PV location in relation to the pancreas

PV is shown posterior to the head of the pancreas

SMA in relation to the pancreas

SMA is sandwiched between the aorta and splenic vein

left renal vein location in relation to the pancreas

LRV is anterior to the aorta and posterior to the SMA

superior border of the pancreas

the celiac axis

Posterior border of the pancreas

The portal venous system

The head of the pancreas lies

“in the lap” of the C-loop of the duodenum

The SMV in relation to the ucinate process and neck and body of the pancreas

The SMV crosses anterior to the ucinate process and posterior to the neck and body of the pancreas

The uncinate process

The small, curved tip at the end of the head of the pancreas

Most inferior portion of the pancreas

The head

Tongue-like extension of the pancreatic neck

The uncinate process

The portal vein is formed

posterior to the neck by the junction of the SMV and splenic veins

The pancreatic head and body is often included as

part of the body

The largest portion of the pancreas

the body

The portal splenic confluence lies posterior to

The neck of the pancreas

The splenic artery and vein form the

Posterior and superior border of the tail

The posterior wall of the stomach in relation to the tail of the pancreas

The stomach overlies the anterior borded of the tail of the pancreas

To better visualize the pancreas (specifically the pancreatic tail)

Lay the patient LLD, supine, or RLD

drink water to fill the stomach

Main pancreatic ducts

Duct of wirsung (connects directly to 2nd portion of duodenum

Duct of santorini (secondary duct that drains the upper anterior head)
