Objective. To analyze cases of pulmonary cement embolism and to determine possible causes of the complication. Material and Methods.A heterogeneous group of 49 patients was retrospectively analyzed. Vertebroplasty was prescribed to the patients for restoration of vertebral support ability after osteoporotic compression fractures and hemangiomas, and as an auxiliary manipulation for transpedicular fixation of the osteoporotic spine. Thoracic computed tomography was performed and pulmonary cement embolism was revealed in the early or late postoperative periods.Results. Pulmonary cement embolism was revealed in 7 (14 %) patients, two of them presented with massive pulmonary cement embolism. In one case it was caused by excessive injection of cement, and in the other -by anomalous anastomosis. In one case, the vertebroplasty was cancelled taking into account the results of venospodilography. Conclusion
To analyze the causes of interspinous dynamic stabilization failures in patients with lumbar spine degenerative disorders. Material and Methods. Retrospective analysis of 155 cases of interspinous dynamic stabilization using DIAM device was performed. Twenty three cases with poor results were selected for detailed analysis. Results. It was revealed that reoperation rate for this method was 15 %, but only 8 % of failures were related to the technology itself. Main complications associated with interspinous stabilization devices included fracture and erosion of the spinous processes, destruction and migration of implants, and infection. In nine cases poor results were associated with surgeon's mistake in planning or performing of the procedure. Conclusion. Decision making for performing interspinous stabilization should be based on evaluation of indications and factors, which adversely affect its prognosis. These factors include elderly age of a patient, decreased bone quality, narrow and short interspinous gap, significant deformation and hypertrophy of the articular processes, significant slope of the spinous process, and essential amount of the planned bone decompression.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
