RESUMO
PURPOSE: To describe a novel technique for percutaneous retrograde access of the tibial vessels after antegrade access failure in patients with chronic limb-threatening ischemia. METHODS: Six patients who had failed antegrade access to infrapopliteal occlusions had attempted retrograde tibial puncture and wire passage into the proximally patent vessel. Endovascular intervention was carried out utilizing standard techniques. The patients were followed for functional class and wound healing. RESULTS: All six patients were successfully recanalized. Five patients experienced rapid and dramatic healing of wounds that had previously been refractory to conservative therapy. The other patient did not experience healing and ultimately died of progressive intractable congestive heart failure in the setting of a severe ischemic cardiomyopathy. CONCLUSIONS: Retrograde tibial access can be a valuable technique in the armamentarium of a peripheral interventionist treating patients with chronic critical limb ischemia.
