Summary
Preoperative transcatheter arterial embolization effectively reduces bleeding during surgery for non-spine bone metastases from hepatocellular carcinoma. While procedures may be longer, this embolization aids in minimizing blood loss.
Area of Science:
- Oncology
- Interventional Radiology
- Surgical Oncology
Background:
- Hypervascular bone tumors often undergo preoperative embolization to reduce surgical risks.
- Limited data exists on its use for non-spine bone metastases from hepatocellular carcinoma (HCC).
Purpose of the Study:
- To evaluate the impact of preoperative embolization on blood loss and surgical outcomes.
- To assess its efficacy in patients with non-spine bone metastases from HCC.
Main Methods:
- Retrospective review of 75 patients with HCC bone metastases (pelvis and extremities).
- Comparison between 22 patients who received preoperative embolization (Group A) and 53 who did not (Group B).
Main Results:
- Group A had a higher proportion of pelvic metastases and longer operative times.
- A significantly smaller decrease in hemoglobin was observed in Group A post-surgery (P=.017).
- No significant differences in estimated blood loss, transfusions, or hospitalization length between groups.
Conclusions:
- Preoperative embolization is effective in reducing intraoperative bleeding for non-spine HCC bone metastases.
- Surgical procedures involving embolization tend to be more extensive and longer.
