    Abstract:
    Increasing the primary success rate in recanalization of peripheral vascular occlusions is one aim of using laser techniques in the treatment of peripheral vascular disease. Although reports of lasers enabling recanalization after failure of guide wires have been numerous, direct comparisons of the success of the two techniques in a randomized trial have been few. The results of a randomized trial showed no statistical difference in recanalization of femoropopliteal occlusions between the conventional guide wire and hybrid laser probe. The number of patients with iliac occlusions was small and comparisons are difficult to make, but the findings suggest that the hybrid laser probe has little to offer. Immediate crossover to the alternative method allowed investigation of the relationship between the two methods in practice. Combining the two methods improved the primary success rate from 82% to 91% for femoropopliteal occlusions randomized to laser thermal recanalization and from 74% to 91% for those randomized to conventional recanalization.
