Doppler tomography (US) has enabled the noninvasive Investigation of viscus and portal hemodynamics. Thus, several Investigators have tried to assess malignant hypertension with Doppler United States of America in patients with liver disease. especially, any Doppler technique that might be an acceptable substitute for the invasive assessment of malignant hypertension, like mensuration of the viscus blood pressure Gradient (hvpg), would be extremely fascinating. However, at present, each the clinical quality and also the price of Doppler United States of America within the assessment of malignant hypertension stay unsettled. Doppler indices that are usually used for analysis of malignant hypertension embrace the mensuration of portal and splenetic blood flow rate and resistive index of splenetic, hepatic, and superior peritoneum arteries. However, these indices square measure suffering from an absence of reliability and accuracy thanks to intra- and interobserver variability and interequipment variability. The Doppler undulation of the vena in healthy subjects is often triphasic (two negative waves and one positive wave) owing to central blood pressure variations thanks to the oscillation. It's Been established that the traditional triphasic vena undulation is remodeled into a biphasic or monophasic undulation in patients with liver disease. Moreover, a monophasic undulation has been shown to Correlate with a high child-pugh score and a poor survival rate. Thus, it'd be affordable to theorise that abnormalities within the vena undulation square measure associated with the degree of malignant hypertension. To our information, one study has been performed to look at a attainable correlation between abnormalities within the vena undulation and also the severity of malignant hypertension in patients with liver disease.
