The procedure problems and solution of CT-guided percutaneous biopsy of spinal diseases

Objective: To discuss the procedural problems and solution correlatively of CT-guided percutaneous biopsy of spinal diseases, with simultaneous evaluation of the safety and clinical application. Methods: Sixty-eight cases with spinal diseases were taken CT-guided percutaneous biopsy under local anesthesia and CT guidance, including 9 in cervical spine, 19 in thoracic spine, 28 in lumbar spine and 12 in sacral spine. The program of carrying out the procedure was decided according to the site, approach route of the lesion with the destination of sampling, under CT guidance. Results: The successful rate of needle puncture was 100%(68/68)with diagnostic accuracy of 92.6%(63/68), and false-negative rate of 7.4%(5/ 68), together with complications rate of 5.9% (4/68). Conclusions: CT-guided vertebral biopsy is safe, reliable, less complication, high accuracy and together with clear demonstration of the position of puncture needle and the complex anatomic structures nearby, providing basic information for further clinical treatment and worthy to be recommended.
