A
  1. Pancreaticoduodenal artery

2. Branches of the splenic artery

2
Q

What does the pancreaticoduodenal artery supply? (2)

A
  1. The head of the pancreas

2. Part of the duodenum

3
Q

What do the branches of the splenic artery supply? (2)

A
  1. Body

2. Tail

4
Q

Where do the branches of the splenic artery course?

A

On the superior edge tortuous

- before it enters the spleen

5
Q

What are the vein tributaries of the pancreas? (2)

A
  1. SMV

2. SPL V

6
Q

Is the pancreas intra or retroperitoneal?

A

Retroperitoneum

7
Q

A
  1. Head
  2. Neck
  3. Body
  4. Tail
8
Q

What is considered part of the head?

A

The uncinate process

9
Q

Where is the head of the pancreas located?

A

More inferior to the body and the tail

10
Q

Where is the neck and body located?

A

More superficial than the head to the tail

11
Q

Where is the tail located?

A

More superior direction towards the spleen

12
Q

What is the echogenicity of the pancreas? (compared to the liver)

A

Usually isoechonic or hyperechonic

13
Q

What happens to the echogenicity of the pancreas as you get older?

A

It increases

14
Q

What is the echogenicity of the uncinate process?

A

Hypoechonic to the rest of the pancreas

15
Q

What is the echotexture of the pancreas?

A

Homogenous

- can have molten appearance

16
Q

Does the pancreas vary in size between different sexes?

A

No

17
Q

What is the size of the head?

A

Largest in dimension

18
Q

What is the size of the neck?

A

Smallest in dimension

19
Q

What is the size of the body/tail?

A

Slightly smaller than the head

20
Q

What is the contour of the pancreas?

A

Usually smooth

- occasionally lobulated

21
Q

A
  1. Gastroduodenal artery
  2. Common bile duct
  3. Inferior vena cava
22
Q

How does the GDA help us locate the head?

A

It is anterior lateral aspect of the head

23
Q

How does the CBD help us locate the head?

A

It is posterior lateral aspect of the head

24
Q

How does the IVC help up locate the head?

A

It is posterior to it

25
Q

What is a landmark for the neck and uncinate process? (2)

A
  1. Superior mesenteric vein

2. Splenic confluence

26
Q

How does the SMV help up locate the neck and uncinate process?

A

It is anterior to it

27
Q

How does the splenic confluence help us locate the neck and uncinate process?

A

It is posterior to it

28
Q

What are the landmarks for the body of the pancreas? (3)

A
  1. Superior mesenteric artery
  2. Portosplenic vein
  3. Superior mesenteric vein
29
Q

What is the easiest landmark for the body?

A

SMA

- directly above it

30
Q

How does the portosplenic vein help up locate the body?

A

It is medial anterior to it

31
Q

What landmark helps us locate the tail of the pancreas?

A

The splenic vein

32
Q

How does the splenic vein help us located the tail?

A

It is posterior to it

- splenic artery is tortuous and travels adjacent to the splenic vein (seen in cross section)
