目的　探讨侵及胸廓上口大血管的纵隔肿瘤的外科治疗经验。方法　回顾分析 11例侵及胸廓上口大血管的纵隔肿瘤患者的临床资料 ,全组患者均行纵隔肿瘤切除 ,其中 2例于麻醉诱导前辅以股 -股转流并行体外循环 ,2例辅以颈静脉、股静脉 -股动脉转流并行体外循环。同期行上腔静脉重建 2例 ,成形 2例 ,左无名静脉成形 3例 ,右无名静脉成形 1例 ,无名动脉、左颈总动脉、左锁骨下动脉人造血管置换各 1例。结果　全组病例无手术死亡。术后随访 2～ 7年 ,3例于 2～ 4年后死于癌瘤复发 ,6例无瘤健康生存 ,均未出现血管栓塞。结论　侵及胸廓上口的大血管纵隔肿瘤宜积极手术治疗 ,麻醉诱导前辅以股 -股转流或颈、股 -股转流。同期作血管成形或重建。术后小剂量抗凝治疗 Objective To investigate the surgical treatment of mediastinal tumors invading the thoracic vessels. Methods The clinical data of 11 patients with mediastinal tumor involving the thoracic supercortical vessels were retrospectively analyzed. All the patients underwent mediastinal tumor resection. Two patients were assisted by femoral femoral shunt before cardiopulmonary bypass, two were assisted To jugular vein, femoral vein femoral artery bypass parallel cardiopulmonary bypass. In the same period, 2 cases were reconstructed by superior vena cava, 2 cases were formed, 3 cases were left unnamed vein, 1 case was unnamed vein, 1 case was unnamed artery, left common carotid artery and left subclavian artery. Results All the patients died without surgery. All the patients were followed up for 2 to 7 years. Three patients died of cancer recurrence after 2 to 4 years and 6 patients survived without tumor. No embolization occurred. Conclusions Invasive and thoracic supraclavicular large mediastinal tumors should be actively surgically treated. Before anesthesia induction, the femoral-femoral neck or femoral-femoral neck should be diverted. The same period for angioplasty or reconstruction. Postoperative low-dose anticoagulant therapy
