All You Need To Know About The Operation Of Coronary Artery Disease


In coronary artery bypass surgery — also called coronary artery bypass grafting (CABG) — surgeons graft arteries or blood vessels healthy to the coronary arteries are damaged, beyond the area blocked by plaque. This procedure makes the blood through the arteries are exposed to, and increase the flow of blood towards the heart muscle.

Anyone who had to undergo coronary artery bypass surgery?

Bypass surgery is very effective in restoring angina symptoms if you have angina is stable.

When a coronary artery is partly blocked the main, or in the left main coronary artery occluded (which is the most significant coronary artery), or heart muscle is very weak, bypass surgery is able to prolong life compared to treatment with Angioplasty and stenting or by medical therapy. Bypass surgery can also be useful for people with acute coronary syndrome.

How to bypass surgery performed?

Bypass surgery performed under the influence of drugs. The surgeon splits to breast bone to open up the chest, and then stop the heart with chemical substances or the coolant (hypothermia) so that the physician is capable of grafting with the heart doesn't move. Blood circulation is maintained, while the heart is stopped, with pulmonary bypass machine. Once the grafts are completed, the heart started again.

Grafts used during bypass surgery normally comes from blood vessels feet (saphena vein), or chest wall arteries (internal mammary artery).

Grafting with arterial often last longer than the graft with blood vessels, arterial grafts and rarely lead to stenosis, unlike grafting blood vessels. So, the internal mammary artery grafts generally should be used if possible (as determined by the patient's Anatomy). Vascular grafts rather often lead to blockages due to atherosclerosis in 10-12 years of operation.

In recent years, a newer bypass surgery is being developed, called "minimally invasive bypass surgery". Minimally invasive procedure involves a smaller incision, as well as avoiding the use of a bypass machine. Unfortunately, the minimally invasive bypass surgery only for patients who fit a broken arterinya can be recovered in this way.

What are the possible complications?

Coronary artery bypass surgery is a major surgical procedure, and patients often don't return "normal" for weeks or even months after the operation. Reasonable if patients are loss of appetite, weakness, and pain at the incision for a few weeks. Depression often occur in 1-3 patients after surgery, and if not found and treated depression, recovery time will be much longer.

Other complications that might arise after bypass surgery include myocardial myokardia during or immediately after the operation (on less than 5% of patients), weakened heart muscle (often temporary), arrhythmia (atrial fibrillation prior), pleural effusion ( the buildup of fluid between the lung and the chest wall) the incision area, infection, and abnormalities of the cognitive (thought) called "pump head" (after "pump" bypass the pulmonary circulation supported grafts during the procedure, and that some people has assumed responsibility as the cause of cognitive changes).

Because bypass surgery has some risk, this operation is usually limited in patients who may be his life can be extended by surgery, or who failed to anginanya symptoms disappear despite undergoing medical treatment repeatedly.
