【摘要】：目的:探讨CTA和DSA血管参数在肺栓塞治疗对肺动脉高压影响中的评估价值。方法:回顾性分析22例肺动脉栓塞患者的临床资料,治疗前肺动脉收缩压(PASP)为(52.77±13.30)mm Hg,治疗后PASP为(20.91±2.78)mm Hg。分别在CTA及DSA图像上测量主肺动脉、左肺动脉、右肺动脉及升主动脉直径,计算主肺动脉直径与升主动脉直径比值(r PA),使用t检验评价治疗前后所测血管参数的变化情况,利用ROC曲线分析并比较CTA及DSA评估肺动脉高压改变的价值。结果:除升主动脉直径以外的其他血管参数在治疗前后均有统计学差异。主肺动脉直径和r PA在CTA评估的ROC曲线下面积(AUC)分别为0.824、0.841,前者的敏感度及特异度均为81.8%,后者分别为81.8%、77.3%;主肺动脉直径和r PA在DSA评估中的AUC值分别为0.874、0.932,两者的敏感度及特异度均为86.4%。结论:CTA和DSA均有助于临床评估肺动脉高压变化情况,DSA的评估价值、敏感性和特异性均高于CTA。
[Abstract]:Objective: to evaluate the effect of CTA and DSA on pulmonary hypertension. Methods: the clinical data of 22 patients with pulmonary embolism were retrospectively analyzed. Before treatment, the systolic pressure of pulmonary artery was 52.77 卤13.30mm Hg, and the PASP was 20.91 卤2.78mm Hg. The diameter of main pulmonary artery, left pulmonary artery, right pulmonary artery and ascending aorta were measured on CTA and DSA images, respectively. The ratio of main pulmonary artery diameter to ascending aorta diameter was calculated. T test was used to evaluate the changes of blood vessel parameters before and after treatment. ROC curve was used to analyze and compare the value of CTA and DSA in evaluating the changes of pulmonary hypertension. Results: the parameters of pulmonary artery except ascending aorta diameter were significantly different before and after treatment. The diameter of main pulmonary artery and rPA were evaluated in CTA. The area under the ROC curve was 0.824 卤0.841, the sensitivity and specificity of the former were 81.8 and 77.3, respectively, and the diameter of pulmonary artery and rPA in DSA were 0.874 卤0.932, respectively. The sensitivity and specificity of both were 86.44.Conclusion the diameter of pulmonary artery and rPA in DSA evaluation are both 86.42.Conclusion the diameter of pulmonary artery and rPA in DSA evaluation are 0.874 卤0.932, and the sensitivity and specificity of them are 86.42.Conclusion the diameter of pulmonary artery and rPA in DSA evaluation are 0.874 卤0.932. All of them are helpful for clinical evaluation of pulmonary hypertension and the value of DSA in evaluating pulmonary hypertension. The sensitivity and specificity were higher than those of CTAs.
