Ruptured saphenous venous graft pseudoaneurysm presenting as a pulsatile chest mass

A 72-year-old man with prior history of coronary artery bypass grafting and sternal wire infection presented with non-ST-segment elevation myocardial infarction. His coronary angiogram revealed stenosis of the distal left main coronary artery (LMCA) and a pseudoaneurysm of saphenous venous graft (SVG) to right posterior descending artery. Patient developed ventricular fibrillation during admission, and postcardiopulmonary resuscitation, a pulsatile chest mass was observed which was diagnosed with computed tomography as a chest wall collection resulting from rupture of the pseudo-aneurysm. He underwent percutaneous coronary intervention of the LMCA with drug-eluting stents followed by successful coil embolization of the SVG pseudoaneurysm. Patient had an uneventful recovery postprocedure.
