Ans. A: Cremasteric veinVaricocelectomy, the surgical correction of a varicocele, is performed on an outpatient basis.The three most common approaches are inguinal (groin), retroperitoneal (abdominal), and infrainguinal/subinguinal (below the groin).Possible complications of this procedure include hematoma (bleeding into tissues), infection, or injury to the scrotal tissue or structures.In addition, injury to the aery that supplies the testicle may occur.An alternative to surgery is embolization, a non-invasive treatment for varicocele.Embolization is an effective treatment for post-surgical varicoceles.
