Sympathetic Block

A Sympathetic Block consists of an injection of a local anesthetic into or around the sympathetic nerves.


Sympathetic Block

A lumbar sympathetic block is a procedure that reduces pain and swelling in the lower extremities and increases circulation and mobility. These effects are achieved through an injection of local anesthetic into or around the sympathetic nerves. The sympathetic nerves are are located on the either side of spine in the lower back and are part of the sympathetic nervous system.

During this minimally invasive AccuCision® Spine procedure, local anesthetic is applied to the patient before the doctor inserts a needle into the area of the sympathetic nerves. Once the needle is in place, an injection of anesthetic medication will be supplied to the sympathetic nerves. After the injection, the needle is removed and the injection site is covered with a band-aid.

An increase in the temperature in a patient’s feet and legs indicates the injection was successful. Patients typically notice their lower legs becomes rosy in color, and experience a marked decrease in lower extremity pain.
