Can agent orange cause an abdominal aortic aneurysm?

Yes, agent orange can cause an abdominal aortic aneurysm (AAA). Agent orange is a herbicide and defoliant that was used by the United States military during the Vietnam War. It is a mixture of two chemicals, 2,4-D and 2,4,5-T. Studies have found that exposure to agent orange can increase the risk of AAA, particularly in individuals who were exposed to high levels of the herbicide. The mechanism by which agent orange causes AAA is not fully understood, but it is thought to be related to the toxic effects of the chemicals on the blood vessels.
