Summary
Combined microwave ablation (MWA) and vertebral augmentation (VA) effectively treats painful spine metastases with posterior wall defects. This safe procedure significantly reduces pain and improves patient function.
Area of Science:
- Oncology
- Neurosurgery
- Interventional Radiology
Background:
- Spinal metastases often present with posterior wall defects, causing significant pain and disability.
- Current treatment options may not adequately address the complex biomechanical and oncological challenges of these lesions.
Purpose of the Study:
- To evaluate the efficacy and safety of combined microwave ablation (MWA) and vertebral augmentation (VA) for treating spinal metastases with posterior wall defects.
Main Methods:
- A retrospective review of 67 patients with painful spine metastases and posterior wall defects who underwent combined MWA and VA.
- Assessment of procedural effectiveness using Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) scores pre- and post-procedure.
Main Results:
- The procedure was technically successful in all patients, with significant VAS score reductions observed at all follow-up points (p < 0.01).
- Mean ODI scores were significantly lower post-procedure compared to baseline (p < 0.001).
- Transient nerve injury occurred in 2 patients; asymptomatic bone cement was observed in 43.5%.
Conclusions:
- Combined MWA and VA is an effective and safe treatment modality for painful spinal metastases involving posterior wall defects.
- This combined approach offers significant pain relief and functional improvement for patients.
