Percutaneous sclerotherapy of the internal spermatic vein for varicocele through an open ended guide wire.

Percutaneous sclerotherapy of the internal spermatic vein through an open ended guide wire was performed in 50 patients with left sided varicocele. The procedure was successful in 47 patients, without major complications. Percutaneous sclerotherapy through an open ended guide wire offers the advantage of very distal and superselective catheterization with complete embolization of the internal spermatic vein, its side branches and parallel collateral channels. Further follow-up hopefully will confirm the reduction of recurrence rate in our patients.
