Abstract
INTRODUCTION: For successful lymphaticovenous anastomosis (LVA), it is important to create anastomoses with high flow to maintain patency. To ensure that this can be achieved, we compared the efficacy of a modified intraoperative distal compression (IDC) technique with the conventional no compression (NC) method for lower limb lymphedema.
PATIENTS AND METHODS: In the IDC group, compression was applied to an area of the foot distal to the first LVA site. After completion of the first LVA, the distal compression was extended over the first LVA site to the distal end of the second LVA site.
RESULTS: There was no significant difference between the IDC (n = 25) and NC (n = 25) groups in detection rate. However, significant differences were observed in lymphatic vessel diameter and LVA success rate. No intraoperative anastomotic obstruction was seen at the conclusion of surgery. Intraoperative congestion with blood was detected in lymphatic vessels in 8 of 79 anastomoses (10.1%) in the NC group, but not in any cases in the IDC group (p = 0.002). There was a significant between-group difference in the rate of improvement in lymphedema between the IDC (16.1±3.6) and NC groups (14.0±3.4; p = 0.03).
DISCUSSION: IDC during LVA is thought to increase lymph flow in larger caliber lymphatics, leading to a high success rate and a low rate of venous reflux. IDC is beneficial when performing LVA.
