Maybe not: Typically, diabetic vascular disease involves the microscopic blood vessels of the foot, so even in the event more blood flow gets to the foot, it can't get through the obstructed outflow that occurs in these tiny blood vessels. This is one reason why bypass won't work in some diabetics. Smoking cessation is also very important, as is tight control of blood sugar. Hope this helps!

You don't: Gangrene is dead tissue. If there is gangrene of the toe, that part of the toe is gone. If there is poor blood flow to the leg, there are techniques to improve flow, starting proximally and going toward the foot. These may or may not work, but they are designed to limit the level of an amputation.

Unreconstructible: This situation is what vascular surgeons call unreconstructible: the small arteries in the calf and foot are too small or obstructed to allow a bypass and conventional angioplasty may not work. Sometimes there is no way to restore blood flow but some surgeons and angiologists have had success at opening up these small vessels with angioplasty. Get another opinion from another expert
