Coeliac Plexus Block
Posted on: June 14, 2015

The coeliac plexus is the largest plexus of the sympathetic nervous system. It contains preganglionic sympathetic fibers from greater and lesser splanchnic nerves (emerge from the thoracic sympathetic ganglia, T5 to T12) as well as postganglionic sympathetic and preganglionic parasympathetic fibers. It provides sensory innervation and sympathetic outflow to stomach, liver, spleen, pancreas, kidney and GI tract up to splenic flexure. Plexus is located at the level of T12-L2 (usually L1) and lies anterior to aorta in the retroperitoneal space.
