Medical and surgical considerations in patients with vasculitis and Raynaud's syndrome.
Vascular problems in the foot are certainly common when one considers only arteriosclerosis on the macrovascular scale. The primary cause of ischemia of the foot undoubtedly is primary arteriosclerosis, whether related to smoking, diabetes, renal failure, or other causes. Vasculitis and vasospasm, in their many forms, are distinctly unusual as a cause of ischemia of the foot. These entities, nonetheless, can cause significant problems from the standpoint of symptoms and even ulceration or gangrene of the foot. This article addresses the pathophysiology of vasculitis and vasospastic problems in the foot and their management.
