Summary
A novel C-arm free O-arm navigated biopsy technique effectively obtains adequate tissue samples from spinal pathologies. This advanced imaging method ensures precise targeting for accurate diagnosis, potentially replacing repeat CT-guided or open biopsies.
Area of Science:
- Neurosurgery
- Interventional Radiology
- Oncology
Background:
- Percutaneous biopsy under computed tomography (CT) guidance is standard for diagnosing spinal conditions.
- Needle biopsies can yield inadequate specimens, hindering accurate diagnosis.
- A novel C-arm free O-arm navigated microforceps biopsy technique is presented.
Purpose of the Study:
- To describe a new biopsy technique using O-arm navigation for spinal pathologies.
- To evaluate the effectiveness of this technique in obtaining sufficient diagnostic tissue.
- To present a case study of its application.
Main Methods:
- A patient with T1 vertebra pathology underwent initial CT-guided biopsy yielding insufficient tissue.
- The patient then underwent a C-arm free O-arm navigated biopsy using microforceps.
- Histopathological examination of the O-arm guided sample led to a diagnosis.
Main Results:
- The O-arm navigated biopsy successfully obtained sufficient tissue for diagnosis.
- Small cell carcinoma was diagnosed from the biopsy specimen.
- The patient subsequently received chemotherapy and radiation.
Conclusions:
- C-arm free O-arm navigated biopsy is an effective method for spinal pathologies.
- 3-D imaging allows precise tissue acquisition from specific pathological sites.
- This technique offers a viable alternative to repeat CT-guided or open biopsies.
