Abstract

A 28-year-old man with a huge subepicardial hematoma of the right atrium, which is so rare that a review of the literature has failed to disclose similar case, is reported. Suspecting of rhabdomyoma, we excised free wall of the right atrium and a part of lateral wall of the superior vena cava. The excised part was reconstructed with expanded polytetrafluoroethylene (Gore tex). This synthetic material has a few merit and application of this one to the reconstruction in the venous system seems more promising. He was discharged with a regular sinus rhythm, normal heart size three months after the operation. The histologic examination of the excised material revealed amorphous blood clots and chronic granulation tissue containing hemosiderin-cells. The cause of the hematoma was not clarified even by microscopic examination.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
