Varicocele embolization is often preferred over traditional surgery (varicocelectomy) for varicoceles because it’s a minimally invasive procedure.

The Varicocele Embolization Procedure

A radiologist performs embolization for varicoceles through a series of precise, image-guided steps.

First, the patient is positioned on an X-ray table, and the skin at the access site (typically the groin or neck) is sterilized and numbed with local anesthesia.
The radiologist then makes a tiny incision and inserts a thin tube called a catheter into a blood vessel.
Using real-time X-ray imaging (fluoroscopy), the radiologist carefully guides the catheter through the blood vessels to the internal spermatic vein, which is the source of the varicocele.
Once the catheter is positioned within the abnormal veins, the radiologist injects contrast dye to visualize the varicocele and identify the specific veins that need to be blocked.
Embolic agents, such as small metal coils, sclerosing liquid, or plugs, are deployed through the catheter to block the blood flow in the enlarged veins. This redirects blood flow to healthy veins, causing the varicocele to shrink.
After confirming successful blockage, the catheter is removed, and a small bandage is applied to the skin incision.

Recovery After Varicocele Embolization

The procedure typically takes 1-2 hours, and patients can usually go home the same day with minimal recovery time compared to surgical approaches. Side effects may include discomfort, bruising or swelling, inflammation, lower back pain, and nausea. These are typically minor and temporary.
