Aneurysms can also cause problems through mass effect, that is by compressing other important nearby structures. Rupture of an aneurysm is the most feared aneurysm complication. For this reason, the major focus of aneurysm treatment is to obliterate the aneurysm before it has a chance to burst. When this is not possible, occlusion of the aneurysm is usually performed as soon as possible after the initial hemorrhage in order to prevent a recurrence. The two major methods of aneurysm treatment are microsurgery and endovascular surgery.
Microsurgery is the more well established and frequently used method.
Microsurgical treatment for aneurysms involves a surgical procedure to expose the aneurysm by slipping under and around the brain using delicate instruments and high powered magnification. The clip stops blood from entering the aneurysm, thereby preventing it from bleeding. Microsurgical techniques have been around for many years and are constantly advancing. Endovascular Aneurysm Surgery Endovascular surgery for aneurysms has come out of the relatively new field of interventional neuroradiology. Once found, the aneurysm is then filled from the inside with tiny platinum coils.
