This issue starts with the state of the art review of surgical revascularization techniques for diabetic foot by Dr Sunil Kota. Diabetes is a common disease affecting millions of people worldwide. Diabetic foot wounds are responsible for 5–10% of the cases of major or minor amputations. Revascularization using techniques including surgical bypass, angioplasty, a combination of the two procedures and subintimal recanalization has been used for salvaging ischemic limb. In this informative review, Dr Kota described in detail how to differentiate the ischemic vs non ischemia diabetic foot using a combination of clinical evaluation, imaging and functional approaches. The indications of revascularization, and details of each surgery approaches are also provided. We highly recommend the readers to apply information from this review to guide our care of our diabetic patients.
