肺隔离症的诊断与外科治疗

目的 总结肺隔离症(pulmonary sequestration, PS)的临床特征、诊断及外科手术治疗经验,以期提高对PS的诊疗水平. 方法 1993年8月至2007年2月我科共收治21例PS患者,其中男8例,女13例;年龄13～70岁.术前分别行胸部X线、CT、CT血管造影术(CTA)、磁共振成像(MRI)和正电子发射体层摄影CT(PET-CT)等检查;叶外型肺隔离症(ELS)行隔离肺切除术,叶内型肺隔离症(ILS)行肺叶切除术;共行左肺下叶切除术10例,右肺下叶切除术3例,左隔离肺切除术4例,右隔离肺切除术3例,行左全肺切除术1例. 结果 本组术后病理均明确诊断为PS,其中ELS 7例,ILS 14例;术前临床诊断为PS 7例.18例术中见有明显来自体循环的异常供血血管,其中单纯来源于胸主动脉11例,单纯来源于腹主动脉6例,另1例有2条异常血管,分别来源于胸、腹主动脉.异常血管直径为0.2～1.1 cm(平均0.7 cm),术中予双重结扎和缝扎;另有明显引流静脉3例,均经下肺静脉回流入左心房,予双重结扎.围手术期无死亡及并发症的发生.术后门诊随访20例,失访1例,随访率95.2%(20/21),随访至2009年1月,随访时间12～67个月.随访期间1例行全肺切除术患者术后2年因肺癌肝转移而死亡,其余患者情况良好. 结论 PS较为少见,临床症状无特异性,易误诊或漏诊;诊断方法主要为胸部X线、CT、MRI检查及选择性动脉造影;一旦确诊,大多主张外科手术治疗.

The Diagnosis and Surgical Treatment of Pulmonary Sequestration

Objective To summarize the clinical experiences and surgical treatment of pulmonary sequestration(PS) in order to improve the diagnosis and treatment of PS.Methods Between August 1993 and February 2007,our department enrolled 21 PS patients,8 male patients and 13 female patients,with the age ranging from 13 to 70 years old.The patients were examined by chest radiography,computerized tomography(CT),computerized tomography angiography(CTA),magnetic resonance imaging(MRI),position emission tomography-CT(PET-CT...
