This document discusses aortic aneurysms, including their incidence, etiology, pathological changes, classification, clinical features, diagnostic measures, complications, and management. Aortic aneurysms are caused by damage to the aortic wall from trauma, infection, or intrinsic defects that lead to progressive destruction of proteins and weakening of the vessel wall. If untreated, the bulging vessel wall risks rupture from increased blood pressure, which can cause death. Diagnostic measures include imaging tests to detect the aneurysm, while management involves surgical procedures to repair or replace the damaged vessel section.Read less
