Brief Summary

Although angiographic embolization has been introduced for preoperative management of spine metastases in 1975 and is suggested today by many authors in the management of such pathologies, it needs to be confirmed by RCT. It is a minimally invasive procedure, not free from complications. The recent meta-analyzes, due to the limited number of patients included are not exhaustive about the effectiveness of embolization in the reduction of the intraoperative bleeding, especially in the context of poor / moderate metastasis vascularization. We want to evaluate the efficacy of preoperative angiographic embolization of intermediate / poor vascularized spine metastases in reducing intraoperative blood loss during excision surgery.

Outcome Measures

Primary Outcomes (1)

  • Intraoperative blood loss

    volume (ml) of intraoperative blood loss volume aspirated from operative field (ml) + differential weight gauze at the end of surgery - dry gauze weight with 1g blood conversion = 0.948ml

    during procedure

Secondary Outcomes (8)

  • Concentration of Hemoglobin pre / post-operative

    24 hours

  • volume of transfused blood (ml)

    intraoperatively

  • Correlation between primary tumor and vascularization

    during angiographic procedure

  • correlation between the type of primary tumor and blood losses

    24 hours

  • technical evaluation of the final result of embolization (total - 100%, subtotal 90-80% and partial 70-50%) in relation to blood losses

    during angiographic procedure

  • +3 more secondary outcomes

Study Arms (2)

Embolization

EXPERIMENTAL

After angiography all metastases with poor/moderate vascularization will be embolized with acrylic glue in the treatment group.

Procedure: Embolization

No embolization

NO INTERVENTION

After angiography all metastasis with poor/moderate vascularization will not be embolized with acrylic glue in the control group
