【摘要】：目的探寻右心房黏液瘤的超声特点,评价超声心动图对右心房黏液瘤的诊断价值。方法回顾分析20例右心房黏液瘤的超声表现,总结右心房黏液瘤的超声心动图特点。结果右心房黏液瘤的临床症状主要有胸闷、气短、下肢浮肿及晕厥等。超声测量瘤体大小为3.11 cm×2.90 cm~7.44 cm×4.52 cm,形态为类圆形或分叶状。瘤蒂附着于房间隔者占75%,附着于右心房游离壁者占25%。瘤蒂平均宽度为(1.62±0.30)cm,宽度大于1 cm者占80%。部分黏液瘤内部可见钙化和囊状无回声区。右心房内血流阻塞占70%,三尖瓣狭窄占50%,肺高压者占10%。结论超声心动图可以准确评价右心房黏液瘤瘤体特点及继发心内结构和血流动力学改变,为临床作出及时、准确诊断提供重要依据。
[Abstract]:Objective to explore the ultrasonic characteristics of right atrial myxoma and evaluate the diagnostic value of echocardiography for right atrial myxoma. Methods the ultrasonic features of 20 cases of right atrial myxoma were reviewed and analyzed, and the echocardiographic characteristics of right atrial myxoma were summarized. The main clinical symptoms of right atrial myxoma were chest tightness, shortness of breath, swelling of lower limbs and syncope. The size of the tumor was 3.11 cm x 2.90 cm~7.44 cm x 4.52 cm, and the morphology was round or lobulated. The tumor pedicle attached to the atrial septum accounted for 75%. The average width of the 25%. pedicle attached to the right atrium was (1.62 + 0.30) cm, and the width was greater than 1 cm in the inner part of the 80%. part of the myxoma. The blood flow in the right atrium was visible. Obstruction accounted for 70%, three apical stenosis accounted for 50%. 10%. conclusion echocardiography in patients with pulmonary hypertension could accurately evaluate the characteristics of right atrial myxoma and secondary cardiac structure and hemodynamic changes, providing an important basis for timely and accurate diagnosis.
