Hepatic myelopathy after splenorenal shunting: report of one case and review of the literature.

Hepatic myelopathy is a rare complication of cirrhosis, usually associated with surgical or spontaneous porto-systemic shunts. Its pathophysiology is unknown. It is characterized by a motor involvement of the lower limbs without clinical sensory abnormality, leading to spastic paraparesis. These neurological features are related to a symmetric loss of myelin in the lateral corticospinal tracts. Usefulness of liver transplantation in this setting is not yet determined. We describe here the case of a 29-year-old male who presented with progressive spastic paraparesis of the lower limbs 3 years after a spleno-renal shunt.
