原发性心脏脂肪瘤的病理学及超声心动图学特征研究

目的：探讨原发性心脏脂肪瘤的病理学及超声心动图学特征及其临床特点。方法：对21例原发性心脏脂肪瘤患者的超声心动图学、病理学及临床资料进行回顾性分析。结果：①21例患者的病理学结果示有20例（20/21,95.2%）脂肪瘤位于房间隔,2例（2/21,9.5%）起源于多部位,有1例（1/21,4.8%）位于左心室后壁心外膜侧。②13例患者曾行术前或常规经胸超声心动图检查,结果只有3例（3/13,23.1%）发现异常。③21例病人都没有出现明显与肿瘤相关的临床症状。结论：原发性心脏脂肪瘤因缺乏特异性临床表现而诊断困难,超声心动图只能发现少部分心脏脂肪瘤。

Clinical Echocardiographic and Pathologic Features of Primary Cardiac Lipoma

Objective：To investigate the clinical,pathological and echocardiagraphic features of primary cardiac lipomas.Method：The pathological and echocardiography data of 21 patients with cardiac lipomas were reviewed retrospectively.Result：①There were twenty patients（20/21,95.2%） whose tumors orginated from the interatrial septum,and two patients（2/21,9.5%）from miscellous parts.Only one case （1/21,4.8%）the tumor was detected in the posterior surface of ventricle during the operation.②Thirteen patients were performed echocardiography before getting the pathological data.But only three cases（3/13 23.1%,）were detected abnormalities in right atrium.③No symptoms were significantly related with tumors of the 21 patients.Conclusion：The diagnosis of primary cardiac lipomas is sometimes difficult because of their nonspecific clinical presentation.The diagnostic sensitivity of echocardiography is limited in lipoma patients.
