Congenital coronary aneurysms nine years following saphenous vein bypass graft surgery.

A 34-year-old woman with two congenital coronary aneurysms received a saphenous vein bypass graft (SVBG) as treatment for a thrombosed right coronary artery aneurysm 9 years ago. The angiographic and surgical findings were reported at that time [1]. In 1979, she received a sequential SVBG to the left anterior descending and first diagonal coronary arteries following recurrence of angina and progressive occlusion of the left coronary artery aneurysm. She is believed to have the longest angiographically documented course following operation, and her case history is reported to aid in establishing the natural history of this unusual condition and its surgical management.
