  "abstract": "Background: Paravertebral tuberculous abscess is a clinically important complication of spinal tuberculosis and may require image-guided drainage before definitive surgical management. Contrast-enhanced ultrasound (CEUS) may improve visualization of abscess vascularity and internal architecture, but its clinical value in catheter drainage for paravertebral tuberculous abscess remains insufficiently defined.\n\nMethods: This retrospective historical-control study included 67 patients with lumbar spinal tuberculosis complicated by paravertebral tuberculous abscess who underwent ultrasound-guided catheter drainage at Hangzhou Red Cross Hospital between January 2010 and January 2025. Patients were divided into a conventional ultrasound-guided drainage group (Group A, n = 39) and a CEUS-assisted drainage group (Group B, n = 28). Baseline characteristics, postoperative recovery parameters, inflammatory markers, pain scores, clinical outcomes, and drainage-related complications were compared between groups.\n\nResults: Postprocedural bleeding occurred after 5 of 41 drainage procedures (12.20%) in the conventional ultrasound-guided group and after 0 of 31 procedures (0.00%) in the CEUS-assisted group. Catheter occlusion and pericatheter purulent discharge rates did not differ between groups. Operative time, length of hospital stay, intraoperative blood loss, inflammatory markers, pain scores, cure rate, and recurrence rate also did not differ between groups.\n\nConclusions: In this retrospective historical cohort, CEUS-assisted drainage was associated with fewer recorded postprocedural bleeding events and provided additional anatomical information for procedural planning.",
