What is an aneurysm?

An aneurysm is an abnormal bulging or ballooning of a blood vessel. It occurs when the pressure inside the blood vessel causes the weakened area of the vessel wall to widen or swell. Aneurysms can occur in any blood vessel in the body, but the most common types are found in the brain (cerebral aneurysm) and the aorta (aortic aneurysm).

What causes an aneurysm?

The exact causes of an aneurysm are not always clear, but several factors can contribute to their development. These include high blood pressure, atherosclerosis (hardening of the arteries), trauma to the blood vessels, certain infections, genetic factors, and tobacco use. Additionally, some aneurysms may be present at birth (congenital aneurysms).

What types of aneurysm are there?

There are several types of aneurysms, including:

  1. Cerebral Aneurysm: These occur in the blood vessels of the brain.
  2. Aortic Aneurysm: These develop in the aorta, the largest blood vessel that carries blood from the heart to the rest of the body.
  3. Peripheral Aneurysm: These occur in blood vessels outside the brain and aorta, such as in the legs or abdomen.

What symptoms does an aneurysm cause?

The symptoms of an aneurysm depend on its size, location, and whether it has ruptured or not. Small aneurysms may not cause any symptoms and are often discovered incidentally during medical tests. However, larger or ruptured aneurysms can lead to symptoms such as severe headache, blurred vision, dizziness, nausea, neck pain, difficulty speaking, limb weakness, or loss of consciousness. In some cases, aneurysms may not cause symptoms until they rupture, which can be life-threatening.

How is an aneurysm diagnosed?

The diagnosis of an aneurysm typically involves a combination of imaging tests. These may include:

  1. Computed Tomography (CT) Scan: This provides detailed images of the brain, abdomen, or chest, allowing doctors to identify aneurysms.
  2. **M

Internal bleeding that could be life-threatening could happen if an aneurysm bursts.

An aneurysm is a localized bulge in the arterial blood vessels, usually found in the main artery (aorta), cerebral arteries, or leg arteries. It results from vascular calcification (arteriosclerosis), which causes a weakness in the medial layer of the artery wall. An ultrasound examination or computer tomography are both used to make the diagnosis. Treatment depends on the size, diameter, and location of the aneurysm.

What causes an aneurysm?

An aneurysm can develop when a disease or injury weakens the arterial wall. Wall damage of this kind frequently results from arteriosclerosis, also known as “hardening of the arteries” in everyday language. A calcification of an arterial vessel, such as the leg arteries in peripheral arterial occlusive disease (PAD) or the coronary arteries in coronary heart disease (CHD), also denotes a calcification of other arteries. As a result, pre-existing arteriosclerosis-related illnesses (like CHD) are also taken into account as risk factors for aneurysms.

Other risk factors for abdominal aortic aneurysms include advanced age, male gender, smoking, high blood pressure, and a favorable family history. You are more likely to develop an abdominal aortic aneurysm if it affects your family members frequently.

Congenital blood vessel malformations, connective tissue diseases (such as Marfan syndrome or Ehlers-Danlos syndrome), wounds to the vessel wall, and, less frequently, bacterial infections like syphilis or tuberculosis can also cause aneurysms. Kawasaki syndrome is characterized by smaller aneurysms on the coronary arteries. A previous heart attack is the main factor in the development of a heart wall aneurysm.

Which symptoms are brought on by an aneurysm?

Typically, an aneurysm has no symptoms. They frequently come to light by accident during a routine exam, such as an abdominal ultrasound or a chest x-ray. However, regular examinations should be performed as soon as they are found in order to catch an increase in aneurysm size early. The likelihood that an aneurysm will burst and cause potentially fatal bleeding increases with its size. The size (diameter) and rate of growth per year are used to determine the need for surgery.

An aneurysm can cause symptoms such as difficulty swallowing, coughing, hoarseness, breathing difficulties, ECG changes, abdominal or back pain, and bleeding from an aneurysm in the cerebral arteries. Blood clots can form in aneurysms, leading to vascular occlusions.

How is an aneurysm treated?

An aneurysm rupture can have life-threatening consequences, so it must be treated immediately with a surgical intervention. Risk factors such as high blood pressure and dyslipidemia should be treated, and anyone who smokes should try to give up their vice.

When is surgery required?

Doctors recommend that an aneurysm of a certain size be removed by surgery. For an abdominal aortic aneurysm of four to five centimeters in diameter, the risk of it rupturing is about one percent per year. From a size of five centimeters, the risk increases to more than ten to 20 percent per year. Women are more at risk of tearing, so they should be treated when they are 4.5 to 5 centimeters in size. 

An increase in size of more than 10 millimeters per year can also lead to an operation recommendation. If the aneurysm affects the ascending section of the aorta (aorta ascendens) or the aortic arch, surgical treatment is usually carried out. In the case of an aneurysm in the descending section of the aorta (aorta descendens), endoluminal prostheses are increasingly being used (TEVAR). The timing of the operation must always be determined individually based on personal risk factors.
