Recanalization of Total Occlusion of the Superficial Femoral Artery and Profunda Femoris Using the Transcollateral Approach

Chronic total occlusions (CTOs) are seen in 30%-40% of symptomatic superficial femoral artery (SFA) disease. Despite advances in revascularization techniques, 10%-20% of these occlusions cannot be crossed. We report 1 case and review the literature on transcollateral retrograde crossing of the SFA from the profunda femoris. The procedural steps and devices (wires and crossing catheters) utilized by various operators are outlined. Based on an overview of current cases in the literature (19 cases, 21 CTOs), success rate was 95.2% with no complications reported. We conclude that transcollateral recanalization of chronically occluded SFA appears to be a viable technique when antegrade access is not feasible.
