Why is internal mammary artery used in CABG?

Why is internal mammary artery used in CABG?

The internal mammary artery (IMA) grafts have been associated with long-term patency and improved survival as compared to saphenous vein grafts (SVGs). Early failure of IMA is attributed to poor surgical technique and less with thrombosis.

How long does a mammary artery bypass last?

Coronary artery bypass graft surgery usually lasts 3 to 6 hours. But it may take longer depending on how many blood vessels are being attached. Blood vessels can be taken from your leg (saphenous vein), inside your chest (internal mammary artery), or your arm (radial artery).

What is a mammary artery bypass?

As the most commonly used bypass grafts, the internal thoracic (mammary) artery (ITA) grafts show the best long-term results. In most cases, the artery is left intact at its origin, with the opposite end sewn to the coronary artery below the site of the blockage.

Which arteries are used for CABG?

There is a wide variety of vascular conduits available for CABG. The most commonly used are as follows: internal thoracic artery (ITA), saphenous vein (SV), radial artery (RA), right gastroepiploic artery (RGEA), and occasionally ulnar artery (UA), splenic artery, and inferior epigastric artery.

What does the mammary artery do?

The internal thoracic artery, aka the internal mammary artery, supplies the breast and the anterior chest wall. The internal thoracic artery travels along the inner surface of the anterior chest wall on both sides.

Why is the internal thoracic artery used for grafts?

Its survival and patency rates are much better as compared to venous and even other arterial grafts. Hence the IMA graft is considered to be the first choice conduit and the gold standard for coronary artery bypass graft.

Can I live a normal life after bypass surgery?

Summary: The prognosis following heart bypass surgery is both good and has improved over the past three decades. In fact, the survival rate for bypass patients who make it through the first month after the operation is close to that of the population in general.

What can you not eat after heart bypass surgery?

To keep blood vessels clear after bypass surgery, avoid foods high in fat and cholesterol, such as whole milk, cheese, cream, ice cream, butter, high-fat meats, egg yolks, baked desserts, and any foods that are fried.

What are the complications of CABG?

The major complications associated with CABG are death, myocardial infarction, stroke, wound infection, prolonged requirement for mechanical ventilation, acute kidney injury, and bleeding requiring transfusion or reoperation [1-4].

Why are veins used in CABG?

During coronary artery bypass graft (CABG) surgery, your surgeon will use a healthy blood vessel from another part of your body to create an alternate route, or bypass, around narrowed or blocked sections of your coronary arteries. This bypass surgery allows more blood to reach your heart muscle.

Where is mammary artery?

It is located about two to three centimeters on either side of the sternum and is slightly medial to the nipple. It is almost always accompanied by the large internal thoracic veins that also follow the same course. The internal thoracic artery runs under the fascia and deep to the intercostal muscles.
