StrokeSurgeryWhen surgery is being considered after a
stroke, your age, prior overall health, and current
condition are major factors in the decision. Surgery is not recommended as part
of the initial or emergency treatment for
ischemic
stroke .1 Your doctor may perform: - Carotid endarterectomy. Carotid endarterectomy is
surgery to remove
plaque buildup in the
carotid arteries in people with moderate to severe
narrowing of the carotid arteries. This surgery can help prevent additional
strokes. For more information, see:
Should I have carotid
endarterectomy?
- Surgery to drain or remove blood in or around the brain that was
caused by a bleeding blood vessel (hemorrhagic stroke).
- A
procedure (endovascular coil embolization) to
repair a brain
aneurysm that is the cause of a hemorrhagic stroke. A
small coil is inserted into the aneurysm to block it off. Whether this surgery
can be done depends on the location of the aneurysm, its size, and whether you
are healthy enough to withstand the procedure.
- Surgery to remove or
block off abnormally formed blood vessels (arteriovenous malformations) that
have caused bleeding in the brain. An arteriovenous malformation is a
congenital disorder, which means it was present at birth. An arteriovenous
malformation causes an abnormal web of blood vessels and veins in the brain,
brain stem, or spinal cord. The vessel walls of an arteriovenous malformation
may become weak and leak or rupture.
If a stroke has occurred because of a narrowed carotid artery, a
carotid endarterectomy may help lower the risk of a future stroke. Carotid endarterectomies are most successful when they are
performed by a surgeon who is experienced in the procedure and in a hospital
that is well equipped to take care of any complications that may occur during
or after the procedure. Ask your doctor about his or her rate of complications
and the complication rate at the hospital where the surgery will be
done. Carotid endarterectomy is not
recommended: - As an emergency treatment for people who have
had a stroke caused by a clot (ischemic stroke
). - For
people who are not expected to survive after their stroke.
- When the
risks of surgery outweigh the benefits. A person may have medical problems that
make surgery too risky, or a skilled surgeon may not be
available.
- For people who have a
transient ischemic attack (TIA) or stroke involving
arteries in the back of the brain (vertebrobasilar arteries).
- For
people who have minimal hardening and narrowing of the carotid arteries (less
than 50% narrowing), even if they have had a transient ischemic attack (TIA).
For these people, the surgical risks outweigh the benefits.
- For people with moderate hardening
and narrowing of the carotid arteries (50% to 69% narrowing). The benefit of
surgery for these people is still under investigation.
People with a
brain aneurysm need evaluation of all their symptoms
to determine whether and when surgery is needed. Endovascular coil embolization
is the preferred treatment for people with a brain aneurysm. It is also used
for those who are at high risk for complications from a surgical repair of the
aneurysm.16 In cases where endovascular coil
embolization is not possible, aneurysm clipping with craniotomy is done.
