ABSTRACT
Background:
Superficial
palmar
arch
is
the
dominant
vascular
structure
in
palm
formed
by
the
anastomosis
between
superficial
branch
of
ulnar
and
superficial palmar branch of radial arteries.
Purpose of the study
: To know the different anatomic patterns in the formation of superficial palmar arch in humans and their clinical implications.
Materials
and
Methods:
The
study
included
50
hands
from
human
cadavers
from
Department
of
Anatomy,
Mysore
Medical
College
&
Research
Institute,
Mysore
and
Sree
Narayana
Institute
of
Medical
Sciences,
Ernakulum.
The
specimens
were
fixed
with
10%
formalin
solution
and
morphology
of
superficial
palmar arch was observed for different patterns.
Results:
In
the
above
study,
different
variants
of
superficial
palmar
arch
were
observed.
88%
of
specimens
were
of
complete
and
12%
were
incomplete
type
of
arch.
The
different
morphological
variants
were
grouped
according
to
the
classification
provided
by
Coleman
and
Anson
in
1961.
42%
of
specimens
belonged
to
type-A
variety
in
the
formation
of
superficial
palmar
arch,
26%
to
type-B,
4%
to
type-C,
6%
to
type-D,
10%
were
of
complete
arch-
(not
in
the
classification), 4% to type-F, 6% (rare variety) and 2% to type-H variety.
Conclusion:
The
present
study
revealed
details
about
different
patterns
of
vascular
anastomosis
which
helps
in
knowing
the
importance
of
arches
in
cases
of
reconstructive
hand
surgeries,
preoperative
screening
of
radial
artery
harvesting
for
myocardial
revascularisation
and
arterial
interventions
that
include
radial artery cannulation and radial artery arm flap. Lack of knowledge of different patterns might complicate reconstructive hand surgeries.
