肺隔离症影像诊断与介入治疗的临床研究

Imaging Diagnosis and Interventional Therapy of Pulmonary Sequestration

目的探讨肺隔离症的影像诊断特征与介入治疗方法,为临床对本病的诊治提供参考资料。方法回顾分析2例肺隔离症的临床影像和介入治疗资料,并复习国内外肺隔离症的诊断和介入治疗相关文献。结果 2例患者均采用Vascular Plug行介入治疗,皆成功封堵异常供血动脉。X线平片主要表现为囊状、团状或不规则高密度影及支气管扩张样改变,胸部电子计算机断层扫描(computed tomography,CT)可发现部分患者异常供血动脉,CT血管造影(computed tomography angiography,CTA)诊断价值更高,而数字减影血管造影(digital subtraction angiography,DSA)可以清楚显示异常供血动脉的起源、直径、走向、形态和数量,可指导治疗。结论主动脉DSA是确诊肺隔离症的"金标准",介入治疗肺隔离症创伤小且安全有效。

Objective To discuss the imaging manifestations and interventional therapy of pulmonary sequestration,and improve clinical diagnosis and treatment of pulmonary sequestration.Methods The clinical imaging and interventional therapy data of 2 pulmonary sequestration patients were retrospectively analyzed,and the relevant references about pulmonary sequestration were reviewed.Results The interventional therapy with Vascular Plug was performed successfully,and the abnormal blood supply artery was blocked.Chest X-ray showed cystic,lump or irregular high density shadow and bronchiectasis.Chest computed tomography（CT）showed abnormal blood supply artery in some patients.Computed tomography angiography（CTA）had good diagnostic value,but digital subtraction angiography（DSA）could guide interventional therapy directly through clearly demonstrating the origin,diameter,orientation,shape and amount of abnormal blood supply artery.Conclusion DSA is the ＂golden standard＂ in identifying pulmonary sequestration.Interventional therapy is less invasive,safe and effective for pulmonary sequestration.
