  • Title: [Failed sclerotherapy trials with the V. spermatica interna. A retrospective analysis in 1141 patients with idiopathic varicocele].
    Author: Bähren W, Biehl C, Danz B.
    Journal: Rofo; 1992 Oct; 157(4):355-60. PubMed ID: 1391838.
    Abstract:
    From July 1988 until December 1990 1141 patients with left-sided idiopathic varicocele underwent phlebography of the spermatic internal vein, and percutaneous sclerotherapy with sodium morruate (Varicocid) was intended to be performed. In 125 of these patients sclerotherapy was not feasible. The reasons for this were analysed in a retrospective study. According to the anatomical situation of the spermatic vein, there were significant differences in technical success. In case of incompetent valve of the spermatic vein at the renal origin (type I, 2A, 3, 4A), selective probing and following sclerotherapy was possible in 97%. Anatomic variations with competent valve of the spermatic vein (type 0, 2B, 4B) led to difficulties in selectively probing the vessel, and sclerotherapy was feasible in only 72.7%. In these angiographically difficult cases, spasm of the spermatic vein and/or perforation prevented sclerotherapy in 29 of 125 patients.
