Internal mammary artery graft false aneurysm.

A 59-year-old male patient presented with a pulsating mass at the left sternal edge weeks after a CABG procedure. CTshowed a false aneurysm of the LIMA (Fig. 1), confirmed by angiography (Fig. 2a). The leakage was treated using a 16-by-3.5-mm Jostent leading to complete lesion thrombosis (Fig. 2b). Fig. 1. Contrast enhanced CT shows a 6 cm diameter left internal mammary artery false aneurysm. Fig. 2. Left internal thoracic artery graft angiograms. Note the vertical jet filling the false aneurism almost completely (a). Complete aneurysm exclusion immediately after the stent placement (b).
