The mainstay of treatment for this condition within the field of interventional radiology is varicocele embolization. An embolization, within the context of this procedure, results in the interruption of venous blood flow. The interruption of blood flow abates venous dilation of blood that can lead to impaired testicular temperature regulation and theoretically improve infertility. The physician accesses the dilated scrotal veins with a small catheter via a vein in the groin and embolize the varicocele. Patients often tolerate this procedure well and are able to return home the same day.
