What is the chief complaint (CC) for a patient suspected to have an abdominal aortic aneurysm (AAA)?

In the case of a suspected abdominal aortic aneurysm (AAA), the chief complaint typically experienced by patients is midline abdominal pain. This pain is often described as a deep, constant ache that can vary in intensity. As the aneurysm grows, it can exert pressure on surrounding structures, leading to discomfort or pain in the abdominal area.

While a pulsatile abdominal mass is an important clinical finding often associated with AAA, it is typically assessed during a physical examination rather than reported as a primary complaint by the patient. Chest pain is more indicative of thoracic issues, and back pain radiating to the legs can be attributed to various conditions but is less specific to AAA. Therefore, midline abdominal pain is the most characteristic and prominent symptom that aligns closely with the presentation of an abdominal aortic aneurysm, making it the most suitable choice for the chief complaint in this scenario.
