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.

After severing the cervical sympathetic trunk, the cells of the cervical sympathetic ganglion undergo transneuronic degeneration

Dopamine beta-hydroxylase deficiency

Dopamine beta-hydroxylase deficiency is a very rare
form of primary autonomic failure characterized by a
complete absence of noradrenaline and adrenaline in plasma
together with increased dopamine plasma levels resulting from
heterogenous molecular alterations of DbH gene.
DbH deficiency is characterized by by cardiovascular disorders
and severe orthostatic hypotension.
Children with DbH deficiency often exhibit reduced ability to exercise
because of blood pressure inadaptation with exertion and syncope.
Symptoms usually worsen during adulthood with severe orthostatic
hypotension, eyelid ptosis, nasal stuffiness and sexual disorders.
