Q

Where does the portal vein arise from?

A

It rises from the vitelline network and punctures through the fibrous Glisson’s capsule of the liver and is sheathed with the fibrous lining.

Q

What does the Inferior Mesenteric Vein do?

A

It courses inferior to superior and drains the large intestine and empties blood into the splenic vein. It can drain directly into the SMV or the Splenic Confluence

Q

What structure is used as a landmark for the pancreas and why?

A

The Portal System, specifically the splenic vein because it is directly posterior to the pancreas.

17
Q

What is the physiology of the Portal System?

A

It brings nutrient-rich blood from the abdominal organs and bowel to the liver for metabolism and detoxification.

18
Q

Which vessels are included in the Portal Triad?

A

The Portal Vein, Hepatic Artery, and Common BIle Duct

19
Q

The Main Portal Vein courses superiorly. How long is the MPV?

A

5-6 cm

20
Q

Which vessels enter and which leave the liver through Porta Hepatis.

A

The Portal Vein and Hepatic Artery enter the liver. the Common Bile Duct leaves the liver carrying blood to the digestive tract.

21
Q

Describe the Left Branch of Portal Vein

A

It courses horizontally, branches into the lateral and medial divisions, and feeds the left and caudate lobe of liver.

22
Q

What is different about the sizes of the Left and Right Portal Vein?

A

The Left PV is Longer and Narrower

23
Q

Describe the Right Branch of the Portal Vein

A

It courses to the right and feeds the right lobe of the liver. It branches into the anterior and posterior sections.

24
Q

The normal diameter of the portal vein should not exceed…?

A

1.3 cm or 13 mm

25
Q

What is the function of the hepatic veins? Do they connect to the Portal System

A

They drain blood from the liver to the IVC. They do NOT connect to the Portal System

26
Q

In embryology, the portal vein is fully developed by which week of pregnancy?

A

The 8th week

27
Q

Coursing superiorly, how long is the main portal vein?

A

5-6 cm

28
Q

What vessels create the “Mickey Mouse” Sign on a transverse image?

A

Portal Vein, Hepatic Artery, CBD

29
Q

Do any of the vessels the portal triad split off at any point? Why?

A

No, they’re encased in a fiberous sheath that holds the vessels together

30
Q

What do the hepatic veins do?

A

Drain blood from the liver and empty into the IVC

31
Q

What does the Hepatic Artery do

A

brings oxygenated blood into the liver

32
Q

What does the portal vein do?

A

Supplies nutrient-rich blood to the liver for metabolism and detoxification

33
Q

What does the bile duct do?

A

Carries bile from the liver to the digestive tract.

34
Q

Which vein (portal or hepatic) appears with hyperechoic walls because of their high collagen content and sheath covering?

A

Portal Veins

35
Q

Describe Hepatopetal blood flow

A

blood that flows toward the liver

36
Q

Describe Hepatofugal blood flow

A

blood that flows away from the liver

37
Q

The bifurcation of the Right Portal Vein is best seen in which scan plane?

A

Sagittal
