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
After severing the sympathetic trunk, the cells of its origin undergo complete disintegration within a year.

Supersensitivity to noradrenaline and chronic neuropathic pain conditions

Supersensitivity to noradrenaline contributes to certain vascular disorders (e.g., hypertension) and chronic neuropathic pain conditions (e.g., complex regional pain syndrome). We aimed to develop a procedure for inducing adrenergic supersensitivity that could be used to investigate the role of catecholamines in these clinical conditions.
These observations indicate that prolonged depletion of adrenergic stores by guanethidine induces adrenergic supersensitivity in cutaneous vessels, and that adrenergic supersensitivity enhances thermal hyperalgesia in the presence of noradrenaline.
