00:00Give me 60 seconds and I'll explain what a brain aneurysm is.
00:03Hello, my name is Juan Andrés Mejía and I am a neurointerventional radiologist at the Santa Fe Foundation in Bogotá.
00:09A cerebral aneurysm is a dilation of the arteries in the brain.
00:14What happens with this? It's a wall that weakens in the artery, it bulges.
00:20And it is this area that can become susceptible to rupture and cause bleeding.
00:27or commonly known as a stroke.
00:30The main risk factors are smoking, high blood pressure,
00:36Genetic and hormonal factors; in other words, there are a large number of risk factors.
00:41which makes it difficult to detect without prior symptoms.
00:47Cerebral aneurysms are usually detected incidentally.
00:51in diagnostic studies requested for another condition.
00:55And why are we interested in discussing them?
00:58Because if it ruptures, the morbidity and mortality, that is, the aftereffects that can result.
01:05or the death rate of patients is very high.
01:09This, for example, is a large aneurysm in an artery that leads to the brain,
01:14which is the internal carotid artery.
01:16Here we see how this large dilation of the normal arterial wall exists.
01:21Within the dilation we see another second dilation, which is a kind of weakness
01:26within the weakness, and this makes it much more susceptible to a rupture.
01:32We have three-dimensional reconstructions that help us to pinpoint the exact location
01:38the site of the aneurysm in relation to the patient's skull.
01:42For this particular aneurysm, we use a stent that is inserted inside the artery.
01:48at the same time as the metal coils that fill the aneurysmal sac.
01:53In conclusion, this is the configuration we have with the stent protecting the artery
01:59and the coils within the aneurysm that stabilize its treatment.
02:04At the end of the procedure, we have a before and after with the aneurysm completely secured.
02:11and with a fairly considerable decrease in the probability of breakage.
02:18Thank you!
