ABSTRACT
STUDY DESIGN: We report a case of pulmonary embolism of polymethylmethacrylate material after percutaneous vertebroplasty. OBJECTIVE: To describe a severe vertebroplasty complication, the pulmonary embolism, which proved to be fatal in a patient with many chronic disabilities. SUMMARY OF BACKGROUND DATA: Until 2007, the literature noted that the risk of embolism of polymethylmethacrylate after a percutaneous vertebroplasty counted a small number of pulmonary cement embolism and a smaller number of fatal consequences. The most recent research revealed that the risk of a pulmonary cement embolism ranges from 3.5% to 23% for osteoporotic compression fractures. METHODS: This study is a case report of an 80-year-old patient with multiple medical comorbid factors, chronic obstructive pulmonary disease, mild renal failure, osteoporosis, and hepatic cirrhosis. Symptoms of pulmonary embolism developed 1 month after a percutaneous vertebroplasty. An echocardiography report suggested that the cement infiltrated the right atrium and the right pulmonary artery, and this was confirmed by a computed tomographic scan. As the therapy with oxygen and low-molecular-weight heparin failed to solve the thrombus, the patient required a surgical tricuspid annuloplasty and the extirpation of the right atrial and right pulmonary masses. RESULTS: The course of the operation was complicated by pulmonary infection, and the patient ultimately succumbed to infection/respiratory failure. CONCLUSION: The presence of intravascular/intracardiac foreign bodies is underreported in literature, but it is quite common in clinical practice. We need to discuss the choice of some non-risk-free interventions such as vertebroplasty in older patients already affected by multiple main disabilities.
