The Role of Endovascular Procedure for Peripheral Arterial Disease in Diabetic Patients With Chronic Limb-Threatening Ischemia

Type 2 diabetes mellitus is a major risk factor for all forms of cardiovascular diseases, including peripheral arterial disease (PAD). Chronic limb-threatening ischemia (CLTI) is determined by the presence of ischemic rest pain, and may or may not be accompanied by tissue loss (such as ulcers and gangrene) or infection. Treatments for CLTI consist of wound treatment, infection control, and ischemia control by arterial revascularization, which can be performed by either open surgical procedure (bypass) or an endovascular approach. We present two cases of chronic limb-threatening ischemia, one with an above-knee lesion and the other with a below-knee lesion. In addition to good wound treatment and glucose control as the risk factor management, we performed endovascular therapy in both patients. Both patients showed good wound improvement after the procedure.
