Treatment for an aneurysm depends on its size and location. If the aneurysm is small(less than 5 cm [2 in] in diameter) and you have no symptoms, your physician may advise a "watch-and-wait" approach with regularly scheduled examinations and imaging studies. Quitting smoking and controlling high blood pressure are essential. Medications to lower high cholesterol coupled with programs that help you exercise, quit smoking, and follow a heart-healthy diet can also be helpful. However, if your aneurysm is larger or if the aneurysm is growing more than 1 cm (0.4 in) per year, surgery may be the best treatment option.
