Aneurysms

Unruptured aneurysms

An aneurysm is a bulge or weakening of the artery wall. Physicians use a minimally invasive procedure called “coiling” to block the blood flow through the aneurysm to prevent it from rupturing (bleeding). A ruptured aneurysm may lead to a life-threatening stroke or death. The purpose of treating an unruptured aneurysm is to prevent the bleeding in the first place. From January 1, 2011 through October 1, 2013, Novant Health Forsyth Medical Center reported just two complications, only one of which resulted in moderate disability.

Ruptured aneurysms

A ruptured aneurysm is when the artery wall bursts and leads to bleeding in the brain. The diagnosis of a ruptured aneurysm is serious. Many patients die or suffer disability. Recovery from a ruptured aneurysm depends not only on fixing the aneurysm, but also treatment of the patient for the initial bleeding in the brain. Recovery also depends on the initial condition of the patient on arrival to the Emergency Room. From January 1, 2011 through October 1, 2013, 67 percent of patients had no, or minor, disability one month after the bleeding from the aneurysm was treated, despite some who arrived at the hospital with severe impairment.

Clinical Outcomes of Ruptured
Aneurysms by 30 day Modified Rankin Scale

The Modified Rankin Scale (MRS) is an internationally accepted measure of disability related to stroke. A score of 0 is normal, 1-2 represents minor disability, 3-5 represents moderate to severe disability, and 6 is death. Of the patients treated with coiling for a ruptured aneurysm, two-thirds had no, or minor, disability 30 days after rupture of the aneurysm. Most of the patients who suffered death or major disability were in poor neurologic condition on arrival to the hospital.
