You should know the options available to you if you have a 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 covers the Efficacy of various aneurysm treatments.
Treatment of aneurysms is effective
There are many ways to evaluate the effectiveness of aneurysm treatments, including complete or close-to-complete occlusion. An independent observer determines the primary efficacy outcome. It is a mRS score of at least two. The number of recurrences occurred in the followup period is another measure of effectiveness.
One study looked at the occlusion rates for complex wide neck bifurcation aneurysms. It showed that the majority aneurysms became occlusive six-months after surgery. A stable or improved angiographic appearance was also found. The study also showed that an estimated 1% of aneurysms would recur in long-term followup.
Risk of rupturing
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.
There are also risk factors for alcohol and smoking. The damage cigarette smoke does to the arteries can lead to aneurysm rupture. It is possible to also rupture if you have high blood pressure. Larger aneurysms can rupture without warning. Patients with aneurysms in the posterior communicating artery are more likely to experience rupture than patients from any other part.
Treatments for aneurysms
Procedures to treat aneurysms can be categorized into two main types: open surgery and endovascular coiling. Endovascular coiling, on the other hand, is less invasive and more complex. Both require the passage of a catheter through the blood vessels.
The procedure involves inserting a thin flexible catheter into the neck to create an aneurysm. Next, a coil is advanced that looks like a spring. The coil will seal the aneurysm's opening once it is in place. Sometimes multiple coils are necessary.
The expertise of the OHSU Brain Institute in treating brain aneurysms
The OHSU Brain Institute has extensive expertise in the diagnosis and treatment of brain aneurysms, which are balloon-like masses that develop in the arteries of the brain. Subarachnoid bleeding is when the blood clots in the brain can rupture. Fortunately, some of the country's most respected experts on brain aneurysms are located at the OHSU Brain Institute.
Aneurysms occur when the artery walls are weak and they can burst at any time. Aneurysms may be anywhere from a few micrometers to the size of a quarter. While they can develop anywhere in the brain, the majority occur along arteries connecting the brain and the base of the skull. A saccular type, also known as an aneurysm (or saccular), is an aneurysm attached to an arterial by a stem. This can have either a narrow neck or one with a wide neck.
