Clinical efficacy of CT-guided epidural autogenous blood patch in treatment of spontaneous refractory intracranial hypotension headache / 中国介入影像与治疗学

ABSTRACT

Objective: To observe the efficacy and safety of CT-guided epidural blood patch (EBP) in treatment of spontaneous refractory intracranial hypotension headache. Methods: Clinical and imaging data of 12 patients with spontaneous intracranial hypotension headache treated with CT-guided EBP were retrospectively analyzed, and visual analogue scale (VAS) and complications were calculated before and after procedures. Results: A total of 12 patients received 19 CT-guided EBP therapy, among which 7 patients received secondary EBP therapy. Five patients had postoperatively localized neck pain unrelated to body position, and then healed spontaneously within 1 week. No serious complication occurred. VAS of all patients at each time point after operation was lower than that before operation (all P<0.01), and the clinical symptoms relieved or disappeared after operation. No recurrence was detected during 3 months' follow-up. Conclusion: CT-guided EBP is effective and safe in treatment of spontaneous refractory intracranial hypotension headache.
