【摘要】：目的：探讨肺栓塞(PE)患者CT肺动脉造影(CTPA)栓塞指数和心血管参数的相关性，评价肺栓塞(PE)的严重程度对心脏形态的影响及心脏彩超的应用价值。方法：收集通过CT肺动脉造影(CTPA)确诊的、无严重的基础心肺疾病，，符合肺栓塞(PE)诊断患者252例及肺栓塞(PE)治疗3个月后复查患者32例。根据肺动脉内栓子阻塞的程度计算Qanadli栓塞指数(PAOI)，评价栓塞程度与心血管参数相关的关系以及肺栓塞在确诊及治疗后3个月心血管参数的差异。结果：肺栓塞患者Qanadli栓塞指数与心脏彩超所估测的肺动脉压力相关性最好；主干组、叶组、段组的Qanadli栓塞指数与肺动脉压力的相关性逐渐减少；左侧肺叶组Qanadli栓塞指数与肺动脉压力相关性好；≥10肺段的Qanadli栓塞指数与肺动脉压力没有统计学意义；主干组较段组引起右心室前后径、右心房横径的改变更明显；确诊肺栓塞与治疗3个月后Qanadli栓塞指数有差别，心血管参数无差别。结论：肺栓塞的栓塞指数与估测的肺动脉压力具有相关性，临床上可以心脏彩超来估测肺栓塞的栓塞程度。
[Abstract]:Objective: to investigate the correlation between embolization index and cardiovascular parameters in patients with pulmonary embolism (PEE) by CT pulmonary angiography (CTPA). To evaluate the effect of PEI on cardiac morphology and the application value of color Doppler echocardiography (CDFI). Methods: the patients diagnosed by CT pulmonary angiography (CTPA) were collected and there was no serious underlying cardiopulmonary disease. Qanadli embolism index was calculated according to the degree of pulmonary embolism. PAOI). To evaluate the relationship between the degree of embolism and cardiovascular parameters, and the difference of cardiovascular parameters in patients with pulmonary embolism at 3 months after diagnosis and treatment. Qanadli embolism index was best correlated with pulmonary artery pressure estimated by color Doppler echocardiography in patients with pulmonary embolism. The correlation between Qanadli embolism index and pulmonary artery pressure was gradually decreased in the trunk group, lobar group and segmental group. In the left lobe group, the Qanadli embolism index correlated well with pulmonary artery pressure. There was no significant difference between Qanadli embolism index and pulmonary artery pressure in 鈮
