Summary

Transvenous embolization is a common varicocele treatment. Even with competent internal spermatic veins, embolization can succeed by targeting other venous connections.

Area of Science:

  • Urology
  • Interventional Radiology

Background:

  • Varicocele is a common condition often caused by internal spermatic vein incompetence.
  • Transvenous embolization is a primary treatment for varicocele.

Purpose of the Study:

  • To investigate the management of varicoceles when the internal spermatic vein appears competent during venography.
  • To determine if embolization is still viable when alternative venous connections are the cause.

Main Methods:

  • Retrospective review of 165 patients undergoing transvenous embolization for varicocele.
  • Analysis of venographic findings, specifically noting internal spermatic vein valvular competence.
  • Documentation of successful embolization despite initial venographic findings.

Main Results:

Related Experiment Videos

  • In 18 of 165 patients (10.9%), venography showed competent internal spermatic veins.
  • In these cases, varicocele was attributed to incompetent anastomotic connections.
  • Embolization was successfully performed in these patients by crossing the competent valve.

Conclusions:

  • Valvular competence of the internal spermatic vein does not preclude successful varicocele embolization.
  • Alternative venous pathways should be investigated and embolized if identified.
  • Embolization procedures should not be terminated solely based on internal spermatic vein competence.
