【摘要】：目的 采用多层螺旋CT肺动脉造影(MSCTPA)评价急性肺栓塞与右心功能参数的相关性,评估急性肺栓塞患者的严重程度。方法 采用非心电门控技术回顾性分析2012年1月-2013年11月间行多层螺旋CT肺动脉造影患者107例,其中肺栓塞组患者57例,对照组50例。采用CT后处理软件测量主肺动脉及胸主动脉内径比值(PA/AO)、右心室相关参数包括四腔心层面左右室短轴内径比(RVD/LVD)及截面积比(RVA/LVA)、横断面左右心室最大短轴内径比值(RV/LV-LD)。对中心死亡、中心存活、周围型肺栓塞及对照组之间右心功能各组参数进行比较。结果 肺栓塞组右心室相关参数RVD/LVD、RV/LV-LD、RVA/LVA均明显大于对照组(P0.05);而PA/AO于两组间无明显差异。肺栓塞组中中心死亡组与中心存活、周围、对照组的RVD/LVD、RV/LV-LD及RVA/LVA三项指标均存在统计学差异(P=0.000);中心存活与周围组的RVD/LVD、RVA/LVA两参数间有差异(P0.05);而周围组与对照组的以上三项指标间均无明显差异(P0.05)。对中心死亡组右心计量指标进行ROC曲线分析得出,RVA/LVA预测APE早期死亡准确性最佳(AUC=0.873),敏感性为100%,特异度为71.2%。结论 多层螺旋CT肺动脉成像不仅能够准确诊断急性肺栓塞,还能客观评价右心室各相关参数,对评估肺动脉栓塞严重程度具有重要意义。
[Abstract]:Objective to evaluate the correlation between acute pulmonary embolism and right ventricular function parameters by multi-slice spiral CT pulmonary angiography (MSCTPA), and to evaluate the severity of acute pulmonary embolism. Methods from January 2012 to November 2013, 107 patients underwent multi-slice spiral CT pulmonary angiography were analyzed by non-ECG gating technique, including 57 patients in pulmonary embolism group and 50 patients in control group. The ratio of main pulmonary artery to thoracic aortic diameter (PA/AO) was measured by CT post-processing software. The related parameters of right ventricle included left and right ventricular short axis ratio (RVD/LVD) and cross section area ratio (RVA/LVA). The ratio of maximum short axis diameter of left and right ventricle (RV/LV-LD). The parameters of right ventricular function were compared between central death, central survival, peripheral pulmonary embolism and control group. Results the RVD/LVD,RV/LV-LD,RVA/LVA of right ventricle in pulmonary embolism group was significantly higher than that in control group (P 0.05), but there was no significant difference in PA/AO between the two groups. There were significant differences in RVD/LVD,RV/LV-LD and RVA/LVA between the central death group and the center in the pulmonary embolism group and around the control group (P 鈮，
