[en] Objective: To evaluate percutaneous vertebroplasty (PVP) treatment for benign and malignant vertebral lesions from a technique view. Methods: PVP was performed in 29 consecutive patients with 41 vertebrae involvement, including 23 vertebral metastatic neoplasms in 16 patients, osteoporotic fractures within 10 vertebrae in 7 patient, hemangiomas in 3 patients, and other lesions in 3 patients. PVP procedures were performed under the guidance of CT plus C-arm fluoroscopy or fluoroscopy only. Two to 8 ml of PMMA was injected per vertebra. Results: A techniques success of PVP was obtained in 97.56% (40/41). CR and PR were reached in 65.52% and 31.03% respectively in a follow-up of 2-10 months. No further or new vertebral compression occurred in all patients at the last follow-up. No major complications occurred in this series, except asymptomatic PMMA leak around vertebrae demonstrated by CT in 3 cases. Conclusions: PVP provides significant pain relief in both benign and malignant lesions. Procedure of PVP is safe and uncomplicated when performed under monitoring by C-arm X-ray machine in most cases. It is stressed that a proper use of PMMA is a key factor for PVP procedure
