Cerebrovascular Aneurysm
Every
year, around 30,000 Americans will suffer a cerebrovascular aneurysm.
A cerebrovascular aneurysm is caused by a weakness in one of the blood vessels
in the brain, which is called an aneurysm. The weakness leads to a bulge
in the vessel and depending on the size of the neck will determine how
it can be treated. Almost 25 percent of all cerebrovascular deaths are attributed
to ruptured aneurysms.
The exact cause of a cerebrovascular aneurysm is unknown, though it is
more common in patients over the age of 30 years and almost twice as common
in women than in men. Once an aneurysm ruptures, blood will accumulate between
the brain and subarachnoid space. The blood will continue to collect and
damage the surrounding brain tissue.
Upon rupture, the cerebrovascular aneurysm requires immediate medical attention
to prevent further bleeding. If abnormal constriction of the blood vessels
of the brain results, additional tissue damage through a diminished blood
flow to the brain can be suffered, leading to serious neurologic impairment
or death. It is imperative that medical professionals stabilize the patient's
vital organ systems and try to avoid fatal results.
Since about 15 percent of patients with ruptured cerebrovascular aneurysms
die before getting to the hospital, the sooner proper treatment can be met
the better chances of survival there are. Even the patients that are able
to get medical attention will have difficulty surviving a ruptured aneurysm
and 20 - 40 percent of these patients will die. Medical professionals that
are able to effectively diagnosis and have immediate access to CT/MRI imaging,
in addition to other factors have been shown to have a higher success rate
in treating cerebrovascular aneurysms.
To prevent fatal outcomes, doctors can prevent the growth of the weak spot
expanding and eventually rupturing by immediately treating it. A cerebrovascular
aneurysm with a narrow neck can be treated non-surgically by diverting blood
flow away from the aneurysm using tiny metal coils to fill up the bulge.
In the past, an aneurysm with a wider neck usually required surgery to clip
off the bulge since the use of coils would fall out and end up causing stroke
risks by blocking the vessel.
Researchers at the University of Maryland have just introduced another
cerebrovascular aneurysm treatment option if a wider neck is present. The
introduction of a new wire mesh may be able to be put into the aneurysm
in order to keep the coils in place and allow for a much lesser invasive
surgery option. Whether or not the cerebrovascular aneurysm procedure will
become a popular option will remain to be seen.
