    Summary

    A modified transfemoral approach for testicular venography and occlusion effectively treated varicoceles. This technique allowed deep coil placement in testicular veins, achieving high success rates for varicocele repair.

    Area of Science:

    • Interventional Radiology
    • Vascular Surgery

    Background:

    • Varicocele, an abnormal dilation of testicular veins, is a common cause of male infertility and scrotal pain.
    • Traditional surgical and radiological interventions for varicocele have varying success rates and complication profiles.

    Purpose of the Study:

    • To evaluate the efficacy of a modified transfemoral technique for testicular venography and occlusion in treating varicoceles.
    • To assess the feasibility of subselective catheterization and deep embolization within the testicular vein and its collaterals.

    Main Methods:

    • A modified transfemoral approach was employed for testicular venography and occlusion in 30 patients with 43 varicoceles.
    • The technique involved coaxial catheterization to achieve subselective access to the testicular vein (TV) and its tributaries.
    • Embolization was performed using coils, alone or with detachable balloons, placed deep within the vessels.

    Main Results:

    • Successful occlusion was achieved in all 17 left-sided varicoceles.
    • A 90% success rate was observed for the 13 right-sided varicoceles.
    • The coaxial technique facilitated deep embolization, indicating its effectiveness in managing complex varicocele anatomy.

    Conclusions:

    • The modified transfemoral technique provides a safe and effective method for varicocele treatment.
    • This approach allows for precise embolization of the testicular vein and its collaterals, leading to high occlusion rates.
    • The technique's ability to facilitate subselective catheterization and deep coil placement enhances treatment outcomes for varicoceles.
