目的探讨超声心动图鉴别心脏少见肿瘤良、恶性的临床意义。方法随机对29例心脏肿瘤患者进行经胸及经食管超声心动图检查,观测肿块形态、内部回声、边界、包膜及血流分布情况。结果29例心脏肿瘤中23例经手术病理证实,良性8例,恶性15例,6例转移癌未获病理诊断。超声正确诊断18例,未定性诊断9例,误诊2例。结论超声心动图能对心脏少见肿瘤进行初步定性诊断和鉴别诊断,是术前唯一能向临床提供较为可靠依据的无创性检查手段。
Objective To investigate the clinical significance of echocardiography in differentiating benign and malignant cardiac tumors. Methods Twenty-nine patients with cardiac tumors underwent transthoracic and transesophageal echocardiography. The morphology, internal echo, boundary, envelope and blood flow were observed. Results Twenty-nine cases of cardiac tumors were confirmed by operation and pathology, 8 cases were benign, 15 cases were malignant, and 6 cases were not diagnosed by pathology. 18 cases were correctly diagnosed by ultrasound, 9 cases were diagnosed by unidentification and 2 cases were misdiagnosed. Conclusions Echocardiography can make preliminary qualitative diagnosis and differential diagnosis of rare cardiac tumors. It is the only noninvasive examination method that can provide more reliable evidence to the clinic before operation.
