Objective: To evaluate the efficacy of various strategies for revascularization of chronic total occlusion of femoropopliteal arteries when the guide wire does not pass in an anterograde direction.
Materials and Methods: Twenty-four patients with totally occluded femoropopliteal arteries (mean occlusion length 13.75 cm; range, 6-22 cm) were treated by using a retrograde approach and two novel catheters. After successful recanalization or reentry, balloon angioplasty followed by stent placement was performed to complete the revascularization.
Results: In 16 cases in which to cross the occlusion via intraluminal or subintimal route was failed, we used Frontrunner catheters in five cases and Outback catheters in 11 cases. In eight cases in which to reenter after subintimal passage of the guide wire was failed, we used Outback catheters. Successful recanalization was achieved intraluminally or subintimally in all cases. One perforation occurred during subintimal passage of the guide wire that was controlled by recanalization of another subintimal tract. There were no cases of distal thromboembolism or other complications.
Conclusion: A retrograde approach and using the Frontrunner and Outback catheters are safe and effective for successful revascularization of chronic total occlusion of femoropopliteal arteries. In particular, they are useful when the initial antegrade attempts at recanalization have failed.
