Vertebral corpectomy (vertebral body resection), partial or complete, for excision of intraspinal lesion, single segment; extradural, thoracic by transthoracic 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 indicated for the excision of an intraspinal lesion, which refers to a growth or tumor located within the spinal canal but outside the protective dura mater, classifying it as extradural. The procedure is performed on a single segment of the thoracic spine, which is the middle section of the vertebral column. Access to the thoracic spine is achieved through a transthoracic approach, necessitating a thoracotomy, which is an incision made in the chest wall. This approach allows for adequate exposure of the thoracic spine, enabling the surgeon to effectively remove the lesion or tumor. The procedure typically involves a collaborative effort between a thoracic surgeon, who handles the exposure of the thoracic cavity, and a spine surgeon, who performs the corpectomy itself. The surgical technique requires careful dissection of the overlying muscles and may involve the resection of one or more upper ribs to facilitate access. Once the thoracic spine is adequately exposed, the intervertebral discs are meticulously removed, followed by the excision of the vertebral body, allowing for the identification and exploration of the lesion or tumor. The ultimate goal of the vertebral corpectomy is to completely excise the lesion while ensuring the stability of the spine through subsequent bone grafting and fusion procedures, if necessary.
