The Surgical Management of Holospinal Epidural Abscess: A Case Report and Review on Catheter-Based Irrigation Techniques

Holospinal epidural abscess (HEA) is an extremely rare spinal infection involving the entire spine and is infrequently reported in the literature. Cases with evidence of spinal cord compression and consequent neurological deficit are typically managed with prompt surgical drainage and broad-spectrum antibiotics. Surgical intervention is often challenging because this condition is inherently associated with poor prognosis and serious complications, including death. During the surgical evacuation of the abscess, catheter-based irrigation must be adequately performed. In the majority of reported cases, the extent of the advancement of the epidural catheter is blindly assessed by the operating surgeon, increasing the risk of residual collections and subsequent persistent infection. Herein, we report a rare case of HEA that was successfully treated with surgical evacuation and skip laminectomies. We also describe a catheter-based technique that facilitates adequate irrigation, thereby ensuring the complete drainage of HEA in obscured perispinal areas, as well as the decompression of the spinal cord. Postoperative neurological examination exhibited marked improvement in motor function (compared with a baseline of complete quadriparesis), indicating the successful decompression of the spinal cord and neurological improvement.
