Early Pregnancy Ultrasound For The Diagnosis Of Down’s syndrome
Down’s Syndrome
Can 4d Scan help in the diagnosis of Down’s Syndrome?
Down Syndrome is one common baby abnormality that can be screened through sonographic imaging.
Down Syndrome is a congenital abnormality seen in 1 of every 800 newborns.
The complications it brings about are not avoided though diagnosis may be established during pregnancy.
Its timely assessment is vital in preparing and laying out of medical intervention of the baby even prior to delivery.
Down Syndrome can be initially evaluated through screening tests.
This kind of test is not expensive but does not confirm the presence of DS.
Parents of the unborn baby need to make up their minds if a confirmatory diagnostic test is allowable to them.
Confirmation is necessary to know if the baby is prone to the common side effects of the abnormality.
Heart problems are just one of Down’s syndrome complications.
Another side effect would be irreversible pulmonary hypertension where there is a deterioration of pulmonary functions causing serious damage to the lungs.
There are several other symptoms of Downs.
These may be problems associated with eye and ear issues, as well as weight control issues, other pulmonary complications, susceptibility to any infection, and problems in the blood.
Diagnostic test are done to pregnant women 35 years old and above, whose family history suggests presence of genetic abnormalities in any kin, and who were screened and noted for a result suggestive of a baby with Down’s Syndrome.
Experiencing the diagnostic test is a choice and a risk for each mother to decide on and the American College of Obstetrics allows this.
The accuracy of the test at 99% is unquestionable.
Down’s Diagnostic Tests Can lead to Miscarriage
Limitation to the use of the diagnostic tests is on their capacity to cause miscarriage.
Even if most of the children with DS are prone to many complications, a few can still live an optimum existence.
There is a process at which the baby inside your tummy is evaluated for possibility of Down Syndrome. It is initially done through the screening tests for this condition.
Screening tests for DS include Nuchal Transluscency Test, Triple or Quadruple Screen, Integrated Screen, and Genetic Ultrasound.
The ideal time at which Nuchal Translucency scan should be performed is by 11 -13+6 weeks of pregnancy.
In Nuchal test, the skin fold with fluids at the back of the baby’s neck is assessed.
Triple Screen and Quadruple screen on the other hand measures existence of blood markers of DS in the pregnant mom.
Of the two screening tests, quadruple screen yield has higher reliability.
Genetic ultrasound is yet another test used to assess possible physical abnormalities in the baby.
The yield is more accurate if the modality is done by the 18th to 20th week of gestation.
Confirmatory tests for DS can be in the form of the following: Amniocentesis, Chorionic villus sampling, and Percutaneous Umbilical Blood Sampling.
Placental tissues that are utilized during the 8th to 12th week of pregnancy is through chorionic villus sampling.
The risk for miscarriage is relatively higher in Chorionic villus sampling.
Amniocentesis is done through utilization of the amniotic fluid.
The last test is done through the use of a blood sample from the umbilical cord.
This test should be scheduled by the 20th week of gestation.
Both Percutaneous Umbilical Blood Sampling and Amniocentesis shows lesser threat towards abortion.
4d baby scanning can improve the assessment process of the impact of Down’s syndrome on physical development of the fetus in the womb by showing such abnormalities such as club foot or heart problems.
