The amount of compensatory sweating depends on the patient, the damage that the white rami communicans incurs, and the amount of cell body reorganization in the spinal cord after surgery.Other potential complications include inadequate resection of the ganglia, gustatory sweating, pneumothorax, cardiac dysfunction, post-operative pain, and finally Horner’s syndrome secondary to resection of the stellate ganglion.www.ubcmj.com/pdf/ubcmj_2_1_2010_24-29.pdf

RA, lupus and other connective tissue disorders may have abnormalities of sympathetic postganglionic function
Rheumatoid arthritis, systemic lupus erythematosus, and other connective tissue disorders may have abnormalities of sympathetic postganglionic function. Some of these patients may have autoantibodies to ganglionic acetylcholine receptors. Autoimmune thyroiditis, as with chronic thyroiditis and Hashimoto thyroiditis, can be associated with some features of Sjögren syndrome such as xerostomia. Patients with systemic sclerosis and mixed connective tissue disorder may have abnormalities of autonomic functioning of esophageal motor activity.
