BackgroundPercutaneous endoscopic lumbar diskectomy (PELD) has evolved over the last decades and has become an effective treatment for soft disk herniations. However, while its use increases, newer complications have been discovered.Case DescriptionWe present the unique case of a woman who underwent PELD/foraminotomy to treat right-side foraminal disk herniations on L4-5 and L5-S1 in the same procedure. Ten days after surgery, the patient developed fever and severe low back pain radiated down her right leg. Magnetic resonance imaging showed a right pseudomeningocele arising from L4-5 and a nerve root herniated through the dural sac at the same lumbar segment. Blood cultures and fluid culture obtained from pseudomeningocele drainage depicted infection. Specific antibiotics were administrated, direct dura repair under the microscope was performed, and the patient improved symptomatically.ConclusionsPELD combined with foraminotomy is a relatively new and skill-demanding surgery which is indicated only in cases where foraminal disk herniation is combined with foraminal stenosis. This surgical strategy requires experience by the endoscopic surgeon to prevent procedure-related complications. Although rare, these complications can lead to increased morbidity.Copyright © 2018 Elsevier Inc. All rights reserved.
