Catheter-Guided Caudal Epidural Blood Patch for Refractory CSF Leak After Multiple Spine Surgeries: A Novel Case Report

This case highlights the feasibility, safety, and clinical efficacy of catheter-guided CEBP performed under fluoroscopic guidance for treating complex, refractory CSF leaks in the early postoperative period. Importantly, it is one of the first reports to demonstrate this approach immediately following failed surgical dural repair, a scenario rarely documented in the literature. By integrating high-resolution MR myelography with precise catheter navigation, targeted therapy can be delivered effectively in anatomically altered spines where conventional techniques are contraindicated. Thus, this case uniquely illustrates how catheter-guided caudal access can serve as a novel, minimally invasive option in the early postoperative setting when direct lumbar access is no longer feasible.
