The celiac plexus, also known as the solar plexus because of its radiating nerve fibers,[1] is a complex network of nerves located in the abdomen, near where the celiac trunk, superior mesenteric artery, and renal arteries branch from the abdominal aorta.

The plexus is formed in part by the greater and lesser splanchnic nerves of both sides, and fibers from the anterior and posterior vagal trunks.

[citation needed] A blow to this region may cause the diaphragm to spasm, resulting in difficulty in breathing—a sensation commonly known as "getting the wind knocked out of you".

Such a block may be performed by pain management specialists and radiologists, with CT scans for guidance.

Intractable pain related to chronic pancreatitis may be an indication for celiac plexus ablation.
