DREZ

Dorsal root end zone Neurology A CNS pathway that may be surgically sectioned to relieve chronic pain–eg, anterolateral cord and trigeminal tract; DREZ lesions are produced by thermal coagulation or laser, and relieve 65-70% of intractable pain associated with brachial and lumbar plexus avulsion and spinal cord trauma

Dorsal root entry zone (DREZ)

A type of nerve surgery for postherpetic neuralgia that is occasionally used when the patient can get no other pain relief. The surgery destroys the area where damaged nerves join the central nervous system, thereby interfering with inappropriate pain messages from nerves to the brain.

The comorbidities should be treated aggressively and therapy for spasticity, such as DREZ lesioning or intrathecal baclofen therapy, can be used with great success to improve the quality of life and improve function.
La primera indicacion establecida para la tecnica DREZ fue la deaferentacion en pacientes con avulsion del plexo braquial.
Asi mismo, se puede deducir que el dolor infrasegmentario sigue siendo un desafio terapeutico y que la eficacia del manejo con lesion DREZ es muy variable, lo cual tiene una directa relacion con la incompleta determinacion de su fisiopatologia, que ha sido motivo de especulacion.
