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 results in a pronounced increase of cerebrospinal fluid production

Electrical stimulation of the sympathetic nerves, which originate in the superior cervical ganglia, induces as much as 30% reduction in the net rate of cerebrospinal fluid (CSF) production, while sympathectomy results in a pronounced increase, about 30% above control, in the CSF formation. There is strong reason to believe that the choroid plexus is under the influence of a considerable sympathetic inhibitory tone under steady-state conditions.

"Lumbar sympathectomy/Sympathectomy and Hydrocephalus sharing one common finding"

DiagnosisPro is a medical expert system.[1] It provides exhaustive diagnostic possibilities for 11,000 diseases and 30,000 findings.[2] It is supposed to give the most appropriate differential however this is not always the case.[3] Between Oct 2008 and Oct 2009 the site averaged 61,000 visits per month.

Hydrocephalus also known as "water in the brain," is a medical condition in which there is an abnormal accumulation of cerebrospinal fluid (CSF)

Effect of ganglion blockade on cerebrospinal fluid norepinephrine

Prevention of ganglion blockade-induced hypotension using phenylephrine did not prevent the decrease in CSF NE caused by trimethaphan, and when phenylephrine was discontinued, the resulting hypotension was not associated with increases in CSF NE. The similar decreases in plasma NE and CSF NE during ganglionic blockade, and the abolition of reflexive increases in CSF NE during hypotension in ganglion-blocked subjects, cast doubt on the hypothesis that CSF NE indicates central noradrenergic tone and are consistent instead with at least partial derivation of CSF NE from postganglionic sympathetic nerve endings.
