Which of the following positions best describes the location of the celiac plexus?
Which of the following positions best describes the location of the celiac plexus?
Show Hint
It wraps the celiac trunk, which springs off the front of the aorta.
Updated On: Jun 24, 2026
- Anterolateral to the aorta
- Posterolateral to the aorta
- Anterolateral to the sympathetic chain
- Anteromedial to the sympathetic chain
Show Solution
The Correct Option is A
Solution and Explanation
Picture the upper abdomen at the L1 level. The aorta runs straight down the midline, hugging the front of the spine. The celiac plexus is the dense net of autonomic fibres wrapped around the celiac trunk as it leaves the aorta.
Since the celiac trunk springs forward off the front of the aorta, the plexus that surrounds it naturally sits in front of and on either side of the aorta. That is the meaning of anterolateral to the aorta. It cannot be behind the vessel, so a posterolateral position is wrong.
The sympathetic chains are a separate landmark, running down the sides of the vertebral bodies, lateral to the plexus. Describing the celiac plexus by the sympathetic chain misplaces it, because the plexus actually lies anterior and medial to those chains, not as options C and D phrase it.
This periaortic, anterolateral seat is also why a celiac plexus block is aimed there to relieve pain from pancreatic and other upper abdominal cancers.
So the best description is anterolateral to the aorta.
\[\boxed{\text{Anterolateral to the aorta}}\]
