Types of Aneurysm
The type of aneurysm depends on the location where the ballooning happened. Generally, we have 3 types, namely abdominal, cerebral, and thoracic.
In an abdominal aortic aneurysm, the aorta or the big blood vessel that brings blood to the legs, pelvis, and abdomen is affected. Like mentioned earlier, the aorta weakens and bulges outward.
Although it can happen to anyone, it’s most common among men over the age of 60 who have at least one risk factor. These risk factors include smoking, obesity, high cholesterol, hypertension, family history of aneurysm, and emphysema.
Please note that a ruptured aneurysm, regardless of type, is a dangerous occurrence. In most cases, the condition is asymptomatic, but when the signs show up, they may resemble a heart attack. The patient may exhibit:
To continue with the discussion about the aneurysm types and causes, let’s talk about the thoracic aneurysm.
In the thoracic aneurysm, the affected part is the aorta that passes through the chest. Like the abdominal aortic aneurysm, the thoracic aneurysm is also often asymptomatic. However, patients may experience:
- Back pain
- Hoarseness of voice
- Shortness of breath
Before the rupture of the aneurysm, the patient may also encounter chest pain.
One interesting thing to note about thoracic aortic aneurysm is that some reports say that syphilis is one risk factor.
A cerebral aneurysm happens when the blood vessel in the brain is affected; hence, it’s also called intracranial or brain aneurysm. Alarmingly, reports say this type of aneurysm affects about 5% of the population.
You can subdivide this into several types, but the most common is called “berry aneurysm.” The size of the bulge in the berry aneurysm may range from a few millimeters to more than 1 centimeter.
