title: False aneurysm of the right internal mammary artery. Late rupture after sternotomy.
abstract: This report describes a late, near-fatal rupture of a false aneurysm of the right internal mammary artery subsequent to coronary artery bypass grafting. The patient presented to us in shock due to hemorrhaging, 8 weeks after bypass surgery that had been complicated by sternal fracture, dehiscence, and infection. Emergent thoracotomy and suture ligation controlled the hemorrhage. To the best of our knowledge, this is the 1st reported case of late massive hemorrhage caused by injury to an internal mammary artery after sternotomy. The literature is reviewed and discussed.
