Surgical revascularization for 'atherosclerotic' coronary artery aneurysms associated with multiple obstructive coronary artery disease.

Coronary artery aneurysms (CAA) were originally described in a series of post-mortem studies but are now more commonly observed during the widely used coronary angiography. This article reports on four adult patients with CAA associated with obstructive coronary atherosclerosis. Arterial and venous conduits were successfully performed in all four. The aetiology and treatment are discussed.
