Percutaneous vertebroplasty (PVP) and balloon kyphoplasty (BKP) are vertebral augmentation techniques, originally designed to treat painful vertebral collapse caused by aggressive hemangiomas. Nowadays, there are many other indications such as osteoporotic vertebral collapse, osteolytic metastases, multiple myeloma, Langerhans cell histiocytosis and burst fractures. Percutaneous vertebroplasty has been introduced by Galibert and Deramond in 1987, and balloon kyphoplasty was executed for first time by Reiley et al. in 1994. More than 38,000 vertebroplasties and 16,000 kyphoplasties are performed yearly in the United States 1. The aim...

We retrospectively reviewed the database of our department for patients who underwent percutaneous balloon kyphoplasty between April, 2010, and June 2014. Only those patients who underwent CT scans or radiographs of the chest after the date of kyphoplasty were selected: 68 patients with 162 levels for balloon kyphoplasty (45 women, 23 men; mean age, 73.19 years (range, 33–97 years)). Each patient underwent at least one computed tomography (CT) scan of treated vertebrae obtained post-operatively for control. We categorized them into 2 groups: patients in the...

Cement pulmonary embolism (CPE) is found in 10/68 patients (14.7%). Mean age, 73.2 years; (range, 33–89 years) and male/female ratio, 1:1. CPE is observed in 8/39 (20.5%) in the group with thoracic CT versus 2/29 (6.8%) with plain radiographs (Fig. 4). The following tables summarize the statistical analysis of relationships between different risk factors and cement pulmonary embolism (table 1-5). Table:1 Relationship between cement pulmonary embolism and presence of cement in the azygos vein. Azygos cement Cement pulmonary embolism TOTAL Positive Negative Present 3 (60%)...

Cement pulmonary embolism (CPE) foundafter balloon kyphoplasty (incidence: 14.7%) in our study. All patients areasymptomatic, mostly because the cement emboli are locatedin the peripheral branches of the pulmonary circulation. Correlation between CPE and cement leakage into azygos and paravertebral plexus of veins is statistically significant.
