Role of colour doppler sonography in evaluation of portal venous hypertension
Journal Title: Medpulse International Journal of Radiology - Year 2018, Vol 7, Issue 1
Abstract
Background: Portal hypertension (PH) is the result of increased hepatic vascular resistance and portal blood flow. In majority of cases portal hypertension is seen as a major complication of cirrhosis although less commonly seen in variety of extrahepaticdiseases. PH leads to serious complications, such as variceal bleeding, portal hypertensive enteropathy, ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, and hepatic encephalopathy.PH is responsible for significant morbidity and mortality in patients with decompensated cirrhosis. Objectives: 1. To diagnose and establish the cause of Portal hypertension, 2. To evaluate the spectrum of Colour Doppler sonographic findings in Portal hypertension, 3.To study flowmetric changes in Portal hypertension, 4. To look for the presence of various Portosystemic collaterals. Methodology: A Cross sectional study was conducted with the sample size of 40. All patients referred to the Department of Radiodiagnosis with the clinically suspected cases of portal hypertension, in a period of 2 years from January 2014 to October 2015 were subjected for the study. Results: Dilated Portal vein > 13mm and Respiratory variations of PV diameter < 20% can be used as sensitive signs of Portal Hypertension. Direction of flow in PV,SMV and splenic vein and Various Portsystemic collaterals can be evaluated using Colour Doppler Ultrasound. Ultrasound is sensitive in detecting the associated findings of PH like Ascites and Splenomegaly. Conclusion: Colour Doppler ultrasound is a non-invasive, relatively cheap and easily accessible imaging modality that helps in making the diagnosis of clinically significant portal hypertension. It also provides useful information as to it’s cause and presence of complications.It was found to provide important information on the hemodynamic alterations in porto-hepatic venous system in patients with Portal Hypertension.
