Abstract
please write abstract. Portal hypertension is a consequences generally of chronic and more rarely acute diseases affecting hepatic parenchyma or hepatic veins and as a disease it is usually concomitant with progressive impairment of liver functions. Portal hypertension IS primarily caused by the increase in resistance to portal outflow and secondly by an increase in splanchnic blood flow, which worsens and maintains the increased portal pressure. Increased portal inflow plays a role in the hyperdynamic circulation syndrome, a characteristic feature of portal hypertensive patients. Portal hypertension can lead to severe outcomes in patients with cirrhosis like bleeding of esophageal varices which have the greatest clinical impact. Duplex Doppler ultrasonography remains the first step In the evaluation of patients with chronic liver diseases and portal hyper-tension.
