【摘要】 目的:探讨经胸超声心动图在急性肺栓塞诊断与治疗中的价值。方法:对经临床综合诊断(包括核素肺灌注扫描或CT血管造影)确诊为急性肺栓塞的患者46例进行经胸超声心动图检查。结果:超声心动图直接检出右室内血栓1例,主肺动脉及左、右肺动脉分支血栓5例。右心异常改变者26例(包括超声直接检出血栓的6例),其中右房室增大19例;右室收缩功能减退21例;室间隔左移、左室短轴切面室间隔向左室膨突呈"D"型改变1例;室间隔运动幅度减低13例;主肺动脉及右肺动脉增宽22例;三尖瓣中量以上返流23例;肺动脉收缩压增高23例,范围在33～81mmHg(62.87±23.46mmHg),治疗后肺动脉压明显下降,范围在21～52mmHg(34.26±13.52mmHg)。结论:动态经胸超声检查是急诊诊断和治疗急性肺栓塞中重要无创影像诊断手段。更多还原

【Abstract】 Objective:To assess the value of transthoracic echocardiography (TTE) in the diagnosis and treatment of acute pulmonary embolism.Methods: Forty-six patients with acute pulmonary embolism underwent TTE. Results: Thrombus within right ventricle(RV) and main pulmonary artery(MPA) was detected in 6 patients,right atrium (RA) and RV enlargement was found in 19 patients, right ventricular hypokinesis was found in 21 patients, hypokinesis of interventricular septum(IVS) was detected in 13 patients, MPA and right pulmonary arterial(RPA) dilation was found in 22 patients ,marked tricuspid regurgitation was detected in 23 patients,pulmonary hypertension was found in 23 patients.Conclusion:Systemic and dynamic TTE plays important roles in the diagnosis and treatmemt of acute pulmonary embolism.更多还原
