Rupture of an abdominal aortic aneurysm is a vascular emergency that involves a tear in the weakened artery wall, leading to rapid internal bleeding into the abdomen or retroperitoneal space. This causes abrupt onset severe abdominal or back pain, possible tearing sensation, and signs of hypovolemic shock as blood loss progresses. Because the bleeding is rapid and the patient can deteriorate quickly, this is a life-threatening situation that requires immediate surgical control of the bleeding. The description that the aneurysm remains intact during rupture is contradictory to the event itself. The notion of only mild symptoms underestimates the abrupt and severe presentation that often accompanies ruptured AAA. And stating it is never life-threatening is clearly incorrect given the high mortality associated with delayed or absent surgical intervention. In practice, suspected rupture calls for rapid assessment, securing airway and circulation, two large-bore IVs, prompt fluids or blood products as indicated, and urgent transport to a facility capable of emergent vascular repair.
