Sequential bypass grafting is an effective method of myocardial revascularization in a number of situations where standard revascularization is not possible for a number of reasons (with atherosclerotically altered ascending aorta, hemodynamically significant lesions of the subclavian artery, deficiency of conduits, repeated operations of coronary artery bypass grafting, etc.). The subcutaneous vein is still widely used as an aortic/coronary artery shunt because of the ease of access, preparation and the possibility of use for multiple shunts. However, this type of shunt can develop intima hyperplasia and atherosclerotic lesions with an occlusion level of 10–15% in the first year after surgery. After 10 years, only 60% of venous shunts remain passable, of which only 50% have no signs of significant stenosis. There may also be complications in the lower limb where the fence occurred. The internal thoracic artery rarely develops atherosclerosis, and its diameter is usually comparable with the diameter of the coronary artery, which requires revascularization. In our case, the circumstances that led to the choice of the technique of sequential shunting were associated with a lack of conduits and the desire for more complete revascularization.
