title: [Analysis of the complication and prevention on treatment of osteoporotic vertebral compressive fractures by percutaneous vertebroplasty (PVP)].
abstract: OBJECTIVE
  To analyze the reasons of the complications,and the measures taken for the prevention and treatment by percutaneous vertebroplasty (PVP) for osteoporotic thoracolumbars vertebral compressive fractures.
  
  
  METHODS
  From May 2004 to June 2008, 204 patients with 286 diseased vertebrae underwent PVP under the guidance of C-arm fluoroscopy, and 56 patients with complications included 18 males, 38 females, ranging in age from 58 to 93 years, with an average of 72 years. The condition of leakage of bone cement and complications was observed.
  
  
  RESULTS
  The complications related to the leakage of PMMA found in 60 vertebrae in 49 cases: vertebral canal in 5 cases, intervertebral foramina in 3 cases, soft tissue besides vertebrae in 20 cases,intervertebral discs in 15 cases, venous plexus besides vertebrae in 6 cases. The complications no related to the leakage of PMMA found in 7 cases: the nerve roots injuried in 3 cases; the pain of the patient worsened temporarily in 2 cases; the blood pressure of the patient descent temporarily in 2 cases.
  
  
  CONCLUSIONS
  The main reasons of complications are no-integrated of the compressived vertebrae,unstandard skills of injecting,unsuitable opportunity and quantity of injecting PMMA, unsufficient monitoring of C-arm fluoroscopy, the toxicity of PMMA. The measures of prevention and treatment is strict indication, standard skills of injecting, sufficient monitoring of C-arm fluoroscopy, suitable opportunity and quantity of injecting PMMA, electrocardio-monitoring in operation.
