How do aneurysms form?

Arteries are the life channels of the human body, constantly transporting the nutrients and blood needed by the body. If an artery ruptures or weakens, it can cause various diseases, such as aneurysms. Aneurysms can cause great harm to the human body. They can compress surrounding tissues and even break off and block small blood vessels. Especially if an aneurysm ruptures, it can cause sudden death in the patient. So how exactly do aneurysms form? How to take care of it?

Aneurysms can occur in arteries because of congenital defects in the middle muscle tissue, and inflammation can weaken the arterial wall.

An aneurysm is a permanent swelling that occurs due to a weakened artery wall. Aneurysms can form anywhere, but the most common and troublesome places for them to occur are in the arteries of the brain, the aorta, and the large arteries that carry blood from the heart to the rest of the body.

Causes of Aneurysm Formation

There are basically three reasons why an aneurysm occurs in an artery:

1. The arterial wall has three layers of tissue. The supporting strength of the artery is provided by the middle muscle layer, and this layer of tissue may have congenital defects.

Normal blood pressure in the affected artery causes a balloon-like enlargement called a saccular aneurysm. Aneurysms caused by congenital defects almost always occur in arteries at the base of the brain. They are called "berry" aneurysms because of their shape and because several aneurysms often form together.

2. No matter what the cause of the inflammation, it will weaken the arterial walls.

Most arterial inflammation is caused by diseases such as polyarteritis nodosa or bacterial endocarditis.

3. The muscular middle layer of some arterial walls slowly deteriorates due to chronic diseases such as atherosclerosis or hypertension.

Aneurysm Classification

1. An aneurysm caused by atherosclerosis is likely to be a sausage-shaped enlargement called a fusiform aneurysm, which develops along a small section of the artery.

2. Another similar swelling is caused by high blood pressure. Increased blood pressure in the arteries causes the artery walls to dilate in many different ways. It can even rupture the tissue layer of the arterial wall, forcing blood into the tissue layer. This disease is called a dissecting aneurysm.
