Subdural and epi-arachnoid hemorrhage following spinal epidural block requiring hematoma removal: illustrative case.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSpinal epidural block is widely used for pain control. While complications such as CSF leakage or epidural hematoma are occasionally reported, subdural hematoma (SDH) following an epidural block is rare. To the authors' knowledge, a hematoma involving both the subdural and epi-arachnoid spaces has not been previously reported. OBSERVATIONS: A 49-year-old man with a history of chronic back pain developed severe bilateral leg paresthesia 8 days after a routine lumbar epidural block. MRI revealed an SDH extending from T8 to S3, compressing the dorsal spinal canal. Surgical decompression was performed via hemilaminectomy at L2-3 and L5-S1, followed by durotomy and irrigation with a Nelaton catheter. The patient had full symptomatic relief postoperatively and showed complete hematoma resolution within 3 months. LESSONS: Although spinal epidural block is generally considered a safe procedure, rare complications such as SDH can occur. Physicians should maintain a high index of suspicion for such complications in patients presenting without new neurological symptoms after epidural block. When diagnosed with SDH, surgical treatment including laminectomy and irrigation via Nelaton catheter may be necessary to optimize patient outcomes. https://thejns.org/doi/10.3171/CASE25448.
