Rare case of concomitant coronary artery bypass grafting and open abdominal aortic aneurysm repair.

Coronary artery disease occurs when coronary vessels are unable to supply adequate oxygen to the myocardium, while an abdominal aortic aneurysm (AAA) is a dilatation of the abdominal aorta. Both conditions have similar risk factors such as smoking and hypertension. If these disease processes become severe and are left untreated, life-threatening consequences may occur. We present a 71-year-old male with prior myocardial infarction and an infrarenal AAA that underwent a rare combined procedure of coronary artery bypass grafting (CABG) and open AAA repair surgery. The CABG involved grafting the left internal mammary artery and saphenous vein to coronary arteries while the AAA repair used an 18-mm bifurcated aortic graft. Combined CABG and open AAA repair is complex and rare, but aims to reduce mortality and prevent aneurysm rupture in patients with severe comorbid conditions. The patient's positive postoperative outcome highlights the procedure's efficacy in select cases.
