Arterial lesions in osteoarticular trauma of the lower limbs.

OBJECTIVE

To evaluate in-hospital mortality and limb salvage of a series of patients presenting with arterial injury of the lower limbs complicating an osteoarticular trauma, and to determine any preoperative predictive factors of limb salvage.

METHODS

Data of consecutive patients treated between 01/2007 and 12/2017 were retrospectively analyzed. Primary outcomes were in-hospital mortality and limb salvage. Multivariate analysis was performed to assess any variable that could affect limb salvage. P values <0.05 were considered statistically significant.

RESULTS

The postoperative course, death occurred in 2 patients Lower limb amputation was performed in 13 cases (15.6%). The main factors predicting limb amputation were the timing of staged surgery, in particular when bone stabilization was performed first (P<0.001), and a delay Data concerning 74 patients with 83 traumatized lower limbs were analyzed. Most vascular lesions were located at the popliteal artery (47, 63.5%). Surgical bone stabilization was performed as a first step in 45 patients (60.8% of cases), followed by a delayed arterial repair. The median time to revascularization was 14.3 hours (range from 2 hours to 6 days). In 29 patients (39.2%) vascular repair and bone stabilization were performed simultaneously. During to limb revascularization longer than 6 hours (P<0.001). The location of injury at the popliteal artery (P=0.005), the presence of infection (P<0.001), and the severe ischemic signs at presentation (P=0.001) also were factors associated with amputation.

CONCLUSIONS

The timing of staged surgical repair and the revascularization delay were the main predictor factors of limb salvage.
