急性肺血栓栓塞症的超声心动图诊断价值
【摘要】 目的 探讨超声心动图在急性肺血栓栓塞症诊断中的应用价值。 方法 回顾性分析52例临床综合检查而确诊的急性肺栓塞患者超声心动图结果。结果 超声心动图发现16例肺动脉内血栓直接征象, 右心系统扩大41例、肺动脉增宽37例、室间隔运动异常28例、三尖瓣反流41例、肺动脉收缩压增高37例。超声心动图检查大致正常者7例。 结论 超声心动图在诊断肺动脉栓塞中具有重要的临床意义。

【Abstract】 Objective To evaluate the diagnostic value of echocardiography in acute pulmonary thromboembolism. Methods Retrospective analysis was performed for echocardiography in 52 patients with pulmonary thromboembolism. Results Thrombus within left or right pulmonary artery were detected in 16 patients, typical right heart enlargement was showed in 41 patients, pulmonary artery dilation and pulmonary hypertension were showed in 37patients,motion abnormality in interventricular septum was found in 28 patients, tricuspid regurgitation was showed in 41 patients, pulmonary hypertension was founded in 37 cases, normal echocardiogram in 7 cases. Conclusion It is significant to diagnose pulmonary embolism with echocardiography that helps to enhance the accuracy of the diagnosis.

既往认为肺栓塞属少见病,但近年来的流行病学调查认为是多发病。在心血管疾病中,深静脉血栓形成和肺栓塞的发病率仅次于冠心病和高血压,居第3位;而肺栓塞的病死率占全部疾病死亡原因的第3位, 仅次于肿瘤和心肌梗死[1]。由于肺栓塞的临床症状多样化和不具备特异性,以及对其缺乏诊断意识和诊断技术条件限制等原因,目前肺栓塞的临床漏诊率和误诊率均较高。随着影像技术的进展, 肺栓塞的诊断水平明显提高, 超声心动图以其无创、便...
