Abstract

Background Pulmonary embolism (PE) is an acute, significant, and life-threatening condition. Transthoracic ultrasound (TUS) is one of the noninvasive diagnostic modalities that has been presented for detection of numerous chest disorders as well as PE. Objectives The goal of this work was to estimate the accuracy, sensitivity, and specificity of bedside TUS in PE detection. Patients and methods Fifty patients with moderate-to-high clinical suspicion of PE were examined by TUS. Diagnosis of PE depended on clinical suspicion and was confirmed by computed tomography pulmonary angiography. Results Most of the lesions related to PE and detected by US examination were on the right side (60%) and posterior lower lobe (70%) with predominance of A profile. Sensitivity, specificity, accuracy, negative, and positive predictive values of TUS in diagnosis of PE were 93.3, 65, 82, 86.7, and 80%, respectively. Conclusion TUS is an important diagnostic tool as a noninvasive bedside test in detecting PE principally for critically ill or unmoving patients with high sensitivity and moderate specificity.
经胸超声对肺栓塞的诊断价值
肺栓塞(PE)是一种急性、严重且危及生命的疾病。经胸超声(TUS)是一种非侵入性诊断方式,已被提出用于检测许多胸部疾病以及PE。目的本研究的目的是评估床边TUS在PE检测中的准确性、敏感性和特异性。患者与方法对50例临床中高怀疑PE的患者进行超声心动图检查。PE的诊断依赖于临床怀疑,并通过计算机断层肺血管造影证实。结果超声检查发现的PE相关病变多位于右侧(60%)和后下叶(70%),以A型为主。TUS诊断PE的敏感性、特异性、准确性、阴性预测值和阳性预测值分别为93.3、65、82、86.7和80%。结论超声心动图是一种重要的无创床边检查方法,主要用于危重患者或不能活动的患者,具有较高的敏感性和中等的特异性。
