Coronary Artery Bypass Graft
Coronary Artery Bypass Graft (CABG) also called coronary
artery bypass surgery is performed on patients who have
suffered a heart attack. It is generally restricted
to severe heart block cases that have not responded
to medication or angioplasty and/or stenting.
THE PROCEDURE
In a CABG, the blood flow is redirected through a new
artery or vein that is grafted around the blocked parts
of coronary arteries with an aim to improve blood circulation
to the heart. The procedure conventionally involves
an open-chest surgery and the placing of a heart-lung
bypass machine to ensure blood and oxygen circulation.
The new artery or vein is grafted with an artery or
a vein from some other part of the body such as the
leg.
TYPES OF CABG
Less invasive techniques have replaced the conventional
open-chest surgery nowadays, though a lot more research
is required. Some of them are:
– |
Use of drugs that slow down the heart
and do not require a heart-lung bypass machine |
– |
Keyhole or minimally invasive procedures that
may not require a heart-lung machine |
POST SURGICAL CARE
The patient must stay under observation for around 2
days to a week in the Intensive Care Unit (ICU), unless
there are some complications. Aspirin is administered
right after surgery to check complications. After that,
recovery is speeded up with a physical routine, respiratory
rehabilitation, job-related routine and diet management.
A patient takes around 4 to 6 weeks to be active at
home; exercise and driving is allowed after about 2
to 3 weeks; and one can return to work usually within
1 to 2 months depending on their kind of profession.
EFFECTIVENESS
CABG vis-a-vis angioplasty shows almost identical long-term
results. CABG may show greater resilience and more comprehensive
revascularization.
CABG as a rule is more effective in patients with diabetes, left main coronary artery ailments, frail heart muscle and valve ailments that are surgical cases.
COMPLICATIONS
Some of the risks and disadvantages are as follows:
– |
Return of chest pain or angina is
the commonest of post surgery complications |
– |
Re-operation is also often necessary in some cases
after 5 years |
– |
Anesthesia risks |
– |
Heart attack |
– |
Stroke |
– |
Excessive bleeding |
– |
Infection |
– |
Long-term memory loss |
– |
Problems in comprehension, calculation skills |
– |
Lack of concentration |
– |
Death |
