METHOD FOR SURGICAL MANAGEMENT OF EPIDURAL SPINAL ABSCESS (VERSIONS) Russian patent published in 2015 - IPC A61B17/00 A61M27/00 

FIELD: medicine.

SUBSTANCE: translaminar holes 5-8 mm in diameter are formed in vertebral arches throughout the entire epidural abscess. An inflow-outflow washing system is configured in the form of two hollow, one-lumen polyvinylchloride tubes with perforations along the full length of a working portion. The first tube is installed into the epidural space throughout the epidural abscess. Ends of the first tube are brought out through the formed upper and lower translaminar holes through additional skin counterapertures. The second tube is installed above the vertebral arches, while the ends are delivered into the subfascial space through the second additional skin counterapertures in the upper and lower corner of the postoperative wound. The upper end of the second tube is capped, whereas an vacuum apparatus is attached onto the lower end. The postoperative period involves supplying an antiseptic solution through the first tube, and the epidural abscess cavity is washed. The solution together with serosanguinous and residual purulence flows from the epidural space through the translaminar holes into the subfascial space and is collected by the second tube. According to the second version of implementing the method, the interlaminar windows are formed throughout the entire epidural abscess by dilating the interlaminar spaced by edge resection of the spinal arches.

EFFECT: invention reduces intraoperative injuries, risk of postoperative complications and recurrences that is ensured by forming the translaminar holes in the arches and providing the adequate outflow of the washing fluid.
