If you are suffering from a brain aneurysm, you should be aware of the procedures available. 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 and safety of various aneurysm procedures.
Efficacy of aneurysm treatment
Aneurysm therapies can be evaluated using a number of different outcomes. A mRS score greater than two is the primary outcome of efficacy. This score is determined by an independent observer. The number of recurrences occurred in the followup period is another measure of effectiveness.
One study evaluated the occlusion rate for complex wide-neck bifurcation aneurysms. The majority of aneurysms remained occlusive six months after surgery, according to the study. In addition, the angiographic appearance was stable or improved. However, it also showed that a small minority of aneurysms recurred during long-term follow-up.
Risque for rupture
The type of aneurysm treated will affect the likelihood of rupture. Aneurysms in vertebral and basilar arteries, the vertebrobasilar junction and the vertebral vein have greater risks than those in anterior circulation. Patients with aneurysms more than 10 millimeters in diameter are at higher risk.
Other risk factors include smoking and alcohol abuse. Aneurysm rupture could result from the damage that cigarettes can cause to the arteries. A rupture can also occur when there is high blood pressure. Aneurysms larger than normal tend to rupture quickly. Patients with aneurysms of the posterior communicating arterial artery are also more susceptible to rupture than those from other parts.
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 require the passage of a catheter through the blood vessels.
This involves inserting an extremely thin catheter into the neck area of the aneurysm, and then advancing a coil that looks similar to a spring. The coil will be able to seal off the aneurysm opening after it has been placed. In some cases, multiple coils may be required.
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 rupture and cause a life-threatening blood clot in the brain, known as subarachnoid hemorrhage. Fortunately, some of the country's most respected experts on brain aneurysms are located at the OHSU Brain Institute.
Aneurysms are weakened areas of the artery wall that can rupture at any time. They can vary in size, from a few millimeters up to a quarter. While they can develop anywhere in the brain, the majority occur along arteries connecting the brain and the base of the skull. One type of aneurysm called a saccular one is connected to an artery through a stem. It can have a short neck or a long neck.
