Transpyloric plane

From Wikipedia, the free encyclopedia

Transpyloric plane
Surface lines of the front of the thorax and abdomen. (Transpyloric is top horizontal line.)
Front of abdomen, showing surface markings for duodenum, pancreas, and kidneys.
Latin	planum transpyloricum
Gray's	subject #286 1315

An upper transverse line, the transpyloric is located halfway between the jugular notch and the upper border of the symphysis pubis; this indicates the margin of the transpyloric plane, which in most cases cuts through the pylorus, the tips of the ninth costal cartilages and the lower border of the first lumbar vertebra.

[edit] Structures crossed

The transpyloric plane is clinically notable because it passes through several important abdominal structures. These include: Other structures in this plane include:

• the fundus of the gallbladder
• the neck of the pancreas
• the pancreatic body^[1]
• the origins of the superior mesenteric artery^[1] and portal vein^[1]
• the left and right colic flexure ^[1]
• the left hilum of the kidney ^[1]
• the right upper pole of the kidney ^[1]
• the root of the transverse mesocolon
• duodenojejunal flexure ^[1]
• the 2nd part of the duodenum
• the upper part of conus medullaris^[2]
• the spleen
