Mononeuropathies associated with orthotopic liver transplantation were
evaluated in a prospective manner. Ten percent of liver transplant re
cipients were noted to have focal peripheral nerve lesions in the post
operative period. The ulnar nerve was most commonly involved, with int
raoperative compression or postoperative trauma as possible mechanisms
of injury. Other upper extremity mononeuropathies were likely a resul
t of vascular cannulations. No brachial plexus injuries occurred. Diab
etes and alcoholism were not risk factors for the development of a mon
oneuropathy. (C) 1998 John Wiley & Sons, Inc.
