  • Title: Pediatric varicocele embolization.
    Author: Lord DJ, Burrows PE.
    Journal: Tech Vasc Interv Radiol; 2003 Dec; 6(4):169-75. PubMed ID: 14767848.
    Abstract:
    Varicocele is a very common condition. Although some patients may have pain, it is usually asymptomatic. Treatment of adolescent and pediatric patients is based on the desire to prevent testicular dysfunction and infertility that may be irreversible in adulthood. Venous embolization of the spermatic vein is an effective and minimally invasive method to occlude the varicocele and is known to improve testicular size and function. Embolization can be optimized by use of sclerosant, such as sodium tetradecyl sulfate (STS) foam or ethanol to permanently occlude the internal spermatic vein. About 10 to 15% of patients have recurrent varicocele after embolization. This is usually due to collateral vessels, such as from the right spermatic vein or the splanchnic veins. Embolizing as low as possible, while preventing pampiniform phlebitis by externally compressing the external inguinal ring, and empiric bilateral embolization appear to have the best outcome for preventing recanalization. Complications of varicocele embolization are uncommon. They include pampiniform phlebitis and venous thromboembolism into the renal vein or pulmonary artery.
