We report successful surgical management of a 26-year-old man with a ball-shaped thrombus of the tricuspid valve. He had been treated with prednisolone for IgA nephropathy and undergone surgical closure of an isolated ventricular septal defect (VSD). No symptoms, coagulative disorders, or pulmonary embolisms were found. Preoperative echocardiography showed a ball-shaped mass that had originated from the anterior leaflet of the tricuspid valve; it also revealed a small residual VSD. A histological examination revealed the mass to be an organized thrombus with no tumor components. This was a rare case of excision of an organized thrombus of the tricuspid valve. The findings suggest that the thrombus formation may have been associated with the small shunt and/or prednisolone.
我们报告了一例成功手术治疗的26岁男性患者，其患有三尖瓣球形血栓。他曾因IgA肾病接受泼尼松龙治疗，并接受了孤立性室间隔缺损（VSD）的手术闭合。未发现任何症状、凝血障碍或肺栓塞。术前超声心动图显示一个起源于三尖瓣前叶的球形肿块；还发现了一个小的残余VSD。组织学检查显示该肿块为有组织的血栓，无肿瘤成分。这是一例罕见的三尖瓣有组织血栓切除术病例。这些发现提示血栓形成可能与小分流和/或泼尼松龙有关。
