Summary
Surgical approaches to the cervico-thoracic junction (CTJ) were evaluated. The postero-lateral extrapleural approach (PLEA) offers superior exposure with minimal risk, while simple cervicotomy is suitable for specific anterior CTJ conditions.
Area of Science:
- Neurosurgery
- Anatomy
- Surgical Techniques
Background:
- The cervico-thoracic junction (CTJ) involves critical neural and vascular structures.
- Posterior surgical approaches inadequately expose anterior spinal elements.
- Various lateral and anterior approaches have been developed for CTJ access.
Purpose of the Study:
- To discuss indications, anatomical landmarks, and risks of main surgical approaches to the CTJ.
- To compare the efficacy and safety of different surgical access routes.
- To identify optimal surgical strategies for CTJ pathologies.
Main Methods:
- Surgical dissection of the CTJ in ten fresh cadavers.
- Performance of postero-lateral extrapleural approach (PLEA) and antero-lateral thoracotomies.
- Evaluation of anterior approaches, including cervicotomy and sternoclaviculotomy.
Main Results:
- The PLEA provided excellent antero-lateral exposure (T2-T4) with preserved musculature.
- Thoracotomies allowed antero-lateral access but were limited by intrapleural considerations.
- Anterior approaches exposed the anterior cervical and upper thoracic vertebrae up to T4.
Conclusions:
- The PLEA offers the greatest surgical exposure with minimal neurovascular risk.
- Simple cervicotomy is the preferred anterior approach for specific patient anatomies.
- Understanding these approaches is crucial for effective CTJ surgical management.
