The purpose of this study is to analyze the frequency of other diagnoses and findings in patients that were diagnosed with or not diagnosed with PE following the CTPA in the ED and to analyze the relationship between diagnosis and D-dimer. INSTRUMENT AND METHOD: This study involves all patients that presented to the ED that underwent CTPA with the prediagnosis of PE. The items considered in this study were their reason for presenting to the ED and pretest clinical risks for PE, D-dimer, and CTPA results.
Of the 696 cases, the most common cause was shortness of breath (59.3%). The CTPA showed that 145 (20.83%) patients were suffering from PE. Among the remaining cases, 464 (66.66%) patients had pathological findings other than PE and 87 (12.5%) patients were reported as normal. The most common pathological results other than PE found in CTPA were atelectasis in 244 (39.9%) and ground glass in 165 (23.7%), as well as nonpulmonary results in 70 (10.05%) patients. The differences in D-dimer results of patients diagnosed with PE, patients diagnosed with another pathology, and patients with normal CTPA results were statistically significant (P < 0.001).
CTPA scanning, performed on the basis of assessment scoring, helps in discovering other fatal pathologies in addition to PE.
本研究的目的是分析在急诊科接受CTPA检查后被诊断或未被诊断为肺栓塞（PE）的患者中其他诊断和检查结果的频率，并分析诊断与D-二聚体之间的关系。
本研究纳入了所有因疑似PE而在急诊科接受CTPA检查的患者。本研究考虑的项目包括他们到急诊科就诊的原因、PE的检查前临床风险、D-二聚体以及CTPA结果。
在696例病例中，最常见的原因是呼吸急促（59.3%）。CTPA显示145例（20.83%）患者患有PE。在其余病例中，464例（66.66%）患者有除PE以外的病理检查结果，87例（12.5%）患者报告为正常。CTPA中除PE外最常见的病理结果是肺不张244例（39.9%）、磨玻璃影165例（23.7%），以及70例（10.05%）患者有非肺部结果。诊断为PE的患者、诊断为其他病理情况的患者以及CTPA结果正常的患者之间D-二聚体结果的差异具有统计学意义（P < 0.001）。
基于评估评分进行的CTPA扫描，除了能发现PE外，还有助于发现其他致命性病变。
