What Is Embolization Treatment Not every vascular condition requires open surgery to be treated effectively. Varicocele embolization is a minimally invasive treatment used to manage varicocele through image-guided techniques. During the procedure, a small catheter is inserted through a tiny puncture in the skin and guided through the veins. Special materials are then used to block the abnormal veins responsible for the condition. This helps redirect blood flow through healthy veins and improves circulation. To learn whether this procedure may be suitable, speak with Dr Santosh Patil in Pune about varicocele embolization.
