The traditional and most common method of
performing anastomosis typically involves tedious and time-consuming hand-sewn
placement of individual stitches with a continuous suture to connect the bypass
graft proximally to the aorta and distally to the coronary vessels. Anastomosis
is viewed by surgeons as the most critical step in performing CABG procedures,
and using traditional methods, the process can take 10 to 25 minutes to perform
the necessary suture for each point of anastomosis.
Most surgeons prefer to use a continuous
suture because placement of sutures individually is considered to be more
challenging and time-consuming. Whether the procedure is on-pump or off-pump,
hand-sewn proximal anastomosis generally requires clamping of the aorta, which
carries the risk of neurological damage and other serious adverse effects.
Although methods to allow hand-sewn proximal anastomosis without clamping have
been developed, the time-consuming nature of manually applied sutures and the
limitations associated with their use have fueled the need for fast, efficient
and reliable automated systems to hasten and facilitate anastomoses done during
CABG procedures.
Thus, AADs have been developed for this
purpose and replace the need for surgeons to manually hand suture two blood
vessels to perform the anastomosis. The growing popularity of AADs has helped
to significantly reduce surgical procedure times. In addition, AADs have significantly
reduced the inherent difficulty in performing anastomosis in beating-heart
procedures.
Anastomosis assist devices (AADs) are used
for joining two blood vessels, usually to restore continuity after resection,
or to bypass an unresectable disease process. Coronary artery bypass graft
(CABG) involves the construction of an alternative path to bypass a narrowed or
occluded diseased coronary artery and restore blood flow from the aorta to an
area beyond the occlusion. This is accomplished by using harvested veins or
arteries as bypass grafts. This harvested vessel is usually the saphenous vein
in the leg, the radial artery in the arm or the mammary artery from the chest
wall.
One end of the harvested vessel is then
generally attached to the aorta (proximal anastomosis) and the opposite end is
attached to the target coronary vessel on the heart (distal anastomosis). If
the mammary artery is used as the bypass graft, it is dissected from the chest
wall, leaving the blood inflow end in place, while the opposite dissected end
is attached to the target vessel. This provides uninterrupted blood flow and
eliminates the need for proximal anastomosis to the aorta. Regardless of the
type of vessel used, once in place, these grafts provide sufficient blood flow to
bypass the narrowed or occluded portion of the coronary artery.
