A 55yo with hx of alcoholism, jaundice and cirrhosis is referred for a liver doppler
exam. Which of the following is an expected abnormal finding?
A. respiratory phasicity in portal vein flow
B. multiphase flow in the hepatic veins
C. dilated IVC
D. increased resistance in the hepatic artery - 🧠ANSWER ✔✔D. increased
resistance in the hepatic artery
Resistance in the hepatic artery will increase with the increase in resistance to flow
in the cirrhotic liver tissue. The coronary vein (a.k.a. left gastric vein) and the
umbilical vein will dilate with significant portal HTN. The IVC is not usually
affected by isolated cirrhosis. Hepatic vein flow will be multiphasic in the normal
patient. Normal portal venous flow will demonstrate mild respiratory phasicity.
