Аннотация:Epidural fibrosis is formed around the dural sac and the neurovascular structures of the vertebral canal in the postoperative period. It is one of the common causes of Failed Back Surgery Syndrome (FBSS) syndrome. It occurs in 100 % with repeated surgical interventions, in connection with which the operational technique of working with the dural sac and on neurovascular structures of the vertebral canal becomes more complicated and sometimes leads to their damage. Despite the development of modern technologies, in medicine, there are no specific and sensitive methods for diagnosing epidural fibrosis, which would help to establish the correct diagnosis in 100 % of cases. The review summarizes and systematizes domestic and foreign literature data on etiology, pathogenesis and pathophysiology of cicatricial and epidural adhesion. The analysis includes 22 sources of Russian literature and 28 sources of foreign literature.
