Abstract
Today, catheter-based endovascular therapy is widely accepted as a method to treat critical limb ischemia patients due to its rapid improvement over the last 10 years. New techniques for guidewire maneuvering and distal puncture have been introduced. In addition to these, domestic medical device companies release many new guidewires and micro-catheters that are specialized for peripheral use. These technical and device improvements synergistically strengthen the potential of endovascular therapy. In this article, I will review the current status of endovascular treatment for below-the-knee lesions.
