The
conventional method of CABG was the On-pump Heart
Surgery, in which a heart-lung machine (known as
the pump) takes over the function of the heart
and lungs during the operation. However, this on-pump
procedure presents risks to body systems as follows:
- Heart function (heart failure, Cardiac
arrhythlmia, necrosis)
- Blood coagulation (haemophilia)
- Immunity
- Lung function (decrease in lung flexibility
caused by over 2 hours of on-pump surgery)
- Central nervous system (Embolism may
result, causing complications to the brain.)
- Kidney function (Renal failure may occur.)

In addition, the use of femoral vein as
a bypass conduit will cause an
unsightly scar.
To satisfy the patient's needs and to ensure their
optimum satisfaction, new technology and surgical
techniques are nowadays employed, resulting in
smaller wounds, fewer scars, less pain and faster
recovery.
Transesophageal
Echocardiogram
In an off-pump heart surgery, a device
called Cardiac Stabilizer is used to
secure the area of the heart where an
artery is to be bypassed while the rest
of the heart continues to beat. This
method offers reduced complications occurring
from the use of heart-lung machine. Other
advantages involve the need for a smaller
amount of blood as well as the reduced
length of operation time, anesthesia
period and recovery, all of which result
in lower expenses.
This technique is suitable for senior patients,
patients with high risks and those with complications. |
All
Arterial Conduits
The use of all-arterial conduits for coronary
artery bypass graft has been widely recognized
as beneficial to the patients in the long
run. Most commonly, the arterial conduits
used in this method are the left internal
mammary artery (LIMA), the right internal
mammary artery (RIMA) and the left or right
radial artery (RA). The studies conducted
over ten years period reveal that the patency
rate of the LIMA falls between 90-95% whereas
that of the vein graft stands at only 60
%. |
Minimal
Invasive Cardiac Surgery
This approach causes
the least effect on heart
tissues with no need
of opening the sternum
to perform the surgery,
thus resulting in less
post-surgery pain, small
wounds and no scars. |
Ever since 2004, when Phyathai 2s Heart Center
adapted these techniques for use in heart surgery,
no serious complications have been found. Nonetheless,
which technique to choose depends on doctors discretion
and the condition or symptoms of an individual
patient. For medical consultation, you can contact
the Heart Center, Phyathai 2 Hospital everyday
for an appointment with our cardiologists. |
