Appropriate care in chronic limb threatening ischemia: A review of current evidence and outcomes.

ABSTRACT

Chronic limb threatening ischemia (CLTI) poses a significant treatment challenge for vascular surgeons, interventionalists, podiatrists, and associated medical specialists. The evidence for what constitutes appropriate care is rapidly evolving and new treatment options are in constant development. This review examines the current guidelines for CLTI care, as well as reported outcomes for multiple care strategies in this patient population, including revascularization and medical optimization. We performed a literature review of the PubMed database, reviewing articles that reported outcomes for CLTI care between 2000 and 2023, and described these outcomes as they relate to the current state of CLTI treatment. Significant data are still forthcoming regarding CLTI care, but widespread adoption of appropriate CLTI care is essential for the treatment of this vulnerable population.
