Critical limb ischemia (CLI) is a severe form of peripheral arterial disease (PAD) marked by ischemic rest pain, tissue loss, or gangrene. CLI is associated with significant morbidity, mortality, and resource utilization. Patients can be treated with revascularization, either surgical or endovascular. To help clinicians, patients, and policymakers decide between surgery-first and endovascular-first approaches in patients with CLI, we were asked to conduct a systematic review of the literature.
KQ1: Among adults with CLI, what is the cost-effectiveness of leg bypass compared to endovascular procedures including balloon angioplasty, arterial stents, and atherectomy?
KQ2: Does the cost-effectiveness of leg bypass compared to endovascular procedures for CLI vary by patient population, setting, or time (short vs long-term)?
