Summary
A novel needle localization technique using myelography and CT scans accurately identifies herniated thoracic discs. This method improves surgical precision and efficiency for video-assisted thoracoscopic microdiscectomy.
Area of Science:
- Neurosurgery
- Thoracic Surgery
- Minimally Invasive Procedures
Background:
- Video-assisted thoracoscopic microdiscectomy is effective for thoracic disc herniation (T4-T12).
- Accurate level localization remains a challenge, risking incorrect surgical site exploration.
Purpose of the Study:
- To present a reliable and time-efficient technique for localizing thoracic disc herniations.
- To improve the safety and accuracy of video-assisted thoracoscopic microdiscectomy.
Main Methods:
- 86 consecutive cases utilizing pre-operative intrathecal contrast administration.
- Computed tomography (CT) scans in prone position followed by endoscopic needle advancement.
- Identification of the correct pathological level via endoscopic visualization of the inner wire.
Main Results:
- Myelo-CT provides detailed anatomical information for surgical planning.
- Needle localization successfully obviates the need for fluoroscopy.
- The technique is efficient, saving operating room time.
Conclusions:
- Needle localization is a simple, safe, and effective adjunct for thoracoscopic microdiscectomy.
- This method enhances surgeon focus on the surgical procedure.
- Improved localization contributes to better surgical outcomes for thoracic disc herniation.
