Management of High-Output Chyle Leak after Harvesting of Vascularized Supraclavicular Lymph Nodes

Summary: Vascularized lymph node transfer is a physiologic microsurgical technique used for the treatment of lymphedema. As vascularized lymph node transfer is becoming more common, it is essential that one is aware of all potential complications associated with vascularized lymph node transfer and know how to avoid and manage them when they do occur. The authors recently encountered a complication after supraclavicular vascularized lymph node transfer that has not been previously reported. A patient developed a recalcitrant high-output (>500 ml/day) chyle leak in the neck donor site after supraclavicular vascularized lymph node transfer harvest. In this article, the authors share their experience with massive chyle leak and review the management strategies of how to effectively avoid and treat this potentially dangerous complication. This review of a previously unreported complication of supraclavicular vascularized lymph node transfer is timely and important, as this procedure is increasingly being offered to patients, and surgeons performing these procedures should be familiar with effectively managing this potentially dangerous complication.
