To Identify the Predictive Role of Aortic Isthmus Blood Flow in IUGR
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2018, Vol 6, Issue 7
Abstract
The purpose of this study was to study To Identify the Predictive Role of Aortic Isthmus Blood Flow in IUGR, which is conducted in the Dept. of Radio Diagnosis. AI blood flow represents the output flow of both ventricles and the difference of placental and cerebral blood flow resistance. The AI is the only Arterial connection between the right ventricle, which mainly supplies the systemic and placental circulation, and the left ventricle, essentially corresponding to the cerebral vascular network. Consequently, its blood flow pattern reflects the balance between both ventricular outputs and the differences in the impedance of both vascular systems. This study confirms and expands on previous observations suggesting that the occurrence of retrograde blood flow in the AoI is associated with adverse perinatal outcome. Growth-restricted preterm foetuses showed decreased absolute velocities in the AoI, very likely reflecting reduced systemic blood flow. Combination of AoI and umbilical artery Doppler is the best indicator for prediction of IUGR. Aortic Isthmus changes occur 24-48 hrs before deterioration of flow in Ductus Venosus.
