[Value of percutaneous sclerotherapy in the treatment of varicocele. Technic and results]

Since December 1983, percutaneous transvenous retrograde sclerotherapy of the internal spermatic vein was performed successfully, without complications in 37 patients. The administration of the sclerosing agent through a coaxially balloon catheter specifically inserted into the spermatic vein caused therapeutic hardening. The effectiveness of the treatment was endorsed by subsequent checks by clinical and radiological examinations.
