Thread-like Bone Cement in the Right-side Heart and Pulmonary Arteries Causing Diffuse Pulmonary Embolism as a Late...

Pulmonary embolism (PE) is usually associated with deep vein thrombosis (DVT) in the lower extremities. However, foreign bodies in the pulmonary arteries can rarely cause PE without evidence of DVT. In this report, we present a case of diffuse PE associated with a migrated thread-like structure of the right-side heart and pulmonary arteries in a 70 year-old woman. The patient underwent several episodes of percutaneous vertebroplasty (PV) to treat compression fractures. The thread-like foreign bodies were identified as the bone cement injected during the previous PV procedures. We present this case study to emphasise that clinicians should consider the possibility of PE as a late complication, especially those with a history of PV.
