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.

Sympathectomy alters acetylcholinesterase expression

Acetylcholinesterase was analysed after destruction of adrenergic nerves by 6-hydroxy-dopamine or bilateral stellate sympathectomy. Effectiveness of treatment was verified by determining noradrenaline concentrations in right ventricle. Acetylcholinesterase activity was assayed in homogenates of atria and portions of left ventricular free wall.

Sympathectomy caused a small decrease in acetylcholinesterase activity, due to a decrease in the activity of the tetrameric globular form of the enzyme. Choline acetylcholinesterase activity was not altered by sympathectomy, which is an indication that cholinergic nerves were not affected.

Conclusions – The contribution of adrenergic neurones to the cardiac pool of acetylcholinesterase is measurable and consists primarily of the tetrameric globular form of the enzyme.
