-- Canine Ovariohysterectomy
midline incision is made slightly caudal to the umbilicus
through skin and subcutaneous tissues using a #10 blade
incision is made through the linea alba and enlarged with
scissors or scalpel.
horn of the uterus away from the surgeon is withdrawn
with a spay hook, and the cranial portion of the ovarian
suspensory ligament is detached from the body wall using
the forefinger (Figure 14) in order to expose the ovary
ovarian vessels are clamped with 2 carmalt clamps or hemostats,
and the ovarian pedicle is ligated with #2 catgut for
large dogs, #1 catgut for smaller dogs (Figure 16).
ovary (still attached to the uterus) is then severed from
the ligated pedicle between the two clamps placed above
the ligation (Figure 17).
forceps are used to hold the pedicle as the clamp is removed,
so that the pedicle may be inspected to insure there is
no bleeding before releasing the pedicle back into the
same procedure is applied to the 2nd ovary.
horns are elevated until the uterine body is exposed. Two
clamps are applied above the cervix, and the uterine body
is ligated with catgut (Figure 18).
body (and horns) of the uterus is severed above the ligation;
again, thumb forceps are used to hold the pedicle as the
clamp is removed, so that the pedicle may be inspected to
insure there is no bleeding before releasing the pedicle
back into the abdomen (Figure 19).
midline is sutured with 4-0 stainless steel (Figure 20)
using simple interrupted sutures (Figure 21).
skin incision is also closed with 4-0 stainless steel (Figure
should be loose enough to allow for skin swelling (Figure
subcuticular skin closure may be performed using PDS #2-0
(a continuous pattern may be used); or Nexaband can be used
to close very small skin incisions (<2cm) in puppies
