Preoperative embolization of primary bone tumors: A case control study

Area of Science:

• Oncology
• Interventional Radiology
• Orthopedic Surgery

Background:

• Primary bone tumors present significant surgical challenges, often involving substantial intraoperative blood loss and transfusion requirements.
• Effective management strategies are crucial to minimize surgical risks and improve patient outcomes.

Purpose of the Study:

• To evaluate the safety and effectiveness of preoperative embolization for primary bone tumors.
• To assess the impact of embolization on intraoperative blood loss, blood transfusion volume, and surgical duration.

Main Methods:

• A cohort study comparing patients who underwent preoperative embolization (n=26) with a control group (n=28) with similar primary bone tumors.
• Patients in the embolization group were operated within 0-48 hours post-embolization.
• Statistical analysis compared blood loss, transfusion volume, and surgical time between the groups.

Main Results:

• The embolization group showed significantly lower mean intraoperative blood loss (1300 mL vs. 1800 mL, P < 0.001) and blood transfusion volume (700 mL vs. 1400 mL, P < 0.001) compared to the non-embolization group.
• Surgical time did not differ significantly between the two groups.
• No complications related to angiography or embolization were observed.

Conclusions:

• Preoperative embolization is a safe and effective adjunct in the surgical management of primary bone tumors.
• Embolization demonstrably reduces intraoperative blood loss and the need for blood transfusions.
• This interventional radiology technique enhances surgical outcomes for bone tumor resection.
