Which symptom is NOT commonly found in cases of acute arterial occlusion?

In cases of acute arterial occlusion, symptoms arise from the sudden interruption of blood flow to a limb, which can lead to serious consequences if not addressed promptly. Among the typical symptoms associated with acute arterial occlusion are paresthesia, paralysis, and pulselessness. Paresthesia refers to abnormal sensations such as tingling or "pins and needles," which occur due to nerve ischemia. Paralysis can result from a lack of blood supply to the muscles, impairing their ability to function. Pulselessness indicates the absence of detectable arterial pulse in the affected limb due to the blocked blood flow.

The presence of pedal ulcers, however, is not a common symptom of acute arterial occlusion. Pedal ulcers typically develop as a result of chronic conditions, such as peripheral arterial disease, where there is long-term inadequate blood flow leading to ischemia, tissue necrosis, and ultimately ulceration. Since acute arterial occlusion presents suddenly and is characterized by the immediate cessation of blood flow, the development of ulcers is not associated with this acute event. Thus, the correct choice is that pedal ulcer is not commonly found in cases of acute arterial occlusion.
