Use of Extracorporeal Membrane Oxygenation for Lung Cancer-Related Massive Hemoptysis: A Case Report and Literature Review.

Massive hemoptysis is a common, life-threatening complication of lung cancer, and asphyxiation due to major airway obstruction is the leading cause of death. Extracorporeal membrane oxygenation (ECMO) can temporarily replace pulmonary gas exchange, stabilize acute respiratory failure, and provide a window for definitive therapy. This case report describes a patient with squamous cell carcinoma who developed catastrophic hemoptysis and successfully underwent right pneumonectomy under venovenous ECMO support, followed by uneventful recovery and discharge. In addition, a focused literature review was conducted to examine the role and optimal timing of ECMO as an adjunct to surgery for lung cancer-related massive hemoptysis, offering practical insights for clinicians managing this critical condition.
