Is Peripheral Arterial Disease reversable?

So peripheral arterial disease is reversible, and I mean that usually you have of course to stage the disease, the amount of the disease, and based on this and on the symptoms of the patient, surgeons and vascular specialists can operate on patients and can restore the patency of the blood flow in the occluded arteries. operation lasts forever, sometimes the operation lasts a few years, sometimes the operation lasts a few days. Of course it depends a lot on how the operation is done but also depends on the amount of the disease that the vessel has and of course on the amount of clinical symptoms like how bad is the tissue loss for example.
