Body was changed:

An aortic arch aneurysm is a less common form of thoracic aortic aneurysm and may account for around 10% of such aneurysms.

Epidemiology

There is a recognised male predilection with most patient's presenting around to 6th to 7th decades of life.

Clinical presentation

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.

Pathology

As with other thoracic aneurysms, atherosclerosis still remains commonest aetiology.
