Chronic limb threatening ischemia (CLI) is often associated with occlusive disease of the infrapopliteal arteries. Percutaneous balloon angioplasty has been a standard treatment modality for infrainguinal arterial occlusive disease, but its use is limited by its relatively high restenosis rate and the frequent need of re-intervention, especially in below-the-knee (BTK) arteries. In the past decade, ongoing technology innovations, such as drug-coated balloon and drug-eluting stents have shown promising results in peripheral arterial disease. Atherectomy, a plaque debulking technology capable of disobliterating heavily calcified vessels, has also been advocated for BTK disease. However there is little in the way of high-quality comparative data to discern the relative efficacy of these interventional approaches versus each other, or versus open surgery. This review provides a current summary of evidence for these technologies in the setting of CLI and BTK occlusive disease.
