RESUMO
To investigate the clinic value of microsurgical shunt for the treatment of varicocele combined with asthenspermia,the clinical data and therapeutic method for 3 patients,who conducted the microscope spermatic vein high ligation combined with superficial epigastric vein flow,were retrospectively analyzed.No postoperative complications were found,and the original symptoms and signs were disappeared.All patients were conducted scrotal ultrasound and semen routine after 3 months,and all indexes,including maximum internal diameter of the cord vein (erect position),sperm density,sperm survival rate,sperm deformity rate and sperm forward movement rate,were gradually improved.Consequently,high ligation of spermatic vein combined with vascular bypass surgery under the microscope can block the countercurrent venous blood and establish a new return channel to the testis.Meanwhile,it can also protect the testicular artery and lymph-vessel.It is worth to be spread for the treatment ofvaricocele combined with asthenospermia.
