Summary -
The
Merci
Retrieval
System™ (Concentric
Medical,
Mountain
View,
CA,
USA)
was
approved
in
2004
for
restoring
blood
flow
in
patients
experiencing
an
acute
stroke
who
are
otherwise
ineligible
for
intravenous
tPA,
or
in
whom
intravenous
tPA
treatment
has
failed.
However,
this
treatment
results
in
successful
recanalization
in
less
than
60%
of
treatable
vessels
(Multi
MERCI
trial).
We
describe
the
use
of
a
novel
device,
the
Solitaire™ AB
Neurovascular
Remodeling
Device
(ev3
Inc.,
Irvine,
CA,
USA)
that
received
the
CE
Mark
for
the
treatment
of
neurovascular
disease
in
2007
and
can
recanalize
arteries
when
MERCI
has
failed. We
describe
a
case
of
mechanical
thrombectomy
in
which
a
new
device,
Solitaire™ AB,
was
used
for
acute
cerebral
ischemia
in
the
setting
of
middle
cerebral
artery
occlusion
after
unsuccessful
recanalization
with
the
MERCI® Retriever.
Excellent
angiographic
and
good
clinical
results
were
obtained
without
any
complication. The
Solitaire™ AB
device
was
able
to
retrieve
and
remove
clots
efficiently
from
the
middle
cerebral
artery
when
the
MERCI
system
failed,
thereby
offering
a
new
alternative
in
the
treatment
of
acute
ischemic
stroke.
