I'm 40; my partner is 50. This is our first pregnancy. We are very concerned about age-related risk of chromosomal abnormalities, but opted against CVS and then amnio when 1st trimester screening adjusted our background trisomy 21 risk to 1:272 and trisomy 13/18 risk to 1:843.
I am above average height (183 cm) and the father is below average height (168 cm). My question is this: at 21 weeks + 3 (dated by known LMP), the femur length of the fetus is 33.5 mm. (Other measurements taken at the same time include BPD 53 mm; HC 182 mm; TCD 21 mm; CM 5 mm and AC 161 mm.) Is this low enough to warrant concern? Urgently seeking advice. Any comments would be gratefully received. Thanks very much.

I just went thru a trisomy 18 scare myself and had a level 2 sono I am not sure about the femur length but when they check they look at alot of things and if that is the only concern you should be fine...but you should really talk to your doctor about this and I wish you good luck as with my scare that was all it was my baby was found to be perfectly healthy as I am sure yours will be again good luck
