Surgery
When 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
.
Surgery for ischemic stroke
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?
If a stroke has occurred because of a narrowed carotid
artery, a carotid endarterectomy may help lower the risk of a future
stroke.
You are most likely to benefit from surgery if you have
had a TIA or mild stroke in the past 6 months and have 70% or greater narrowing
in one of your carotid arteries. Carotid endarterectomy may be appropriate if
your carotid arteries are moderately or severely blocked (50% to 69% narrowing)
and you have had one or more TIAs or mild strokes.13 Talk to your doctor about whether a carotid
endarterectomy is right for you.
Carotid endarterectomies are
most successful when they are performed by a surgeon who is experienced in the
procedure. Ask your doctor about his or her rate of complications.
Surgery for hemorrhagic stroke
Surgeries for hemorrhagic stroke include:
- 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.
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.14 In cases where endovascular coil
embolization is not possible, aneurysm clipping with craniotomy is done.
