Vertebral corpectomy (vertebral body resection), partial or complete, for excision of intraspinal lesion, single segment; intradural, lumbar or sacral by transperitoneal or retroperitoneal approach

Vertebral corpectomy is a surgical procedure that involves the removal of a vertebral body along with the intervertebral discs situated above and below the affected vertebra. This operation is specifically performed to excise an intraspinal lesion or tumor that is located within the spinal canal and is either within or extending into the dura mater, which is the protective covering of the spinal cord. The procedure is limited to a single segment of the lumbar or sacral spine, making it a targeted intervention for addressing localized spinal pathologies. The approach to the surgery can be either transperitoneal, which involves an incision in the abdomen and entry into the peritoneal cavity, or retroperitoneal, which requires a flank incision to access the spine from the side. During the operation, careful dissection is performed to protect vital structures surrounding the spine. The surgical team utilizes a microscope to enhance visibility and precision while removing the intervertebral discs and the vertebral body, allowing for thorough exploration and excision of the lesion or tumor. If the lesion is found to be within or extending into the dura, the dura is incised to facilitate complete removal. Post-excision, the dura is repaired, and additional procedures such as bone grafting and spinal instrumentation may be performed to ensure stability and promote healing in the affected area.
