How is internal mammary artery harvested?

As the fascia is pulled down with forceps, the vein is exposed using the electrocautery tip. When the under-surface of the vein is clearly exposed, the artery subsequently becomes visible. The cautery tip gently separates the vein and IMA. The trunk of the IMA is separated from the chest wall gradually.

What is internal mammary artery graft?

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 artery is used for grafting?

Internal thoracic arteries (also called ITA grafts or internal mammary arteries [IMA]) are the most common bypass grafts used. They are the standard of care, and the goal is to use these arteries for every patient who has isolated coronary artery bypass surgery.

What does internal mammary artery supply?

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. The internal thoracic artery runs under the fascia and deep to the intercostal muscles.

Which artery is used in CABG?

Your doctor uses coronary artery bypass graft surgery (CABG) to treat a blockage or narrowing of one or more of the coronary arteries to restore the blood supply to your heart muscle. Symptoms of coronary artery disease may include: Chest pain.

What should you know about left internal mammary artery harvesting?

Care should be taken when opening the retractor as the lower part is pushing on the right ventricle and this may cause hemodynamic instability in a fragile patient. The pleura is then freely dissected from the chest wall. Superiorly, the subclavian vein should be exposed clearly.

Which is the best artery for CABG surgery?

The left internal mammary artery (IMA) and saphenous vein are the most commonly utilized conduits in CABG surgery and are still considered to be the gold standard by most surgeons.

What happens to the internal mammary artery during mobilization?

Because the internal mammary artery is a delicate structure, any undue stretching, clamping, or misplaced clips results in permanent vascular injury and therefore unsatisfactory short- and long-term results. Excessive traction during mobilization should be avoided as it can lead to dissection of the vessel wall.

Who is the father of bilateral internal mammary arteries?

Reports about the application of bilateral internal mammary arteries (BIMA) for myocardial revascularization can be traced back to the sixties, when Rene Favalaro, considered the ‘father’ of coronary surgery, described the technique and outcomes of BIMA implants into the myocardium [6], [7].
