Treatment of secondary scrotal and lower extremity lymphedema using combined pedicled lymph node transfer and lymphaticovenous anastomosis: A case report

Abstract

Combined secondary scrotal and lower extremity lymphedema is an infrequent complication of radical excision of urogenital cancers associated with pelvic lymphadenectomy. Scrotal lymphedema is usually psychologically distressing, and difficult to treat. We report a case of a 41-years old male who presented with scrotal and left lower extremity lymphedema after radical prostatectomy and pelvic lymphadenectomy successfully treated with pedicled superficial inguinal lymph node (SILN) transfer and lymphaticovenous anastomosis (LVA) restoring the lymphatic drainage. The flap consisted of subscarpal adipofascial tissue between the level of the inguinal ligament and the groin crease measuring 11 × 7 cm. The flap composed of afferent lymphatics from the lower abdomen, lymph nodes, and fatty tissue without skin, the right-sided flap was transposed to the root of scrotum while the left one to the proximal left thigh, then two-level LVA were performed in the left extremity. The surgery went uneventful with no postoperative complications. At a 9 month follow-up, there was a significant reduction of the scrotal volume with a reduction of excess volume of the lower extremity from 49.6 to 9.4% compared with the healthy side. No cellulitis was reported during the follow-up period with improvement in the patient's clinical symptoms and quality of life. We believe that pedicled superficial inguinal lymph node flap together with LVA is a reliable and safe treatment option for either scrotal or lower extremity lymphedema following pelvic cancer treatment.
