[Preliminary clinical application of percutaneous vertebroplasty].
OBJECTIVE
To investigate the clinical application of percutaneous vertebroplasty (PVP).


METHODS
PVP was performed in 21 cases of 37 vertebral lesions,including 14 osteoporotic compression fractures, 6 metastases, 1 hemangioma,and 17 lesions in thoracic vertebra and 20 in lumbar. The procedures of PVP were as follows: The needle was inserted via percutaneous transpedicular approach or percutaneous posterolateral vertebral approach; the needle tip was placed at the junction of the anterior located the one third of the vertebral body; intraosseous venography was performed; and last bone cement was injected at 2-10 mL. The technical success rate, clinical efficacy and complications were observed after the procedure. Results The procedure was successful in 18 cases with 31 lesions,and the success rate according to the number of cases and vertebral lesions was 85.7% (18/21) and 83.8% (31/37), respectively. After the procedure, the numbers of complete remission, partial remission, mild remission and no remission were 10, 5, 2 and 1, respectively; and the total effective rate was 94.4% (17/18). Progressive compression did not occur. Three patients had transient neuropathy and recovered after physiotherapy. Other complications were insignificant; no severe complications occurred. Conclusion PVP is an effective and micro-traumatic treatment for patients with benign and malignant lesions in vertebral bodies.
