%X <B>BACKGROUND: </B>Patients with peripheral arterial disease (PAD) have a poorer prognosis than those without PAD. PAD complications worsen the prognosis of patients with chronic kidney disease (CKD), especially those on maintenance dialysis. Although low-density lipoprotein apheresis (LDL-A) is expected to be effective in treating severe PAD, there are no large-scale reports on the prognosis of patients undergoing LDL-A.<BR><B>METHODS: </B>We obtained a clinical database from April 2008 to August 2021 and selected 924 238 patients with CKD. We selected patients with disease codes of lower limb arteriosclerosis obliterans, arteriosclerosis obliterans, and critical limb ischemia or foot ulcer. Patients who were prescribed antithrombotic medications were included. Patients who used steroids were excluded. Among these patients, those undergoing blood purification considered LDL-A were selected, and their current status was investigated.<BR><B>RESULTS: </B>We included 147 patients (113 males and 34 females). The mean patient age was 70 ± 10 years. Diabetes mellitus was present in 86%, ischemic heart disease in 34%, and stroke in 48%. Maintenance dialysis patients accounted for 86% of the patients. Statins were administered to 40% of the patients, and bypass surgery was performed in 2.7%. The median observation period was 812 days, and the mortality rate was 41%.<BR><B>CONCLUSIONS: </B>LDL-A was performed in a small population of patients with CKD with the most severe form of PAD. The prognosis for these patients is extremely poor. Therefore, strategies to improve prognosis are important.
