Self-apposing stent-assisted coil embolization for the treatment of coronary artery aneurysm.

Coronary artery aneurysms (CAA) represent an uncommon disease with yet unclear standards of treatment. Clinical and anatomic characteristics determine choice of treatment. Stent-assisted coil embolization has been described as a valuable option for management of patients with wide-neck coronary aneurysms. Choice of appropriate stent sizing can be challenging particularly when there is a large difference between proximal and distal diameters. We report a case of stent-assisted coil embolization of a coronary aneurysm using a self-expandable stent. This type of stent can be helpful to treat CAA involving coronary sites where marked tapering of vessel diameter is often present.
