[Clinical study of modified one stage posterior approach total en block spondylectomy and spinal reconstruction in the treatment of invasive thoracic vascular tumor].

OBJECTIVE: To explore the surgical method and safety of modified one stage posterior approach total en block spondylectomy combined with pedicle screw fixation and titanium mesh reconstruction for the treatment of invasive thoracic vascular tumor. METHODS: lesions had sensory dyskinesia below the umbilicus, and the muscle strength of both lower limbs was grade Ⅰ-Ⅱ, and the others 11 patients were grade Ⅲ-Ⅳ. All 12 patients underwent one stage posterior approach total en block spondylectomy and the pedicle screw fixation combined with titanium mesh reconstruction under general anesthesia and continuous motor evoked potential (MEP) spinal cord electrophysiological monitoring throughout the operation. The operation time, intraoperative blood loss and transfusion, postoperative pain and recovery of spinal cord function, bone graft fusion, tumor recurrence and other complications were followed up. RESULTS: <0.05). Titanium mesh bone grafts were all fused in phaseⅠ, with an average fusion time of 4.5 months (3 to 7 months). During the follow-up period, there was no tumor recurrence, loosening or breaking of nails, sinking and displacement of titanium mesh. CONCLUSION: Modified one stage posterior approach total en block spondylectomy is an ideal surgical method for the treatment of invasive thoracic vascular tumors, which has a safe, reliable and long lasting efficacy.
