A technique to harvest the inferior epigastric arteries for coronary bypass procedures
1Division of Cardiothoracic Surgery, UCLA Medical Center 90024.
The demonstrated superior long-term patency of the internal mammary artery (IMA) over the saphenous vein (SV) has prompted the use of other arterial grafts, particularly for younger patients and patients without a suitable SV. We have used the single or bilateral inferior epigastric arteries (IEA) as a detached arterial conduit in 27 patients undergoing coronary artery bypass operations (CABG). In this report we describe the surgical anatomy of the IEA, preoperative noninvasive evaluation by duplex scan, our harvesting technique, and early surgical experience.
