  • Title: [Sclerotherapy of the internal spermatic vein in varicocele. Significance of normal anatomical variants].
    Author: Lenz M, Hof N, Strotzer M, Brandstetter K, Bautz W.
    Journal: Rofo; 1994 Dec; 161(6):531-9. PubMed ID: 7803777.
    Abstract:
    During a period of four years, 386 patients with left sided varicoceles were treated by sclerotherapy of the left internal spermatic vein. This was successful in 93.8%. The most common complication was perforation of the vein in 6.2%. Technical success and complications depended on anatomical variations. Of particular significance was Bähren type IVb (competent main vein, incompetent collaterals) which occurred in 18.9%. This accounted for 66.5% of all perforations and 54.2% of unsuccessful interventions. The recurrence rate was 3.8%.
