Yoon, Lee, Lee, Lee, and Kang: Comparison of the Efficacy of Epidural Autologous Blood Patch in the Treatment of Spontaneous Intracranial Hypotension and Post-Dural Puncture Headache

Abstract

Purpose

To evaluate and compare the effectiveness of fluoroscopy-guided epidural blood patch (EBP) in patients with post-dural puncture headache (PDPH) and spontaneous intracranial hypotension (SIH).

Materials and Methods

Between August 2012 and September 2013, 16 patients (12 with PDPH, 4 with SIH; 5 males, 11 females; age range 19-58 years, mean age 32.8 years) who underwent EBP in the Department of Radiology were included in this study. Pain relief within three days after EBP was evaluated based on medical record and classified on a 3-level scale: complete relief; incomplete relief; and failure. Recurrence is defined as aggravated postural headache after three days. We evaluated and compared treatment outcome between PDPH and SIH, using Fisher's exact test (considered as significant when p < 0.05).

Results

In 12 PDPH patients, the EBP provided complete relief in 5 patients (41.7%), and incomplete relief in 7 patients (58.3%). In 4 SIH patients, the EBP provided complete relief in 1 patient (25%), and incomplete relief in 3 patients (75%). There was no significant difference (p = 0.511) of pain relief rate between PDPH and SIH. There was recurrence in 5 patients with PDPH and 1 patient with SIH. Five PDPH patients were retreated by EBP with incomplete relief.

Conclusion

Fluoroscopy-guided EBP provides effective treatment of postural headache for both SIH and PDPH patients.
