Retrograde transpedal stenting of the tibioperoneal trunk in critical limb ischemia.

Management of critical limb ischemia (CLI) requires a combined treatment approach: optimal medical therapy and revascularization procedures are both essential for favorable outcome. With the development of endovascular interventions these new modalities took the primary role in limb revascularization, especially in CLI patients, where the culprit lesion is often located below the knee (BTK) level, making the surgical procedure unfeasible. In our present case report, we demonstrate a successful percutaneous recanalization of a surgically non-treatable tibioperoneal trunk occlusion. The procedure was performed with dual access from anterograde and retrograde transpedal approach, and modified "V stenting" technique was used. We describe feasibility of bail out stenting using retrograde posterior tibial artery access after failed retrograde guidewire externalization. Our report discusses the feasibility, safety, and efficacy of the retrograde approach applying 4F compatible devices.
