Nonmycotic false aneurysm of aortic cannulation site

Case Reports

Nonmycotic false aneurysm of aortic cannulation site presenting 26 years postoperatively.

We report the case of a 64-year-old woman who presented with a false aneurysm in the ascending aorta where arterial cannulation was done in an operation 26 years earlier. The aneurysm was excised with the ascending aorta and successfully replaced with a prosthetic graft during deep hypothermic circulatory arrest and retrograde cerebral perfusion, accompanied with concomitant procedures of mitral valve replacement and maze procedure. When the aneurysm, 3.5 x 3.0 x 4.5 cm, was removed, it showed a remarkable sharp line of demarcation between the normal aorta. Microscopic examination of the specimen was consistent with the features of a pseudoaneurysm.
