Purpose:
To evaluate the effectiveness of fluoroscopy guided transpedicular abscess infusion and drainage in thoracic-lumbar spondylitis with prevertebral abscess.
Methods:
We retrospectively reviewed 14 patients with infectious spondylitis with prevertebral abscesses from January 2019 to December 2022. All patients underwent fluoroscopy guided transpedicular abscess infusion and drainage. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), visual analog scale (VAS), Macnab criteria, and magnetic resonance imaging (MRI) were compared before and after the operation to evaluate clinical outcomes.
Results:
Among the 14 patients with prevertebral abscesses, 64.29% (9/14) involved the lumbar spine and 35.71% (5/14) involved the thoracic spine. The ESR, CRP, and VAS scores decreased from 87.34 ± 9.21, 93.01 ± 11.17, and 8.38 ± 0.97 preoperatively to 12.35 ± 1.61, 8.52 ± 1.19, and 2.02 ± 0.64 at the final follow-up, respectively. MRI at the final follow-up showed the disappearance of the prevertebral abscess compared with that in the preoperative group (66.95 ± 12.63 mm in diameter). Ten patients achieved an "excellent" outcome, while the remaining four patients obtained a "good" outcome according to the Macnab criteria.
Conclusion:
Fluoroscopy guided transpedicular abscess infusion and drainage is a safe and minimally invasive procedure for the management of thoracic-lumbar spondylitis with a prevertebral abscess.
