Introduction:
Spinal metastases secondary to renal cell carcinoma are associated with significant intra-operative blood loss. Our aim was to assess if embolisation reduced the intra-operative blood loss and transfusion requirement.
Methods:
We performed a retrospective cohort study of 25 patients undergoing surgery between 2003 and 2011.
Results:
14 underwent pre-operative embolisation; 11 did not. There was no significant difference in intra-operative blood loss, 1336 ml vs 1492 ml in the non-embolised (p value = 0.116). 43% of embolised patients required an intra operative blood transfusion vs 27% in the non-embolised.
Conclusion:
Our results suggest that not all patients with spinal metastatic renal carcinoma require pre-operative embolisation.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
