Retrograde Guidewire-Assisted Remodeling Technique: A Novel Technique for Endovascular Recanalization of Occluded Arterial Origins in Critical Limb Ischemia.

In the CLI, results of this trial suggest that REGART is feasible, effective, and with acceptable safety in the catheterization of occluded artery origins without a visible stump when conventional anterograde and retrograde techniques fail. Thus, the target occluded artery can be recanalized while preserving other arterial origins by minimizing dissection risk through subintimal balloon angioplasty at the bi-trifurcation level.
