Fatal pulmonary embolism following shoulder arthroplasty: a case report

INTRODUCTION: Fatal pulmonary embolism following a shoulder joint replacement is a rare event. The exact prevalence of shoulder arthroplasties is not clear. Unlike hip and knee joint replacements where some form of thromboprophylaxis is routinely prescribed, no such guidelines and practice exist for shoulder replacements. Other case reports have confirmed fatal and non-fatal pulmonary embolisms following shoulder replacements, but particular risk factors were identifiable in those patients. CASE PRESENTATION: We report the case of a 73-year-old Caucasian woman with fatal pulmonary embolism secondary to a calf deep vein thrombosis following a shoulder joint replacement procedure. The patient was otherwise healthy; there were no other risk factors directly contributing to deep vein thrombosis and pulmonary embolism except for a body mass index of 34. Post-mortem examination confirmed that the patient had a thrombus in the calf and a pulmonary embolus. CONCLUSIONS: Fatal deep vein thrombosis and pulmonary embolism can occur following shoulder joint replacements in otherwise normal patients. A high degree of suspicion should therefore be maintained in susceptible individuals. Thromboprophylaxis needs careful consideration in shoulder replacements in susceptible individuals.
