THE'TO
AND
FLOW'
OF
BLOOD VESSEL CLOTS
(EMB0LTSM)
There are 3 aspects of prevent-
ing blood vessel clots: moderate physi-
cal
excercises, low-fat
diet
and vitman
and
fibre-rich food and prompt manage-
ment of atrial fibrillation (tremour
of
heart chamber)-
the
source
of
many
emboli(clots).
Emboli would form when
there
is slowing down
of
blood flow.
Emboli
travel with the
blood along
the
artery and
may
get stuck at
a
smaller
arterial
branch
to
cause thrombosis
(blockage of the whole
artery).
Typical
examples of embolic
symptoms are
limb pain, bruising, toe pain, pallor and
numbness, calf pain,
etc.
A
few days
later,
tissue necrosis (tissue death) sets
in and
the
limb may have
to
be
ampu-
tated
surgically.
When signs of embo-
lism occur, general hospital manage-
ment
with Doppler ultrasound,
CT
scan,
magnetic resonance
imaging
arteriography, etc., are recommended.
Treatmant mainly
consists of
anti-
coagulants
like
warfarin, heparin
and,
more
recently,
low-molecular
heparin.
Surgery consists of various methods
like
compression
by
an internal balloon
or extraction of the clot.
