Objective:
Thoracic level localization in the treatment of thoracic spine problems is more challenging than other spinal regions. The purpose of this study was to prove the reliability of pedicular spinal needle placement under computed tomography guidance before thoracic spine surgery and to reduce the margin of error, surgery time and operating room radiation exposure during thoracic spine and spinal cord surgery.
Methods:
Fourteen patients undergoing posterior aproach to the thoracic spine and/or spinal cord related lesions were investigated. Spinocaths were placed under CT guidance, into the pedicle of the relevant vertebra, at the same day or the night before surgery. The surgical field is prepared as usual, and a spinocath is placed to the relevant thoracic pedicle under CT guidance.
Results:
Intraoperative level localization was more reliable and easier in patients undergoing preoperative CT-guided marking in surgeries on the thoracic region performed for various reasons. Shorter preoperative preparation and intraoperative anesthesia times, a decrease in number of fluoroscopic images taken intraoperatively, and no spinal mislocalizations were observed.
Conclusion:
The results obtained suggest that localising the level with preoperative CT before all types of thoracic surgery is a safe, reliable, and useful method for thoracic spine surgery.
