Procedure Guide


Indications

  • Symptomatic (scrotal pain/swelling) varicoceles, occurs in 10-15% of men

  • Infertility or adolescent vaicocele with testicular atrophy

  • Post-surgical ligation recurrence

Grading:

  • Grade 1 - palpable only with valsalva

  • Grade 2 - non-visible but palpable upon standing

  • Grade 3 - visible on gross inspection


Contraindications

  • No safe access

  • Uncorrected coagulopathy (INR >2.0, Plts <50K)


Efficacy and alternatives

  • Embolization: ~100% technical success. Most patients can work the following day.

    • 30-35% of couples with male-factor infertility are able to achieve normal pregnancy.

  • Similar efficacy for microsurgical ligation/varicocelectomy. May be superior for bilateral varicoceles.


Pre-procedure care

  • Nothing specific necessary for young otherwise healthy patient

  • Labs for older/sicker patients: CBC, BUN, Cr, PT/INR


Procedure

  • Internal jugular, greater saphenous, or common femoral vein access.

  • Advance working wire (e.g. Amplatz) into IVC.

  • Advance curved catheter (C2, MPA, Berstein) and exchange working wire for angled glidewire.

  • Select the left renal vein. Optional venogram +/- Valsalva to assess for gonadal venous reflux.

  • Select left gonadal vein and perform a venogram +/- Valsalva to assess for gonadal venous reflux.

  • Advance microcatheter (e.g. 2.7 ProGreat) to level of inguinal ligament (~roof of acetabulum)

  • Embolize up to origin from left renal vein via coils, glue, 3% STS foam, etc

    • Many do coil-foam-coil but some advocate for glue to fill small collaterals that can lessen effectiveness if not embolized.

    • Systematic review found no difference in complication rate between embolics. Recurrence rate was lowest for glue (4%) and highest for sclerosant alone (11%) but less follow up for glue in included studies.

  • Post-embolization venogram to identify and embolize any capsular, hilar, or colic collaterals.

  • Select right gonadal vein, often arising from IVC or right renal vein.

  • Repeat process described above with venography and embolization.

  • Remove catheter/sheath and achieve hemostasis.


Complications

Infection, bleeding, mild-transient scrotal pain, coil migration, venous perforation, phlebitis


Post-procedure care and follow up

  • Monitor 2-3 hrs post-procedure

  • Heat pack/pad + NSAID for scrotal pain/swelling or back pain (~10% of patients)

  • No lifting >20 lbs for 48 hrs post-procedure

  • 3 month follow up US

  • 1-3 month clinic follow up
