Summary
Preoperative embolization of spinal tumors is a safe and effective procedure. This technique reduces blood loss during surgery, enabling more aggressive removal of cancerous tissue.
Area of Science:
- Interventional Radiology
- Neurosurgery
- Oncology
Background:
- Hypervascular tumors of the spine present significant surgical challenges.
- High intraoperative blood loss can complicate surgical resection.
- Preoperative embolization aims to mitigate these risks.
Purpose of the Study:
- To evaluate the 6-year clinical experience with preoperative embolization of hypervascular spinal tumors.
- To assess the safety and efficacy of this interventional technique.
Main Methods:
- Retrospective review of 14 patients (16-70 years old) undergoing 17 embolization procedures.
- Polyvinyl alcohol particles were used for embolization.
- Lesions spanned the cervical to lumbar spine, including metastatic renal cell carcinoma.
Main Results:
- Successful embolization in all patients with no procedure-related complications.
- Median estimated blood loss during subsequent surgery was 1.6 L.
- Embolization facilitated postponed surgery and enabled successful resection in previously complicated cases.
Conclusions:
- Preoperative embolization is a safe adjunctive treatment for vertebral metastases before surgical resection.
- Careful monitoring minimizes complications.
- Devascularization improves the ability to resect tumor burden aggressively.
