CT-guided vertebroplasty for painful vertebral fractures

Objetive Describe the technique, results in terms of pain improvement and complications to perform this procedure by computed tomography. Materials and Methods A descriptive observational study of a 108 cases series of percutaneous vertebroplasty guided by computed tomography performed in two university hospitals between May 2007 and May 2017. All procedures were performed with local anesthesia on an outpatient basis, pain was assessed by means of the Visual analogue scale (VAS). Results A total of 125 vertebroplasties were performed. In 87.9% (n = 95) of the patients, the procedure was performed in one vertebral body, in 8.3% (n = 9) and 3.7% (n = 4) of the patientshad two or three vertebrae cemented respectively. The range of pain according to VAS prior to treatment varied between 5 and 10, where 94% (n = 102) of the patients manifested a 10/10 intensity; after treatment, the range of pain varied between 0 to 7 where 98% of the population reported a value less than or equal to 3. Three complications were reported, one pulmonary thromboembolism due to methylmethacrylate, one extravasation in to the Batson plexus and one extravasation of cement to the interdiscal space. Conclusion CT-guided percutaneous vertebroplasty offers an undeniable immediate improvement of pain in patients with fracture of one or more vertebral bodies, with a low rate of complications.
