{Abstract}: Treatment of lower limb ischemia in patients with diabetes is challenging because of the location of the ulcers and the complexity of their pathogenesis. Carbon dioxide fractional laser (CO2FL) therapy in conjunction with tibial periosteum distraction could become a substitute for conventional methods. We herein describe a patient diagnosed with ischemic diabetic foot with a complex ulcer in the upper third of the tibia. Laser irradiation (Deep FX mode with 30 mJ of energy and 10% density) was applied to the entire region of skin below the knee after surface anesthesia, and this treatment was performed twice a week until the ulcer healed. Computed tomography angiography showed successful establishment of a blood supply to the back of the right foot after treatment. Skin grafting was successfully performed, with only a few wounds remaining on the foot 8 months after treatment. The pain score was significantly decreased at the last follow-up. No complications occurred. This case report provides guidance for the performance of CO2FL, a fast, easy, accurate treatment in patients with diabetes. CO2FL can target lower limb arterial occlusive disease accompanied by refractory ulcers, addressing the underlying vascular occlusion and dysfunction as well as promoting microcirculation and wound healing.
