Patient: My mother is an insulin diabetic and also has renal failure (kidney disease and high blood pressure). She has already lost part of her right leg, (below the knee) and now is in danger of losing the other foot, due to poor circulation. Her doctors have performed an angiogram, but are doubtful that a by-pass will work, as her arteries are severely damaged two thirds down the leg. She now has two ulcers on the left foot and is in tremedous pain. Could you please provide a solution for saving this foot? I’m desperate for an answer.
