肺隔离症尸检1例报告并文献复习

Pulmonary sequestration：case report and review of the literature

目的对1例经尸检证实的肺隔离症病例分析，并进行文献复习。方法对1例经尸检证实为肺隔离症患者的临床及病理资料进行分析，结合文献讨论本病279例的临床特点、诊断方法和治疗措施。结果叶内型219例（78．5％），叶外型37例（13．3％）。未报道23例（8．2％）。临床多有反复肺部感染。误诊率72．8％。选择性动脉造影或增强CT确诊率100％。结论肺隔离症者应尽早行增强CT或血管造影确诊和手术。

Objective To highlight the characteristics of pulmonary sequestration（PS） with combination of practical experience and review of literature. Methods One patient with PS confirmed by biopsy was described and the relevant literatures o（ 279 cases were reviewed. Results PS can be divided into two types： intratobar type and extralobar type. The percentage of intralobar type is about 78.5 %, intralobar type is 13.3 %, other unreported is 8.2 %. Clinically, PS was often combined by repeated pulmonary infection. The mis-diagnose rate is 72.8 %. Etrograde arteriography or enhanced CT scan could find the abnormal artery, from which we can make correct diagnosis. The diagnose rate is 100 %. Conclusion For patients with above clinical and X-ray symptoms, PS should be consid- ered. Enhanced CT or retropgrade arteriography examination should be done as soon as possible. Timely diagnosis and surgery treatment are important for curing this kind of disease.
