Definition
English
:
Abnormal formation of
blood vessels
that shunt arterial
blood
directly into
veins
without passing through the
CAPILLARIES
. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital
arteriovenous fistula
. The lack of
blood
flow and
oxygen
in the
capillaries
can
lead
to tissue damage in the affected areas.
