Q

Pathophysiology of HTN in pregnancy

A

The placenta fails to invade properly to the level of the spiral arterioles leading to a high resistance placenta

This causes the release of vasculoendothelial substances from the placenta that causes multi-organ problems for the mother

The hormonal consequences result in generalised vasoconstriction. At the same time, endothelial cell damage causes interstitial leakage through which blood constituents, including platelets and fibrinogen, are deposited subendothelially

Q

Frequency of Down syndrome

A

1 in 1000 births worldwide

38
Q

Why are we doing antenatal screening

A
Down syndrome-trisomy 21
Edwards syndrome (trisomy 18) 
Patau syndrome (trisomy 13)
Neural tube defects(spinal cord defects)
39
Q

What will these screening tests tell the patient

vs diagnostic test

A

Screening tests: These do not give you a definitive answer, but let you know if your baby is at increased risk of Down syndrome. Screening tests do not harm the mother or baby.

Diagnostics test: These are very accurate, giving you a definitive answer. Diagnostic tests are usually offered to women whose babies are at increased risk, based on the result of the screening tests. A diagnostic test can increase your risk of having a miscarriage, so they aren’t routinely offered to all women.

40
Q

Second-trimester screening involves

A

The second trimester ‘quadruple test’ involves a different formula based on demographic information and the maternal serum levels of four markers; alpha-feto protein, human chorionic gonadotrophin, unconjugated estriol and inhibin

41
Q

Doctor, I know my screening test are high risk can I not have the diagnostic test

A

You don’t have to undergo any tests if you don’t want to. If you have a screening test that shows your baby is at increased risk of Down syndrome, you don’t have to proceed to the diagnostic test.
