Varicocele Treatment

How the Procedure Works

Interventional radiologists at AUNC perform the procedure in an outpatient setting using local anesthesia, avoiding the need for general anesthesia or surgical incisions in the groin or abdomen.

1. Vascular Access: A tiny needle puncture is made, typically in the vein in the leg.
2. Catheter Guidance: Using real-time X-ray (fluoroscopy), a thin catheter is advanced through the venous system down into the left or right gonadal vein.
3. Venography: Contrast dye is injected to map the abnormal, dilated venous channels and identify any collateral pathways contributing to the varicocele.
4. Embolization: The physician deploys specialized mechanical micro-coils to permanently close off the faulty gonadal vein. By blocking this reflux pathway, blood is safely redirected to healthy alternative veins, relieving pressure on the scrotal pampiniform plexus.

Ideal Candidates

• Men experiencing symptomatic varicoceles causing chronic scrotal heaviness, pain, or aching that worsens with prolonged standing or physical activity.
• Young men or adults experiencing progressive testicular atrophy (shrinkage) due to a varicocele.
• Patients undergoing fertility evaluations where a varicocele is identified as a contributing factor to abnormal semen parameters.
• Individuals seeking an alternative to traditional open or laparoscopic surgical ligation, wishing to avoid general anesthesia and surgical scars.

Key Benefits

• Minimally Invasive with No General Anesthesia
• Bilateral Treatment Capability
• Outpatient Procedure

Potential Risks and Side Effects

Varicocele embolization is exceptionally safe, but patients should be aware of a few minor and temporary side effects:

• Mild Aching: A dull ache in the flank, lower abdomen, or scrotum is common for the first 24 to 48 hours as the veins thrombose, easily managed with over-the-counter pain medications.
• Access Site Bruising: Minor localized bruising or tenderness at the catheter entry site in the groin or neck.
• Low-Grade Fever: A transient, mild elevation in temperature over the first couple of days due to the body’s natural inflammatory response to vein closure.
• Recurrence or Persistence: A small percentage of patients may experience persistent or recurrent varicoceles due to the opening of collateral blood vessels, which can be addressed with a repeat embolization if necessary.

Patient Recovery and Follow-Up

• Immediate Recovery: Patients rest in the recovery area for a brief observation period and are sent home with instructions to avoid heavy lifting or strenuous athletic activity for about three to seven days.
• Symptom Resolution: Gradual shrinkage of the varicocele and relief of aching pain typically occur over the course of several weeks as the pooled blood clears and surrounding tissues adapt.
• Fertility and Follow-Up: For patients pursuing fertility improvements, follow-up semen analyses are typically scheduled three to six months post-procedure to evaluate changes in sperm count, motility, and morphology.
