DVT423-SW4

USIDMS Hepatic Doppler

QuestionAnswer
What two vessels constitute hepatic inflow? The Hepatic Artery and Portal Vein.
True or False: Sudden onset of ascites, acute abdominal pain, and elevated D-dimer are all indications for a Hepatic Doppler study. True.
True or False: The hepatic veins are intersegmental and contain valves. False. They do not have valves.
What two things affect portal vein diameter and velocity of flow? Patient respiration and ingestion of food.
When is portal vein diameter increased? Portal Hypertension, Congestive Heart Failure, Constrictive pericarditis, and Portal Vein Thrombosis.
What do the Doppler Spectral Waveforms of the portal vein look like? Monophasic and slightly pulsatile or undulating.
What does the Hepatic Vein waveforms look like? Pulsatile triphasic waveform with antegrade and retrograde flow. It changes with the cyclic pressure changes within the heart.
What does the Valsalva maneuver do to the Hepatic Vein waveform? Diminishes the waveform pulsatility.
True or False: The Portal Vein and the Hepatic Artery carry blood flowing in the same direction. True. It is Hepatopetal Flow- toward the liver.
What is the "hepatic buffer response"? When the portal blood flow increases, hepatic arterial flow decreases and vice versa.
