F100Dopplerometry at the prenatal diagnosis of congenital defects

Abstract

BackgroundPulse and colour Dopplerometry is going to be more and more routine investigation in the frame of specialised prenatal investigation. Despite the huge number of the works in this field in the past years we have found only very limited information about utilisation of these both methods at the cases of congenital defects found in utero, especially in the first trimester of pregnancy.MethodDuring the past two years we have investigated both by pulse and colour Doppler mostly cord vessels, art. cerebri media, art. renalis and truncus arteriosus. By the colour Doppler we evaluated heart, moving of the chest and we assessed placental blood circulation in lacunas.ResultsOur collection consists from 28 pregnant women, where we have found congenital defects. There were chromosomal aberrations, morphological defects, serious intrauterine hypoplasias and Rh incompatibility there. Evaluation was not possible by the absolute values and so we divided the curves into four groups: higher, normal and lower levels, and zero flow. The results are not specific for individual defects, as we expected, but it is an option to utilise them at a suspicion for abnormal intrauterine findings.ConclusionDopplerometry at the congenital defects has its limited value but it is helpful at the complex evaluation of the foetus health condition.
