Key result
Routine preoperative internal mammary artery angiography is warranted before coronary bypass surgery to identify rare anomalies like an origin from the left subclavian artery-aorta junction.
Why the study?
Anomalous origins of the internal mammary artery and related pathologic conditions suggest the need for routine preoperative angiography before coronary artery bypass surgery.
Highlights a rare anatomical anomaly and suggests the potential utility of routine preoperative internal mammary artery angiography before coronary artery bypass surgery.
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.
