摘要
目的探讨儿童肺栓塞(PE)的临床特征、相关危险因素以及影像学特征。方法选取我院47例入院明确诊断肺栓塞患儿的临床及影像学检查资料,分析总结各临床相关危险因素及影像学显示的血栓分布的数量及百分比。结果47例患儿中33例以呼吸道感染症状就诊,危险因素前三位主要为感染、长期卧床和肺外血栓脱落,其中感染类型以支原体感染最多见。47例患儿经肺动脉血管成像(CTPA)确诊肺栓塞。39例肺内可见单发或多发大片实变影,其中肺部实变内血栓12例,肺部实变外血栓14例,病变内外均有血栓13例。47例PE中34例位于右肺下叶,324个血栓中161个位于肺动脉亚段。14例同时伴有其他部位血栓形成。结论儿童肺栓塞多见于感染引起,且以支原体感染最常见。肺栓塞好发于右肺下叶,以亚段受累多见,可累及肺非病变区及肺外血管。
Objective To study the clinical features,risk factors and imaging findings of pulmonary embolism(PE)in children.Methods A retrospective study of the clinical and imaging data was carried out on 47 cases admitted to our hospital from January 2010 to January 2019 with PE,and the number and percentage of the clinically relevant risk factors and imaging distributions of thrombus were analyzed.Results 33 of 47 patients were diagnosed with respiratory symptoms.The top three risk factors were infections,immobilization and extrapulmonary thrombosis,and the most common type of infections was mycoplasma infection.All cases were diagnosed with PE by computed tomography pulmonary angiography(CTPA).Single or multiple areas of large consolidations were found in 39 cases,12 cases of which embolisms occurred in the consolidations,14 cases occurred outside the consolidations,and 13 cases occurred in and outside the consolidations.34 of 47 cases were located in the right lower lobe,and 161 of 324 thrombi were located in the subsegment pulmonary artery.In addition,extrapulmonary thrombus was found in 14 cases.Conclusion PE in children is mostly caused by infection,and the most common infection is mycoplasma.Pulmonary embolism occurs in the lower lobe of the right lung,and is more commonly involved in subsegments.It can involve non-lesioned areas of the lungs and extrapulmonary vessels.
