Traumatic brachial plexus complete avulsions and the subsequent formation of pseudomeningoceles are a well-known entity that usually remains asymptomatic. Pseudomeningocele is due to the dural sleeve encasing the damaged roots and the spinal liquid that may accumulate locally or in the supraclavicular soft tissues. The pseudomeningocele, added to the associated lesion of the plexus and usually the surrounding vessels, may become difficult to manage. We describe the novel management of a traumatic pseudomeningocele using an endovascular technique.
