Non-surgical treatment alternative: Varicocele treatment with interventional radiology.
Percutaneous venous embolization is an interventional radiology method used in the treatment of varicocele. In this procedure, enlarged testicular veins causing varicocele are detected with the help of a catheter entered through a vein in the arm or leg and blocked with metal spirals (coils) or sclerosing agents.
Embolization is called "non-surgical treatment" or "minimally invasive" method because it does not require a surgical incision. The procedure is usually performed under local anesthesia and the patient can return home on the same day.
The patient is laid on the angiography table. The groin or neck area is sterilized and local anesthesia is applied.
A thin catheter is placed via the femoral vein (groin) or jugular vein (neck).
Under fluoroscopy (X-ray) guidance, the catheter is directed to the left renal vein and then to the testicular vein. Enlarged veins are visualized by giving contrast material (venography).
Enlarged veins are blocked with metal spirals (coils), sclerosing agents, or occlusive particles. It is checked that the blood flow has stopped.
The catheter is removed, and pressure is applied to the entry site. The procedure takes a total of 30-60 minutes.
| Feature | Embolization | Microsurgery |
|---|---|---|
| Method | Via vein with catheter | Surgical incision, under microscope |
| Anesthesia | Local | Local, spinal, or general |
| Success Rate | 85-90% | 99%+ |
| Recurrence Rate | 10-15% | <1% |
| Hydrocele Risk | None | <1% (with microsurgery) |
| Procedure Time | 30-60 min | 45-60 min |
| Recovery | 1-2 days | 3-5 days |
| Radiation | Present (fluoroscopy) | None |
| Technical Failure | 5-10% (vein anatomy) | <1% |
Embolization can be evaluated in patients who cannot have surgery due to surgical risks or in patients who have had surgery before and developed recurrence. However, microsurgical varicocelectomy is recommended as the first option in infertility treatment because it offers higher success and a lower recurrence rate.
Microsurgical varicocelectomy is considered the gold standard in infertility treatment. The success rate is 99%+, and the recurrence rate is <1%. Embolization is 85-90% successful and has a 10-15% recurrence rate. Embolization can be evaluated as an alternative in patients who cannot have surgery.
Yes, embolization does not require a surgical incision. A catheter is placed into the vein with a thin needle through the groin or neck area. Therefore, it is called "non-surgical" or "minimally invasive" method.
The recurrence rate after embolization is around 10-15%. This rate is significantly higher than the <1% rate in microsurgery. In case of recurrence, microsurgical corrective surgery may be required.
Yes, fluoroscopy (X-ray) is used during the embolization procedure, and this causes radiation exposure. However, the radiation dose is usually within safe limits. There is no radiation exposure in microsurgery.
