Postoperative thoracic hemorrhage after right upper lobectomy with thoracic wall resection during rivaroxaban anticoagulant therapy for deep leg vein thrombosis: A case report

INTRODUCTION Postoperative pulmonary embolism (PE) is the one of the most important complications after thoracic surgery. This complicatin after the surgery is often treated by new anticoaglant drug, such as rivaroxaban, which dose not need to the monitoring of blood coaglation system. We experienced postoperative bleeding case during anticoaglant therapy using rivaroxaban. PRESENTATION OF CASE The patient underwent a right upper lobectomy with lung and chest wall resection for lung cancer. On postoperative day (POD) 10, we started to use rivaroxaban to treat the deep vein thrombosis (DVT). Four days after starting the rivaroxaban treatment, severe surgical site hemorrhage occurred, which led to the need for the infusion of concentrated red cells (CRC). After stopping the rivaroxaban, the thoracic bleeding ceased. Because the event occurred so long after the surgery, and because the bleeding stopped after withdrawal of treatment, we believe that rivaroxaban induced the thoracic bleeding. CONCLUSION Some reports in the field of orthopedics (Turpie et al., 2009) have noted that rivarxaban is effective to prevent postoperative DVT. However, there were few reports that invied the attention to postoperative bleeding be induced by rivarxaban. Thus, we describe this case in order to alert clinicians to the potential bleeding risks associated with the admistration of rivaroxaban postoperatively.
