目的:探讨肺隔离症患者的诊断特点,以进一步提高对本病的认识。方法:回顾分析25例经手术证实的成人肺隔离症患者的临床及影像资料,观察病变部位、形态、密度、边缘及其与周围结构的关系,分析CT血管造影(CTA)成像的特点。结果:25例肺隔离症患者中,病灶位于左肺下叶者16例,位于右肺下叶者9例。患者临床表现为反复咳嗽、咳痰16例,反复咯血5例,其他表现4例。CT表现为“珊瑚状”者11例,肺野内实性肿块者7例,囊性病灶者7例。CTA成像提示,25例肺隔离症患者的供血动脉均发自体动脉,其中22例供血动脉发自胸主动脉,3例发自腹主动脉。结论:为提高肺隔离症的确诊率,CTA成像能直观显示隔离肺组织的血供,可作为诊断肺隔离症的首选方法。
Objective: To investigate the diagnosis of pulmonary sequestration in patients with features to further improve the understanding of the disease. Methods: The clinical and imaging data of 25 patients with confirmed pulmonary sequestration confirmed by surgery were retrospectively analyzed. The relationship between the location of lesions, morphology, density, margins and the surrounding structures was observed and the features of CT angiography (CTA) were analyzed. Results: Among 25 patients with pulmonary sequestration, 16 were located in the left lower lobe and 9 were located in the right lower lobe. Clinical manifestations of patients with repeated cough, sputum in 16 cases, 5 cases of repeated hemoptysis, the other 4 cases. CT showed “coral ” in 11 cases, solid tumors in the lung field in 7 cases, cystic lesions in 7 cases. CTA imaging suggested that the blood supply arteries of 25 cases of pulmonary sequestration were all autologous arteries, of which 22 cases were from the thoracic aorta and 3 from the abdominal aorta. Conclusion: To improve the diagnosis of pulmonary sequestration, CTA imaging can directly display the blood supply of isolated lung tissue, which can be used as the first choice to diagnose pulmonary sequestration.
