Mini Stroke- Transient Ischemic Attack (TIA)
Mini Stroke- Transient Ischemic Attack (TIA)
Dr. Fritz Schmutz, MD, Interventional Radiologist practicing at Eastern Idaho Regional Medical Center, talks about mini strokes, also known as transient ischemic attacks (TIA). Mini strokes are warning signs of a full-blown stroke event and a patient should immediately go to a Primary Stroke Center to be evaluated by stroke specialists.

13.42 -> - A mini stroke is a common expression
15.73 -> that people use for what
is more formally called
18.16 -> a transient ischemic attack.
20.72 -> A transient ischemic attack
refers to the fact that
23.7 -> it is temporary, it's
transient, by definition
26.74 -> lasts less than 24 hours.
28.91 -> Ischemic in that the presentation
31.04 -> is based on decreasing
blood supply to the brain,
34.67 -> that's why you're having that event,
36.97 -> and the attack is the
description of the event,
39.87 -> like the loss of speech,
41.42 -> loss of vision, loss of
strength, loss of sensation.
48.584 -> People are often not sure
what's happening to them,
51.88 -> they lose vision, a gray
area comes over their eye
56.14 -> temporarily, or they can't speak for
59.06 -> a matter of minutes or an hour.
61.22 -> Or they become weak or numb
in one side of their body.
64.39 -> Those are common presentations
for so-called mini strokes.
68.29 -> Any of those mini strokes are
warning signs that something
72.16 -> is allowing clots to block arteries or
74.666 -> something else blocking arteries.
77.4 -> If you have one of those
transient ischemic attacks,
80.75 -> even if they completely
resolve, don't excuse them.
83.87 -> That's a warning sign that you need to be
85.7 -> evaluated for a source of stroke.
87.943 -> They predict full-blown
strokes in individuals.
93.28 -> When you've had those warning signs,
95.52 -> wisdom dictates that you're evaluated.
98.34 -> Usually that initial evaluation
is an ultrasound examination
101.85 -> to look for the most
common source of strokes,
104.58 -> which is in the carotid artery.
106.73 -> About 75% of strokes are due to disease
110.25 -> in the carotid arteries.
111.54 -> 25% are due to disease in the heart.
114.73 -> So an ultrasound examination will evaluate
116.9 -> the carotid arteries first.
118.81 -> If you find significant
blockages, then you consider
121.74 -> the treatment options.
123.18 -> There are mainly two:
one is an open surgery,
126.03 -> a so-called carotid endarterectomy,
where you open the skin,
129.25 -> dissect down onto the artery,
open the artery carefully,
133.75 -> take out the blockage
and re-close the artery.
137.07 -> The other strategy is to
do, through the vessels,
140.96 -> placement of a stent, which
involves again the use of
144.55 -> tubes in the artery, the use of stents,
146.59 -> which is a metallic frame
placed inside the blockage
150.27 -> and expanded to re-open the artery
152.34 -> and blood supply to the brain.
157.402 -> EIRMC is a hospital that
has been certified as a
159.81 -> Primary Stroke Center,
and so they have the tools
163.06 -> and the personnel to have
this immediate intervention
166.24 -> to these strokes and minimize
the impact of the stroke.
169.562 -> My societies have been
trying to encourage people to
173.65 -> develop those tools and
that personnel, but frankly
177.33 -> this institution here is probably
the one that has the tools
180.32 -> and the personnel to handle the region,
182.46 -> which is appropriate.
