What is a Splanchnic Plexus Block?

A splanchnic plexus block is a minimally invasive procedure used to manage chronic abdominal pain. The splanchnic nerves, which originate from the thoracic spinal cord, transmit pain signals from the abdominal organs to the brain. By injecting medication around these nerves, the procedure can effectively block pain signals and provide significant relief.

Indications for Splanchnic Plexus Block

Chronic Pancreatitis

Persistent inflammation of the pancreas causing severe abdominal pain.

Abdominal Cancer Pain

Pain associated with cancers of the abdominal organs, such as pancreatic, stomach, or liver cancer.

Refractory Abdominal Pain

Severe abdominal pain that does not respond to conventional treatments.

Chronic Mesenteric Ischemia

Pain resulting from insufficient blood flow to the intestines.

Procedure

Frame 4

Preparation

The patient is positioned comfortably, often lying on their stomach, and the skin over the target area is cleaned and numbed with a local anesthetic.
Frame 4

Imaging Guidance

Using fluoroscopy (X-ray guidance) or CT scan, the physician accurately guides a needle to the area near the splanchnic nerves.
Frame 4

Injection

A mixture of a local anesthetic and sometimes a corticosteroid or neurolytic agent is injected to block the nerve signals.
Frame 4

Observation

The patient is monitored for a short time after the injection to assess immediate pain relief and any adverse reactions.
