急性肺栓塞的诊断现状分析及诊断策略研究

目的　分析 10年来我院急性肺栓塞 ( PE)的诊断现状并寻找 PE的有效诊断策略。方法　对10年来确诊 PE的患者资料进行分析统计 ,对近 5个月在急诊科就诊的患者利用临床评价联合肺通气 /灌注扫描和 (或 )螺旋 CT这一新的诊断策略来确诊或排除 PE。所有患者随访 3个月。结果　利用新诊断策略后PE的诊断率、3d确诊率、由肺扫描和 (或 )螺旋 CT确诊的比例均明显提高。应用新诊断策略后 ,需要行肺动脉造影检查的比例和 PE新发生率分别是 2 .8%和 0。结论　临床评价联合肺扫描和 (或 )螺旋 CT是诊断 PE的一项有效诊断策略

Analysis of the status of diagnosis of acute pulmonary embolism and a study of further strategy to improve the diagnostic level

Objective To analyze the present status of diagnosis of pulmonary embolism (PE) by analyzing the clinical data of patients admitted during last 10 years to our hospital, in order to look for a significant diagnostic strategy to improve the diagnostic level. Methods The data of patients diagnosed to have PE in last 10 years were analyzed. In the last 5 months, the patients suspected to have PE were diagnosed by a comprehensive approach including clinical manifestations, lung scan and/or spirals computer tomography(SCT) in our emergency department. Results The diagnostic rate, the final diagnostic rate within 3 days and the diagnostic rate by lung scan or/and SCT were all higher in the last 3 months than ever. The proportions of angiograms and the overall 3month PE risk were 2 8% and 0 Conclusion The comprehensive approach which includes clinical manifestations, lung scan and/or SCT can obviously improve the diagnostic level of PE.
