National Utilization and Outcomes of Redo Lower Extremity Bypass versus Endovascular Intervention after a Previous Failed Bypass

In this large national sample representing routine vascular care of patients with CLI after failed ipsilateral LEB of the same arterial segment, IEI is common and represents 30% of revascularizations in this data set. Redo LEB with saphenous is associated with superior limb-related outcomes, but IEI offers an acceptable potential alternative to bypass in patients who would require alternative conduit. Finally, perioperative care is critical as we demonstrate that patient comorbidities, not the method of revascularization, predicted MACE.
