Spontaneous hemothorax following thrombolytic and anticoagulant therapy for massive pulmonary embolism

Massive spontaneous hemothorax following combined thrombolytic and anticoagulant therapy for pulmonary embolism (PE) is a rare event that is little documented in the literature. Here, we describe a rare case of spontaneous hemothorax in a 23-year-old woman with underlying systemic lupus erythematosus following combined administration of tissue plasminogen activator and low-molecular-weight heparin for massive PE. This report of our successful treatment of this case by video-assisted thoracoscopic thoracotomy demonstrates that although the occurrence is rare, massive hemothorax following anticoagulant and/or thrombolytic therapy for PE should be suspected if patients experience chest pain, dyspnea, or signs of anemia, and follow-up physical examination and hemogram should be performed to facilitate diagnosis of this life-threatening complication.
