ABSTRACT

Objective To evaluate the clinical effect of lumbar intervertebral disc herniation (LIDH) by CT-guided precise injection around nerve root and in epidural cavity. Methods One hundred and eight patients of LIDH were treated by CT-guided precise injection around nerve root and in epidural cavity, and followed-up after 1, 3 and 6 months. Visual analogue score (VAS) for pain was used to evaluate the efficacy before and after treatment. Results In 108 cases, there were 83 patients (76.9%) with good result whose improvement of VAS was greater than or equal 50% after treatment 1, 3 and 6 months. There were 19 patients (17.6%) with fair result whose improvement of VAS was less than 50% after treatment 1, 3 and 6 months. There were 6 patients (5.6%) with invalid result whose improvement of VAS was unobvious after treatment 1, 3 and 6 months. Conclusion CT-guided therapy of LIDH by precise injection around nerve root and in epidural cavity is safe, accurate, effective, minimally aggressive technique and worth being practiced clinically.
