Abstract :

Introduction: Colour Doppler ultrasonography being non–invasive reliable and widely available tool, the present study intends to study the role of colour Doppler sonography in evaluation and diagnosis of portal hypertension. Methods: Forty portal hypertensive patients were studied using colour Doppler ultrasonogram from ASRAM Medical College, Eluru. Gray scale and colour Doppler along with duplex Doppler was used to study flow metric changes collaterals and other findings. Results: Majority of cases were in the age group 51–65 years with males being predominantly affected. Dilated portal vein was seen in 55% of cases. Hepatopetal, hepatofugal and bidirectional flow was seen in 60–85%, 7.5–10% and 2.5% of cases in different veins. 15–30% of veins showed thrombosis. Splenomegaly and ascites were seen in 87.5% and 77.5% respectively. Most frequent collaterals were gastrosplenic and splenorenal group. The most common cause of aetiology was cirrhosis. Conclusion: Colour Doppler ultrasonography detects various findings like dilated portal vein, respiratory variation, flow direction, splenomegaly and ascites accurately. It helps also helps in identifying the aetiology.
