Posttraumatic coronary artery aneurysm.

A 31-year-old man sustained blunt deceleration trauma with dissection of the left anterior descending coronary artery. We repaired a posttraumatic coronary aneurysm to prevent late occlusion of the recanalized vessel. An internal mammary artery graft was applied as a precaution against postoperative thrombosis. Follow-up at 12 months showed improved left ventricular function.
