It is important to be informed about the available procedures if you have a stroke or brain aneurysm. This article will help you understand the risks and the benefits of treatment. It also provides information about the OHSU Brain Institute, which specializes in treating brain aneurysms. 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. An independent observer determines the primary efficacy outcome. It is a mRS score of at least two. The number of recurrences during the follow up period is another indicator of 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. A stable or improved angiographic appearance was also found. However, it also showed that a small minority of aneurysms recurred during long-term follow-up.
Risque for rupture
The risk of rupture after aneurysm treatments varies depending on the type of aneurysm. Aneurysms in vertebral and basilar arteries, the vertebrobasilar junction and the vertebral vein have greater risks than those in anterior circulation. Patients with aneurysms that are more than 10 mm in diameter are at higher risk.
Other risk factors include smoking and alcohol abuse. Aneurysm rupture can result from the damage caused by cigarette smoke to the arteries. A rupture can also occur when there is high blood pressure. Larger aneurysms tend to rupture without any symptoms. Patients with aneurysms in the posterior communicating artery are more likely to experience rupture than patients from any other part.
Aneurysm treatment techniques
The two main types of procedures to treat aneurysms are open surgery and endovascular coiling. Endovascular coiling is a less invasive procedure, while open surgery is more involved. Both involve the use of a catheter to travel through the blood vessel system.
This procedure involves inserting the catheter through the neck of aneurysm. Then, the coil will be shaped like springs. Once the coil is in position, it will seal off any openings. Sometimes multiple coils are necessary.
Expertise of the OHSU Brain Institute on treating brain aneurysms
The OHSU Brain Institute has extensive experience in diagnosing and treating brain aneurisms. These are balloon-like tumors that can form in the arteries. They can cause subarachnoid hemorhage, which is a potentially life-threatening blood clot. 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 occur anywhere in the skull, most of them are found along the arteries connecting the brain to the base. 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.
