Cerebral Aneurysm

A cerebral aneurysm is an outpouching of a blood vessel in the brain which occurs due to weakness of the blood vessel wall. There are a number of factors that contribute to aneurysm formation including high blood pressure, smoking, genetics (family history), and connective tissue disorders. Sometimes no cause for aneurysm formation is identified. Aneurysms are dangerous because they can rupture, which results in bleeding around the brain, a condition called subarachnoid hemorrhage. Subarachnoid hemorrhage may result in stroke, coma, paralysis and possibly death. Many times aneurysms are found before they rupture because they are seen incidentally on imaging studies such as CTs or MRIs or because the aneurysm is causing symptoms. Aneurysms can be treated endovascularly, meaning minimally invasively through the wrist or the leg, with the use of devices such as coils, stents and intrasaccular flow disruptors. Aneurysms may also be treated with surgical clipping, in which the skull is opened, the aneurysm is dissected away from the brain and a clip is placed across the aneurysm.

Am I a candidate for Cerebral Aneurysm Treatment?

All patients with cerebral aneurysms should be evaluated by a neurointerventionalist. The decision of whether to treat an aneurysm and the method in which to treat it depends on many factors including patient’s age, medical conditions, aneurysm size, shape and location.

What can I expect from an Aneurysm Treatment?

At MRA, we offer minimally invasive solutions to treat intracranial aneurysms. The procedure is performed through the wrist or leg without the need to make an incision. Using the arteries of the arms and legs as a highway, we are able to access the blood vessels of the brain including the aneurysm. Depending on the size and location of the aneurysm, a stent may be placed across the aneurysm to seal it off or devices such as coils may be placed inside the aneurysm to cure it. The ultimate goal of the procedure is to prevent any blood flow into the aneurysm so that it can never rupture. Patients are asleep for the procedure and usually spend 1 night in the hospital.  Recovery is short and most patients go home the following day and return to their normal activities within a few days. You may be sore at the site of the procedure in the wrist or leg, but there are no stitches or incisions.
