 Abstract
- Purpose: Recent advances in imaging techniques have significantly enhanced the diagnosis of spontaneous intracranial hypotension (SIH). However, these developments have been reported mostly in Europe and the United States. This study aimed to evaluate the availability and utilization of diagnostic and treatment modalities for SIH in Asia, through a survey of regional headache specialists.
Methods
A literature search was conducted using PubMed, and members of the Asian Regional Consortium for Headache were contacted. Participants completed a two-step survey evaluating the availability, accessibility, and frequency of SIH diagnostic and treatment methods in their countries and institutions. Descriptive statistics were used to analyze the data.
Results
Twenty physicians from eight countries completed both rounds of the survey. Lumbar puncture, brain magnetic resonance imaging (MRI), and spinal MRI are widely available across Asia, but real-time imaging techniques—such as dynamic computed tomography myelography and digital subtraction myelography—that precisely localize cerebrospinal fluid leaks are less accessible. Blind or semi-targeted epidural blood patches (EBPs) are available at most centers, but are easily accessible in only about half of cases. Surgical interventions are rarely available.
Conclusion
Most diagnostic methods for SIH are available in Asia, despite some regional disparities. The utilization of EBP and surgical interventions remains somewhat limited. This highlights the need for greater awareness and standardization of diagnostic methods in Asia.
