Hepatic artery waveform ultrasound
WebIn these conditions Doppler ultrasound can provide important information on the hemodynamics of the portal venous system, the hepatic artery and the hepatic veins. Methods: The value of Doppler ultrasound in the assessment of the patient with cirrhosis and portal hypertension was determined by reviewing the literature. WebA normal hepatic artery spectral Doppler waveform on serial ultrasound examinations accurately excludes significant hepatic artery disease. • Hepatic artery occlusion and stenosis over a long period may have a less devastating consequence on liver graft function; hepatic abscess formation is more common. •
