Brain Aneurysm (cont.)
How is a ruptured brain aneurysm treated?
Emergency treatment for individuals with a ruptured cerebral
aneurysm includes restoring deteriorating vital functions such as
breathing and reducing pressure within the brain.
Surgery may be performed, usually within the first 3 days to clip
the ruptured aneurysm and reduce the risk of repeated episodes of
bleeding. Other measures may include bed rest, drug therapy, or blood
pressure control and fluids.
In some patients, including those for whom surgery is considered
too risky, the aneurysm may be treated by endovascular means
(endovascular means within the blood vessel).
What is endovascular treatment for a brain aneurysm?
Endovascular treatment of brain aneurysm is a procedure whereby a
catheter (tube) is inserted through the skin into a vessel and guided
up to the brain. The catheter is used to deliver a material that
travels through the blood vessel to clog or plug the blood vessel
(embolize). This specialized catheter procedure, called transcatheter
embolization, is a form of interventional radiology.
What is the microcoil treatment?
Metallic coils are among the newer methods for permanent
embolization. For instance, the Gugliemi Detachable Coil (GDC) is
made specifically to occlude (obstruct or plug) brain aneurysms.
Precise placement of the microcoil is crucial. An advantage of the
GDC coil is that it is "temporarily permanent." The coil can be
repositioned if is it not placed correctly the first time.
Microcatheters are an enabling technology in percutaneous (though-
the-skin) embolization, since they allow access to the deep tortuous
(winding or twisted) blood vessels of the brain and permit precise
positioning of the embolic material. This precision minimizes
interference with normal brain tissue.
What is the prognosis of a patient with a ruptured brain
The prognosis (outlook) for a patient with a ruptured brain
aneurysm depends on the extent and location of the aneurysm, the
person's age, their general health, and their neurological condition.
Some individuals with a ruptured brain aneurysm die from the initial
bleeding. Other individuals recover with little or no damage to the
nervous system. Early diagnosis and treatment are important in
preserving brain tissues from further injury.
