METHOD OF PLASTIC SURGERY OF VENTRAL DEFECT OF DURA MATER OF SPINAL CORD Russian patent published in 2023 - IPC A61B17/00 A61B17/56 

FIELD: medicine; neurosurgery.

SUBSTANCE: invention can be used in surgical treatment of patients with ventral herniations of the spinal cord. To do this, the base of the spinous processes at the access level, the ipsilateral vertebral pedicle to the outer cortical layer, the medial and middle thirds of the articular facets, the base of the transverse process are additionally resected, the dura mater is opened with a longitudinal linear incision on its lateral surface 5 mm above the level of origin of the roots, preserving the arachnoid membrane. After crossing the odontoid ligaments at the access level, the arachnoid membrane is displaced laterally until the ventral dura defect and spinal cord herniation are visualized. The hernial protrusion of the spinal cord is mobilized. The ventral defect of the dura mater is sutured with a continuous enveloping suture using Prolene 5-0 suture material. The suture zone is sealed with a Tachocomb plate; after performing the plastic surgery of the ventral defect, the preserved arachnoid membrane is returned to its original position, covering the plastic zone. The dura mater is hermetically sutured with a continuous wrapping suture using Prolene 5-0 suture. The wound is sutured in layers.

EFFECT: method will ensure a reduction in trauma risk and an increase in the tightness of the repair of the ventral dura mater defect by preserving the arachnoid membrane of the spinal cord.
