Some tumors like renal cell carcinoma are very vascular and their surgical resection can be bloody. Some surgeons electively embolize such tumors before surgery to reduce intra-operative bleeding.
This patient had carcinoma of his left kidney and I embolized it with dry alcohol and gel-foam before it was removed the next day. The first image is a contrast-enhanced transverse CT scan of the tumor showing a large deformed left kidney and the second image, angiogram of the tumor before I embolized it. The third image is angiogram of the left renal artery after embolization showing lack of opacification of the kidney.
