Complex regional pain syndrome (CRPS type 1 and type 2), sometimes referred to by the hyponyms reflex sympathetic dystrophy (RSD) or reflex neurovascular dystrophy (RND), is a rare and severe form of neuroinflammatory and dysautonomic disorder causing chronic pain, neurovascular, and neuropathic symptoms.
This includes two separate types: type I and type II. Type I CRPS, formerly known as reflex sympathetic dystrophy (RSD) or "Sudeck's atrophy", refers to CRPS without any observed nerve damage. Type II, formerly known as causalgia, refers to CRPS with observed nerve damage. This form, similarly to other forms of AMPS, is known to be able to ...
Endoscopic thoracic sympathectomy (ETS) is a surgical procedure in which a portion of the sympathetic nerve trunk in the thoracic region is destroyed. [1] [2] ETS is used to treat excessive sweating in certain parts of the body (focal hyperhidrosis), facial flushing, Raynaud's disease and reflex sympathetic dystrophy.

The stellate ganglia may be cut in order to decrease the symptoms exhibited by Raynaud's phenomenon and hyperhydrosis (extreme sweating) of the hands. Injection of local anesthetics near the stellate ganglion can sometimes mitigate the symptoms of sympathetically mediated pain such as complex regional pain syndrome type I (reflex sympathetic dystrophy), and symptoms associated with alterations ...
Reflex activation then results in systemic vasoconstriction below the spinal cord disruption. This peripheral arterial vasoconstriction and hypertension activates the baroreceptors . There is a resultant parasympathetic surge originating in the central nervous system which inhibits the sympathetic outflow.
Reflex syncope can occur in otherwise healthy individuals, and has many possible causes, often trivial ones such as prolonged standing with the legs locked. [ citation needed ] The main danger of vasovagal syncope (or dizzy spells from vertigo) is the risk of injury by falling while unconscious.
