An aneurysm that divides the three layers of the artery wall, as opposed to inflating out the entire wall, is known as a dissecting aneurysm.
<h3>
What causes an aneurysm to form?</h3>
Multiple circumstances that lead to the breakdown of the well-organized structural elements (proteins) of the aortic wall, which maintain and stabilize the wall, can result in an aneurysm. Uncertainty surrounds the precise cause. Aneurysmal disease is thought to be significantly influenced by atherosclerosis, which is the hardening of the arteries with plaque.
Surgical intervention can be required since an aneurysm may continue to grow in size and the arterial wall may deteriorate over time. One of the objectives of therapy is to prevent aneurysm rupture. The risk of an aneurysm rupturing increases with its size (bursting). A rupture could lead to fatal hemorrhage (uncontrolled bleeding), which is life-threatening.
