Abstract:
Objective To explore the safety and effectiveness of percutaneous vertebrophasty(PVP)in the treatment of the metastatic tumor involved axis.Methods Ten patients(8 male,2 female)with osteolytic metastases involved axis were treated with PVPs.The anterolateral approach with fluoroscopy guidance was selected in 9 cases,while the posterolateral approach with CT guidance was selected in 1 case.Results Successful unilateral-paracentesis for PVP were achieved in all patients without intervention related complications such as bleeding and symptomatic polymethylmethacrylate(PMMA)leakage.CT scan taken following PVP showed that over 70% of the osteolytic metastatic area was well filled with PMMA in all cases.Varying degrees of pain relief were observed(CR in 7 cases,PR in 3 cases)within 7 days.All patients could support their heads without brackets.During a 3 to 24 months follow up after the procedures,No aggravated pain was found in the group.Two patients died in 4 months,3 Patients died in 8 to 11 months 4 patients died in 13 to 15 months,and 1 patient still was alive after 24 months.Conclusion Anterolateral or posterolateral approach to Aixs in PVP is safe and effective in treating osteolytic metastatic tumors.
