84
Advanced maternal age ?
Considered over > 35 years old

85
Three main procedures used to obtain fetal karyotyping ?
CVS / Chorionic Villus Sampling
Amniocentesis
Cordocentesis
86
Chorionic Villus Sampling ?
Obtained during pregnancy for karyotyping
Done between 10 and 13 weeks — under sonographic guidance ;
A needle or a plastic catheter is placed within the placenta to obtain a sample of trophoblastic cells
(When the procedure is performed before 10 weeks there is speculations of it being linked to fetal limb abnormalities)
87
Amniocentesis?
Used for genetic purposes between 15 and 20 weeks
(Procedure done before 15 weeks has been linked to increase in fetal complications)
Procedure is done Transabdominally with sonographic guidance while a needle is inserted into the abdomen into the amniotic sac to remove amniotic fluid sample for testing
Most common side effect is uterine contractions and cramping.
Can take as long as 3 weeks for a complete analysis of the fluid
Also can be done to assess lung maturity by assessing the L : S. Ratio (lecithin to sphingomyelin)
88
Therapeutic Amniocentesis ?
Can be peformed to aspirate and relieve the patients from polyhydramnios or can be used to distend the amniotic cavity with more fluid when oligohydramnios is present
89
Cordocentesis ?
Percutaneous umbilical cord sampling (PUBS)
Fetal blood sampling from a needle being sonographically guided transabdominal through the maternal abdomen, into the umbilical cord near the insertion site of the cord to the placenta (umbilical vein)
Can lead to fetal bradycardia and hemorrhage at the sampling site
PUBS allows for rapid detection rate of less than 72 hours for results and detection of chromosomal anomalies
Carries a higher fetal loss rate than amniocentesis
