Because of the complexity of bypass surgeries, it is important to identify any contraindications that might result in complications during the surgery. Continue reading down below if you want to learn about Coronary Artery Bypass Graft (CABG) contraindications and who can or cannot go through the surgery.
A Coronary Artery Bypass Graft is done in order to treat blockages in the major blood vessels around the heart. In most cases, the blockage is caused by the build-up of plaque in the arteries (atherosclerosis), and the graft is done in order to bypass it.
It’s not the only treatment available, but it is the one most recommended for patients dealing with multiple blockages. If a patient is in the early stages, other treatment plans like stenting (which is associated with less risk and is considered far less invasive) or medical therapy might be recommended instead.
The procedure is known to have high success rates and is believed to be able to extend a person’s life for several decades. However, there is still a calculated 2-3% chance of death post-surgery and the complexity of it has been known to result in other complications.
What to Tell Your Doctor
Pregnant women (or women who suspect that they might be pregnant), or women who are lactating or breastfeeding should inform their doctor immediately before undergoing a CABG surgery.
The same thing goes for patients who might be allergic to some of the medications involved in the procedure or the contrast dyes that are used in order to identify the blockages in the body. Any allergies or sensitivity to iodine, shellfish, or latex should also be reported prior to the operation. These conditions can potentially hold up the surgery but will not necessary permanently prevent a patient from going through the surgery.
As for CABG’s actual contraindications, there are surprisingly few. The first of which involves asymptomatic patients who show little risk for Myocardial Infarction (MI) or Death. This is not an absolute contraindication, as the progression of the disease may heighten the risk over time, but there is little need for the surgery if the risk does not exist.
The other contraindication of note is a person’s age. Older people are more likely to require CABG, but according to this study, patients that are incredibly advanced in age (at least 85 years old and older), will still experience more risk – although said risks have been lessened over time with the application of modern medical technology.
Conclusion: Coronary Artery Bypass Grafting Contraindications
A Coronary Artery Bypass Graft is so complex that contraindications are to be expected. However, there is no denying the benefits of choosing surgery over living with coronary artery disease. If you have any concerns about whether or not you will be able to undergo the procedure safely, the best thing to do will be to discuss your chances with a medical professional. The sooner that you do so, the earlier that your procedure can be scheduled and planned.
