Potential complications

What are the potential complications of PAD?

If PAD is detected early enough, its progression can be slowed down and even stopped. However, if the risk factors are not addressed, the symptoms or discomfort associated with this disease may become more severe.


Instead of being felt only when walking, pain can occur at rest and even when lying down, at night for example.


If blood flow is limited, even small or minor wounds will not heal at all or only with great difficulty.
If blood flow is severely restricted, sores can appear spontaneously, especially in the extremities, such as the toes and heels.


If the blood can no longer circulate, the extremities (toes, feet, legs) may turn blue and then black. This is called gangrene and, in some cases, amputation may become unavoidable.

Stroke (cerebrovascular accident)

When PAD affects the carotids, the arteries that deliver blood to the brain, a stroke can occur.
