纵隔镜在上腔静脉阻塞综合征诊断中的应用

目的探讨纵隔镜在上腔静脉阻塞综合征（SVCOS）病因诊断中应用的可行性和价值。方法12例上腔静脉阻塞综合征病人，男9例，女3例；年龄16，71岁，平均45．2岁。行颈部纵隔镜检（CM）7例，胸骨旁纵隔镜检（PSM）5例。结果11例获得病理学诊断，阳性率91．7％。其中原发肺癌8例，淋巴瘤3例，未能明确诊断1例；所有病例手术经过均顺利，无并发症和死亡；1例淋巴瘤术后症状加重，化疗后缓解。结论纵隔镜检查对于SVCOS病例同样安全可靠，可作为其他方法不能确诊病例的可靠检查方法。

Diagnostic value of mediastinoscopy in superior vena cava obstruction syndrome

Objective To evaluate the efficacy and value of mediastinoscopy in the diagnosis of superior vena cava obstruction syndrome (SVCOS). Methods 12 patients with SVCOS underwent mediastinoscopy. This group consists of 9 males and 3 females aged 16 to 71 years. 7 cervical mediastinoscopies and 5 parasternal mediastinoscopies were performed. Results In eleven patients, definite pathological diagnosis was obtained, included: primary lung cancer in 8, lymphoma in 3 and invasive thymoma in 1. There were no operative morbidity and mortality. Only in 1 patient with lymphoma the symptom got worse after cervical mediastinoscopy and soon released by chemotherapy. Conclusion Mediastinoscopy is an effective method in the diagnosis of SVCOS.It can be considered as a routine procedure if other methods failed.
