Carotid artery hemorrhage.
It is caused when a portion of the artery wall weakens. Like a balloon, as the aneurysm expands, the artery wall grows progressively thinner, increasing the likelihood that the aneurysm will burst.
Rupture of the carotid arteries, which provide blood supply to the head and neck, results in massive haemorrhage leading to death within a matter of minutes in 33% of cases.
