Clinical Characteristics Of Pleural Effusion In Patients With Pulmonary Embolism

Background:Pulmonary embolism is a common disease.There are a lot of studies about Pulmonary embolism.But,there are few studies on pulmonary embolism complicated with pleural effusion.It is not clear whether there are differences of the clinical characteristics between pulmonary embolism complicated with pleural effusion and that without pleural effusion.Objective : To study the clinical characteristics of pulmonary embolism patients complicated with pleural effusion.To reduce the missed diagnosis rate and misdiagnosis rate of pulmonary embolism paitents complicated with pleural effusion.Methods:According to the results of CTPA,the patients are divided into two groups: pleural effusion group(effusion group)and non-pleural effusion group(control group).Clinical characteristics are compared between the two groups.Results:Pleural effusion caused by pulmonary embolism is usually small and bilateral.Chest pain is more common among pulmonaryembolism patients with pleural effusion(P < 0.05).Syncope is more common among pulmonary embolism patients without pleural effusion(P <0.05).The level of CRP in pulmonary embolism patients with pleural effusion is higher than that in the control group(P < 0.05).Chest pain was an independent predictor of pleural effusion caused by pulmonary embolism(OR 0.254,95% CI 0.070 / 0.918).Conclusions : Pleural effusion caused by pulmonary embolism is usually small and bilateral.Chest pain is more common among pulmonary embolism patients with pleural effusion,while syncope is more common among pulmonary embolism patients without pleural effusion.The level of CRP in pulmonary embolism patients with pleural effusion is higher than that in patients without pleural effusion.Chest pain is an independent predictor of pleural effusion caused by pulmonary embolism.
