Definition, Etiology, PathogenesisTop
Aortic pseudoaneurysm refers to disruption of all aortic wall layers that does not lead to fatal exsanguination thanks to periaortic connective tissue.
1) Blunt thoracic trauma in motor vehicle accidents (impact of safety belts, motor bike crashes), falls, sports injuries.
2) Iatrogenic: Aortic surgery, percutaneous catheter-based interventions.
3) Rarely, due to aortic infection or penetrating aortic ulcer.
An increase in blood pressure may cause an aortic pseudoaneurysm to rupture and result in fatal hemorrhage. In some patients aortic pseudoaneurysms may be an incidental finding.
Invasive treatment (endovascular or surgical), regardless of the size of the pseudoaneurysm.
Pseudoaneurysm rupture; fistula and compression of the surrounding structures, which leads to their destruction.
