The sympathetic is a method for temporary or long-term elimination of sympathetic innervation . It will u. a. used to improve blood circulation in the legs or arms.

The sympathetic nervous system causes the blood vessels to constrict in the equilibrium of the vegetative systems, which is why in many cases vasodilation can be achieved after it has been deactivated . Closed vessels are not reopened, but the collaterals are better supplied with blood.

Conduction anesthesia of the stellate ganglion can be used to improve blood flow to the upper extremities . This blockage leads to vasodilation in the entire catchment area, reduced sweat secretion ( anhidrosis ) and Horner's syndrome . The latter is a sign of the successful implementation of the blockade. The temporary stellate blockade is z. B. for the therapy of an advanced complex regional pain syndrome carried out. Surgical removal of the stellate ganglion is the last resort of choice for Raynaud's disease .

The sympathetic nerve plexus can also be blocked in other parts of the body. The sympathetic plexus located on the large abdominal vessels can z. B. can be switched off in local anesthesia under control in the computed tomogram by injection of concentrated alcohol (method of interventional radiology ).
