The available options should be known if you suffer from a cerebral 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 includes information about the effectiveness of various aneurysm therapies.
Treatment for aneurysms has high efficacy
Aneurysm treatments are evaluated on several outcomes. These include complete or near-complete obstruction. An independent observer determines the primary efficacy outcome. It is a mRS score of at least two. 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. In addition, the angiographic appearance was either stable or improved. The study also showed that an estimated 1% of aneurysms would recur in long-term followup.
Risk of rupture
The risk of rupture after aneurysm treatments varies depending on the type of aneurysm. Aneurysms involving the vertebral, vertebrobasilar, and basilar vessels are at greater risk than those affecting the anterior circulation. Patients with aneurysms more than 10 millimeters in diameter are at higher risk.
There are also risk factors for alcohol and smoking. Aneurysm rupture can result from the damage caused by cigarette smoke to the arteries. It is possible to also rupture if you have high blood pressure. Aneurysms larger than normal tend to rupture quickly. Patients with posterior communicating artery aneurysms are also more likely to rupture than those in any other part of the body.
Aneurysm treatment techniques
The two main types of procedures to treat aneurysms are open surgery and endovascular coiling. Endovascular coiling is less invasive than open surgery. Both procedures require the use a catheter to pass through the blood vessel system.
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. Once the coil is in place, it will help seal off the opening of the aneurysm. Sometimes, multiple coils are required.
The expertise of the OHSU Brain Institute when it comes to 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. They can rupture and cause life-threatening hemorhage in the brain. 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. 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. A saccular aneurysm is a type of aneurysm that attaches to an artery via a stem. It can either have a narrow neck, or a wider neck.
