Autologous Platelet-rich Plasma Versus Whole Blood for Epidural Patch in Spontaneous Intracranial Hypotension
Sponsor: Beijing Tiantan Hospital
Summary
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.

PRP Patch group
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.
Whole Blood Patch Group
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.
