Case Description
A 52-year-old gentleman, with several cardiovascular risk factors was referred for surgical management; other history was notable for end stage renal disease with a left upper limb fistula, severe peripheral vascular disease, and Protein C deficiency resulting in recurrent deep vein thrombosis requiring a greenfield filter. He had undergone coronary artery bypass grafting five months prior with LIMA-LAD, and saphenous vein grafts to posterior descending artery and ramus intermedius complicated by left arm ischemia requiring angioplasty. He had re-presented at an interval with progressive dizziness, fatigue, and lightheadedness. Computed tomography (CT) imaging revealed an aortic pseudoaneurysm at the original aortic cannulation site with an ostium of 9 x 7 mm that was compressing 50% of the main pulmonary artery (figure 1A).
