Percutaneous vertebroplasty (PVP) is increasingly used to treat osteoporotic vertebral fractures, myeloma and osteolytic vertebral metastases. The purpose of this study was to measure the absorbed radiation exposure dose and time during PVP and to assess the possibility of deterministic radiation effects to the operator and patient. The radiation dose and time measure by three pain physicians performed consecutive procedures using the twenty case PVP. Patient’s dosimeter placed at the anteroposterior(AP) side was treatment of the vertebra body located in the upper level 2-3 and lateral(LAT) side was flank proximal to C-arm tube of back. Operator’s dosimeter placed at the apron outside of upper sternum (thyroid), left chest, lower extremity and apron inside of left chest. Results: Radiation exposure times were 3.6±0.71 min. Measurements on the Patient radiation dose were AP 121.4±48.1 μSv, LAT side 614.7±177.1 μSv. Operator radiation dose were outside of the lead apron upper sternum 33.7±7.3 μSv, outside of the lead apron chest 49.2±15.0 μSv, outside of the lead apron lower extremity 12.8±3.8 μSv and inside of the lead apron chest 4.2±1.4 μSv. To escape from the danger of radiation first long distance from the c-arm tube second exposure time reduced second lead apron used fluoroscopy during PVP is more safety patient and operation from the radiation exposure.
