Vascular Surgery



A diabetic foot ulcer is an open sore or wound that occurs in approximately 15 percent of patients with diabetes and is commonly located on the bottom of the foot. Foot ulcers are the most common cause of diabetes hospitalizations and amputations. 

People with diabetes have too much glucose, or sugar, in their blood stream and over a long period of time this can lead to damage in the blood vessels. This damage can result in the development of blockages of the arteries in the legs, and those can result in foot ulcers. The damage done by diabetic foot ulcers can be minimized if caught early.
