Introduction The internal mammary arteries (IMAs) are commonly used as the conduit to bypass major coronary artery stenosis, and have shown greater long-term patency rates and improved survival as compared to saphenous vein grafts (SVGs) (1, 2).
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.

For many patients with coronary artery disease who undergo placement of a coronary artery bypass graft (CABG), employing the left internal mammary artery (LIMA) as a graft to the left anterior descending artery is a preferred strategy because of higher immediate and long-term patency rates. Debate exists concerning several factors, which include percutaneous coronary intervention (PCI) vs. CABG, single vs. bilateral mammary artery grafts, radial artery vs. saphenous vein grafts, right internal mammary artery vs. radial artery grafts, endoscopic vs.

artery [ahr´ter-e] a vessel through which the blood passes away from the heart to various parts of the body. The wall of an artery consists typically of an outer coat (tunica adventitia), a middle coat (tunica media), and an inner coat (tunica intima).

Det är lite svårt att veta hur man skall göra här. Mammary/mammaria är egentligen type B (ETB) receptor contraction and expression in the left internal mammary artery from patients with hypertension as compared to normotensive patients. Whereas the use of the left internal mammary artery as a conduit is associated with the highest 10-year patency rate (>90%), saphenous vein grafts - the most Coronary artery bypass surgery (Bypass using internal mammary artery and Bypass using saphenous vein).
Vein grafts have a higher risk of occlusion than internal mammary artery grafts with subsequently increased risk of death, myocardial infarction and repeat
Papaverine has been used by many surgeons to maximize mammary artery flow perioperatively, but the best delivery method is not known.
The lateral part of the breast receives blood from four vessels: Lateral thoracic and thoracoacromial branches – originate from the axillary artery. mammary artery’s origin is left intact; it remains a branch of the subclavian artery. Only the distal aspect of the artery is altered.

226-229. Arterial revascularization, and in particular, left internal mammary artery (LIMA), has shown to improve survival of patients with coronary artery disease. Complete revascularization often requires the use of other grafts and saphenous vein graft is still the most common conduit used. Results: Before removal of the left internal mammary artery, the blood flow was similar in the right and left peristernal wound edges, 2.5 cm from the edge (27 +/- 4 perfusion units (PU) on the right side and 32 +/- 3 PU on the left side, in muscle tissue). Internal-mammary-artery grafting for lesions of the anterior descending coronary artery is preferable whenever indicated and technically feasible.
