How does an abdominal aortic aneurysm affect kidney function?

An abdominal aortic aneurysm (AAA) can affect kidney function primarily through compromised blood flow. As the aneurysm enlarges, it may exert pressure on surrounding structures, including the renal arteries, potentially leading to renal ischemia or reduced blood supply to the kidneys. Additionally, if the aneurysm ruptures, it can cause significant internal bleeding, further impairing kidney perfusion and function. Prompt diagnosis and management are essential to prevent these complications.
