Thrombotic thrombocytopenic purpura (TTP) following coronary artery bypass: case series and review of the literature.

We reviewed 10 cases of thrombotic thrombocytopenic purpura (TTP) following cardiac surgery since November 1998. The object of the study was to define the natural history of post-CABG-TTP and to assess response to therapy. All patients underwent CABG; four also underwent aortic valve replacement and six mitral valve replacement.
