URR Flashcards
(45 cards)
What is the purpose of the Liver ultrasound imaging reporting & data system?
It is used for ultrasound screening in patients at risk for developing HCC (hepatocellular carcinoma).
What is a potential pathway for varices in patients with cirrhosis?
Blood moves from the coronary and short gastric veins into the esophageal veins.
What does elastography measure?
It measures stiffness.
What effect can estrogen replacement therapy & pregnancy have on hemangiomas?
It can cause hemangiomas to increase in size.
What is indicated by a tubular vessel connecting to the left portal vein in a patient with chronic cirrhosis?
A dilated, patent umbilical vein.
What is a sign of significant portal hypertension?
It indicates low velocity flow moving in a caudal direction.
What can cause fulminant hepatitis?
Acetaminophen overdose, as well as Hepatitis A, B, and C, leading to acute liver failure and requiring liver transplant.
How is liver transplant rejection described in Doppler appearance?
It is described as high resistance flow in the Hepatic Artery
What are liver adenomas?
They are highly vascular benign liver tumors with an increase risk of hemorrhage and malignant transformation.
What is the usual recommendation for liver adenomas?
Surgical resection is usually recommended.
Recanalization of the ligamentum teres is a sign often associated with
Cirrhosis
What is a dilated umbilical vein a sign of?
Portal hypertension
A dilated umbilical vein indicates increased pressure in the portal venous system.
What are biliary hamartomas also known as?
Meyenburg complexes
These are focal developmental lesions of the liver composed of groups of dilated intrahepatic ducts within the dense stroma.
What liver condition is associated with biliary hamartomas?
Cholangiocarcinoma, congenital hepatic fibrosis, ADPD
What can hepatitis spread to and cause?
Cholecystitis
Hepatitis can lead to inflammation of the gallbladder, known as cholecystitis, causing wall thickening and GB sludge.
What are hepatomas?
Solitary, solid masses of varied echogenicity
Hepatomas can grow to a very large size and vary in their ultrasound appearance.
What can cause narrowing of hepatic veins?
Cirrhotic changes
Narrowing of hepatic veins leads to decreased outflow and loss of pulsatility.
What is a sign of narrowed hepatic veins?
Cirrhosis
##
The contour changes can indicate underlying liver pathology.
What effect do oral contraceptives have on the liver?
They can cause Budd-Chiari syndrome
Use of oral contraceptives is associated with thickening of blood and potential hepatic vascular conditions.
Fill in the blank: A dilated umbilical vein is a sign of _______.
Portal hypertension
True or False: Hepatomas are typically multiple lesions in the liver.
False
Hepatomas are usually solitary masses.
What is the structure of the portal vein system?
The portal vein system collects blood from multiple organs that are potential sources for primary carcinoma.
What is steatosis?
Steatosis is the accumulation of triglycerides in the liver.
What is Hemochromatosis?
Hemochromatosis is characterized by iron accumulation in the liver.
