<unk>  <unk>  consists of a group of distinct disorders that affect the nerves in the brachial plexus (nerves that pass into the arms from the neck) and various nerves and blood vessels between the base of the neck and axilla (armpit).  While traditionally thought of as a sensory-motor neurovascular disorder that is due to a mechanical or compressive source clinical evidence also exits that suggests the sympathetic portion of the nervous system is frequently involved. This is at least one explanation for the poor outcomes seen with a surgical treatment approach.
