    Author: Janík V, Kolihová E, Peregrin JH, Schlegerová D, Vrána M, Belán A.
    Journal: Cesk Radiol; 1990 Jan; 44(1):44-50. PubMed ID: 2344656.
    Abstract:
    The experiment in four dogs verified a suitability of the Czechoslovak preparation Vilan 500, a copolymer of polyvinyl acetate - polyvinyl alcohol in 93% ethanol, for the embolism of venous vascular bed in the percutaneous, transfemoral catheterization way. In all four cases there was a complete occlusion of embolized spermatic or pararenal veins, verified by a control angiography after one hour and after three months. The prepared venous samples were also examined by histology and changes indicating intraluminar thrombotization and subsequent fibrous reconstruction were observed. In view of the results reached it may be concluded that the catheterization technique and the use of Vilan 500 is suitable as an alternative of non-surgical solution of varicocele.
