Figure 5From: Microdialysis assessment of peripheral metabolism in critical limb ischemia after endovascular revascularization Lactate and pyruvate curves in the ischemic limb of a single patient. After the first attempt of revascularization (arrow), lactate decreased. After a short period, lactate started to rise again (sketched arrow): this patient experienced a recurrent thrombosis of the treated arterial district, and finally underwent major amputation.Back to article page
