Abstract
To evaluate the effectiveness of fluoroscopy guided transpedicular abscess infusion and drainage in thoracic-lumbar spondylitis with prevertebral abscess. 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. 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. 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.
