Anemia is not known to cause intermittent claudication. We herein present the case of a 74-year-old male patient with intermittent claudication, in whom the primary symptom was severe iron-deficiency anemia. The characteristics of claudication mimicked a neurogenic disorder, but lumbar magnetic resonance imaging ruled out lumbar spinal stenosis, and the symptoms resolved after the anemia improved. This case highlights the need to consider anemia in the differential diagnosis of patients presenting with intermittent neurogenic claudication. A comprehensive evaluation, including tests to rule out anemia, is crucial for making an accurate diagnosis and carrying out the appropriate management of intermittent claudication.

Background: Peripheral artery disease (PAD) is widely prevalent, affecting more than 200 million people worldwide. However, the natural history of this disease process following lower extremity revascularization has not been fully delineated. We aimed to analyze this disease process with particular attention to subsequent interventions, wound complications, and mortality.

The use of questionnaires in vascular rehabilitation has increased. The Walking Impairment Questionnaire (WIQ) can identify functional risk due to peripheral arterial disease (PAD). This study aimed to assess the accuracy of the WIQ for identifying individuals with PAD and intermittent claudication with low functional capacity.

The femoropopliteal segment is a common anatomic location for peripheral artery disease. The clinical presentation of occlusive disease of the femoropopliteal segment can range from symptomatic or severe claudication if in isolation, or acute or chornic limb threatening ischemia often in the setting of multilevel disease. Patients can be treated with various therapies to improve symptoms and restore perfusion, including medical, exercise, endovascular, and open surgical therapies.
