A brain aneurysm rarely causes any symptoms unless it bursts (ruptures). If the tear occurs on the innermost layer of the arterial wall, blood channels into and weakens the wall, increasing the risk of rupture. Risk factors for developing an aneurysm include a family history of aneurysm, HBP, high cholesterol, and smoking. The decision to operate on an unruptured aneurysm in the aorta depends on a number of factors related to the individual patient and features of the aneurysm.
