LIMB ARTERIAL INJURIES ASSOCIATED WITH LIMB FRACTURES - CLINICAL PRESENTATION, ASSESSMENT AND MANAGEMENT

Objectives: Review of limb arterial injuries associated with limb fractures. Design: Retrospective study. Setting: University Hospital. Materials and Methods: The clinical presentation, assessment and management of 25 patients with upper (seven) and lower (18) limb arterial injuries associated with limb bone fractures has been retrospectively reviewed. Main Results: Five patients presented with life threatening injuries and classic signs of acute limb ischaemia, 15 patients had an obvious limb arterial injury, and 5 presented with a suspected limb arterial injury. The site of arterial damage was: superficial femoral (4); popliteal (11); tibioperoneal trunk (3); anterior tibial (4); posterior tibial (3); peroneal (2); axillary (1); brachial (5); radial (4); and ulnar artery (4). The types of arterial repair were: autogenous vein interposition or bypass grafting (17); P.T.F.E. (2); end-to-end anastomosis (14); and ligation (8). The popliteal vein was injured in six cases, repaired in four and ligated in two; the superficial femoral vein was injured in four cases, repaired in three and ligated in one; and the axillary vein was injured in one case and was ligated. Primary nerve repair was employed in six out of seven injured nerves. Skeletal fixation preceded vascular repair in 21 patients with lower limb ischaemia. Completion arteriography revealed residual thrombi in the distal foot of four patients, in whom intraarterial thrombolysis was effective. During the follow-up period of 1.5 to 2 years, the upper and lower limb preservation rate was 100 and 89%, respectively. The upper limb function was judged excellent in five patients, good in one and fair in one. In the lower limbs it was excellent in 11 patients, good in three, fair in one and poor in one. Conclusions: To ensure life and functional limb salvage of patients with devastating vascular injuries, a well organised multidisciplinary approach is necessary.
