What physical examination finding is expected in an 81-year-old patient with chronic arterial insufficiency?

In an 81-year-old patient with chronic arterial insufficiency, the expected physical examination finding is thin, shiny, atrophic skin. This occurs due to decreased blood flow and oxygen delivery to the tissues, which leads to significant changes in the skin’s texture and appearance. Chronic arterial insufficiency results in inadequate perfusion, causing the skin to become less nourished.

As the condition progresses, patients may experience atrophy of the skin, making it appear thinner and more fragile. Additionally, the absence of adequate blood flow leads to a decrease in hair growth and the development of shiny skin in affected areas, often seen on the legs and feet. The combination of these findings is characteristic of chronic arterial insufficiency and signals the long-term effects of poor circulation.

In contrast, normal pulsation would typically indicate adequate arterial supply, and normal temperature might not be expected in cases of impaired circulation, where the skin may often be cool to the touch. Marked edema is more commonly associated with venous insufficiency rather than arterial insufficiency, as chronic arterial disease usually leads to fewer signs of swelling due to reduced blood flow. Thus, the thinning and shininess of the skin is a hallmark of this condition.
