Summary

This study aimed to address the impact of lymphedema duration on the quality of lymphatic vessels as well as the outcome after LVA using propensity score matching.

Conditions

  • Lymphedema

Interventions

PROCEDURE

lymphaticovenous anastomosis

The patients were under intravenous general anesthesia with local anesthetic infiltration for each incision21. LVs were detected by intradermal injection of ICG into the web spaces between the toes and on the medial and lateral malleoli. ICG flow with linear dermal backflow(DB) patterns was detected immediately using a handheld near-infrared camera. The recipient veins were marked using B-mode echo Doppler, close to the marked linear pattern. In case of DB pattern, the incision was made along the great saphenous vein. A 3 cm incision was made and the lymphatics and recipient veins were identified. All patients underwent supermicrosurgical LVA with 11- 0 nylon sutures using a high-power surgical microscope by a single senior surgeon. LVAs are performed using only antegrade flow lymphatics and lymphaticovenous end-to-end anastomosis (LVEEA) and end-to-side anastomosis (LVESA).
