Fetomaternal transfusion after amniocentesis and cordocentesis

“…Procedural time Longer procedural time was observed for CC than for AC. The literature data indicate that a longer procedural time is accompanied by a higher degree of FMT [5,12]. 2.…”

“…Both AC and CC are frequently accompanied by fetomaternal transfusion (FMT) [5,[10][11][12][13]. Fetomaternal transfusion may influence the pregnancy outcome by inducing unwanted fetal loss [10,14,15] and maternal rhesus isoimmunization with subsequent fetal erythroblastosis [16][17][18].…”
