[Ethanol injection for embolization of varicocele]

Area of Science:

• Urology
• Interventional Radiology

Background:

• Varicocele, a common cause of male infertility, is often treated surgically.
• Percutaneous embolization is an alternative minimally invasive treatment for varicocele.

Observation:

• Ethanol was utilized for the first time as an embolic agent for varicocele treatment.
• The procedure involved injecting ethanol into the affected spermatic vein via spermatic venography.

Findings:

• Successful embolization was achieved in all five patients.
• Varicocele reduction or resolution occurred in 80% of patients during follow-up.
• One patient experienced recurrence 13 months post-embolization due to catheterization difficulties and ethanol release location.

Implications:

• Ethanol embolization presents a simple, safe, and effective minimally invasive option for varicocele treatment.
• Further research may optimize ethanol delivery techniques to improve long-term efficacy.
• This method offers a promising alternative to traditional surgical interventions for varicocele.
