Objective To investigate the application of staged endovascular treatment to high-risk patients with critical limb ischemia (CLI). Methods From September 2013 to March 2015, a total of 16 patients with CLI (both iliac artery and distal arterial occlusion, TASC-ⅡD) underwent the staged endovascular angioplasty. Clinical data of patients were collected and retrospectively analyzed. The average follow-up period was 7.8 months. Results The technical success was achieved for all patients. The rest pain of patients disappeared after the first endovascular treatment with no amputation and serious complications. During two treatments, the difference of the ankle brachial index (ABI) before and after surgery was statistically significant (P=0.000). Conclusion The staged endovascular technology can effectively alleviate the symptoms of rest pain and tissue necrosis of high-risk patients with CLI, avoid serious complications such as the ischemia reperfusion injury and acute cardiovascular events caused by unstaged endovascular treatment, and improve the life quality of patients.
