Can do prenatal diagnosis at 12 weeks gestation.
Gone are the days when that was reserved for the day of the birth all the information about the baby.
Increasingly, the technology is on our side and no mother exemption when the future is at stake.
With Purification Tavares, Professor of medical genetics, get to know one of the options for the tests that can be done in prenatal diagnosis: the harvest done villus (CVC).
“It’s the set of procedures that allows information about a developing fetus, which apply in cases of antenatal screening with increased risk, when you sense ultrasound abnormalities, or when there is already an anomaly in family and wishes to know if the baby has the disease concerned ‘, refers to Purification Tavares, Director of the CGC-Genetic centre clinic.
These techniques are used to search for «chromosomal anomalies and genetic diseases with possibility of molecular diagnostic», describes retro style maternity slippers on Vintagewill.com.
Villus sampling done
The harvest of villi done is one of the possibilities for prenatal diagnosis, which allows the detection of problems in the fetus or the confirmation that this develops properly. «The fetal material for analysis is obtained through placental villi biopsy», informs Purification Tavares, according to which ‘ the villi done are usually obtained by transabdominal, with the help of ultrasound, from the twelfth week of gestation ‘.
According to Purification Tavares, the main advantage of this exam in relation to amniocentesis (usually performed after the 15th week) is to be held sooner, at 12 weeks, shortly after the sonogram, allowing ‘ inform prospective parents with greater advance at 13 weeks, reducing anxiety or allowing for timely decision making». In addition, ‘ the sensitivity rate CVS is identical», says.
Analysis of risk
«In the case of an invasive technique, there is always a risk associated with it. The risk is directly dependent on the experience of the doctor ‘ explains Purification Tavares.
Compared with amniocentesis, “currently the risk associated with each of the techniques is next, slightly higher for the harvest of villi done.
Accounted for in the literature there is between 0.5 to 1% of risk of fetal complications. In our country, experienced doctors, the risk of amniocentesis may be less than 0,3%, which is considered very low. Other doctors state that the risk of CVS is also reduced», continues to specialist.
Evaluation of results
If the test reveals a genetic anomaly, ‘ we must interpret the anomaly found, since this can
result in a slight, pathology can be irrelevant, or constitute a serious anomaly. All these situations have to be carefully evaluated by the geneticist explained to the couple and should be considered the following options for each case», says Tavares Purification.
Prenatal diagnosis by villi coriais is performed, usually in hospitals and clinics, and the product submitted to the CGC-Genetic Centre Clinic (our site), where studies are performed for genetic diagnosis, as well as genetic queries.
