RESULTS
Optimal aortic isthmus waveform assessment could be obtained in all
cases .Out of 45 cases recruited 2 cases lost to follow up and 5 cases
got delivered at other hospital, in these cases aortic isthmus doppler
analysis at least 48-72 hours prior to delivery was not available, hence
these cases were excluded from the study. Of the total analyzed 38
cases, 25 had antegrade diastolic flow in the aortic isthmus and 13 had
retrograde diastolic flow in the aortic isthmus.
