Mononeuropathies associated with liver transplantation.

Mononeuropathies associated with orthotopic liver transplantation were evaluated in a prospective manner. Ten percent of liver transplant recipients were noted to have focal peripheral nerve lesions in the postoperative period. The ulnar nerve was most commonly involved, with intraoperative compression or postoperative trauma as possible mechanisms of injury. Other upper extremity mononeuropathies were likely a result of vascular cannulations. No brachial plexus injuries occurred. Diabetes and alcoholism were not risk factors for the development of a mononeuropathy.
