Summary
Arterial embolization effectively reduces blood supply to hypervascular bone metastases, offering significant pain relief and serving as a safe adjunctive treatment for cancer patients.
Area of Science:
- Interventional Radiology
- Oncology
- Orthopedic Oncology
Background:
- Bone metastases significantly impact patient quality of life.
- Hypervascular metastases pose challenges for surgical management.
- Arterial embolization is a minimally invasive technique.
Purpose of the Study:
- To evaluate the efficacy and safety of arterial embolization for hypervascular bone metastases.
- To assess the impact of embolization on surgical management and palliative care.
Main Methods:
- Ten skeletal metastases in nine patients underwent selective arterial embolization.
- Embolic materials included polyvinyl alcohol particles, gelatin sponge, and coils.
- Embolization was performed preoperatively in seven cases and palliatively in three.
Main Results:
- Technical success was achieved in all cases with subtotal (>90%) devascularization in five lesions.
- Median intra-operative blood transfusion was 510 mL for operative cases.
- Palliative embolization provided major pain relief in two patients and moderate relief in one.
Conclusions:
- Arterial embolization is an effective and safe adjunctive treatment for hypervascular bone metastases.
- The procedure can reduce intra-operative bleeding and provide pain palliation.
- Embolization facilitates surgical resection and improves patient comfort.
