Aortic arch aneurysm
An aortic arch aneurysm is a less common form of thoracic aortic aneurysm and may account for around 10% of such aneurysms.
There is a recognized male predilection with most patient's presenting around to 6th to 7th decades of life.
It can be clinically silent and can complicated by cerebral injury and / or a catastrophic vascular event especially if it involves vessels supplying to the head, neck, and upper limbs.
As with other thoracic aneurysms, atherosclerosis still remains commonest etiology.
Other associations include
- Marfan syndrome
- Loeys-Dietz syndrome
- Ehlers-Danlos syndrome
- Turner syndrome
- familial TAA syndrome
- Behcet disease
- deceleration injuries: have been reported to cause dilation of the segment just after the aortic arch (usually tends to represent pseudoaneurysms)
- infectious as well as non-infectious inflammatory conditions of the aorta or forms of aortitis such as
