Intrapulmonary Activated Factor VII for Hemoptysis Complicating Pulmonary Thromboendarterectomy

Abstract

Massive hemoptysis represents a life-threatening disorder that has numerous different causes. The development of recombinant factor concentrates has allowed for novel treatments in this emergency setting. This report describes a patient with chronic thromboembolic pulmonary hypertension who underwent pulmonary thromboendarterectomy. The postoperative course was complicated by massive hemoptysis resulting in severe hypoxemia that required extracorporeal membrane oxygenation and multiple daily blood transfusions. After failure of conservative and interventional approaches, recombinant factor VII was administered by bronchial isolation. After treatment, the patient's hemoptysis dramatically resolved, with eventual hospital discharge and excellent function at follow-up. This case presents the use of intrapulmonary activated factor VII to control massive hemoptysis.
