Where are ischemic ulcers more likely to be found?

• A. On the feet and ankles
• B. Digits and bony regions
• C. On the thighs and calves
• D. In the abdominal area

Answer: (B)

Ischemic ulcers are typically associated with inadequate blood flow to the affected areas, often resulting from underlying vascular conditions such as peripheral artery disease. They develop in regions with the highest risk of ischemia, which generally includes areas of thin skin or where external pressure can reduce blood supply. The digits, or toes, are particularly prone to ischemic ulcers because they are furthest from the heart, making them more vulnerable to reduced blood perfusion. Similarly, areas over bony prominences may experience increased pressure and friction, which can exacerbate the vulnerability of the skin and underlying tissues, leading to ulcer formation. While ulcers can potentially develop in the feet and ankles, as well as the thighs and calves, the digits and bony regions are especially susceptible due to their anatomical characteristics and the typical causes of ischemia. The abdominal area, on the other hand, is less frequently associated with ischemic ulcers, as ulcers in this region are generally linked to different pathophysiological processes, such as pressure ulcers or infections rather than ischemia. Thus, the likelihood of ischemic ulcers is greatest in the digits and bony regions because of their specific risk factors related to blood flow and tissue vulnerability.
