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.
报告了一名28岁男性，其右心房存在巨大的心外膜下血肿，这种情况极为罕见，文献检索未发现类似病例。怀疑为横纹肌瘤，我们切除了右心房游离壁及上腔静脉部分侧壁。切除部分用膨体聚四氟乙烯（戈尔特斯）进行重建。这种合成材料有一些优点，将其应用于静脉系统重建似乎更具前景。术后三个月，他以窦性心律、心脏大小正常出院。切除组织的组织学检查显示为无定形血凝块和含铁血黄素细胞的慢性肉芽组织。即使通过显微镜检查也未明确血肿的原因。
