There is particularly high danger if constricting the carotid artery in the neck, as the brain is sensitive to hypoxia and brain damage can result within minutes of application of pressure. Pressure on the carotid artery can also cause vagal tone induced bradycardia, which can eventually stop the heart.
Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable.

Although the exact mechanism for Harlequin syndrome is still unclear, understanding what is affected with this syndrome is important. The majority of cases are thought to occur when nerve bundles in the head and neck are injured. Such bundles are able to send an action potential from the autonomic nervous system to the rest of the body.
