目的探讨肺动脉栓塞急诊行CT三维重建在急性肺栓塞诊断中的价值。方法对2012年1月1日至2013年12月31日之间就诊于某院急诊科临床疑似肺栓塞的71例患者行急诊多层螺旋CT扫描血管成像术了解有无影像学确诊肺栓塞依据。结果所有病例均获得满意图像,影像学确诊患者65例(91.5%),表现为肺动脉充盈缺损56例(86.2%),完全闭塞9例(13.8%),65例CT确诊肺动脉栓塞患者,经多因素相关性分析提示肺动脉栓塞与年龄无显著相关性,95%CI,1.044(0.741-1.607),P=0.84;与患者有静脉血栓性疾病(P=0.003)、肿瘤基础疾病(P=0.045)、近期行手术或创伤(P=0)有显著相关性。结论对于疑似急性肺栓塞患者急诊行CT扫描血管成像术可有效、快速确诊肺动脉栓塞。
Objective To investigate the value of three-dimensional computed tomography reconstruction of pulmonary embolism in the diagnosis of acute pulmonary embolism. Methods From January 1, 2012 to December 31, 2013, 71 patients with clinically suspected pulmonary embolism in a hospital emergency department underwent emergency multislice CT scan angiography to find out whether there was any evidence of pulmonary embolism . Results All the cases were satisfactorily imaged and 65 cases (91.5%) were diagnosed by imaging. There were 56 cases (86.2%) with pulmonary insufficiency, 9 cases (13.8%) with complete occlusion and 65 cases with pulmonary embolism confirmed by CT. Correlation analysis showed that there was no significant correlation between pulmonary embolism and age (95% CI 1.044, 0.741-1.607, P = 0.84), and patients with venous thrombosis (P = 0.003), tumor underlying disease There was a significant correlation between surgery and trauma (P = 0) in the near future. Conclusions Emergency CT scan angiography is an effective and rapid diagnosis of pulmonary embolism in patients with suspected acute pulmonary embolism.
