Bypass Surgery Versus Endovascular Therapy in Chronic Hemodialysis Patients With CLI Due to Infrainguinal Disease

Although lower limb revascularization has been commonly performed to treat critical limb ischemia (CLI) in patients with chronic kidney disease, the clinical outcomes such as limb salvage or survival rate have been reportedly poorer compared with those without chronic kidney disease after both bypass surgery and endovascular therapy (EVT) (1,2). On the other hand, it remains unclear which procedure should be optimized to treat CLI. The BASIL (Bypass Versus Angioplasty in Severe Ischemia of the Leg) trial (3) revealed that the outcomes after 2 procedures were broadly similar in the general population. However, there have been limited data regarding such comparison in patients on hemodialysis (HD). We investigated long-term clinical outcomes after bypass surgery or EVT in HD patients with CLI due to infrainguinal disease.
