Hyperhydrosis in paraplegia

L W Kneisley

    Archives of Neurology
    |September 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    A traumatic thoracic aortic aneurysm led to spinal cord injury, causing paraplegia and abnormal sweating. Recovery included sensory function return and persistent hyperhidrosis, suggesting specific spinal cord lesion mechanisms.

    Area of Science:

    • Neurology
    • Vascular Surgery
    • Trauma Surgery

    Background:

    • A 20-year-old male sustained severe trauma from a motor vehicle accident.
    • The trauma resulted in a dissecting aneurysm of the thoracic aorta, leading to hypotension.

    Observation:

    • Surgical repair involved resection and prosthetic graft replacement of the affected aorta.
    • Postoperatively, the patient developed paraplegia below the T-9 level, with loss of pain and temperature sensation but preserved proprioception.
    • Over nine months, significant sensory recovery occurred in the lower extremities.

    Findings:

    • The patient experienced severe, constant hyperhidrosis below the T-9 dermatome, independent of external stimuli.
    • Hyperhidrosis showed partial response to methantheline bromide treatment.

  • The spinal cord lesion is hypothesized to involve anterior horn cell loss while sparing interneurons and intermediolateral gray columns.

    • Implications:

    • Proposed mechanisms for the observed neurological deficits and hyperhidrosis include disinhibition of sympathetic circuits or axonal sprouting.
    • This case highlights the complex neurological sequelae of traumatic aortic injury and repair.
    • Understanding these mechanisms may inform future treatment strategies for spinal cord injury and autonomic dysfunction.
