Aneurysms
Aneurysms
Aneurysms (pronounced: /æn.jʊˈrɪz.əm/) are abnormal bulges or "ballooning" in the wall of a blood vessel. They can occur in any blood vessel, with particularly lethal examples including aneurysms in the brain and aorta.
Etymology
The term "aneurysm" comes from the Greek word "aneurysma," which means "dilation." This is derived from the Greek word "aneurynein" which means "to dilate."
Types of Aneurysms
There are several types of aneurysms, including:
- Thoracic Aortic Aneurysm: This type of aneurysm occurs in the part of the aorta running through the chest.
- Abdominal Aortic Aneurysm: This type of aneurysm occurs in the part of the aorta running through the abdomen.
- Cerebral Aneurysm: Also known as a brain aneurysm, this type occurs in the brain.
Symptoms
Symptoms of aneurysms can vary depending on their location and size. Some aneurysms may not show symptoms until they rupture. Symptoms of a ruptured aneurysm can include sudden, severe pain, nausea, vomiting, and loss of consciousness.
Causes
Aneurysms can be caused by a variety of factors, including high blood pressure, high cholesterol, smoking, and genetic factors. Certain diseases, such as Marfan Syndrome and Ehlers-Danlos Syndrome, can also increase the risk of developing an aneurysm.
Treatment
Treatment for aneurysms can include medication to lower blood pressure and reduce the risk of rupture, and surgery to repair the aneurysm. The type of treatment depends on the size and location of the aneurysm, as well as the patient's overall health.
