After receiving emergency care, some stroke
patients may be helped by surgery.
For Strokes from Blockage
Most strokes occur when a blood vessel in the
brain is blocked and blood flow stops. This
type of stroke is called an ischemic (iss-KEYmik) stroke. The blockage may be caused by
a blood clot, and severe brain swelling may
result. Life-saving surgery may be necessary
to remove the clot and the brain tissue that
has died from lack of oxygen.
A blockage also can occur when the artery
itself narrows. A harmful fatty deposit, called
plaque (PLAK), may build up in an artery
and then block it. Sometimes clots form,
which can then break off and travel to block
another artery in the brain. Some patients can
be helped by a procedure called angioplasty
(AN-jee-oh-plass-tee). During the procedure,
a tiny balloon at the end of a long, thin tube
is pushed through the artery to the blockage.
When the balloon is inflated, it opens the
artery. In addition, a mesh tube may be placed
inside the artery to help hold it open. The
tube is called a stent. The procedure usually
requires a hospital stay of several days.
For Blockage in the Neck
The main arteries in the neck help supply the
brain with blood. They are called the carotid
(kuh-RAW-tid) arteries. When patients have
a serious blockage in these arteries, surgery
may be done to prevent a stroke or a ministroke, which is also called a TIA. The operation is called a carotid endarterectomy
(en-dar-ter-EK-tuh-mee).
This procedure cleans out and opens up the
narrowed artery. During the operation, the
surgeon scrapes away plaque from the wall of
the artery. Blood can then flow freely through
the artery to the brain. A patient usually stays
in the hospital 2 to 3 days for this operation.
For Strokes from Altered Blood Flow
Blood flow to the brain may decrease temporarily in some patients. This is called a ministroke or a TIA, which stands for transient
(TRANS-yent) ischemic (iss-KEY-mik) attack.
While the brain is not getting enough blood,
it cannot work properly. Patients who have
TIAs get symptoms for a short time that make
it difficult for them to function.
Bypass surgery may be advised for some patients who continue to have TIAs. During the
operation, an artery on the outside of the scalp
is re-routed to the part of the brain that is not
getting enough blood flow. When blood flow
is restored, the brain works normally, and the
symptoms disappear. The hospital stay for
this type of bypass surgery is about one week.
For Strokes from Bleeding
Bleeding in the brain causes some strokes.
These strokes are called hemorrhagic (HEMer-RAJ-ik). The bleeding may occur when a
weakened blood vessel leaks or bursts. This
is called an aneurysm (AN-your-izm). When
an aneurysm occurs, the weakened artery may
become like a balloon filled with blood. Patients usually describe an aneurysm as the
worst headache of their life.
There are several types of surgery to repair
an aneurysm. A clip may be placed across the
neck of the aneurysm (like a clip at the end of
a balloon) to stop the bleeding. A newer approach is to thread a long, thin tube through
the artery that leads to the aneurysm. Then
a tiny coil is fed through the tube into the
aneurysm â balloonâ to fill the space and seal
off the bleeding. Based on the type of surgery,
the hospital stay ranges from several days to a
week or longer.
