Journal Title: Medpulse International Journal of Radiology - Year 2019, Vol 9, Issue 3
Abstract
Background and objectives: The aims and objectives of our study was to know the spectrum of colour Doppler and ultrasonographic finding in portal hypertension, and to look for various flow metric changes and finding out various porotosystemic collaterals in portal hypertensive patients. Methods: The present study is a study of colour Doppler and ultrasonographic findings in a clinically and ultrasonologically diagnosed portal hypertensive patient. 40 cases were studied using colour doppler coupled ultrasound machine. Initially using gray scale abdomen was scanned and findings noted. Later colour doppler was used along with duplex doppler to study flowmetric changes. Results: Dilated portal vein >13mm was seen in only 55% of cases, proving it to be less reliable criteria for diagnosis of portal hypertension if taken alone. Flow pattern wasseen.60-85%offlowwashepatofugalin various veins studied. Hepatofugal flow pattern was seen in7.5to10% indifferent veins. Bidirectional flow was least frequent and seen in 2.5%cases. Venous thrombosis in portal venous system noted. 15-30% of veins showed thrombosis. Splenomegaly and ascitis were frequent findings associated with portal hypertension. They were seen in 87.5% and 77.5% respectively. Various collaterals were detected sonographically. Most frequent were gastro splenic and splenorenal group. In our study most frequent etiology was cirrhos is. About 57.5% of cases were cirrhotics. Next frequent cause was portal vein occlusion seen in 12.5% cases. Males were more predominantly affected than females. And majority of cases were in the age group 51-65years. Interpretation and conclusion: Colourdopplerultrasonographyisaninitialinvestigationofchoiceinstudy of portal hypertension. It detects various findings like dilated portal vein, respiratory variation, flow directions plenomegaly ascites accurately. It helps in identifying cause of portal hypertension like cirrhosis, portal vein occlusion etc.
