Coronary artery aneurysms are often discovered incidentally during coronary angiography. The prognosis and other factors are unknown, and the optimal treatment methods have not yet been determined. In this report, we performed coil embolization in three patients with coronary artery aneurysms. The three cases consisted of two males and one female. One case was a pseudoaneurysm resulting from coronary stenting, while the other two cases were saccular aneurysms arising in the left coronary artery bifurcation. In the case of a wide-neck aneurysm, a coronary stent was used to assist in filling the coil; however, it did not completely prevent coil protrusion from the stent strut and additional stenting was required. Optical coherence tomography clearly demonstrated coil prolapse and it proved to be useful for evaluation. Coil protrusions can lead to restenosis. Despite the non-selection of a covered stent due to bifurcation, the potential for covered stenting in a manner that would preserve the side branch was considered as a means of averting coil prolapse. It is therefore imperative to emphasize that ongoing follow-up is essential to substantiate the long-term prognosis of the patients.
