Management of Transforaminal Epidural Steroid Injection with Active CSF Leak

Introduction to Contraindications

The American Medical Association recommends that a transforaminal epidural steroid injection (TFESI) is absolutely contraindicated in a patient with an active CSF leak and should not be performed until the leak is definitively treated 1, 2, 3
Active CSF leaks create intracranial hypotension, and any epidural injection risks worsening the pressure gradient, potentially exacerbating neurological symptoms including orthostatic headache, cranial neuropathies, and hearing loss 1, 2

The primary treatment for an active CSF leak is epidural blood patch (EBP), not steroid injection—introducing steroids into the epidural space does nothing to seal the dural defect and may complicate subsequent blood patching 1, 2, 4
Position the patient supine or in Trendelenburg (5-15 degrees head-down) to reduce CSF pressure gradient and minimize ongoing leakage 2, 3
Maintain strict bed rest for 24-72 hours with adequate hydration to support CSF production 2, 3
If symptoms persist beyond 72 hours of conservative management, perform epidural blood patch (EBP) at or one space below the known site of dural puncture using 15-20 mL of autologous blood with strict aseptic technique 1, 2, 4

Regular follow-up is mandatory to determine need for repeat EBP in cases of persistent or severe CSF leak 1, 2
Watch for cerebral venous thrombosis (occurs in ~2% of intracranial hypotension cases), which presents with sudden change in headache pattern, new focal deficits, or seizures 5, 3
Monitor for subdural hematoma/hygroma, which should be managed conservatively while treating the underlying CSF leak 3

Once the CSF leak is definitively sealed and the patient has achieved symptom resolution, then and only then can consideration be given to TFESI if there is a separate indication for radicular pain management 1, 2
The patient must meet standard criteria for TFESI: MRI-documented nerve root compression correlating with radicular symptoms (pain radiating below the knee), failed conservative therapy for at least 4-6 weeks, and no contraindications 6
Fluoroscopic guidance is mandatory for any subsequent TFESI to ensure proper needle placement and minimize complications 6

Do NOT perform TFESI while an active CSF leak is present—this is not a matter of "individualizing" care; it is an absolute contraindication 2, 3
Do NOT confuse the transforaminal approach for EBP (which delivers blood to seal a ventral leak) with TFESI (which delivers steroids for radicular pain)—these are entirely different procedures with different indications 1
Do NOT delay definitive treatment of the CSF leak by attempting symptomatic management with steroids—the leak must be sealed first 1, 2
