If you are suffering from a brain aneurysm, you should be aware of the procedures available. This article will explain the risks and benefits of treatment as well as provide information about the OHSU Brain Institute's expertise treating brain aneurysms. It also covers the efficacy and safety of various aneurysm procedures.
Aneurysm treatment is highly effective
Aneurysm treatments are evaluated on several outcomes. These include complete or near-complete obstruction. The primary efficacy outcome is an mRS score of two or more, which is administered by an independent observer. Efficacy is also assessed by the number of recurrences that occurred during the follow-up period.
One study looked at the occlusion rates for complex wide neck bifurcation aneurysms. It showed that the majority of aneurysms were occlusive at six months after surgery. In addition, the angiographic appearance was either stable or improved. However, it showed that only a few aneurysms did recur after long-term monitoring.
Risque of rupture
The risk of rupture after aneurysm treatments varies depending on the type of aneurysm. Aneurysms that occur in the vertebral arterial, vertebrobasilar joint, and basilar vein are more likely to rupture than those that occur in the anterior circulation. Aneurysms with a diameter greater than 10 mm are more at risk.
Another risk factor is smoking and drinking. Aneurysm rupture can result from the damage caused by cigarette smoke to the arteries. Rissure can also be caused by high blood pressure. Larger aneurysms can rupture without warning. Patients with aneurysms that are posteriorly communicating artery aneurysms have a higher risk of rupture than patients who have them in any other area.
Treatments for aneurysms
Procedures to treat aneurysms can be categorized into two main types: open surgery and endovascular coiling. Endovascular coiling is less invasive than open surgery. Both require the passage of a catheter through the blood vessels.
The procedure involves inserting thin, flexible catheter in the neck of the theeurysm. After that, a coil shaped like a Spring is advanced. Once the coil is in position, it will seal off any openings. Sometimes multiple coils might be needed.
The expertise of OHSU Brain Institute for treating brain Aneurysms
The OHSU Brain Institute specializes on the diagnosis and treatment for brain aneurysms. They are balloon-like growths in the arteries that lead to damage to the brain. Subarachnoid bleeding is when the blood clots in the brain can rupture. Fortunately, the OHSU Brain Institute houses some of the most respected brain aneurysm experts in the country.
Aneurysms occur when the artery walls are weak and they can burst at any time. They can be as small or large as one quarter of an inch. While they can develop anywhere in the brain, the majority occur along arteries connecting the brain and the base of the skull. Saccular aneurysms are attached to arteries by stems. They can be narrow or wide necked.
