| 摘 要： | 目的 探讨CT肺动脉栓塞指数(PAOI)半定量评价急性肺栓塞(APE)右心功能的价值。方法 回顾性分析经CT肺血管成像(CTPA)确诊的、无严重基础心肺疾病的APE患者117例,依据肺动脉内栓子阻塞的部位及程度计算PAOI。根据PAOI<30%、30%~50%和＞50%将APE患者分为轻、中和重度三组,分析各组的右心功能参数的差异。结果 入选患者中,轻度组65例,中度组32例,重度组20例。轻度与中度组比较,差异有统计学意义的指标有RVd、LVd、RVd/LVd、RVs、LVs、RVs/LVs、MPA、LPA、IVSD、IVCR;轻度组与重度组比较,差异有统计学意义的指标有RVd、LVd、RVd/LVd、RVs、LVs、RVs/LVs、SVC、MPA、RPA、LPA、IVSD、IVCR、AZR;中度组与重度组比较,差异有统计学意义的指标有LVd、RVd/LVd、RVs/LVs。结论 APE患者的PAOI可以反映右心功能情况,并有助于及时确认APE的病情程度。 |

| Abstract: | Objective To semi-quantitatively evaluate the right ventricular function in patients with acute pulmonary embolism(APE) with CT pulmonary artery obstruction index(PAOI).Methods Totally 117 patients with APE diagnosed with spiral computed tomography were retrospectively analyzed and selected as being non-severe of underlying cardiopulmonary disease.PAOI was estimated on the basis of the degree of obstruction and location of the thrombus on CT imaging according to the method described by Mastora etc.The patie... |
