Almost 90% of strokes are a result of lack of flow or ischemia.
- [Peripheral Arterial Disease (PAD)](https://theocsurgeons.com/peripheral-arterial-disease/): Peripheral arterial disease is a chronic disease of the arteries in the legs. PAD occurs over time by way of fatty deposits in your arteries known as atherosclerosis which can narrow the vessels over time. As this occurs you can experience a mismatch of supply and demand between oxygen delivery and the demand of your tissues. This may cause pain with walking known as claudication. If the disease should progress for a variety of reasons and risk factors, you may develop pain all the time or wounds that don’t heal (chronic limb threatening ischemia or CLTI). CLTI patients are at risk for amputation or even death from the effects of vascular disease.
