A Case of Medical Leech Therapy for Venous Congestion Following Forearm Flap Reconstruction

Leeches have been used for medical treatment for at least 2,500 years. Plastic surgeons have recently begun to use leeches to reduce venous congestion after flap reconstruction. However, few reports of leech use in the oral region have been published. We report a case of medical leech therapy used to treat venous congestion after forearm flap reconstruction for oral cancer. A 67-year-old female was diagnosed with squamous cell carcinoma of the left tongue margin(cT2N0M0, Stage Ⅱ). The patient underwent tracheostomy, supraomohyoid neck dissection, hemiglossectomy, and reconstruction using a free forearm flap under general anesthesia. Venous congestion in the forearm flap was detected 21 hours postoperatively, and reanastomosis of the flap was performed. However, venous congestion continued after revision surgery. Therefore, we introduced medical leech therapy to treat the venous congestion. Leeches were used twice daily for 5 days, and the total hematophagy volume was 21.6 g. After leech treatment, continuous bleeding from the skin flap decreased and skin color improved. The medial skin flap survived, and the patient was able to eat 13 days after the initial operation. The rest of the treatment has been uneventful to date without dysfunction of the skin flap.
