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.

abnormal peripheral vascular responses to temperature

thoracic sympathectomy has been demonstrated to abolish or alter sympathetic vasoconstrictive responses in the skin, and this may contribute to abnormal peripheral vascular responses to temperature [4]. Paradoxically it has been suggested that in some cases there may be abnormal vasoconstriction rather than the expected vasodilatation after sympathectomy [5]. It is not impossible that such atypical peripheral vascular responses to rising body temperature may have contributed to impaired heat loss during exercise or to an inappropriate response to shock on the development of the heat stroke.
