Percutaneous Full Endoscopic Interlaminar Decompression Combined with Percutaneous Vertebroplasty in Treatment of Thoracic Vertebral Tumors.

Abstract

Separation surgery is a good alternative as a minimally invasive procedure in the treatment of oncological disease. We applied percutaneous full endoscopic interlaminar decompression (PEID) with vertebroplasty in treatment of thoracic tumors to avoid the morbidity associated with conventional approaches. Between May 2023 and June 2025, 6 patients with thoracic vertebral tumors (from T5 to T12) underwent PEID. The patients were administered general anesthesia and positioned in the prone position. PEID with vertebroplasty was performed using the interlaminar approach. The patients included 3 women and 3 men with a mean age of 53.3 ± 9.7 years (range, 44-66 years). There were improvements in cord compression findings, and mean visual analog scale scores improved from 6.5 ± 1 preoperatively to 3.5 ± 1.1 postoperatively. Pathology showed lymphoma in 2 patients, metastasis in 2 patients, cavernous hemangioma in 1 patient, and plasmacytoma in 1 patient. Mean surgical time was 101 ± 18 minutes. In this study, we defined a full endoscopic interlaminar separation technique, PEID, that we applied in combination with vertebroplasty in patients with tumors in the thoracic vertebra levels.
