no outside lining to help us see it
Where is the pancreas found intra or retroperitoneum?
What are the landmarks around the pancreas?
anterior pararenal space
posterior to the lesser sac
What is the technical challenge of US pancreas?
ileus-dilate loops of bowel without peristalsis (blockage of bowel)
What organ is the anterior boundry of the panc?
posterior: Ao and IVC
What lies in the anterior pararenal space?
What is the typical measurement of the panc?
12cm x 2cm
What are the four sections of the panc?
head, neck, body, and tail
What kind of position does the panc lie?
from the concavity of the duodenum to the hilum of the spleen
Where does the head of the panc lie?
anterior to the ivc and left renal vein
inferior to the caudate lobe and portal vein
finish slide 9
What artery is above the panc?
the celiac trunk (superior)
find seagull sign and angle down to see panc
What structure does the superior mesenteric vein cross?
crosses anterior to the uncinate process of the head of the gland and posterior to the neck and body of the pancreas
What is the uncinate process?
the small, curved tip at the end of the head of the pancres
lies anterior to the inferior vena cava and posterior to the superior mesenteric vein
What passes through a groove posterior to the pancreatic head and the gastroduodenal artery?
the common bile duct
What vessel lives in the pancreatic notch?
notch - space between head and uncinate process
What is found directly anterior to the portal-splenic confluence or SMV?
the neck of the panc
What is formed posterior to the neck by the junction of the SMV and SV?
The portal vein
What part of the panc is the largest part?
lies posterior to the stomach and anterior to the origin of the portal vein
What part of the panc rests anteriorly to the Ao , the origin of the SMA the Left renal vessels, left adrenal glands and left kidney?
The body of the pancreas
What is the superior border of the panc body?
What courses the posteromedial surface of the pancreas to join the main portal vein?
the splenic vein
Where does the tail of the pancreas lie?
anterior to the left kidney, close to the spleen and left colic flexure
The splenic vein forms the _________ border, and the _______ forms the superoanterior border.
What is Wirsung's duct?
the primary duct of the panc extending the ENTIRE length of the gland
receives tributaires from lobules at the right angles and enters the medial second part of the duodenum with the cbd at Vater's ampulla
What is Santorini's duct?
a secondary duct that drains the upper anterior head
it enters the duodenum at the minor papilla approx 2cm (smaller duct) at ampulla of vater.
What are the measurements for the panc?
Head < 2.5cm
tail < 2.0 cm
What is the echogenicity of the pancreas?
> spleen (depends on fatty/fibrous texture)
What is the echotexture of the pancreas?
What is the surface of the pancreas look like...
smooth to slightly lobular (islets of langerhans)
