Strategies to Approaching Lower Limb Occlusions.

Endovascular management of chronic total occlusions (CTO) can be challenging both from decision-making and technical perspectives. Successful treatment and management of a CTO requires the operator to have an understanding of the salient imaging findings, a thorough knowledge of the various technical challenges of the procedure, and comprehension of the importance and necessity of long-term clinical management. This article outlines a general approach to endovascular management of lower limb CTOs and discusses indications, techniques, potential complications, and therapeutic options of the procedure.
