Read about aneurysm medical facts: what is the definition of aneurysm, medical treatment & how to treat aneurysm, risk factors, and related aneurysm diseases.

Definition: What is "Aneurysm"?


An aneurysm is a localized, balloon-like, blood-filled dilation of any blood vessel, which is caused by a disease or weakening of the vessel wall. An aneurysm usually occurs in arteries located in the brain & in the aorta (heart). The bulge in blood vessels could burst, which could lead to death any time. However, the larger aneurysm becomes, the larger chances it is to burst.

Treatment: How to Treat "Aneurysm"?

The treatments for arterial aneurysms are watchful waiting & control of blood pressure as well as surgical intervention. Recently, new invasive techniques, such as endovascular, is used in treating aneurysms. Brain aneurysms have two treatment options - endovascular coiling & surgical clipping. For aortic (heart) aneurysms that occur in vessels that supply blood to the head, arms & legs, surgery involves a replacement of the weakened section of the vessel with a graft or an artificial tube. Recently, metallic-covered stent grafts are inserted through the arteries & deployed through the aneurysm.

Risk Factors

The risks of aneurysms include blood clotting & rupture. Rupture leads to decrease in blood pressure, lightheadedness & increase in heart rate. The risk of death is high for patients with aneurysms, except for ruptures in the extremities. Risk factors of aneurysm are obesity, diabetes, alcoholism, tobacco smoking, copper deficiency & hypertension. Aneurysms are caused by copper deficiency.
