patients (357 procedures in the second trimester and 108 in the third trimester). Pure fetal blood was obtained in all third trimester samplings whilst in the second trimester in 4 cases (1.1%) fetal blood could not be obtained at the first procedure and in 9 cases (2.6%) contamination with maternal blood or amniotic fluid was observed. Data analysis confirm how this simple and rapid procedure offers access to the fetal circulation for diagnostic and therapeutic purposes.
