ABSTRACT

Introduction. Failed back surgery syndrome may be secondary to surgery or due to a preexisting degenerative disease. Magnetic resonance with gadolinium helps to evaluate post-surgical changes in the epidural space and in the rachidian canal, as well as persistence or recurrence of a spinal disc herniation.
Objective. Show the usefulness of magnetic resonance to evaluate the causes observed in patients with failed back surgery syndrome.
Material and methods. The most representative cases treated at our center with a 1.5 Tesla resonator were chosen.
Discussion. Magnetic resonance with gadolinium is used to evaluate patients with failed back surgery syndrome. The most common causes of this syndrome are: persistent or recurrent spinal disc herniation, arachnoiditis, epidural fibrosis, and spondylodiscitis, among others. It is important to know the type of surgery and time of evolution because the findings will not be the same at one week as they will at 6 months.
Conclusion. Magnetic resonance is the best method to evaluate changes from back surgery, mainly to differentiate between epidural fibrosis and persistent or recurrent spinal disc herniation, the most common complications in failed back surgery syndrome.
