Role of Indocyanine Green in Diagnosing Diabetic Ulcer: A Case Report

Diabetic foot is a syndrome complex that presents with a serious complication arising from a diabetic ulcer. Poor blood circulation and nerve injury (neuropathy), especially in the limbs, can result from persistently elevated blood sugar levels. These elements play an important role in the formation of diabetic ulcers, which frequently occur on the feet and are prone to infection and sluggish healing. These ulcers have the potential to worsen and develop diabetic foot, a more serious ailment if left untreated. Diabetic foot issues can lead to increased vulnerability to infections, gangrene, and in severe cases, amputation. Diabetes patients may fail to notice small wounds or infections because of reduced feeling from neuropathy, which can lead to more serious problems. Moreover, decreased blood flow makes it more difficult for the body to mend itself, which makes diabetic foot issues more difficult to manage and cure. Glycemic management, timely medical intervention, and routine foot care are essential for preventing and lessening the severe effects of diabetic foot. We herein highlight the case of a 57-year-old male with a traumatic diabetic foot in whom indocyanine green (ICG) dye was used to identify the uptake of the involved tissue. The aspect of this case is the late presentation of a patient with uncontrolled diabetes. Further, we can better manage the patient in the preoperative phase by using ICG.
