Abstract
Recently, there has been significant progress in finalizing devices for lower extremity artery disease. Especially in the region of the superficial femoral artery, it is possible to benefit from drug technology. It is necessary to select a device that is appropriate for the lesion, lesion length, and patient background. On the other hand, there are still issues in the treatment of chronic limb ischemia and below-the-knee arteries. In the first place, the pathologies of “above the knee” and “below the knee” are different, and the purpose of treatment is also different. Access sites for treatment have also become smaller and more diverse with the development of peripheral devices.
