CT-Guided Epidural Blood Patch for Postoperative Lumbar CSF Leak: 100% Immediate Relief in 9-Patient Series

In a retrospective 9-patient series, CT-guided epidural blood patch provided immediate symptomatic relief in all (100%) and sustained short-term resolution in 8/9 (88.9%) for postoperative lumbar CSF leak. No complications.

• Retrospective, single-center study of 9 patients with symptomatic CSF leak after decompressive lumbar laminectomy, all treated with CT-guided epidural blood patch.
• Among 6 patients with long-term follow-up (median 812 days, range 141-1471), all maintained complete symptom resolution.
• Small retrospective series without a control group; results require validation in larger prospective studies.
