Operative treatment for radiation-induced and metastatic brachial plexopathy in 45 cases, 15 having an omentoplasty.

Five cases with metastatic and 40 with metastatic and/or postradiation plexopathy are presented. Metastases and radiation seem to affect equally mostly the lower plexus. Neurolysis with free or pedicled omentoplasty has a positive effect in about 20 percent of cases. Pain relief is more frequently obtained.
