The authors report a case in which a free fat graft, placed at the operative site after hemilaminectomy for lumbar disc herniation, was forced into the spinal canal by action of the paraspinal muscles and behaved as a symptomatic space-occupying lesion. The patient recovered satisfactorily after the graft was removed. The pathogenetic mechanism is discussed and guidelines to avoid this complication are outlined.
作者报告了一例病例，在腰椎间盘突出症半椎板切除术后将游离脂肪移植置于手术部位，该脂肪移植因椎旁肌的作用被挤入椎管，并表现为有症状的占位性病变。取出移植组织后患者恢复良好。文中讨论了发病机制并概述了避免该并发症的指南。
