Summary
CT-guided percutaneous marking aids thoracic disc herniation surgery by improving vertebral segment localization. This technique helps prevent accidental removal of healthy discs, enhancing surgical accuracy.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Radiology
Background:
- Thoracic disc herniation surgery presents significant challenges for surgeons, particularly in accurately identifying the correct vertebral level during operation.
- Intraoperative localization of the affected disc space is crucial for successful surgical outcomes.
Purpose of the Study:
- To evaluate the effectiveness and feasibility of using computed tomography (CT)-guided percutaneous marking for precise intraoperative localization of vertebral segments in thoracic disc herniation surgery.
Main Methods:
- A retrospective analysis of eight patients who underwent surgery for thoracic disc herniation between 1986 and 1998.
- Intraoperative localization of disc levels was performed using a biplanar fluoroscopy (BV) system.
Main Results:
- The study identified instances where inaccurate height localization led to the unintended removal of healthy intervertebral discs.
- Despite the challenges, the BV system was employed for localization in all eight cases.
Conclusions:
- The intraoperative application of biplanar fluoroscopy (BV) systems is increasingly utilized for localizing affected intervertebral segments in thoracic disc herniation operations.
- CT-guided percutaneous marking shows promise in improving the accuracy of localization, potentially reducing complications.
