It is important to be informed about the available procedures if you have a stroke or brain aneurysm. 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 includes information about the effectiveness of various aneurysm therapies.
Treatment of aneurysms with efficacy
Aneurysm treatment effectiveness can be assessed based on a variety of outcomes. The primary efficacy outcome is an mRS score of two or more, which is administered by an independent observer. The number of recurrences during the follow up period is another indicator of efficacy.
One study examined the occlusion rate of complex wide-neck bifurcation aeurysms. It showed that the majority of aneurysms were occlusive at six months after surgery. In addition, the angiographic appearance was either stable or improved. The results also showed that only a small percentage of aneurysms returned to the clinic during long-term surveillance.
Risk of rupture
Aneurysm treatment can cause rupture depending on the type. Aneurysms involving the vertebral, vertebrobasilar, and basilar vessels are at greater risk than those affecting the anterior circulation. Patients with aneurysms larger than 10mm in diameter are at greater risk.
There are also risk factors for alcohol and smoking. Aneurysm rupture could result from the damage that cigarettes can cause to the arteries. It is possible to also rupture if you have high blood pressure. Aneurysms that are larger tend to burst without symptoms. 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
Two main types of treatment for aneurysms include open surgery and Endovascular Coiling. Open surgery is more complicated, while endovascular coiling is minimally invasive. Both require the use of a catheter for passage through the blood vessels.
This procedure involves inserting a thin, flexible catheter into the neck of the aneurysm and advancing a coil that is shaped like a spring. The coil will seal the aneurysm's opening once it is in place. Sometimes multiple coils might be needed.
OHSU Brain Institute's expertise in treating brain aneurysms
The OHSU Brain Institute is well-versed in diagnosing and treating brain aneurysms. These are small, balloon-like mass that form in the arteries of your brain. They can cause subarachnoid hemorhage, which is a potentially life-threatening blood clot. 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 range in size from a few millimeters to the width of a quarter. Although they can be found anywhere in the brain or the base and skull of the skull, the majority are found along the arteries. Saccular aneurysms are attached to arteries by stems. They can be narrow or wide necked.
