A 78-year-old man with mitral regurgitation incidentally diagnosed with aneurysm of the left internal thoracic artery (LITA) and several internal thoracic artery-pulmonary artery (ITA-PA) fistulas originating from the aneurysm. To prevent rupture of the aneurysm, ITA ligation was performed during surgery for the mitral valve. Because of the complex anatomy surrounding the aneurysm, the main duct of the ITA was ligated at the peripheral and center of the aneurysm, then arterial fistulae were resected as many as possible. Postoperative computed tomography (CT), however, showed patent LITA and contrast material in the aneurysm. Second stage coil embolization procedure was performed with successful results. Intravascular treatment is effective for ITA aneurysms or ITA-PA fistulae because we can clearly visualize and confirm blood flow during operation.
