A varicocele is a cluster of enlarged veins in the scrotum that causes blood to accumulate and increased pressure in the veins. Varicoceles are treated with embolization, during which abnormal veins are permanently closed, redirecting blood through normal venous channels.
Varicocele Embolization is a minimally invasive procedure used to shut off the blood supply in a varicocele. An interventional radiologist uses X-ray imaging to guide a small catheter to the abnormal vein. Contrast dye is injected into the vein to visualize all pathways leading to the varicocele; then, the affected veins or “pathways” are permanently closed, and blood is redirected to normal venous channels.
