Pre-operative or palliative embolisation of renal tumours is an established procedure. A variety of embolic agents including gelfoam, ivalon, steel coils and silastic spheres have been used. However all particulate emboli have inherent disadvantages such as recanalisation and formation of collateral tumour vessels (these emboli only block the small and medium sized arteries, causing only partial tumour infarction and leaving viable areas of the capillary bed). There is also the danger of reflux embolisation of other organs. In comparison, absolute ethanol offers important advantages; these are (1)being a fluid it diffuses into the entire capillary bed and produces instantaneous complete, permanent tumour infarction, minimising the possibility of tumour revascularisation, (2) even if accidental reflux occurs, it is immediately diluted by the large aortic blood flow and hence the safety of the procedures is enhanced, (3) ease of administration, (4) easy availability, (5) economical. We report our preliminary experience with this technique in five cases.
