What
is an aneurysm?
An aneurysm is a weakening in the wall of a blood vessel.
This results in the formation of a balloon like bulging in
the wall. Why do I need treatment for my aneurysm? Depending
on the clinical situation, there is a significant risk that
an aneurysm may rupture and cause bleeding. It has been shown
that cigarette smoking and excessive alcohol use increases
the risk of aneurysm rupture. The role of high blood pressure
is unclear, however, current evidence suggests there is a
may be a risk. Persons with a family history of aneurysm rupture
are also at an increased risk.
What is aneurysm coiling?
This procedure involves the use of a Guglielmi Detachable
Coil (GDC) made of a fine platinum wire to fill the inside
of the aneurysm thereby eliminating it from the circulation.
A successful coiling will prevent future aneurysm rupture.
How is this procedure performed?
This procedure is performed in an angiography suite. Often,
the patient is placed under general anesthesia. Using sterile
technique under X-ray (fluoroscopic) guidance, a fine catheter
is threaded from an artery in the groin all the way to the
inside of the aneurysm. Through this catheter the platinum
wire coil is then inserted.
How do I prepare for the procedure?
You will have to have an empty stomach, just like before an
operation. You may need to stay in hospital for a few days.
Please let the radiology scheduling clerk know if you are
allergic to radiographic dye. The procedure will be preceded
by a visit to the clinic where you will be seen by the interventional
neuroradiologist performing the procedure. Here, you will
receive detailed information on how to prepare, such as do's
and don'ts.
