摘要
目的 对比急性非高危肺栓塞患者不同栓塞类型的临床、影像及风险分层特征分析。方法 收集在本院通过CTPA确诊的非高危急性肺栓塞患者进行回顾性分析,对比不同类型急性肺栓塞患者临床以及影像学特征,并探索肺栓塞类型与早期风险分层之间的关系。结果 277例非高危急性肺栓塞患者中,鞍型MPA栓塞34例,约占12.27%,不同类型栓塞患者在性别、年龄、有无下肢静脉血栓及合并症上比较差异无统计学意义(P>0.05);而在影像学特征(PAOI、肺动脉直径、肺/主动脉比值、RV/LV比值)中发现,鞍状肺栓塞与非鞍状肺栓塞、非MPA栓塞中存在显著差异,(P<0.05);不同类型的急性非高危肺栓塞患者危险分层,在sPESI评分中,非鞍型MPA栓塞和非MFA栓塞患者多被划分为中-低危组,而在Bova评分中,Boval级患者的比例较高。结论不同类型急性非高危肺栓塞患者严重程度存在差异,鞍状肺栓塞和非鞍状肺栓塞患者较非MPA患者的肺动脉高压及右心室功能障碍出现的频率更高,肺栓塞影像学指标再结合患者临床及实验室检查,有助于早期识别患者危险度,为患者的治疗及预后提供更大帮助。
Objective Comparing the clinical,imaging and risk stratification characteristics of different embolism types in patients with acute and non-high-risk pulmonary embolism.Methods Clinical data of 277 patients with non-high risk pulmonary embolism diagnosed by CTPA were collected for retrospective analysis,to compare clinical and radiographic characteristics of patients with different types of acute pulmonary embolism,and to explore the relationship between pulmonary embolism type and early risk stratification.Results Of the 277 patients with non-high critical pulmonary embolism were divided into saddle MPA(34 cases),For about 12.27%.There was no significant difference between different types of embolism in gender,age,lower extremity venous thrombosis and comorbidities,Significant were found between the different type of pulmonary embolism in the imaging features(PAOI,pulmonary artery diameter,pulmonary/aortic ratio,RV/LV ratio);risk stratification of acute non�high-risk pulmonary embolism,patients with non-saddle MPA and non-MPA embolization were mostly classified into medium-low risk groups,whereas Bova grade I had a higher proportion in Bova scores.Conclusion Different types of acute non-high-risk pulmonary embolism patients with the severity of disease,saddle pulmonary embolism and non-saddle pulmonary embolism patients than MPA patients with pulmonary hypertension and right ventricular dysfunction frequency,pulmonary embolism imaging index combined with clinical and laboratory examination,help to early identification of patient risk,provide greater help for the treatment and prognosis.
