9.7.2 Anastomosis of the arterial cannula
Aorta
INSTRUCTION
1. Tangentially clamp the ascending
aorta and make a longitudinal
opening of a length which is suit­
able for the cannula diameter. If
necessary, offset the incision later­
ally to the right by up to 45°.
2. Anastomose the cannula using ten
teflon-backed double-reinforced
individual monofilament (e. g. 4-0
EB) U-sutures. (If simpler condi­
tions are encountered, a running
suture can be made instead.)
3. Remove all air from the cannula
and use a tube clamp to clamp the
cannula below the anastomotic site.
If it is necessary to clamp any other
part of the cannula that is not cov­
ered with velour, cover the part of
the cannula that will be clamped
with a gauze sponge.

INSTRUCTION
1. Make a longitudinal incision of a
size suitable for the cannula diame­
ter in the pulmonary artery.
2. Anastomose the cannula using 10
teflon-backed, double-reinforced
individual monofilament (e. g. 4-0
EB) U-sutures. (If simpler condi­
tions are encountered, a running
suture can be made instead.)
3. Remove all air from the cannula
and use a tube clamp to close it
below the anastomosis. If it is nec­
essary to clamp any other part of
the cannula that is not covered with
velour, cover the part of the cannula
that will be clamped with a gauze
sponge.
