Abstract |
Many gunshot wounds (GSW's) to the brachial plexus do not improve spontaneously with time and are therefore candidates for surgery. Over an 18-year period, 141 patients with GSW's were evaluated, 90 of whom were operated on; 75 of the surgical cases were followed for 2 years or more. Thirty operative patients had initial vascular repair, while eight required thoracotomies. Total plexus palsy was present in 19 of those selected for operation. The average interval between injury and operation was 17 weeks. Six patients required early operation for an expanding aneurysm with progressive neural loss. Persistent complete loss of function in the distribution of one or more elements and/or noncausalgic pain not managed by medications provided the major operative indications. Four patients required sympathectomies for causalgia. Of 166 lesions in continuity believed to be complete, based on clinical examination and electromyography, 48 with preserved intraoperative nerve action potentials (NAP's) were spared resection or were treated with a split repair with excellent eventual results on a weighted grading system. By comparison, only seven of 55 elements believed to have incomplete loss or to be recovering did not have NAP's and required repair. Fifty-three of 98 lesions repaired by grafts and 18 of 26 wounds with suture repair recovered to a Grade 3 level or better. Most elements were in continuity but 14 were found "blown apart" and required repair, usually by grafting. The best outcome was achieved with upper trunk and lateral and posterior cord lesions, but recovery occurred with some C-7 to middle trunk and medial cord to median repairs. Language: en |
