The current state of endovascular intervention for critical limb ischemia: A systematic review

Abstract

The treatment of critical limb ischemia (CLI) has long been a “hot spot” in medical science. It is widely believed that revascularization is the cornerstone of CLI therapy. However, there is currently no consensus on the best revascularization approach. Traditional open surgery is traumatic and associated with many complications. In recent years, great progress has been witnessed in terms of endovascular technology, gradually replacing open surgery in the treatment of CLI. In this review, the role of endovascular therapies in clinical practice, including conventional percutaneous transluminal angioplasty, bare-metal stent, and innovated drug-coated balloon, drug-eluting stent, bioresorbable vascular scaffold, cutting balloon angioplasty, atherectomy, intravascular lithotripsy, cryoplasty, and percutaneous deep venous arterialization is discussed.
