Your doctor will think about several things before deciding the best treatment for you. Things that will determine the type of treatment you receive include your age, size and location of the aneurysm, any additional risk factors, and your overall health.
If you have an aneurysm with a low risk of rupture, you and your doctor may want to continue to observe your condition rather than do surgery. You might make this choice because surgery also has risks. Your doctor may suggest ways to keep your blood vessels as healthy as possible, such as managing high blood pressure and not smoking. If your aneurysm is large or causing pain or other symptoms, though, or if you have had a previous ruptured aneurysm, your doctor may recommend surgery.
The following procedures are used to treat both ruptured and unruptured brain aneurysms:
During this procedure, a small tube is inserted into the affected artery and positioned near the aneurysm. For coil embolization, soft metal coils are then moved through the tube into the aneurysm, filling the aneurysm and making it less likely to rupture. In mesh embolization, mesh is placed in the aneurysm, reducing blood flow to the aneurysm and making it less likely to rupture. These procedures are less invasive than surgery. But they involve risks, including rupture of the aneurysm.
This surgery involves placing a small metal clip around the base of the aneurysm to isolate it from normal blood circulation. This decreases the pressure on the aneurysm and prevents it from rupturing. Whether this surgery can be done depends on the location of the aneurysm, its size, and your general health.
Both of these procedures should be done in a hospital where many procedures like these are done.
Some aneurysms bulge in such a way that the aneurysm has to be cut out and the ends of the blood vessel stitched together, but this is very rare. Sometimes the artery is not long enough to stitch together, and a piece of another artery has to be used.
Aneurysms that have bled are very serious. In many cases, they lead to death or disability. Management includes hospitalization, intensive care to relieve pressure in the brain and maintain breathing and vital functions (such as blood pressure), and treatment to prevent rebleeding.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
