Modified lymph vessel flap transplantation for the treatment of refractory lymphedema: A case report.
Lymph vessel flap transplantation (LFT), lymphaticovenous anastomosis (LVA), or lymph node flap transfer are sometimes used to treat lymphedema that is resistant to conservative treatment. LFT harvested from the contralateral limb has been reported for the treatment of lymphedema. Here we report the use of modified LFT from the abdominal wall for the treatment of refractory lymphedema. Our patient was a 57-year-old patient with secondary lower limb lymphedema was previously treated with conservative therapy and lymphaticovenous anastomosis. We first examined the lymphatic function of the lower abdominal region in the patient using indocyanine green (ICG) lymphography. After confirming the good lymphatic function in the right abdominal region, we harvested the pedicled abdominal adiposal flap containing multiple abdominal lymph vessels and transferred it to the left groin region. The flap (20 × 10 cm2) was based on the superficial circumflex iliac artery perforator. We anastomosed one lymph vessel in the flap to that in the recipient site. We also performed multiple fibrotripsy using a 3-mm-diameter stainless steel stick inserted into small incisions. The postoperative course was uneventful. The circumference measurement was decreased by 2.2-13.5 cm at 1 year after the operation. The lower abdominal region has many lymph vessel networks and is thought to be a less risky donor site in patients with lymphedema than the lower limbs. Thus, LFT may be an option for the treatment of chronic lymphedema. © 2015 Wiley Periodicals, Inc. Microsurgery 36:695-699, 2016.
