The celiac plexus or coeliac plexus, also known as the solar plexus because of its radiating nerve fibers,[1] is a complex network of nerves (a nerve plexus) located in the abdomen, where the celiac trunk, superior mesenteric artery, and renal arteries branch from the abdominal aorta is located. It is behind the stomach and the omental bursa, and in front of the crura of the diaphragm, on the level of the first lumbar vertebra.
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.
The celiac plexus proper consists of the celiac ganglia with a network of interconnecting fibers. The aorticorenal ganglia are often considered to be part of the celiac ganglia, and thus, part of the plexus.

Approximate location of the celiac plexus on the coronal plane
The celiac plexus includes a number of smaller plexuses:
- Hepatic plexus
- Splenic plexus
- Gastric plexus
- Pancreatic plexus
- Suprarenal plexus
Other plexuses that are derived from the celiac plexus:
- Renal plexus
- Testicular plexus / ovarian plexus
- Superior mesenteric plexus
- Inferior mesenteric plexus
Clinical significance
Lower half of right sympathetic cord
The celiac plexus is often popularly referred to as the solar plexus, generally in the context of a blow to the stomach. In many of these cases, it is not the celiac plexus itself being referred to, but rather the region where it is located. A blow to the stomach can upset this region. This can cause the diaphragm to spasm, resulting in difficulty in breathing—a sensation commonly known as "getting the wind knocked out of you". A blow to this region can also affect the celiac plexus itself, possibly interfering with the functioning of the viscera, as well as causing great pain.
A celiac plexus block by means of fluoroscopically guided injection is sometimes used to treat intractable pain from cancers[2] such as pancreatic cancer. Frequently, celiac plexus block is performed by pain management specialists and radiologists, with CT scans for guidance. Intractable pain related to chronic pancreatitis is an important indication for celiac plexus ablation.
