摘要
目的 探讨肺癌合并上腔静脉综合征（SVCS）的CT表现为早期诊断、紧急处理提供依据.方法 收集天津肿瘤医院自2001年7月至2010年3月病理确诊肺癌合并上腔静脉综合征50例,回顾性分析肺癌解剖部位、大体类型与其导致SVCS方式的CT表现之间的关系;回顾性分析上腔静脉梗阻程度与侧枝循环的建立与开放、胸壁水肿之间的关系,并分别做四格表或R×C表Х^2检验.结果 肺癌引起SVCS的方式包括直接侵犯7例,淋巴结转移16例,两者并存27例.不同部位不同大体类型肺癌引起SVCS的方式差异具有统计学意义（Х^2=30.012,P＜0.05）.肺癌引起SVCS后的继发改变包括侧枝循环建立开放14例,胸壁水肿12例,两者均有15例,两者均无9例.肺癌引起SVCS时上腔静脉梗阻程度不同,胸部侧枝循环和胸壁水肿CT显示率不同（Х^2=12.881,P＜0.05）.结论 CT增强检查可以全面诊断肺癌合并SVCS,能为该病的急诊处理提供依据.
Objective To investigate the role of CT in the diagnois of superior vena cava syndrome secondary to pulmonary carcinoma. Method Fifty patients with pulmonary carcinoma resulting in SVCS were confirmed by pathological examinations. Relationship between anatomical distribution and gross type of pulmonary carcinoma and modes of pulmonary carcinoma resulting in SVCS were analyzed retrospectively and statistically. Correlation among obstructive degree of SVC, opening of collateral pathway and swelling of chest wall was analyzed retrospectively and statistically. Results For modes of pulmonary carcinoma resulting in SVCS, direct invasion of pulmonary carcinoma was 7 patients, metastasis of lymph node was 16 patients and both of the two was 27 patients.Modes of pulmonary carcinoma resulting in SVCS were different for different gross types of pulmonary carcinoma in different pulmonary lobes （ Х^2 = 30.012,P 〈 0.05）. On CT appearances of secondary lesions, cases of simple constitution and opening of collateral pathway, simple swelling of chest wall, both of the two and neither of the two were 14 patients, 12 cases, 15 patients and 9 patients in order on CT. With SVC obstruction at different extent,constitution and opening of collateral pathway and swelling of chest wall were different （ Х^2= 12.881, P 〈 0.05）.Conclusions SVCS resulted from pulmonary carcinoma can be diagnosed by contrast enhanced CT.
