This document summarizes key points from a presentation on treating chronic critical limb ischemia. It discusses the benefits of revascularization over amputation for patient survival. Bypass surgery using the saphenous vein has better outcomes than prosthetic grafts, especially below the knee. Endovascular techniques have improved but primary patency remains lower than bypass. The BASIL trial found initial bypass surgery led to better amputation-free survival compared to initial angioplasty. The concept of angiosomes provides a framework for endovascular revascularization but published data on outcomes based on direct versus indirect angiosome targeting is limited.
