Brief Summary

Vertebra is one of the most common site of metastatic disease, which may cause severe pain or neurological deficit. Decompressive surgery or radiation therapy are of limited efficacy and recurrence is very likely. Debulking surgery usually has better local control and survival benefit. However, debulking surgery often accompany with massive blood loss, which may cause hemorrhagic shock or death. It is known that intraoperative blood loss is associated with tumoral vascularity. However, there is current no objective method to evaluate vascularity status. On the other hand, preoperative embolization is considered as major method to decrease blood loss. There is also objective method to evaluate the embolization effect. By our innovative dual energy computed tomography angiography - digital subtraction angiography (CT-DSA), the tumoral vascularity status and embolization effect of spinal tumor can be objectively assessed. We aim to utilize CT-DSA to investigate spinal tumor, in a hope to find out correlation of vascularity status, embolization method, and surgical outcome, which can help individual disease status and tailored treatment decision.
