For decades, patent blue dye (PBV) has been utilized for sentinel lymph node biopsy and lymphatic mapping in breast cancer and melanoma staging and treatment. Fistulography and intraoperative display of lymphatic vessels for lymphaticovenular anastomosis (LVA) are frequent applications. Although its anaphylactic potential is well described, PBV is used routinely. We present the case of a 71-year-old female patient, who underwent LVA for the treatment of chronic secondary lymphedema and experienced a postoperative anaphylactic reaction including a blue-colored drug-induced maculopapular exanthema after PBV administration. This article aims to raise awareness of potential life-threatening allergic reactions and propose an alternative to PBV.
Keywords: anaphylactic reaction; lymphaticovenular anastomosis; lymphedema surgery; patent blue dye; secondary lymphedema.
