摘　　要：目的分析256层螺旋CT肺动脉造影(CTPA)对急性肺栓塞(APE)患者右心室功能评价的价值。方法来本院就诊的APE患者,根据CTPA图像及测量相关心血管来分析两组患者的右心室功能参数。分为高危APE组(n=30)和非高危APE组(n=35),共65例,评估死亡风险。结果与非高危APE组比较,高危APE患者组舒张期右室最大径、右室壁厚度、奇静脉宽度、室间隔厚度和肺动脉主干道宽度值均明显增加且差异均有统计学意义(P<0.05或者P<0.01)。相反高危APE患者组的左室最大径明显小于非高危组且差异有统计学意义(P<0.01)。结论利用多层螺旋CT检测右心室功能参数是评估APE严重程度的有效参数,在临床诊断中具有重要的应用价值。Objective To analyze the value of 256-slice spiral CT pulmonary angiography(CTPA)in the evaluation of right ventricular function in patients with acute pulmonary embolism(APE).Methods According to the score of death risk,APE patients who came to our hospital were divided into highrisk APE group(n=30)and non-high-risk APE group(n=35),a total of 65 cases.The right ventricular function parameters of the two groups of patients were analyzed based on CTPA images.Results Compared with the non-high-risk APE group,the maximum right ventricular diameter,right ventricular wall thickness,odd vein width,ventricular septal thickness,and pulmonary artery main tract width values in the high-risk APE patient group were significantly increased and the differences were statistically significant,P<0.05 or P<0.01.On the contrary,the maximum left ventricular diameter of the high-risk APE patient group was significantly smaller than that of the non-high-risk group and the difference was statistically significant,P<0.01.Conclusion Using multi-slice spiral CT to detect the right ventricular function parameters is an effective parameter to evaluate the severity of APE,and it has important application value in clinical diagnosis.
