bypass injertoAlso known as coronary artery bypass grafting or surgical myocardial revascularization, it is used to treat an obstruction in the irrigation of the coronary arteries usually caused by atheroma, through which a portion of another vein is taken, and one end is attached to the aorta artery to provide blood supply and the other end is attached to the to the coronary sector that is beyond the obstruction.


The most common symptom of coronary atherosclerosis is angina pectoris. When it occurs gradually, the cardiologist can request a nuclear medicine study called SPECT where the extent and severity of the disease can be observed. Catheterization provides the diagnosis where the location, number and type of obstruction can be determined and the type of treatment can be defined.

Bypass surgery is recommended for the following:

  • Obstruction of the trunk of the left coronary artery.

  • Proximal obstruction of two or three epicardial arteries (right, circumflex or anterior descending coronary artery).

  • Obstruction of the proximal left anterior descending artery where a coronary angioplasty is impossible to perform.

Before surgery, patients are required to undergo a physical examination to detect coexisting illnesses. Different laboratory, physical, radiographic and other studies are also carried out to prevent complications and plan a strategy in the event of an accompanying disease. Patient control during surgery has been improved by the development of electromedicine; the anesthesiologist will continuously monitor your vital signs and anesthetic depth.


The internal mammary artery, which is located in the thorax, is commonly used to replace obstructed arteries; it does not have a vital function. The radial artery, which is extracted from the arm, is also used. For bridges, it is necessary to enter the chest by median sternotomy (large incision through the sternum). This method is safe and allows the surgeon to perform complex procedures. Bridges can be performed with or without extracorporeal circulation depending on the complexity of the procedure and the characteristics of the individual patient.


The patient spends the first 24 hours in cardiovascular recovery, and then, he spends the 2nd and 3rd day in the intensive care unit. The patient is transferred to intermediate care where he spends the 4th and the 5th day. The patient is usually discharged starting from the 6th day.
