肺癌术后支气管胸膜瘘致死性大咯血经验（附7例报告）

BACKGROUND AND OBJECTIVE: Massive hemoptysis was a rare but severe postoperative complication of lung cancer. The aim of the present study is to investigate the mechanisms, risk factors, early symptoms, prevention, and treatment options for fatal hemoptysis. METHODS: From April 2007 to May 2011, 1, 737 patients with lung cancer were surgically treated in the West China Hospital of Sichuan University. Twenty patients died during the perioperative period, seven of whom died of massive hemoptysis. These seven cases were analyzed, and their clinical data, as well as related literatures, were reviewed. RESULTS: Massive hemoptysis is the second cause of death after lung cancer surgery. Six patients died directly of massive hemoptysis. One patient underwent secondary surgery because of massive hemoptysis, but eventually died because of lung infection and respiratory failure. Early symptoms of hemorrhage were observed in four cases, and the overall incidence rate of massive hemoptysis was 0.4% (7/1, 737). CONCLUSION: Bronchovascular fistula (BVF) caused by bronchopleural fistula (BPF) is the mechanism for massive hemoptysis. Diabetes is a high risk factor. Early diagnosis and surgical treatment of BPF or BVF can prevent the occurrence of death as a result of massive hemoptysis.
