Aortic pseudoaneurysm

Aortic pseudoaneurysms typically occur as a result of trauma. They can be acute or chronic.

Aortic pseudoaneurysms are contained ruptures of the aorta in which the majority of the aortic wall has been breached, and luminal blood is held in only by a thin rim of the remaining wall or adventitia.

They typically occur from focal aortic transection of which 85% are the result of penetrating trauma (gunshot or stab wounds) and 15% of cases and blunt trauma (motor vehicle accidents or falls). They also occur from non-traumatic pathologies such as penetrating atherosclerotic ulcers 5.
