EPIDUROGRAFYYa [annate. (cavum) of epidurale an epidural space + Greek grapho to write, represent; a synonym a peridurografiya] — a method of X-ray inspection of an epidural space using radiopaque substances. Epidural call space between a firm cover of a spinal cord (see) and vertebrae.

AA. Sikarom and Forestye (J. A. Si-card, J. Forestier) by means of lipiodolum entered through a lumbar puncture was made for the first time in 1921. Now apply water-soluble iodinated radiopaque substances (Verografinum, Urografinum, triombrast, Iodamidum, etc.).

AA. it is shown to hl. obr. for detection of hernias of intervertebral disks, commissures and fibrosis of peridural cellulose. For a research use water-soluble triyodirovan-ny radiopaque substances of 8 — 76% of concentration (60 — 76% dissolve solutions with isotonic solution of sodium chloride). At E. it is possible to contrast separately a front and back epidural space. After administration of radiopaque substance make a X-ray analysis in the sagittal and frontal planes and in addition a tomography.

Cervical E. carry out in position of the patient sitting. The puncture of an epidural space is carried out between acanthas With vi — About Un or Cvn — Т^ to feeling of «failure» of a needle. Then through an aspirating needle administer X-ray contrast agent. At lumbar E. the patient lies on one side. The puncture of an epidural space is made between acanthas of the lower lumbar vertebrae (more often

Lm — LIV) or through back sacral openings. Changing position of the patient, contrast an epidural space above or places of a puncture are lower, without allowing hit of drug in subarachnoidal (subarachnoid, T.) space since it can lead to damage of a spinal cord and developing of spasms.

Determine the level and degree of manifestation of a protrusion and a protruded disk (fig.) by the shift and local deformation of a front epidural space. The uniform pushing off of a front epidural space is a consequence of a reactive epidu-rit, total or its incomplete block indicates loss of fragments of an intervertebral disk or the intravertebralny growth of a neurinoma or meningioma of a root of a spinal nerve.
