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.

Another case of disabled thermoregulation and heatstroke following sympathectomy

We describe an extreme case of compensatory truncal hyper- hidrosis and anhidrosis over the head and neck region which led to a heatstroke. 

 Six months after the initial operation, he had an episode of heatstroke while perform- ing outdoor duties which required running for around 5 km. The temperature on the day was between 30–32°C, and the relative humidity was between 75 and 85%. At that time, he complained of light-headedness, ‘feeling’ that heat could not dissipate from his head and neck region and muscle cramp in his legs. He was transferred to a hospital and was found to have a body tem- perature of 40°C and shock. His presentation was similar to a previous report by Sihoe et al. [1] on a patient with post- sympathectomy heatstroke. He was subsequently successfully treated with fluid and electrolyte resuscitation and supportive care.
