A left-sided L5-S1 lumbar disc herniation operation was performed on a
36-year-old woman in 1987. After a 6-year period, the same patient ca
me back to the clinic with the problem of severe sciatic pain on the s
ame side as before. Upon diagnosis, it was seen that the left S1 radix
was compressed with a piece of free autofat graft in the foramen, whi
ch was used in the first operation. As far as the writers are informed
, this is the first report about a later complication of epidural auto
fat graft in lumbar spine disc surgery.
