Nebulized Tranexamic Acid Therapy for Hemoptysis Associated with Submassive Pulmonary Embolism

Abstract

Hemoptysis and pulmonary embolism (PE) are life-Threatening pulmonary emergencies that, when present together, create a therapeutic conundrum. We present an illustrative case of a 65-year-old man with unprovoked submassive PE and moderate hemoptysis due to pulmonary infarction. Hemoptysis precluded systemic anticoagulation. Failing a conservative management strategy, we administered nebulized tranexamic acid. After four doses of nebulized tranexamic acid 500 mg, 6 hours apart, hemoptysis had ceased. Systemic anticoagulation with intravenous heparin was then successfully commenced 12 hours after the last episode of hemoptysis. The patient was weaned off high-flow nasal oxygen therapy over the..
