Transvenous Sclerotherapy of the Gonadal Veins for Treatment of Varicocele: Long-Term Results

Abstract

Percutaneous occlusion of the spermatic vein has been performed on 136 consecutive patients with varicocele scroti during the last six years. The authors report their long-term results on the first 119 cases to have a follow-up of at least six months. Occlusion of the insufficient gonadal vein is induced by the selective transcatheter injection of sclerosing agent with local anesthesia. Their patients are always evaluated before and after the procedure by Doppler examination. A spermiogram is done before the procedure and after six months. In this series they registered only 4 recurrences with no major complications.
