It is important to be informed about the available procedures if you have a stroke or brain aneurysm. This article will discuss the benefits and risks of treatment, as well as information about the OHSU Brain Institute’s expertise in treating brain aneurisms. It also covers the Efficacy of various aneurysm treatments.
Treatment for aneurysms has high 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 and frequency of recurrences over the follow-up period also determines efficacy.
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. The angiographic appearance of the aneurysms was also stable or improved. The results also showed that only a small percentage of aneurysms returned to the clinic during long-term surveillance.
Risk of rupturing
Aneurysm treatment can cause rupture depending on the type. Aneurysms located in the basilar artery, vertebrobasilar intersection, and vertebral artery pose higher risks than those found in the anterior circulation. Patients with aneurysms larger than 10mm in diameter are at greater risk.
There are also risk factors for alcohol and smoking. The damage cigarette smoke does to the arteries can lead to aneurysm rupture. High blood pressure can also lead to rupture. Larger aneurysms are more likely to rupture without any 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.
Aneurysm treatment procedures
There are two types of aneurysm treatment: endovascular coiling and open surgery. Open surgery is more invasive, while endovascular coiling is a minimally invasive procedure. Both procedures require the use a catheter to pass through the blood vessel system.
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. Multiple coils may be necessary in some cases.
The expertise of the OHSU Brain Institute when it comes to treating brain aneurysms
The OHSU Brain Institute specializes in the diagnosis and treatment brain aneurysms. These balloon-like masses form in the arteries in 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 result in weakening of the artery wall, which can rupture at anytime. They can vary in size, from a few millimeters up to a quarter. They can form anywhere in the brain. However, most occur near the arteries that connect the brain to the base of skull. One type of aneurysm, called a saccular aneurysm, is attached to an artery by a stem and can have a narrow neck or a wide one.
