Study DesignWe report a case of pulmonary embolism of polymethylmethacrylate material after percutaneous vertebroplasty.ObjectiveTo describe a severe vertebroplasty complication, the pulmonary embolism, which proved to be fatal in a patient with many chronic disabilities.Summary Of Background DataUntil 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.MethodsThis 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.ResultsThe course of the operation was complicated by pulmonary infection, and the patient ultimately succumbed to infection/respiratory failure.ConclusionThe 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.
