BackgroundNo formalized surgical treatment strategy exists for a thoracic epidural abscess. Although endoscopic approaches have been described for the treatment of spinal infections, this is the first report of an endoscopic transforaminal approach for the drainage of a thoracic/lumbar epidural abscess with placement of indwelling abscess drain. We present a novel use of a known endoscopic approach and describe a minimally invasive surgical option for ventrally located thoracic epidural abscesses.Case DescriptionA patient with ventrally located T5-L5 epidural abscess with cord compression was taken for endoscopic transforaminal drainage at the right T9-10 level. A drain was left in the abscess cavity and tunneled subcutaneously for continued postoperative drainage. Immediate postoperative radiographic results showed significant reduction in the abscess size. The patient tolerated the procedure well with return to neurologic baseline.ConclusionsEndoscopic transforaminal drainage of ventrally located thoracic epidural abscess is a safe procedure that may be an option for patients with a purulent-filled abscess. This procedure should be considered an option to avoid more invasive procedures that would require decompression and possibly instrumented fusion.Published by Elsevier Inc.
