Prinos dopplerovskeho vysetreni pri prenatalni diagnostice vybranych typu vrozenych vyvojovych vad.

Abstract

Coloured and pulsed Doppler has increasingly been becoming routine investigation in specialized prenatal screening. By pulsed Doppler we can observe through-flow conditions in vessels which respond to resistance changes in peripheral tissues. The measurement in umbilical artery provides worth information about functional state of placenta. Consecutive changes in foetal circulation reflect foetal reaction on progressive distress and enable estimation of his/her reserves. The aims of this study were: to verify possibilities of Doppler system utilization, as an auxiliary method, in detection of congenital malformation during prenatal diagnosis and in assessment of their relevance; to find out whether umbilical artery pulsatility (PI) and middle cerebral artery PI measurement may be used in specific detection of chromosomal aberrations (trisomies), as an additional parameter.Available from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi
