| The
cerebral aneurysms are dilations of the arteries
that cause brain hemorrhage.
Abundant subarachnoid hemorrhage in
TAC
They
can present in any age, but mainly after the 50
years, and exists a greater predisposition in females.
It is considered that 50% of the patients die before
arriving at the Hospital, representing one of the
more frequent causes of sudden death in the adult.
These
injuries are located mainly in any cerebral artery
but in those related to the well-known Circles of
Willis such as internal carotid, middle cerebral
and anterior cerebral artery as well as anterior
communicating artery that corresponds to anterior
circulatory circuit. In the posterior region they
are observed above the posterior cerebral artery,
vertebral and basilar arteries, mainly. Nevertheless,
the frequency of these injuries in the later circulation
is less frequent.
 
The
cardinal symptom is the sudden headache and corresponds
to the worst and most intense pain ever experienced.
Additionally, the patients can present seizures,
paralysis of cranial nerves and also coma.
The diagnosis
is made by means of specific exams such as:
- Cerebral
Angiogram with digital subtraction
- Magnetic
angiogram
- Cerebral
angiotomogram
The
treatment of the cerebral aneurisms is always based
on surgery through a craniotomy for clipping using
a Titanium device or by endovascular therapy using
for metallic filaments (coils). The best treatment
must be made during the first later days to avoid
rebleeding and the high possibility of developing
spasms of the arteries (vasospasm), which would
complicate the clinical picture aggravating its
prognosis.

The
prognosis of the aneurysms depends on the patient's
state in the moment before the surgical treatment.
