title: Multiple coronary artery aneurysms resulting in myocardial infarction in a young man: treatment by double aorta-coronary saphenous vein bypass grafting.
abstract: A 26-year-old Japanese man was treated for a transmural myocardial infarct caused by multiple aneurysms of the left main (LMC), left anterior descending (LAD), and the right coronary arteries (RCA). He underwent successful double aorta-coronary saphenous vein bypass grafting. The etiology of the aneurysm remains uncertain but an inflammatory origin is most probable. Review of the literature has indicated that this is the seventh case of coronary artery aneurysms without arteriovenous fistulas to be managed by grafting techniques with the saphenous vein. This experience has suggested that young patients presenting with anginal pain or myocardial infarction whould be carefully examined for coronary artery aneurysms. Since most of the patients developed myocardial infarction probably from thrombotic occlusion or embolism of the distal vessel, this lesion should be considered for surgery whenever anatomically feasible. Coronary artery reconstruction by grafting techniques, with or without resection of the aneurysm, is the treatment of choice. Although surgical treatment has provided good clinical amelioration to our patient as well as the patients previoulsy reported, a careful long-term follow-up should be continued for patients with multiple coronary artery aneurysms of doubtful origin.
