The use of superficial circumflex iliac perforator (SCIP) pedicle vein for lymphovenous anastomosis to treat inguinal lymphatic fistula: A case report.

Abstract

The management of lymphatic fistulas following surgical procedures, in particular after inguinal lymphadenectomy, represents a significant clinical challenge. The current case report shows the novel use of the superficial circumflex iliac perforator (SCIP) pedicle vein for lymphovenous anastomosis (LVA) to treat a chronic inguinal lymphatic fistula in a 58-year-old male patient. This patient had developed a persistent lymphorrhea and wound dehiscence after a right inguinal lymph node biopsy performed for oncological reasons 1.5 months before. Pre-operative assessment with indocyanine green (ICG) lymphography confirmed a substantial lymphatic contribution to the wound discharge, thus guiding the surgical strategy. During the procedure, a pedicled tissue segment containing the SCIV was dissected and utilized to fill the wound's dead space and facilitate LVA with the leaking lymphatic vessel. Notably, a coupler device was employed for the anastomosis due to the large caliber of the lymphatic vessel involved, a technique not commonly reported in lymphatic surgeries. The result of the procedure was successful, with intra-operative ICG imaging confirming the patency of the anastomosis. After surgery the wound healed without complications. This case illustrates the potential of SCIV employment in lymphatic fistula repair in the inguinal region. While further research is needed to validate these findings, this report provides an unconventional approach to a relatively common problem in clinical practice.
