Caused by weakness in the arterial wall, an aneurysm is the enlargement of an artery which causes distension or creates a bulge. The condition often doesn't present any symptoms, however, a ruptured aneurysm can cause internal bleeding, which could result in a fatality.
There are various types of aneurysms and they are classified by their position within the body. An aneurysm can happen in any part of the body, such as the legs, the spleen, and the aorta. However, the arteries of the heart and brain are the most common sites in which serious aneurysms occur.
The bulge can take two main forms:
1. Fusiform aneurysms: in this form, the bulge reaches all sides of a blood vessel.
2. Saccular aneurysms: in this form, the bulge only reaches one side.
The risk of an aneurysm rupture is dependent on the size of the bulge.
