Endovascular Embolization of Left-Sided Varicocele: Outcomes by Venographic Anatomy and Coil-Adjunct Strategy.

Technical success was 100% and clinical success was 97.8% (45/46).

Minor adverse events occurred in 2 of 46 patients (4.3%); no major adverse events occurred.

Complex anatomy (Types 3-5) was present in 56.5%.

In exploratory comparisons, clinical success was 94.7% with coil + glue vs 100% with coil + polidocanol (P = .41); recurrence and adverse event rates did not differ significantly by embolic strategy or anatomic complexity.
