Autologous Platelet-rich Plasma Versus Whole Blood for Epidural Patch in Spontaneous Intracranial Hypotension
22 maj 2026 uppdaterad av: Fang Luo, Beijing Tiantan Hospital
Autologous Platelet-rich Plasma Versus Whole Blood for Epidural Patch in Spontaneous Intracranial Hypotension: A Multi-center, Prospective, Randomized Controlled Trial
Spontaneous intracranial hypotension (SIH) is a condition characterized by refractory orthostatic headache, mostly due to leaks of cerebrospinal fluid (CSF).
Epidural patch with autologous platelet-rich plasma (PRP), which contains numerous growth factors and cytokines, has been reported as a new and promising alternative for current standard whole blood patching.
However, there is no study comparing the efficacy and safety of the two approaches.
In this study, we aimed to provide data concerning the outcomes of PRP patching versus conventional whole blood patching for treatment of refractory SIH cases failing in conservative therapy.

Experimentell: PRP Patch (PP)
|
Autologous PRP was prepared with the 2-stage centrifugation method and mixed with iohexol contrast.
We chose two separate sites for epidural access.
A standard epidural puncture was conducted under the guidance of CT.
The PRP mixture was titrated slowly into the epidural space and must be stopped immediately to patient's perception of backache or irradiating pain.
A strict bed stay for 48 h was prescribed in supine position postoperatively.

Aktiv komparator: Whole blood patch (WP)
|
Autologous whole blood was prepared and mixed with iohexol contrast.
We chose two separate sites for epidural access.
A standard epidural puncture was conducted under the guidance of CT.
The whole blood mixture was titrated slowly into the epidural space and must be stopped immediately to patient's perception of backache or irradiating pain.
A strict bed stay for 48 h was prescribed in supine position postoperatively.

|
|
The good response rate of patients with SIH.
Tidsram: At 48 hours, 2 weeks, 3 and 6 months after first epidural patch

Good response was defined as a headache reduction of at least 50%, with improvement of orthostatic component post-procedurally.
|
At 48 hours, 2 weeks, 3 and 6 months after first epidural patch
|
|
The failure rate in each group.
Tidsram: At 6 months after first epidural patch
|
Failure was defined as a persistent or worsening symptom with less than 50% of headache reduction within 72 hour post-procedurally.
|
At 6 months after first epidural patch
|
|
The recurrence rate in each group.
Tidsram: At 6 months after first epidural patch

Recurrence was defined as fresh onset of orthostatic headache in completely relieved patients beyond the 72-hour mark.
|
At 6 months after first epidural patch
|
|
Patients'quality of life
Tidsram: At 3 and 6 months after first epidural patch
|
Patients'quality of life was evaluated by Headache Impact Test (HIT-6), with six item scores of headache-related disability divided into 36-49 (little or no impact), 50-55 (some impact), 56-59 (substantial impact), and ≥60 (severe impact).
