The ulcers are caused by lack of blood flow to the capillary beds of the lower extremities.

[2] In microangiopathy, neuropathy and autoregulation of capillaries leads to poor perfusion of tissues, especially wound base.

Arterial doppler and pulse volume recordings are performed for baseline assessment of blood flow.

The prevalence of arterial insufficiency ulcers among people with Diabetes is high due to decreased blood flow caused by the thinning of arteries and the lack of sensation due to diabetic neuropathy.

Prevention is the first step in avoiding the development of an arterial insufficiency ulcer.

If not taken care of in time, there are very high chances that these may become infected and eventually may have to be amputated.
