Hi
Welcome to HCM,
Single
Umbilical artery in Doppler USG has few important implications on
pregnancy management.
1. You may go for repeat tertiary level USG, to confirm Single umbilical Artery, and to rule out any associated congenital malformation. Usually cardiac and other genitourinary abnormalities may be associated. Though isolated single umbilical artery can also happen. In few cases at birth, thses babies may have normal 2umbilical artery and one vein.
2. Babies with single umbilical artery have more chances of
IUGR. You need to get more frequent antenatal check ups, and serial USG. In case of IUGR, you may have to go for early delivery , once your baby is mature enough.
3. You must make sure that you deliver in an institution where Paediatric surgeons are available at the time of delivery.
4. In my opinion
Duphaston has no role in your case.
5. You also have an option to go for
Amniocentesis, to do the karyotyping of baby. There are chances of
Aneuploidy which is a chromosomal abnormaility. You may not want a very abnormal baby.
If in case you want to deliver a baby, at the time of birth also you should ask your Doctor to do karyotyping of your baby from
cord blood.
best of luck.
