Varicocele embolisation
A varicocele is an abnormality of the veins of the testicles that results from allowing blood to flow the wrong way. The veins become bigger and more obvious, rather like varicose veins in the leg. Embolisation is a way of blocking these veins and causing the varicocele to disappear, without an operation. When the abnormal veins are blocked the testicles will continue to drain blood normally by other routes.
