目的探讨超声检查对肺动脉栓塞的诊断价值。方法对25例临床综合诊断的肺动脉栓塞患者行经胸超声心动图和双下肢深静脉超声检查,对其中22例进行治疗后复查。结果超声心动图发现3例肺动脉血栓直接征象,22例右心系统形态改变,22例肺动脉高压。周围血管超声检查出下肢深静脉血栓8例。22例治疗后复查超声心动图示肺动脉内栓子消失,肺动脉收缩压恢复正常或明显下降,右房室内径恢复正常或明显减少。结论超声检查是一快速、便捷、无创的肺动脉栓塞诊断方法,对该病的疗效评估、预后判断也有重要作用。
Objective To investigate the diagnostic value of ultrasonography in pulmonary embolism. Methods Twenty-five patients with pulmonary embolism diagnosed underwent transthoracic echocardiography and deep venous double-lower-extremity ultrasonography. Twenty-two of them were reviewed after treatment. Results Echocardiography showed direct pulmonary thromboembolism in 3 cases, morphological changes of right heart in 22 cases and pulmonary hypertension in 22 cases. Peripheral vascular ultrasound detected 8 cases of deep vein thrombosis. Twenty-two patients underwent echocardiography after treatment. The pulmonary embolism disappeared, the pulmonary systolic pressure returned to normal or decreased significantly, and the right atrioventricular diameter returned to normal or significantly decreased. Conclusion Ultrasonography is a rapid, convenient and noninvasive method for the diagnosis of pulmonary embolism. It also plays an important role in evaluating the curative effect and prognosis of the disease.
