To assess the feasibility and diagnostic performance of lung transthoracic sonography in patients with suspected pulmonary embolism.
In a prospective clinical study we compared sonographic findings of the peripheral lung with various scintigraphic gradings and D-dimer plasma concentrations. One hundred and nineteen consecutive patients with clinical signs of pulmonary embolism were investigated within 24 hours of the onset of symptoms.
Seventy patients with suspected pulmonary embolism (59%) had sonographic lesions, which were echo poor, homogeneous and rounded or wedge-shaped with a hyperechoic reflexion in the centre. Of the patients with high-probability scintigraphic scans 86% had such sonographic lesions as had 79% with intermediate, 64% with low-probability and 33% with normal scintigraphic scans. Of the patients with positive sonographic findings and normal or low-probability scans only a minority (14%) had negative D-dimer tests.
We found a high rate of specific sonographic lesions in patients with suspected pulmonary embolism when investigating the peripheral lung with ultrasound.
评估经胸肺部超声检查在疑似肺栓塞患者中的可行性及诊断性能。
在一项前瞻性临床研究中，我们将外周肺的超声检查结果与各种闪烁扫描分级及D - 二聚体血浆浓度进行了比较。对119例有肺栓塞临床症状的连续患者在症状出现后24小时内进行了检查。
70例疑似肺栓塞患者（59%）有超声病变，表现为低回声、均匀、圆形或楔形，中央有高回声反射。在闪烁扫描高概率的患者中，86%有此类超声病变；中等概率的患者中有79%；低概率的患者中有64%；闪烁扫描正常的患者中有33%。在超声检查结果阳性且扫描正常或低概率的患者中，只有少数（14%）D - 二聚体检测为阴性。
当用超声检查外周肺时，我们发现疑似肺栓塞患者中特异性超声病变的发生率很高。
