摘　　要：目的研究多层螺旋CT心血管参数评价急性肺栓塞(APE)严重性的价值。方法 APE患者分为严重APE组(28例)和非严重APE组(47例)2组。根据CT肺动脉内栓子阻塞部位和程度计算CT阻塞指数;测量右室短轴最大径、左室短轴最大径、右室与左室短轴最大径比、右室壁厚、主肺动脉直径及上腔静脉直径;观察室间隔是否左突。评价严重APE组和非严重APE组之间的CT心血管参数的差异是否有统计学意义。结果严重APE组与非严重组的CT心血管参数有统计学差异(P<0.05)的指标包括:阻塞指数、右室短轴最大径、左室短轴最大径、右室与左室短轴最大径比、右室壁厚、主肺动脉直径及室间隔位置。结论综合分析APE患者的CT心血管参数变化,有助于判断APE患者的严重性。Objective To study the value of CT cardiovascular parameters on evaluating the severity of the patients with acute pulmonary embolism（APE）.Methods The patients with APE were divided into two groups：severe APE（n=28）and non-severe APE（n=47）.CT obstruction index was calculated according to the location and degree of clots in the pulmonary arteries.Cardiovascular parameters were measured including right ventricular（RV）and left ventricular（LV）maximal short-axis,RV maximal short axis to LV maximal short axis（RV/LV）ratio,RV wall thickness,main pulmonary artery and superior vena cava diameter.The position of the interventricular septum was observed.The results were analyzed.Results Comparision of CT cardiovascular parameters between patients with severe and non-severe pulmonary embolism showed significant differences（P〈0.05）in RV maximal short-axis,LV maximal short-axis,RV/LV ratio,RV wall thickness,main pulmonary artery diameter,leftward bowing of the interventricular septum.Conclusion CT cardiovascular parameters is helpful for evaluating the severity of the patients with APE.
