摘　　要：目的评价CT肺血管成像（CTPA）右心功能不全（RVD）征象对急性肺栓塞患者临床病情严重性的提示价值。方法回顾性分析93例CTPA确诊的肺栓塞，以CT横切位图像右心室／左心室最大横径比〉1（RVd／LVa〉1）作为右心功能不全的诊断标准，分析并比较RVD及非RVD患者的症状和体征差异。结果在93例患者中，43例诊断为RVD，50例诊断为非RVD。RVD患者中，晕厥、发绀、颈静脉充盈和P2亢进的发生率明显高于非RVD患者，有显著性差异。结论通过CTPA评价RVD有助于早期确认肺栓塞患者的病情严重性。Objective To investigate the value of evaluation of right ventricular dysfunction（RVD） with CT pulmonary angiogra） phy（CTPA） for assessment of the clinical significance of patients with acute pulmonary embolism（PE）. Methods Ninty-three cases with PE proved by CTPA were retrospectively reviewed. Using the right/left ventricular maximal diameter ratio 〉1 on CTPA as the diagnostic standard for RVD. The symptoms and signs between patients with and without RVD were compared and analyzed. Resuits In the 93 cases, 43 were diagnosed as with RVD and 50 without RVD. The incidence of the syncope , cyanosis , filling of jugular vein and P2 in patients with RVD were significantly higher than that in patients without RVD. Conclusion The sign of RVD evaluated on CTPA is helpful to ascertain the clinical significance of PE.
