Endovascular therapy for critical limb ischemia

: Bypass surgery is still considered the "gold standard" therapy for the treatment of critical limb ischemia (CLI). However, due to recent advances in endovascular technologies, catheter-based intervention has become a viable option, and percutaneous treatment is becoming more widely used. This paper provides a brief overview of the percutaneous therapies available today and new technologies on the horizon as well as highlights some advantages and limitations of each treatment option in CLI.
