Question | Answer |
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. |
