What are the advantages of using IMAs in CABG procedures?
IMAs (Internal Mammary Arteries) are superior to SVGs (Saphenous Vein Grafts) in CABG (Coronary Artery Bypass Grafting) procedures due to their decreased likelihood of ischemic events and prolonged survival. Additionally, IMAs are more resistant to spasm and have higher patency rates than other arterial conduits such as the radial, gastroepiploic, and inferior epigastric arteries. Furthermore, the use of IMAs is associated with a decreased incidence of sternal wound infections in patients with diabetes mellitus and those who are obese.
