Cement pulmonary embolism after percutaneous vertebroplasty in a patient with cushing's syndrome: A case report

Abstract Background Vertebroplasty is a procedure most commonly used for vertebral compression fractures. Although it is a relatively safe procedure, complications have been reported. Cement embolism is seen in 2.1%–26% of patients after percutaneous vertebroplasty. Case presentation a 38-year-old male who was diagnosed with cushing's syndrome, underwent percutaneous vertebroplasty for his thoracic osteoporotic compression fractures. 24-hours following vertebroplasty, he presented to emergency department with acute-onset dyspnea and chest pain. Chest radiography showed an opaque linear lesion in left pulmonary artery which was suggestive of cement embolism. Pulmonary spiral CT-scan further confirmed the diagnosis. The patient's symptoms improved over time, and warfarin was started with close cardiopulmonary assessments for indicators of cement embolus removal. Conclusion in patients with pulmonary cement embolism, conservative treatment may be recommended rather than a surgical removal except when the obstruction is extensive enough to cause hemodynamic changes. Given that all the related studies have suggested that pulmonary thromboembolism can occur as a complication due to bone cement leakage, discovering new cement alternatives and/or injection devices, seems beneficial.
