Brief Answer:
NO NEED TO REPEAT SCAN, REASONS DISCUSSED

Detailed Answer:
Hello
Thanks for trusting us with your health concern.
I empathize with your situation, and am sorry about the scan results.
To answer your questions -
In my opinion, the scan is pretty much conclusive, and all the findings are very clearly elucidated.
THere is no point in having a repeat scan done, unless you very much wish for a second opinion.
Regarding why it happened.
IT is a very complex situation.
Basically, the baby is having MCA - multiple congenital anomalies.
Some abnormalities occur in 4 % of the population, but multiple major anomalies like the ones found in this baby occur in around 1 % of the population, they are quite rare.
A few reasons are postulated.
The main thing to remember, is that , in more than 50 % of cases, there is no obvious cause - the medical term is idiopathic.
Recurrence rate is around 5 %, so dont be disheartened, you have more than 90 % chance of having a normal pregnancy again.
Now for the possible causes.
The most obvious cause is abnormality of chromosomes, during the meeting of the egg and sperm, chromosomal disturbances arise, leading to defects in organ systems.
This is a random event and can happen to anyone, it is just random.
There are certain factors that influence it, and I would discuss them, so that you can take due precautions next time.
The first is maternal age.
After 30, the risk of abnormalities increases, there is nothing you can do about your age.
The second is deficiency of folic acid, but you have taken adequate folic acid this time.
Next time around, you should take 5 mg per day daily (instead of 0.4 mg ) for 3 months prior to conception and continue the dosage throughout pregnancy.
Diabetes again is a leading cause, please get your OGTT done and HBA1C ( oral glucose tolerance test and glycosylated hemoglobin ).
Get your and husbands blood groups tested for any abnormality.
Get yourself vaccinated against Rubella infection before planning the next pregnancy.
Avoid any kind of drugs, smoking, alcohol and exposure to toxins, fumes, chemicals , radiation during pregnancy.
High grade fever is best prevented.
I can understand the turmoil you are going through right now, but please be reassured in the fact that most women with one anomalous baby go on to have normal babies the next time around.
Once you go for termination of this pregnancy, please ensure that your baby ( foetus ) is sent for chromosomal evaluation and a formal pathological evaluation to arrive at any syndrome that might be present.
This would prepare you for the next time.
Just a word - is this a consanguinous marriage ( are you and your husband related ) ? - That would increase chances of malformations.
HOpe the answer helped you to some extent.
All the best
Please feel free to discuss further

Brief Answer:
YOUR DOCTOR WOULD KNOW

Detailed Answer:
Hi .
If there is no blood relation, there is nothing to worry.
You should request the doctor to send the fetus for autopsy and chromosomal evaluation.
There would be various centres specializing in Genetic and Fetal Medicine, that would be best equipped for such an evaluation.
I do not belong to XXXXXXX hence am unable to provide specific names, a reasonably good Specialist would know for sure.
Am sure your doctor would do the needful.
Just ensure it is done, actually the suggestion should have come from her .
Take care.
