[Successful Embolization for Recurrent Varicocele of Testis after Microsurgical Subinguinal Varicocelectomy]

Microscopic subinguinal varicocelectomy has a recurrence of less than 1%, and varicocele recurrence is supposed to be an uncommon post-surgery adverse event. At present, no guidelines exist for the management of recurrent varicoceles after surgery. In this report, we present two cases of post-surgery recurrent varicocele of the testis. Case_1 : A 23-year-old male patient who had undergone microscopic subinguinal varicocelectomy for a grade 3 varicocele was referred to our hospital because of recurrent varicocele. Retrograde venography revealed the persistence of dilated spermatic veins. The former surgeon preserved the dilated vas deferens vein, and this was considered a possible cause of persistence of dilated spermatic veins. The vein considered as vas deferens vein was actually an internal spermatic vein. Case_2 : A 28-year-old male patient complained of recurrence of varicocele two months after the original operation for a grade 3 varicocele. Internal spermatic vessels were slightly visualized on retrograde venography. The possible cause of persistence in this case was insufficient ligation of the internal spermatic vessels. We performed embolization in both cases of recurrent varicocele. Both cases were successfully treated, and there has been no recurrence. Our findings suggest that percutaneous transcatheter embolization of the testicular vein may be effective in the management of postsurgical recurrent varicocele of the testis.
