What are the symptoms that an aneurysm has ruptured?
Aneurysms often go undetected because they can have no symptoms until they
rupture and bleed. When that happens, it can cause a sudden severe headache and sometimes nothing more than that, Kirshner
says. "But it is usually not like any other headache you've had. It is very
sudden or severe, the worst headache of your life." Other symptoms include
pain, dizziness, nausea, and sensitivity to light.
One-third to nearly half of patients have minor hemorrhages or "warning
leaks" that later lead to a severe devastating brain hemorrhage days
Sometimes, when an aneurysm ruptures, it can go unnoticed, with the person
passing off the headache. But once it ruptures, Kirshner says, it is more
likely to re-bleed.
Is there a typical age bracket for aneurysms to rupture?
"They are most common in middle age -- the 40s and 50s are the peak
ages," he says. But they can happen at any age. "I've seen them in
teenagers. They do occasionally occur in elderly people."
What can someone do to reduce the risk of an aneurysm growing and rupturing?
"Not smoking and treating hypertension prevent aneurysms from growing and
rupturing," Kirshner says.
In general, what is the outlook for someone whose brain aneurysm bursts?
The prognosis, Kirshner says, "is very uncertain." A ruptured
aneurysm can cause sudden death, he says. In general, "if you are in bad
shape right in the beginning, the odds of recovery are much lower." The
overall death rate once the aneurysm ruptures is about 40%, he says.
What might be done when the rupture is discovered?
Getting treatment as soon as possible is critical, he says. If it's possible
to do surgery, one option is to go in surgically and put a clip across the
aneurysm to stop bleeding. "An even more common surgery is to go through
the artery and deploy a coil [into the aneurysm, using a tiny catheter] and the
coil causes the aneurysm to shut off." The coil causes a clot to form
around the sac, sealing off the aneurysm defect.
