Aneurysm
An aneurysm is a thin-walled blister on a blood vessel inside the head. These develop over time and are most common in people with high blood pressure. They rarely run in families. Aneurysms have a tendency to rupture and bleed, with potentially catastrophic results. In those people who survive such an episode, surgery is often employed to repair these weak areas. In some instances, aneurysms are discovered on a CT scan or MRI scan, and can be treated surgically before they rupture, thereby markedly reducing the risk to the person harboring the aneurysm.
Aneurysm surgery is technically challenging. Using a team approach with neuroradiologists, the surgeons of New England Neurological Associates use advanced imaging techniques, such as Spiral CT, to produce three-dimensional computer generated images of the aneurysm and its surrounding vessels. At the time of surgery, an arteriogram is performed in the operating room. This confirms succesful treatment and allows immediate correction of any potential problem, thereby improving outcomes and patient safety. These advanced methods are not widely available throughout the country at this time, but they are highly desirable and allow safer treatment of complex aneurysms.
