It is important to be informed about the available procedures if you have a stroke or brain aneurysm. This article explains the risks and benefits of treatment and will provide you with information about the OHSU Brain Institute's expertise in treating brain aneurysms. It also covers the efficacy and safety of various aneurysm procedures.
Aneurysm treatment is highly effective
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 evaluated the rate of occlusion in complex wide-neck bifurcation andeurysms. It was found that most aneurysms had become occlusive by six months. A stable or improved angiographic appearance was also found. However, it showed that only a few aneurysms did recur after long-term monitoring.
Risk of rupture
The type of aneurysm and the severity of rupture are dependent on its treatment. Aneurysms in the vertebral artery, vertebrobasilar junction, and basilar artery have higher risks than those in the anterior circulation. Patients with aneurysms larger than 10mm in diameter are at greater risk.
Another risk factor is smoking and drinking. Aneurysm rupture may result from the damage that smoking can do to your arteries. High blood pressure can also lead to rupture. 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.
Procedures to treat aneurysms
Procedures to treat aneurysms can be categorized into two main types: open surgery and endovascular coiling. Endovascular coiling is less invasive than open surgery. Both involve the use of a catheter to travel through the blood vessel system.
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. Sometimes, multiple coils are required.
The expertise of the OHSU Brain Institute when it comes to treating brain aneurysms
The OHSU Brain Institute specializes on the diagnosis and treatment for brain aneurysms. They are balloon-like growths in the arteries that lead to damage to 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 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. While they can develop anywhere in the brain, the majority occur along arteries connecting the brain and the base of the skull. 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.
