摘要
Five sheep underwent repair of the median nerve along with the establishment and repair of a brachial artery defect adjacent to the site of nerve injury The defect in the brachial artery was of similar length to the nerve defect and lay in parallel with it. It was repaired using a reversed vein autograft harvested from one of the superficial veins of the arm. A further five sheep underwent similar treatment with the repair of the nerve delayed for 30 days after the establishment of the complicating vascular injury. Six months after the nerve repair, each group of sheep was assessed using electrophysiological and morphometric methods in order to establish objective indices of nerve recovery and regeneration. These results were compared with those from other sheep which had undergone nerve repair both immediate and delayed with no complicating injury and groups in which the complicating injury consisted of a cavity, fibrosis and haematoma, It was found that delay in the nerve repair and the presence of a complicating arterial injury, both separately and additively, contributed to a poorer outcome in recovery of nerve function and maturation. The effect of an arterial injury, in both of these respects, was to produce a worse outcome than the presence of a cavity with fibrosis and haematoma.
