title: Anomalous origin of left internal mammary artery from the lateral junction of the left subclavian artery and aorta.
abstract: We describe the first reported case of an internal mammary artery originating from the junction of the left subclavian artery and aorta. Noting this, along with other reported anomalies and various pathologic conditions, it appears warranted to perform routine preoperative internal mammary artery angiography before coronary artery bypass surgery.
