Preoperative transarterial Embolisation in bone tumors

Figure 8 Preoperative embolisation in a metastatic lesion from renal cell carcinoma in an elderly male. A: Fifty-two-year-old male with renal cell carcinoma (RCC) and a large destructive lesion of the right femoral metaphysis extending to involve the proximal diaphysis. Preoperative Embolisation was planned to reduce tumour vascularity. Metastases from thyroid carcinoma and RCC are highly vascular; B and C: Right common femoral angiogram revealed marked tumor vascularity; D: Delayed phase image shows profound tumor vascularity; E: Embolisation was performed with 300-500 μm polyvinyl alcohol particles and marked reduction (90%) in tumour vascularity was achieved.
