Abstract:
Objective To explore the methods and clinical application of percutaneous pediculoplasty in the treatment of vertebral pedicular osteolytic metastases.Methods Percutaneous pediculoplasty was performed in 18 patients with (23 Vertebral pedicles ) osteolytic metastases,3 cases localized in thoracic vertebral pedicles and 15 cases in lumbar vertebral pedicles,and two vertebral pedicles involved in 5 cases . Under Multislice helical CT guidance ,2.5～5ml of polymethylmethacrylate ( PMMA ) mixture (ratio of polymer,moner,ultrafluid iodinated oil was 20g:10ml:3ml) was injected into pathologic pedicles in step by step after successful puncture using 11-13G needles. All cases had been followed for 1～18 months.Results All cases were successful punctured. Pain relieved in all cases after percutaneous pediculoplasty.7 cases had cement leakage,among them,cement leaked into tumor tissue in 5 cases(2 cases with leakage into intervertebral foremen),nerve radicular pain occurred in one case,the pain disappeared 3 days later after intravenous mannitol and lower dose dexamethasone drips;the cement leaked into vertebral canal a little without clinical symptom in one case.Conclusion CT-guided percutaneous pediculoplasty is a minimally effective and safe method for osteolytic vertebral pedicular metastases in treatment of pain and enhancement of spinal stability.
