Summary
This study introduces an improved percutaneous thoracic spine biopsy technique using specialized trephine needles and patient positioning. The method demonstrated high safety and reliability for obtaining tissue samples from thoracic vertebrae and disks.
Area of Science:
- Medical Imaging
- Surgical Procedures
- Spinal Diagnostics
Background:
- Percutaneous biopsies are crucial for diagnosing thoracic spine pathologies.
- Existing techniques may have limitations in safety and accuracy.
- Minimally invasive approaches are preferred for spinal interventions.
Purpose of the Study:
- To evaluate a novel percutaneous trephine biopsy technique for the thoracic spine.
- To assess the safety, speed, and reliability of the improved biopsy method.
- To compare the new technique with existing procedures for thoracic vertebral and disk biopsies.
Main Methods:
- Forty-one percutaneous trephine biopsies were performed on thoracic vertebral bodies or disks (T-3 to T-12).
- A new set of trephine needles, similar to vascular catheterization, was utilized.
- Specific prone-oblique patient positioning (35 degrees) with fluoroscopic guidance was employed.
- Rib head landmarks were used to guide puncture direction, avoiding pleura and spinal canal.
Main Results:
- The procedure was performed without complications in all 41 cases.
- Out of 40 evaluated cases, 31 yielded true-positive results.
- Six cases provided contributory results, and three were false-negative.
- The technique proved to be rapid and facilitated easy recognition and avoidance of critical structures.
Conclusions:
- Percutaneous trephine biopsy of the thoracic spine using the described technique is safe.
- The improved method is rapid and reliable for obtaining diagnostic tissue samples.
- This technique offers a valuable advancement in minimally invasive thoracic spine diagnostics.
