Aneurysm- Causes

Aneurysms may eventually rupture, cause fatal blood loss, or, in the case of a cerebral aneurysm, loss of consciousness.

In some cases, only the inner layer of the artery wall ruptures, which allows blood to track along the length of the artery and block any branching arteries

Aneurysms sometimes develop in the heart wall due to weakening of an area of heart muscle as a result of myocardial infarction

Aneurysms of the aorta may be detected by ultrasound scanning, and cerebral aneurysms by CT scanning or MRI.

Angiography provides information on all types of aneurysm. Ruptured or enlarged aneurysms require immediate surgery
