目的探讨急性肺栓塞超声心动图变化特点。方法回顾分析13例明确诊断的急性肺栓塞患者入院时、溶栓治疗7~10d后超声心动图改变,探讨其演变规律。结果入院时1例肺动脉内见血栓,9例肺动脉收缩压升高,9例患者右房、右室增大,9例主肺动脉增宽,3例肺动脉收缩压在正常范围;溶栓治疗7~10d后再次观察:10例肺动脉收缩压升高者压力急剧下降,原9例右房、室增大者大小逐渐恢复,4例右房、室不大患者其内径较入院时也有缩小,原3例肺动脉收缩压正常患者其压力数值也较前缩小。结论超声心动图动态观察对急性肺栓塞诊断、溶栓疗效的判断有重要意义。
Objective To investigate the characteristics of echocardiography in acute pulmonary embolism. Methods Retrospective analysis of 13 cases of acute pulmonary embolism diagnosed at admission, thrombolytic therapy after 7 ~ 10d echocardiography changes to explore its evolution. Results Thrombus was found in one pulmonary artery in admission and systolic pressure in 9 pulmonary arteries was elevated in 9 patients. Right atrium and right ventricle were increased in 9 patients, widened in 9 patients with pulmonary artery and systolic pressure in 3 patients were in normal range. Thrombolytic therapy for 7 ~ 10d again after observation: 10 cases of pulmonary artery systolic pressure decreased sharply, the original 9 cases of right atrium, ventricular enlargement size gradually restored, 4 cases of right atrium, Patients with normal pulmonary artery systolic pressure values also smaller than the previous. Conclusion The dynamic observation of echocardiography is of great significance in the diagnosis of acute pulmonary embolism and thrombolysis.
