ASSOCIATION OF DIFFERENT SONOGRAPHIC PARAMETERS WITH ONSET OF IUGR
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 12
Abstract
BACKGROUND Ultrasound has become the essential tool of modern obstetric practice as it is non-invasive, safe and radiation free. IUGR is defined as the pathologic inhibition of intrauterine foetal growth and the failure of the foetus to achieve its growth potential. Over the last decade, two different patterns of IUGR has been characterised on the basis of gestational age of onset. IUGR has a different phenotypic expression, evolution and outcome when it starts early in gestation called early-onset IUGR and it is different when it starts late in gestation known as late-onset IUGR. Early diagnosis and timely management decisions are the cornerstones for optimum outcome in these cases. MATERIALS AND METHODS This was a cross-sectional study collected from 152 pregnant women with IUGR foetuses, attending/ referred to Maharani Laxmi Bai Medical College and Hospital, Jhansi, Uttar Pradesh. The gray scale and colour Doppler sonography was routinely performed in all these IUGR pregnancies. Subsequently, the results were statistically analysed to find the association between different colour Doppler and gray scale parameters and time of onset of IUGR. RESULTS Abnormality in placenta, increased FL/AC ratio, increased S/D ratio and PI of umbilical artery, decreased S/D ratio and PI of middle cerebral artery and increased mean PI of uterine artery were more strongly associated with early-onset IUGR, while oligohydramnios was more strongly associated with late-onset IUGR. Low lying placenta, increased HC/AC ratio, decreased cerebroplacental ratio (CPR), increased S/D ratio of uterine artery, umbilical vein pulsation and increased PI of ductus venosus were equally associated with both early- and late-onset IUGR. CONCLUSION With the help of non-invasive, single study, sonographic gray scale and colour Doppler parameters, we can diagnose both types of IUGR, but most of the parameters were found to be more commonly associated with early-onset IUGR. So, we can use them to predict IUGR at an early stage and act accordingly for better perinatal outcome.
