What is fetal cardiac hyperechoic bowel?
What does a presence of a small hyperechoic focus in the left ventricle means? (Found during an ultra sound test)
Are there any future implications on the childs health, does it increase the probability for Down syndrome?
Is fetal hyperechoic bowel on second-trimester sonogram an indication for amniocentesis?
Studies performed to date suggest that this isolated finding in a low risk patient, a patient who has negative family history of chromosome abnormality, is not associated with increased likelihood of Down syndrome. The risk may be higher, however, when other sonographic abnormalities or risk factors are present. If the woman is < 35 years at delivery and the multile marker test for spina bifida and chromosome abnormality (the blood test at 16-18 weeks) is negative, and no other fetal anomalies were noted, the risk for a real problem is low.
Hyperechoic bowel on second trimester study mandates work up for chromosome study, cystic fibrosis, and abnormalities of the fetal bowel. Nevertheless, the majority of these cases will result in a normal outcome.
If the fetus is showing evidence for both ultrasonic abnormalities amniocentesis is indicated.
