Pseudoaneurysm following the Bentall procedure for acute aortic dissectiontype A: diagnosis using electron beam tomography

Pseudoaneurysms an a rare complication following replacement of the ascendi ng aorta or aorto-coronary bypass surgery. We report a case with replacemen t of the aorta ascendens, the aortic valve and venous aorto-coronary bypass grafting, in whom a pseudoaneurysm developed at the site of one proximal b ypass anastomosis. For the preoperative diagnosis, an ultrafast-CT (Electro n Beam Tomography, EBT) was done, as neither the pseudoaneurysm, nor the ve nous graft could be visualized by selective coronary angiography.
