Internal Spermatic Vein to Superficial Epigastric Vein Microsurgical Bypass in Varicocele Treatment.

INTRODUCTION

Identification and preservation of testicular artery and lymphatic vessels during microsurgical varicocelectomy can be tedious if adhered encompassing venous network is encountered. A venous bypass from internal spermatic to saphenous or inferior epigastric vein, that have been described for varicocele treatment, may be used in such situations. This paper describes a simplified modification of the venous bypass technique that reroutes the testicular blood to the superficial epigastric vein, which can easily be found in the incisional wound. Surgical technique and anastomotic patency test are described, and indications and results are discussed.

MATERIALS AND

METHODS

During 2020 and 2021, 32 adolescent patients underwent microsurgical varicocelectomy. In eight patients additional microsurgical testicular vein-superficial epigastric vein microvascular bypass was done. The indication for bypass was difficult identification of testicular artery and/or lymphatic vessels due to adhered venous plexus.

RESULTS

Varicocele resolution was noted in all eight patients with clinical and/or semen analysis improvement. There were no complications or recurrences. Average length of procedure was 65 minutes. All patients were discharged within 24 hours and no antiplatelet or anticoagulant therapy was used.

CONCLUSION

Testicular vein to superficial epigastric vein anastomosis is a useful and simplified venous bypass technique that reroutes the blood from the pampiniform plexus to the femoral vein. It can be done as an adjunct to microsurgical varicocelectomy in selected patients through a standard incision.
